摘要
通过小试与生产试验对比了传统化学除磷药剂聚合氯化铝(PAC)与新型复配药剂益维磷对污水中总磷的去除效果。结果表明,益维磷在生物安全性与除磷效果上均优于PAC。一方面,益维磷对氧化沟污泥不产生任何不利影响;另一方面,当进水总磷高达3.7~3.8 mg/L时,投加23 mg/L的益维磷即可保持污水厂出水总磷低于1.0 mg/L。
A traditional phosphorus removal agent polyaluminium chloride （PAC） and a novel compound reagent named EnvironLeen were investigated in lab test and production test. The results showed that EnvironLeen had a huge advantage over PAC in both the biosecurity and the phosphorus removal rate. EnvironLeen had no adverse effect towards the activated sludge system. In addition, a dosage of 23 mg/L EnvironLeen could maintain the phosphorus concentration in effluent below 1.0 mg/L when the influent concentration was 3.7 - 3.8 mg/L.
