摘　　要：电镀表面处理工艺较为复杂,生产用水量和排水量较大,属于污染型生产企业。生产过程中排放的废水中主要含CN-、有机污染物、Ni2+、Cu2+、酸、碱等污染成份。其中重金属Ni2+等属于第一类污染物,需经预处理。要求第一类污染物在电镀车间排口达标后再与其他有机综合废水混合,处理达标。根据国家和地方节能减排要求,废水处理达标后要求60%回用于生产。It is more complex that plating surface treatment process in metal processing plant. It needs much more production water and wastewater amount is larger,so metal processing plant belongs to the type of pollution production enterprises. There are CN-,organic pollutants,Ni2 +,Cu2 +,acid,alkali and other pollution elements in wastewater. The heavy metal Ni2 +belongs to the first class pollutants,it needs pretreatment. The first class of pollutant in electroplating workshop must be treated in advance,and then mixed with other organic wastewater,treated again to reach the effluent standard. According to the requirements of the national and local energy-saving effluent reduction,60% treated wastewater must be reused in production.
