| 摘 要： | 针对西北村镇集雨窖水含浊低温微污染的水质特点,采用粉末活性炭(PAC)强化PAFC混凝处理。考察了粉末活性炭对有机物的去除效果并将其与混凝剂PAFC单独投加进行对比,研究其强化混凝效果。试验结果表明:在PAFC的最佳投加量为60 mg/L,混合搅拌强度300 r/min,搅拌0.5 min,絮凝搅拌强度100 r/min,絮凝10 min,静沉15 min的条件下,活性炭在投加混凝剂后3 min投加,投加量为10 mg/L时,浊度和COD_(Mn)的去除率比常规混凝提高10%和8.8%,具有明显的增强混凝效果的作用。

| Abstract: | Based on the turbidity.lower tempreature and micropolluted of cellar water in towns, the use of activated carbon was used to enhance the coagulation with PAFC, the results show： under the condtiou PAFC dosage of 60 mg/L, the mixed-stirring rate of 300 r/min, the stirring time of 0.5 min,the flocculation-stirring rate of 100 r/min, the stirring time of 10 min, the settling time of 15 min, by activated carbon dosage in 3 min after adding coagulant, the removal rate of turbidity and CODMn are increased 10 % and 8.8 % by compared with conventional coagulation. |
