摘　　要：通过研究5种无机、有机絮凝剂对电镀废水的处理效果,确定了能有效除去铬的复合絮凝剂的复配比和复配关系。复合絮凝法具有沉淀污泥少、絮凝颗粒大、沉降速度快等特点,当以最佳量投加时,滤液无色。铬的除去率达到99.99%。This paper studied five inorganic or organic flocculents for the electroplating chromium wastewater treatment. We get the suitable complex flocculent and dosage of it. This method has the advantages of less sludge, large flocculation particle and rapid precipitating velocity. After the treatment with complex flocculent in the best way, the liquid is colorless ,and the removal rate of Cr is 99. 99%.
