生物慢滤对污染物的去除效果研究

Study on Removal Efficiency of Slow Biofiltration for Pollutants

生物慢滤作为预处理可以充分发挥微生物的生物降解作用,初步去除原水中的有机污染物及氮、磷等无机污染物。研究了生物慢滤作为预处理措施处理微污染原水的效果。结果表明,生物慢滤对于去除水中浊度、CODMn、NH4+-N、TN、TP有很好的处理效果,平均去除率分别达到92.3%、34.5%、90.2%、45.2%、30.6%。

Slow biofiltration plays an important role in biodegradation as pretreatment measure,and it can remove the pollutants such as organic matter,nitrogen,phosphorus and other inorganic pollutants in source water.This paper focused on the removal efficiency of slow biofiltration as pretreatment measure to process the micro-polluted source water.The results showed that slow biofiltration had good removal efficiency for turbidity,CODMn,NH＋4-N,TN and TP,and the average removal rate reached 92.3%,34.5%,90.2%,45.2%,30.6%,respectively.
