| 摘 要： | 研究采用活化沸石曝气生物滤池(AZBAF)预处理微污染原水,考察其在低温下(7.8～16.2℃)的运行特性。结果表明,水力负荷和气水比对CODMn去除的影响较大,而对NH3-N的去除影响甚微。在水力负荷0.8 m3/(m2.h)、气水体积比1:1的优化工艺条件下,AZBAF对CODMn、NH3-N和藻类的平均去除率分别为47.1%、91.9%、42.4%。反冲洗后滤池内生物量减少,生物活性提高,在3 h后即可恢复正常运行。

| Abstract: | In this study,AZBAF was employed for pretreating micro-polluted source water,in order to examine the process characteristics at low temperature of 7.8~16.2 ℃.The results indicated that CODMnremoval was influenced much by the variation of hydraulic loading and air-water ratio,as compared to that of NH3-N.Under the optimum conditions of hydraulic loading 0.8 m3/(m2.h) and air-water volume ratio 1:1,the average removal efficiencies of CODMn,NH3-N and alga were around 47.1%,91.9% and 42.4%,respectively.After the backwashing operation,biomass was decreased in the AZBAF whereas an increase was found in the biological activity,and the biofilter could recover to the original level in 3 h. |
