PAM and its derivatives can be used as efficient flocculants, thickeners, paper enhancers and liquid drag reducing agents. They are widely used in water treatment, paper making, petroleum, coal, mining, metallurgy, geology, light textile, construction and other industrial sectors. Nonionic polyacrylamide Uses: 1. When the suspended sewage is acidic, it is more appropriate to use non-ionic polyacrylamide as flocculant. This is because PAM acts as an adsorption bridge to make suspended particles flocculate and precipitate, so as to purify the sewage. It can also be used to purify tap water, especially in combination with inorganic flocculants, and has the best effect in water treatment. 2. Adding some chemicals to textile industry auxiliaries can be used to compose chemical data for textile sizing. 3. Dissolve non-ionic polyacrylamide into 0.3% concentration and add crosslinking agent in sand control and sand fixation. Spraying on desert can play a role in sand control and sand fixation. 4. Soil moisturizers are used as basic materials of soil moisturizers and various modified polyacrylamides. Cationic polyacrylamide: Usage: 1. Sludge dewatering can choose the corresponding brand of this product according to the nature of sludge, which can effectively dewatering gravity sludge before the sludge enters the filter press. When dewatering, it produces large flocs, non-sticking filter cloth, non-dispersing, less dosage, high dewatering efficiency and less than 80% moisture content of mud cake. 2. The treatment of sewage and organic wastewater shows positive electricity in acidic or alkaline medium, so flocculation and precipitation of sewage with negative charge of suspended particles in sewage is very effective, such as wastewater from alcohol factory, brewery, monosodium glutamate factory, sugar factory, meat food factory, beverage factory and textile printing and dyeing factory. Cationic polyacrylamide is several or tens of times more effective than anionic polyacrylamide, nonionic polyacrylamide or inorganic salts, because such wastewater generally has negative charges. 3. Water treatment flocculant in Waterworks has the characteristics of low dosage, good effect and low cost. Especially, the combination of inorganic flocculant and inorganic flocculant has better effect. 4. Oilfield chemicals such as clay anti-swelling agents and thickeners for oilfield acidification. 5. Paper reinforcer cationic PAM is a water-soluble cationic polymer containing carbamoyl group. It has the functions of reinforcement, retention and filter aid. It can effectively improve the strength of paper. At the same time, the product is also a highly effective dispersant. Anionic polyacrylamide Uses: 1. Industrial wastewater treatment has the best effect on sewage treatment, such as coarse suspended particles, high concentration, positive charges of particles, neutral or alkaline PH value of water, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. 