通过对江汉油田含油污水所进行的水处理剂综合评选实验,评选出了聚丙烯酰胺等3种絮凝剂、1种助絮凝剂、4种防垢缓蚀剂和2种杀菌剂以及较佳的净水条件,同时还得出了各种处理剂的加入顺序,经用综合评选出来的配方处理含油污水,其除油率达到100%,除铁率达到97.4%,除机械杂质达到97%,且溶解氧(DO),硫酸盐还原菌(SRB)、腐生菌(TGB)和结垢率均达到了部颁《注入水水质标准》,实验研究还为清污混注提供了有用的数据,证明各药剂配伍性很好。
Through the comprehensive selection test of water treatment agent for oily wastewater in Jianghan Oilfield, three kinds of flocculants such as polyacrylamide, one kind of flocculant, one type of scale inhibitor and two kinds of bactericides and the best Water purification conditions, but also come to the order of addition of various treatment agents, the formula selected by the comprehensive treatment of oily wastewater, the oil removal rate reached 100%, iron removal rate reached 97.4%, except for mechanical impurities reached 97% DO, SRB, TGB, and fouling rates all reached the ministerial criteria for quality of injected water, and experimental data provided useful data for clarification mixing The compatibility of the drug is very good.
