摘要
进行了生物滤池系统在低温下对官厅水库入库水生物预处理可行性研究。在水温 1 0℃时水力负荷的提高对氨氮的去除效果影响很小 ,但水温为 5℃ (或低于 5℃ )时水力负荷的提高会导致氨氮的去除效果的明显下降。总体说来 ,生物滤池系统在低温条件下对有机物 (高锰酸盐指数 )
A feasibility study was conducted for treating Guanting Reservoir inflow by using bio-filters. The study showed that an increase of hydraulic loading did scarcely affect the removal efficiency of ammonium at the water temperature of 10℃, but was detrimental to the removal efficiency at the water temperature of 5℃ and below. In general, bio-filters showed effective removal of organic carbons in terms of permanganate index.