2. Drinking water treatment in many Waterworks of our country comes from rivers. The content of sediment and minerals is high and turbid. Although it can't meet the requirements after sedimentation and filtration, it needs to add flocculant. The dosage of flocculant is 1/50 of inorganic flocculant, but the effect is several times that of inorganic floc 2、飲用水處理 我國(guó)很多自來(lái)水廠的水源來(lái)自江河，泥沙及礦物質(zhì)含量高，比較渾濁，雖經(jīng)過(guò)沉淀過(guò)濾，仍不能達(dá)到要求，需要投加絮凝劑，投加量是無(wú)機(jī)絮凝劑的1/50，但效果是無(wú)機(jī)絮凝劑的幾倍，對(duì)于機(jī)物污染嚴(yán)重的江河水可采用無(wú)機(jī)絮凝劑和我公司的陽(yáng)離子聚丙烯酰胺配合使用效果更好。 3、淀粉廠及酒精廠的流失淀粉酒糟的回收 現(xiàn)在很多淀粉廠的廢水內(nèi)含淀粉很多，現(xiàn)投加陰離子聚丙烯酰胺，使淀粉微粒絮凝沉淀，然后將沉淀物經(jīng)壓濾機(jī)壓濾變成餅狀，可作飼料，酒精廠的酒精也可采用陰離子聚丙烯酰胺脫水，壓濾進(jìn)行回收。     聚丙烯酰胺用作淀粉廠及酒精廠的流失淀粉及酒糟的回收。往常很多淀粉廠排出的廢水內(nèi)淀粉很高，排放之后影響環(huán)境，糜費(fèi)資源，投加PAM，使淀粉沉淀，沉淀物經(jīng)壓濾機(jī)壓濾變成餅類(lèi)可作飼料，酒精廠大量的酒糟就是采用這種工藝加工的，黑龍江某酒精廠就是聚丙烯酰胺作絮凝劑，對(duì)酒糟中止回收的而且獲得了很大的經(jīng)濟(jì)效益。 聚丙烯酰胺用作油田調(diào)剖堵水的堵水劑，三次采油的驅(qū)油劑。 聚丙烯酰胺用作造紙助劑，PAM在造紙方面用處很普遍，可作為長(zhǎng)纖維造紙分散劑，干濕加強(qiáng)劑，助留，助濾劑及造紙廢水的絮凝劑等。 和協(xié)同效應(yīng)，PAM對(duì)降低外表張力的才干要遠(yuǎn)遠(yuǎn)大于同條件下陽(yáng)離子或陰離子單獨(dú)存在的才干，為抵達(dá)降低外表張力的央求，需求同時(shí)運(yùn)用陰離子和陽(yáng)離子聚丙烯酰胺，便兩者如運(yùn)用不當(dāng)，會(huì)產(chǎn)生白色沉淀物，失去運(yùn)用效果 。而PAM具有兩性離子的特性，它能夠完成陰離子、陽(yáng)離子的配合協(xié)同作用，面沒(méi)有任何沉淀物的產(chǎn)生，特別是對(duì)水質(zhì)狀況比擬復(fù)雜或水的性質(zhì)經(jīng)常變化的，運(yùn)用PAM作為處置絮凝劑更為便當(dāng)，效果更好。 在污水預(yù)處置中采用的污泥取自以錢(qián)塘江水為水源的沉淀池，該水廠以聚合氯化鋁PAC為絮凝劑。污泥經(jīng)自然濃縮到含固率為2.7%～2.8%，經(jīng)測(cè)定，污泥中有機(jī)物含量為12.1%，sj如含量為52.1%，Al。含量為20.2%。 PAM有陽(yáng)離子型、陰離子型和非離子型三品種型。非離子型PAM溶解速度較慢，普通不用于污泥預(yù)處置，因而實(shí)驗(yàn)僅選用兩種有代表性的陽(yáng)離子聚丙烯酰胺和陰離子聚丙烯酰胺。陽(yáng)離子型PAM分子量1200萬(wàn)，丙烯酰胺單體含量0.012%。陰離子型PAM分子量1250萬(wàn)，丙烯酰胺單體含量0.013％。兩種PAM配制濃度均為0.05％%，冰箱冷藏24h后運(yùn)用。 (1)PAM預(yù)處置污泥取lOOml污泥，放入300ml的燒杯中，采用六聯(lián)攪拌機(jī)以1130rpm的轉(zhuǎn)速快 速攪拌30s后疾速投加～定量制備好的PAM，繼續(xù)以lOOrpm的轉(zhuǎn)速攪拌30s， 然后降低攪拌機(jī)轉(zhuǎn)速到20～30rpm慢速攪拌60s促進(jìn)絮凝。分別測(cè)定預(yù)處置后污泥的比阻、毛細(xì)吸水時(shí)間(CST)、過(guò)濾液的粘度和離心液的粘度。 (2)比阻按考克力(Coackley)提出的實(shí)驗(yàn)辦法，采用布氏漏斗實(shí)驗(yàn)。布氏漏斗的直徑為80mm，濾紙采用由70mm定量中速濾紙，實(shí)驗(yàn)真空度控制為0.01MPa。實(shí)驗(yàn)反復(fù)3次取均勻值。 (3)為了降低比阻，進(jìn)步污泥脫水效果，在污泥脫水前普通均需對(duì)污泥中止預(yù)處置。污泥預(yù)處置的辦法有冰凍一凍結(jié)預(yù)處置、熱處置、酸處置、堿處置、石灰預(yù)處置和高分子絮凝劑預(yù)處置等，其中高分子絮凝劑聚丙烯酰胺(PAM) 預(yù)處置是目前國(guó)內(nèi) (4) 聚丙烯酰胺絮凝劑預(yù)處置普通占整個(gè)污泥處置費(fèi)用較高的比例，因而，聚丙烯酰胺的優(yōu)化選投加率的合理肯定對(duì)降低污泥預(yù)處置費(fèi)用相當(dāng)關(guān)鍵。對(duì)選擇聚丙烯酰胺的實(shí)驗(yàn)辦法的研討已展開(kāi)多年，包括比阻、CST值、污泥流變性、分別液粘度、活動(dòng)電流等。The synthesis and process physical properties of AM polyacrylamide: PAM is prepared by direct reaction of acrylonitrile with water under the action of framework copper catalyst, and then dried by ion exchange polymerization. The process is as follows: catalyst: catalytic hydration CH2 = CHCN + H2 humidity CH2 = CHCONH2 polymerization nCH2 = CHCONH2 - initiator - CH2CHCONH2 Industrial uses of polyacrylamide: Polyacrylamide (PAM) has high molecular weight, good water solubility, adjustable molecular weight, and can introduce various ionic groups to obtain specific properties. Low molecular weight is an effective additive or stabilizer for dispersing materials. High molecular weight is an important flocculant. It can produce hydrophilic and water-insoluble gel, which has good adhesion to many groups of surface and dissolved