摘　　要：文章研究了低温低浊水混凝剂及助凝剂的优化选择,考察了浊度、COD M n、氨氮等水质特征,分析了低温低浊水的处理效果。结果表明,混凝剂和助凝剂投加量增大,上清液中浊度、COD去除率不断提高。在PAFC用量为12 mg/L,活化硅酸用量为0.12 mg/L条件下,浊度、COD去除率分别达到最大值98.3%和87%,剩余浊度和剩余COD M n分别为0.21 NTU、0.64 mg/L。而PAC+PAM表现出更好的除氨氮效果,剩余氨氮为0.07 mg/L。In this paper the treatment of the water with lowtemperature and lowturbidity by selected coagulants and coagulant aids was studied,along with such water qualities as turbidity,COD M n,ammonia nitrogen investigated and the lowtemperature and lowwater treatment effect analyzed. The results showthat as the dosage of coagulants and coagulant aids increases,supernatant turbidity,COD M n removal rate increase. In the amount of PAFC 12 mg / L and activated silicic acid 0. 12 mg / L,the removal rate of turbidity,COD M n reaches a maximum of 98. 3% and 87%. Residual turbidity and residual COD were 0. 21 NTU,0. 64 mg / L. The PAC＋ PAM showed a better effect in addition to ammonia. Residual ammonia was 0. 07 mg / L.
