水處理是指為使水質(zhì)達(dá)到一定使用標(biāo)準(zhǔn)而采取的物理、化學(xué)措施。飲用水的最低標(biāo)準(zhǔn)由環(huán)保部門(mén)制定。工業(yè)用水有自己的要求。水的溫度、顏色、透明度、氣味、味道等物理特性是判斷水質(zhì)好壞的基本標(biāo)準(zhǔn)。水的化學(xué)特性，如其酸堿度、所溶解的固體物濃度和氧氣含量等，也是判斷水質(zhì)的重要標(biāo)準(zhǔn)。

含酚工業(yè)廢水處理工程

含酚廢水主要來(lái)自焦化廠、煤氣廠，石油化工廠，絕緣材料廠等工業(yè)部門(mén)以及石油裂解制乙烯、合成苯酚、聚酰胺纖維、合成染料、有機(jī)農(nóng)藥和酚醛樹(shù)脂生產(chǎn)過(guò)程。

  含酚廢水中主要含有酚基化合物，如苯酚、甲酚、二甲酚和硝基甲酚等。酚基化合物是一種原生質(zhì)毒物，可使蛋白質(zhì)凝固。水中酚的質(zhì)量濃度達(dá)到0.1~0.2mg/L，魚(yú)類(lèi)就會(huì)大量死亡。飲用水中含酚能影響人體健康，即使水中含酚質(zhì)量濃度只有0.002mg/L，用氯消毒也會(huì)產(chǎn)生氯酚惡臭。

  通常將質(zhì)量濃度為1000mg/L的含酚廢水，稱(chēng)為高濃度含酚廢水，這種廢水須回收酚后再進(jìn)行處理。質(zhì)量濃度小于1000mg/L的含酚廢水，稱(chēng)為低濃度含酚廢水。通常將這類(lèi)廢水循環(huán)使用，將酚濃縮回收后處理。回收酚的方法有容積萃取法、蒸汽吹脫法、吸附法、封閉循環(huán)法等。含酚質(zhì)量濃度在300mg/L以下的廢水可用生物氧化、化學(xué)氧化、物理氧化等方法進(jìn)行處理后排放回收。

濟(jì)寧天通設(shè)備有限公司是一家從事水處理設(shè)備生產(chǎn)、銷(xiāo)售集一體化的企業(yè)，經(jīng)過(guò)不斷的努力在國(guó)內(nèi)外獲得了供不應(yīng)求的大好市場(chǎng)，贏得了客戶(hù)的一致好評(píng)。

多年的發(fā)展歷程，公司始終堅(jiān)持創(chuàng)新、品質(zhì)、服務(wù)、敬業(yè)、感恩的理念。采納新創(chuàng)意，嚴(yán)格質(zhì)量，全方位的服務(wù)跟蹤，堅(jiān)持做出高品質(zhì)產(chǎn)品。

Water treatment refers to the physical and chemical measures taken to achieve a certain standard of water quality. The minimum standards for drinking water are made by environmental authorities. Industrial water has its own requirements. Water temperature, color, transparency, smell, taste and other physical properties are the basic criteria to judge water quality. The chemical properties of water, such as its acidity, the concentration of dissolved solids and oxygen content, are also important criteria for judging water quality.

Phenol industrial wastewater treatment project

Main wastewater containing phenol from coking plant, coal gas, petroleum chemical plant, insulation materials plant and other industrial departments and pyrolysis, synthetic phenol oil, polyamide fiber, synthetic dyes, organic pesticides and phenolic resin production process.

Phenolic compounds, such as phenol, cresol, dimethylphenol and nitrocresol, are the main compounds in phenol wastewater. Phenolic compound is a kind of protoplasm, which can solidify protein. The concentration of phenol in water reaches 0.1~ 0.2mg/L, and the fish will die a lot. The phenol in drinking water can affect human health, even if the concentration of phenol in water is only 0.002 mg/L, chlorine disinfection can produce chlorophenol stench.

The quality concentration is usually 1000mg/L of phenol wastewater, which is called high concentration of phenol wastewater, which must be recovered and processed. The quality concentration is less than 1000mg/L of phenol wastewater, which is called low concentration phenol wastewater. This kind of waste water is usually recycled, and the phenol concentration is recycled. The method of recovering phenol has the volume extraction method, steam blowing off method, adsorption method, closed circulation method and so on. The concentration of phenol in the waste water below 300mg/L can be treated with biological oxidation, chemical oxidation, physical oxidation and other methods.
