百色、陆良盆地石油钻井污水处理

Treatment of petroleum drilling waste water in Baise and Luliang basins

研究了水生植物法、水生植物一化学絮凝法、化学絮凝法、化学沉降法对钻井污水进行的处理，并着重研究了化学絮凝法。通过室内和现场试验应用表明，百色、陆良盆地石油钻井污水采用氯化钙十石灰十铝盐进行三级处理后，可取得满意效果，并有推广应用价值。

Drilling waste water is researched and treated by hydrophyte, hydrophyte-chemical coagulation, chemical coagulation and chemical subsidence, of whichchemical coagulation is emphasized. After the drilling waste water in Baise and Luliangbasins are treated by three steps with calcium chloride, lime and aluminum salt respectively, indoors and field experiments demonstrate that the result is satisfactory and thismethod is recommended to be extended.