substances. Because of the above properties, PAM is widely used in flocculation, thickening, drag reduction, glue imitation, bonding, scale inhibition and other fields. Anionic polyacrylamide can be used in different molecular weights according to different uses and user's requirements for product performance. In industrial wastewater treatment, especially for suspended particles, coarser, high concentration, positive charged particles, neutral and alkaline wastewater such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater treatment effect is very good. In drinking water treatment. The water source of many Waterworks in our country is low in mud and high in mineral content, which is turbid. Although it has been treated by precipitation, it still can not meet the requirements. Flocculants are needed to make the water quality clear. Many waterworks use inorganic flocculants, but the amount of inorganic flocculants is large, resulting in poor effect of sludge increase. Anionic polyacrylamide acrylamide monomer was 0.012%. The molecular weight of anionic PAM was 12.5 million and the content of acrylamide monomer was 0.013%. The concentration of two kinds of PAM is 0.05%. They are used after refrigeration for 24 hours. (1) PAM pretreatment sludge takes lOml sludge and puts it into a 300 ml beaker. Six-unit mixers are used to mix at 1130 RPM speed for 30 seconds, and then the PAM is added to the sludge quickly and quantitatively. The PAM is stirred at lOOrpm speed for 30 seconds, then the speed of the mixer is reduced to 20-30 rpm and the slow stirring speed is 60 seconds to promote flocculation. The specific resistance of pretreated sludge, capillary water absorption time (CST), the viscosity of filtrate and the viscosity of centrifuge were measured. (2) The specific resistance is tested by Brinell funnel according to the test method proposed by Coackley. The diameter of Brinell funnel is 80 mm. The filter paper is made of 70 mm medium speed filter paper. The vacuum degree of the test is controlled to 0.01 MPa. The experiment was repeated three times to get the average value. (3) In order to reduce specific resistance and improve sludge dewatering effect, sludge should be pretreated before sludge dewatering. Sludge pretreatment methods include freeze-thaw pretreatment, heat treatment, acid treatment, alkali treatment, lime pretreatment and polymer flocculant pretreatment. Polymer flocculant polyacrylamide (PAM) pretreatment is the most widely used pretreatment method at home and abroad. (5)實(shí)驗(yàn)研討標(biāo)明：投加陽(yáng)離子型和陰離子型PAM后污泥比阻都降低近2個(gè)數(shù)量級(jí)，顯著改善了污泥的脫水性能。陰離子型P投加率為0.3kg/T干污泥，陽(yáng)離子聚丙烯酰胺絮凝劑的投加率為1.5kg/T于污泥，可見(jiàn)陰離子型PAM的投加率遠(yuǎn)小于陽(yáng)離子型PAM的投加率，且陰離子型PAM的價(jià)錢(qián)約是陽(yáng)離子型PAM價(jià)錢(qián)的1/2，故陰離子型PAM可作為自來(lái)水廠污泥預(yù)處置藥劑的首選。 (6)依據(jù)CST值變化肯定PA歧。并且CST值與比阻之間存在線(xiàn)性相關(guān)關(guān)系，比阻值越大，CST值越大，因而能夠采用CST值來(lái)近似替代污泥比阻反映污泥的脫水性能。與比阻相比，cST值測(cè)定快速、煩瑣，不但適用于實(shí)驗(yàn)室研討，還可用于消費(fèi)現(xiàn)場(chǎng)，快速理解污泥脫水性能的變化，使操作人員及時(shí)調(diào)楚PAM投加率，儉省藥劑費(fèi)。