化工废水处理技术研究进展
|
摘要
近年来,随着人们环保意识不断的增强,废水的排放标准也越来越高。化工废水排放量大,污染物的种类繁多,结构复杂,浓度高难降解,对我国水环境安全问题带来了巨大的威胁。本文结合我国化工废水的主要来源、水质特征和危害,重点介绍了目前国内处理化工废水的主要技术,包括物理法、化学法、生物法,以及多种方法的组合应用。在比较各种技术优缺点的基础上,提出了处理化工废水的方法。
In recent years,with the increasing awareness of environmental protection,the discharge standard of wastewater is getting higher and higher. The chemical wastewater discharge is large,the kinds of pollutants are various,the structure is complex,the concentration has difficult degradation,which poses a great threat to the water environmental security in our country. Based on the main sources,water quality characteristics and hazards of chemical wastewater in China,the main technologies of domestic chemical wastewater treatment were introduced,including physical method,chemical method,biological method and combined application of various methods. On the basis of comparison of advantages and disadvantages of various technologies,a method for treatment of chemical wastewater was proposed.
