摘　　要：以铁盐为絮凝剂 ,对上海合流一期污水处理进行了试验研究 ,结果表明 :当铁盐投加量为 2 0mg/L(以Fe3 +计 )时 ,COD、BOD5 的去除率分别达 48%、6 2 %,TP去除率为 74%～ 86 %,SS去除率为 70 %左右 ,铁盐实际投加量与理论需求量的摩尔比为 4.8。当铁盐与高分子助凝剂复配使用时 ,铁盐的投加量可相应减少。A study on treatment of Shanghai first phase combined wastewater with iron salt was carried out. The results showed that when dosage of metal ion Fe 3+ was 20 mg/L, the removal of COD was 48%, BOD 5 was 62%, total phosphorus was 74%～86% and SS was about 70%. The molar ratio of practical dosage to theoretical demand was 4.8. The dosage of iron salt could be reduced with the aid of polymer.