is used as flocculant, and the dosage is inorganic flocculant. One fiftieth of the flocculants, but the effect is several times to dozens of times that of inorganic flocculants. Especially the polyacrylamide produced by our company, the residual monomers have reached the food grade (less than 0.05%), close to the advanced level abroad, non-toxic, more suitable for the treatment of drinking water, and better for the use of organic pollutants polluted river water and anionic polyacrylamide. Polyacrylamide is used to recover lost starch and distiller's grains in starch and alcohol factories. At present, the starch in the waste water discharged by many starch factories is very high. After discharging, it affects the environment, wastes resources, and adds PAM to make starch precipitate. The precipitate is filtered by pressure filter to become cake and can be used as feed. A large number of distillers'grains in the alcohol factories are processed by this process. A certain alcohol factory in Heilongjiang Province uses polyacrylamide as flocculant, which recycles the distillers' grains and obtains a great deal of experience. Economic benefits. Polyacrylamide is used as water shutoff agent for profile control and water shutoff in Oilfield and oil displacement agent for tertiary oil recovery. Polyacrylamide is used as paper-making additive. PAM is widely used in paper-making. It can be used as long fiber paper-making dispersant, wet and dry reinforcing agent, retention aid, filter aid and flocculant of paper-making wastewater. The latest type of water treatment agent polyacrylamide, when treating sewage and water in many occasions, the combination of anionic polyacrylamide and cationic polyacrylamide has a very significant and synergistic effect than using one kind of ionic polyacrylamide alone. The ability of PAM to reduce surface tension is much greater than the ability of cations or anions existing alone under the same conditions. For the requirement of low surface tension, both anionic and cationic polyacrylamide need to be used at the same time. If they are used improperly, white precipitates will be produced and the effect of using them will be lost. PAM has the characteristics of amphoteric ions. It can complete the coordination of anions and cations. There is no precipitate on the surface. Especially, it is more convenient to use PAM as a flocculant because of the complex water quality or the changeable nature of water. The sludge used in sewage pretreatment is taken from the sedimentation tank with Qiantang River water as its source of water, and PAC is used as a flocculant in the water plant. The sludge was naturally concentrated to a solid content of 2.7%-2.8%. The organic matter content in the sludge was 12.1%, SJ content was 52.1%, Al content was determined. The content was 20.2%. There are three types of PAM: cationic, anionic and nonionic. Non-ionic PAM dissolves slowly and is generally not used for sludge pretreatment. Therefore, only two representative cationic polyacrylamides and anionic polyacrylamides are selected in the experiment. The molecular weight of cationic PAM was 12 million and the content of (7)不管是陽(yáng)離子聚丙烯酰胺絮凝劑還是陰離子聚丙烯酰胺絮凝劑，隨著投加率的增加，濾液和離心液粘度都呈現(xiàn)與比阻和CST值類(lèi)似的變化規(guī)律，呈現(xiàn)了明顯的值對(duì)應(yīng)投加率與污泥投加率根本分歧。