摘要
杭州玻璃总厂的受污染水源经过厌氧-缺氧-好氧预处理后,再经混凝沉淀、过滤,COD值由30～90mg/L降为10～25mg/L,去除率为67～73%,达到Ⅳ类水体标准.浑浊度由35～90度降为0.5～3度,达到自来水标准.对氨氮去除亦有一定的作用,进水氨氮为0.85mg/L,好氧池氨氮为0.25mg/L,去除率为70%.
The raw water source of Hangzhou Glass Factory in Zhejiang province has been polluted. As a result of bio-pretreatment consisted of aerobic-anaerobic process, coagulating sedimentation and filtration the COD decreases form 30-90 mg/l to 10-25 mg/1 with removal rate of 67-73% to meet the standard of IV category of water body. The turbidity of raw water decreases from 35-90 degree to 0. 5 - 3 to meet the requirement of urban water supply. Also the ammonia nitrogen content in raw water decreases from 0. 8 mg/l to 0. 25 mg/l in the aerobic tank with removal rate 70%.
