工业废水分类
通常有以下三种:
Usually there are three kinds:
第一种是按工业废水中所含主要污染物的化学性质分类，含无机污染物为主的为无机废水，含有机污染物为主的为有机废水。例如电镀废水和矿物加工过程的废水是无机废水，食品或石油加工过程的废水是有机废水，印染行业生产过程中的是混合废水，不同的行业排除的废水含有的成分不一样。
The first one is classified according to the chemical properties of the main pollutants in industrial wastewater. The inorganic pollutants are mainly inorganic wastewater and the organic pollutants are mainly organic wastewater. For example, electroplating wastewater and mineral processing wastewater are inorganic wastewater, food or petroleum processing wastewater is organic wastewater, printing and dyeing industry production process is mixed wastewater, different industries excluded wastewater contains different components.
第二种是按工业企业的产品和加工对象分类，如冶金废水、造纸废水、炼焦煤气废水、金属酸洗废水、化学肥料废水、纺织印染废水、染料废水、制革废水、农药废水、电站废水等。
The second is classified according to the products and processing objects of industrial enterprises, such as metallurgical wastewater, paper-making wastewater, coking gas wastewater, metal pickling wastewater, chemical fertilizer wastewater, textile printing and dyeing wastewater, dyeing wastewater, tannery wastewater, pesticide wastewater, power station wastewater, etc.
第三种是按废水中所含污染物的主要成分分类，如酸性废水、碱性废水、含氰废水、含铬废水、含镉废水、含汞废水、含酚废水、含醛废水、含油废水、含硫废水、含有机磷废水和放射性废水等。
The third is classified according to the main components of pollutants in wastewater, such as acid wastewater, alkaline wastewater, cyanide wastewater, chromium wastewater, cadmium wastewater, mercury wastewater, phenol wastewater, aldehyde wastewater, oil wastewater, sulfur wastewater, organophosphorus wastewater and radioactive wastewater.
前两种分类法不涉及废水中所含污染物的主要成分，也不能表明废水的危害性。
The first two classification methods do not involve the main components of pollutants in wastewater, nor can they indicate the harmfulness of wastewater.
