摘要
利用在线浊度仪和颗粒计数仪监测生物活性炭(BAC)滤池进出水水质,结果表明经单独水反冲洗的BAC滤池,达到浑浊度和颗粒物的稳定去除需要2～3h。在过滤成熟期内BAC滤池对浑浊度和颗粒物有进一步的去除,浑浊度去除率为10%～30%,颗粒物去除率为15%～60%。初滤水的浑浊度和颗粒数明显高于正常过滤,颗粒数与异养菌数量有较好的相关性,表明颗粒物上可以附着大量的异养菌,是BAC滤池出水异养菌平板计数(HPC)结果升高的一个影响因素。
Turbidity and panicle concentration in the influent and effluent of biological activated carbon filter （BAC） were monitored by on-line turbidimetric apparatus and on-line panicle counters. The results showed that 2-3 hours were needed for BAC filter to mature in reducing turbidity and panicle concentration after being backwashed by water only .Turbidity in the effluent was removed about 10%-30%, and panicle concentration was reduced about 15%-60%. High turbidity and panicle concentration were found in the initial filtrated water of BAC filter, and the analysis of correlation showed that it existed a high relationship between panicle concentration and heterotrophic plate count （HPC）.Meanwhile it showed that large number of heterotrophic bacteria attached on the panicles caused HPC higher in the effluent than that in the influent.
