Abstract:
The COD removal of the discharged wastewater of the oi-l field wastewater by bio-flocculant is studied further.The experimental results show that ( 1) CODCr concentration is reduced to 134 mg??L from 297 mg??L and the operation costs ??0.7??m3 wastewater under the conditions of pH 5.5 and bio-flocculant in concentration 200 mg??L;( 2) The performance of the bio-flocculant in treating the discharged wastewater of oi-l field is better than that of polyaluminium chloride or polyacrylamide.

摘要：
对生物絮凝剂去除油田外排水CODCr进行了较深入的研究。现场试验结果表明:(1)在pH值为5。5和投加量为200mgL生物絮凝剂的条件下，可使油田废水的CODCr由297mgL降到134mgL，药剂费约为0。7元m3;(2)该生物絮凝剂在处理油田外排水方面的性能优于聚合氯化铝和聚丙烯酰胺。