該辦法投加率快速、簡(jiǎn)單，而且還有可能用作消費(fèi)上在線(xiàn)控制PAn加率的參數(shù)，但其在消費(fèi)上的應(yīng)用還需做進(jìn)一步的實(shí)驗(yàn)研討。 ent and the command of the party, we basically defeated the epidemic situation. The enterprises returned to work and started to produce polyaluminium chloride polyacrylamide, which basically entered the normal stage. Because our workers are basically the raw materials required by the mature production technology of local employees, and also the polyacrylamide that can be purchased in the province As a necessary medicine for sewage treatment, polyaluminium chloride is indispensable in every industry of every enterprise, but the impact is not on our internal production, but on the external production of many small enterprises, which can not use the most sand washing food sewage plants, sewage plants, which can not stop, the most impact is that small manufacturers, we have a strong production force to settle down With the support of capital support and old customers, the daily shipment volume is more than 100 tons, and the price is also provided to customers with the support of the government's tax-free and rent-free stimulus economy to help small and medium-sized enterprises through difficulties, with high quality and low price and stable market sentiment Henan anjiajing environmental protection polyacrylamide polyaluminium chloride polyferric sulfate selection we choose one service, one integrity, one moving, one stable and looking forward to your call manager of anjiajing environmental protection Cao 15838356978 聚合氯化鋁PAC處理后的水鋁含量很低，這也是目前PAC在飲用水處理的主要因素之一。此外，優(yōu)質(zhì)飲用水級(jí)PAC使處理后的水更加安全。聚合氯化鋁g to the actual object. The technology will compose 0.1-0.5% solution, and then determine the project dosage in a small scale. Four-thousandths of the 1,200-15 million parts of polyacrylamide wastewater treatment will be compounded with 7-10 grams of monosodium glutamate per ton, layer slag of brewery, wastewater and so on. We can see from the above, in addition to the help of manufacturers to choose polyacrylamide, when using their own, we should pay attention to the use of polyacrylamide. Let's simply remember the following points. Dissolution equipment is required. Concentration should not exceed five thousandths when dissolving. If the equipment is a very simple dissolving pot, we should pay attention to adding 20% of the volume of water in the tank first, then polyacrylamide and water into the tank at the same time, and polyacrylamide should be poured into the tank at a uniform speed, not too much at one time. Otherwise, fish eyes and other phenomena will occur. 我們的回答只是個(gè)大概和預(yù)算，具體多少還 是要根據(jù)具體的實(shí)物來(lái)測(cè)算。技術(shù)會(huì)配成0.1~0.5%溶液，然后小試確定工程用量，聚丙烯酰胺的污水處理1200-1500萬(wàn)千分之四配每噸用7-10克味精、啤酒廠 層渣、廢水等。我們從上面看出，除了廠家?guī)兔x購(gòu)聚丙烯酰胺，自己在使用時(shí)候，要注意聚丙烯酰胺的使用方法。我們只要簡(jiǎn)單的記住以 下幾點(diǎn)。要有溶藥設(shè)備。在溶解的時(shí)候濃度設(shè)定不要超過(guò)千分之五。如果設(shè)備是很簡(jiǎn)易的溶藥罐的話(huà)，要注意在人工加藥時(shí)，要先加20%罐體積的水，然后聚丙烯酰胺和水同時(shí)進(jìn)罐，并且聚丙烯酰胺要?jiǎng)蛩俚南蚶锩鎯A倒，不要一次性加的太多。否則會(huì)產(chǎn)生魚(yú)眼等現(xiàn)象 |
