化工废水治理研究及应用现状

Research and application of chemical wastewater treatment

化工产业规模的扩大需要充足的水资源,所排放的大量化工废水对环境的污染程度也随之增加。化工废水水质成分繁杂、污染物占比高、治理难度大,如不采取科学的治理手段,不仅影响生态环境,甚至危及人类的生命健康。随着针对生态保护力度的逐渐加强,化工废水的处理方式在完善进步,以减少废水对环境的污染。文中介绍了化工废水的特征和危害,重点论述了3种典型化工废水的治理方法和应用现状。

The chemical industryexpansion needs plenty of water resources,which increases the environment pollution by dischargedchemical wastewater.Chemical wastewater with the characteristic of complexcomposition,highproportion of pollutants,will not only affect the ecological environment,and even endanger human life and health if no scientific action is taken.With the gradual strengthening of ecological protection,the treatment of chemical wastewater is improving to reduce the environmentpollution by wastewater.This paperintroducedthe characteristics and hazards of chemical wastewater and emphatically discussedthe treatment methods and application status of three typical chemical wastewater.
