摘　　要：在中南部某高浓度含铬废水污水处理站原有化学处理工艺基础上,通过小试和生产实践研究了絮凝剂优选和尾水p H值调节,提高了六价铬和总铬的去除率,保证出水各项指标稳定达标,同时还改善了出水观感,降低了产泥率。Chemical reduction is the most commonly used method for the treatment of high concentration chromium containing wastewater.Based on the original chemical treatment process of a high concentration chromium wastewater treatment station in the south central part of China,the optimization of flocculant and pH value regulation of tail water was studied through small-scale test and production practice.The removal rate of hexavalent chromium and total chromium is improved,the stability of effluent indicators ensured,the appearance of effluent improved,and the sludge production rate reduced.

关 键 词：化学还原法 絮凝沉淀 色度 产泥率 pH值
