摘　　要：采用新型混凝剂聚磷氯化铝铁(PPAFC)对含铬废水进行混凝处理;再采用铝化改性膨润土对含铬废水进行吸附处理。结果表明:在PPAFC 40mg/L,铝化改性膨润土2.0g/L,室温的条件下,总铬的去除率超过99.8%,出水中总铬的质量浓度达到《电镀污染物排放标准》(GB 21900-2008)要求。Polymeric phosphate-aluminum ferric chloride（PPAFC） flocculent was used to perform a coagulation treatment on wastewater containing chromium,and then Al-modified bentonite was used to conduct a adsorption treatment on the wastewater containing chromium.The results show that the removal ratio of total chromium can exceed 99.8 % when PPAFC is 40 mg/L,Al-modified bentonite 2.0 g/L,room temperature.The mass concentration of total chromium in the discharged water meets the Electroplating Pollutant Discharge Standards（GB 21900-2008）.
