摘　　要：采用化学絮凝法在不同条件下对冲灰水中悬浮物的去除效果进行了研究。实验结果表明,用聚合氯化铝作为絮凝剂处理冲灰水样效果较聚合氯化铁好,当聚合氯化铝投加质量浓度为1 400 mg/L,pH值为7.9,搅拌强度为快速搅拌180 r/min、慢速搅拌40 r/min时悬浮物的去除效果最好,悬浮物去除率可达到99%以上。The suspended solid in ash sluicing water was removed by chemical flocculation process,and its removal efficiency was studied.The experimental results showed that the removal efficiency of SS could reach to more than 99% under the following conditions that the dosage of PAC was 1 400 mg/L,pH was about 7.9,and the quick stirring rate was 180 r/min and slow stirring rate was 40 r/min.
