工業(yè)廢水是在工礦生產(chǎn)活動(dòng)中產(chǎn)生的廢水。工業(yè)廢水可分為生產(chǎn)污水與生產(chǎn)廢水。生產(chǎn)污水是指在生產(chǎn)過程中形成、并被生產(chǎn)原料、半成品或成品等原料所污染，也包括熱污染（指生產(chǎn)過程中產(chǎn)生的、水溫超過60℃的水）；生產(chǎn)廢水是指在生產(chǎn)過程中形成，但未直接參與生產(chǎn)工藝、未被生產(chǎn)原料、半成品或成品等原料所污染或只是溫度少有上升的水。生產(chǎn)污水需要進(jìn)行凈化處理；生產(chǎn)廢水不需要凈化處理或僅需做簡(jiǎn)單的處理，

人類生產(chǎn)活動(dòng)造成的水體污染中，工業(yè)引起的水體污染最嚴(yán)重。如工業(yè)廢水，它含污染物多，成分復(fù)雜，不僅在水中不易凈化，而且處理也比較困難。

廣州地區(qū)含酚工業(yè)廢水處理工程

含酚廢水主要來自焦化廠、煤氣廠，石油化工廠，絕緣材料廠等工業(yè)部門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)藥和酚醛樹脂生產(chǎn)過程。

  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，魚類就會(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，稱為低濃度含酚廢水。通常將這類廢水循環(huán)使用，將酚濃縮回收后處理�；厥辗拥姆椒ㄓ腥莘e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。

Industrial wastewater is a waste water produced in the industrial and mining activities. Industrial wastewater can be divided into production sewage and production wastewater. Production sewage refers to the production process of formation, and is the production of raw materials, pollution of semi-finished or finished products and other raw materials, including thermal pollution (refers to water generated in the production process, more than 60 DEG water); production wastewater is formed in the process of production, but is not directly involved in the production process, production is not raw materials, semi-finished products or finished products and other raw materials contaminated or just little water temperature rise. The production sewage needs to be cleaned and treated; the production wastewater does not need to be cleaned or simply treated, such as cooling treatment. The mixed sewage from domestic sewage and production sewage is called urban sewage.

In the water pollution caused by human production activities, the water pollution caused by industry is the most serious. Such as industrial wastewater, it contains more pollutants and complex components, not only in water is not easy to purify, but also difficult to deal with.

Treatment engineering of Phenol Industrial Wastewater

Phenolic wastewater mainly comes from coking plant, gas plant, petrochemical plant, insulating material factory and other industrial sectors, and petroleum cracking production to ethylene, synthetic phenol, polyamide fiber, synthetic dyes, organic pesticides and phenolic resin production process.

Phenolic compounds are mainly contained in waste water containing phenol, such as phenol, cresol, two cresol and nitrocresol. A phenolic compound is a protoplast poison that can solidify the protein. The mass of phenol in the water reaches 0.1~0.2mg/L, and the fish will die. Drinking water containing phenol can affect the health of the human body. Even if the concentration of phenol in the water is only 0.002mg/L, chlorophenol can also produce the odour of chlorophenol.

The phenolic wastewater with a mass concentration of 1000mg/L is usually called high concentration phenol wastewater, which must be recycled and then treated.  Phenol wastewater with a mass concentration less than 1000mg/L is called low concentration phenol wastewater. This kind of waste water is usually recycled, and the phenol is concentrated and retreated. The methods for recovery of phenol include volume extraction, steam stripping, adsorption and closed cycle. The wastewater with the concentration of phenol under 300mg/L can be recovered by biological oxidation, chemical oxidation, physical oxidation and other methods.
