苏南S市地表水生物预处理试验研究

Experimental Research of Biological Pretreatment of Groundwater of S City in Jiangsu

以我国苏南S市地表河流作为试验用原水,研究了以无机固体活性填料为滤料的生物滤池对该原水进行生物预处理的实际运行情况。研究结果表明:生物滤池可以明显改善原水水质。对于试验原水而言,对CODMn的平均去除率33．4％。对NH3-N的平均去除率则可以达到86．9％,出水浊度、藻类也得到一定程度的降低。

Bio-filter using inorganic solid activated media to purify raw water was studied. The raw water was taken from a river in S city of Jiangsu. It was shown the bio-filter could obviously improve the raw water quality. As far as the raw water in this study was concerned, the average removal efficiency of CODMn, NH3-N in the bio-filter was 33.4%,86.9%, respectively. Turbidity and algae were decreased to a certain degree.
