摘要
现代工业生产中,会产生大量含有多种重金属元素、化学成分的废水,此类废水如未能得到妥善处理,一旦排放到自然环境中会造成严重的生态污染。化学工艺是废水处理的主要方式之一,应遵循工业废水处理的七项基本原则,合理利用现有条件,保障废水分离的严格性,按照废水种类制定相应的处理措施。当前采用化学工艺处理废水的主要方法有化学热力理论法、化学混凝法、化学中和氧化法、A/O(厌氧-好氧)法等,均取得了较为显著的作用。
In modern industrial production,a large number of wastewater containing a variety of heavy metal elements and chemical components will be produced.If such wastewater is not properly treated,it will cause serious ecological pollution once discharged into the natural environment.Chemical process is one of the main ways of wastewater treatment.It should follow the seven basic principles of industrial wastewater treatment,make rational use of the existing conditions,ensure the strictness of wastewater separation,and formulate corresponding treatment measures according to the types of wastewater.At present,the main methods of treating wastewater by chemical process have all played great role include chemical thermodynamic theory method,chemical coagulation method,chemical neutralization oxidation method,A/O(anaerobic aerobic)method and so on.
