  • 摘要: 将“混凝沉淀-前置砂滤池-升流式生物活性炭滤池”工艺出水分别进入后砂滤池与超滤膜组件，比较两者对水中的浊度、CODMn、氨氮、颗粒数及微型生物的去除效果。结果表明：超滤膜平均去浊率为31.57%，去浊优势不是很明显，但明显高于后砂滤池去浊率；对于CODMn的去除，后砂滤池的平均去除率为6.80%，优于超滤膜；后砂滤池对氨氮的去除率达到50.08%，相比超滤膜优势很明显；超滤膜出水颗粒数相对较平稳，且能有效保证饮用水生物安全性。后砂滤池的微絮凝作用，可使其出水浊度、CODMn及微型生物数量均有所降低，但其对微型生物的去除效果与超滤膜相比仍有不足。
    Abstract: The effluent from a coagulation sand-filter upflow biological activated carbon filter process was treated by a rear-set sand filter and an ultrafiltration (UF) membrane module.This paper compares the removal effect of the two techniques on turbidity,CODMn,ammonia nitrogen,particle numbers,and microorganisms.Experimental results showed that the average removal rate of turbidity by UF was 31.57%,which is not a high proportion,but it was significantly higher than that by the rear-set sand filter.For the removal of CODMn,the average removal rate by the sand filter was 6.80% higher than that by UF.The removal rate of ammonia nitrogen by the sand filter was 50.08%,which was higher than that by UF.The particles of the effluent from the UF membrane were relatively stable,therefore UF effectively ensured the biological safety of drinking water.The microflocculation of the rear-set sand filter decreased the turbidity,CODMn,and microbial quantities,but when compared with the UF membrane,the removal effect of microorganisms was still insufficient.
