查询词典 waste water

PCBs at the beginning of the land fill were mainly composed of the 3-Cl and 5-Cl compounds. In the late of the land fill, 2-Cl compounds increased significantly. The main factor affecting the PAHs, PCBs contents were microbial degradation and transformation. Analysis of the pollutants source s indicated that PAHs in sludge were mainly derived from the waste water of refinery, coking plant, gasworks, smelt plant and pitch plant.

填埋初期污泥中PCBs主要以3-Cl和5-Cl化合物为主，填埋后期，2-Cl化合物大大增加，占总的PCBs含量的大部分影响PAHs、PCBs含量变化的主要因素是生物对PAHS的降解转化根据污泥中各污染物的含量对污染物进行源解析表明，污泥中PAHs主要来源于炼油厂、炼焦厂、煤气厂、冶炼厂和沥青厂等排放的废水。
