摘　　要：研究采用了无机絮凝剂聚合硫酸铁(PFS)联合微波诱导氧化工艺,考察絮凝剂用量、敏化剂用量、微波时间、微波功率对焦化废水CODCr、色度去除效果的影响,并通过稳定性实验考查该联合工艺的稳定性。结果表明,在絮凝剂投加量为800 mg/L,敏化剂用量为10 g/L,微波功率为900 W,辐射时间为6 min的条件下,对焦化废水CODCr、色度去除率分别为96.6%、96.4%,CODCr达到了《炼焦化学工业污染物排放标准》(GB 16171—2012)的直接排放标准,联合工艺出水稳定。The process of the inorganic flocculant polyferric sulfate （PFS） combined with microwave induced oxidation process is studied in this paper. The effects of llocculant dosage, sensitizer dosage, and microwave irradiation time and microwave power on the CODer and chroma removal in coifing wastewater are inspected in detail and the stability of this integration process is also tested. The results show that when dosage of PFS and sensitizer is 800 mg/L and 10 g/L respectively and microwave power is 900 W, CODcr and chroma removal rates are 96.6% and 96.4% respectively with 6mira of irradiation time. The remaining contents of CODcr can meet the requirements of ＂Emission Standard of Pollutants for Coking Chemical Industry＂ （GB 16171--2012） and the effluent of process integration has good stability.
