摘要
焦化废水通过常规溶剂脱酚、生物脱酚净化处理后，常常难以达到国家允许的排放标准。通过模拟试验研究，确定了絮凝剂及最佳投放量。应用于生产外排废水的再净化后，ＣＯＤ的净化率提高了３５．７％；氰化物的净化率提高了５７．７％。
The coking effluent often can not reach the national discharging standard although it has been purified by the conventional solvent dephenolizing and biological dephenolizing.The flocculent and the optimum adding quantity are selected after lots of simulation tests.Its application makes the COD purification efficiency up 35.7% and the CN purification efficiency up 57.7% in coking effluent repurification.
