摘要
采用曝气生物滤池(BAF)系统,进行沸石和普通沙子作为滤料处理模拟农村生活污水的对比实验。实验结果表明,停留时间为8 h,沸石曝气生物滤池(ZBAF)和沙子曝气生物滤池(SBAF)对COD去除率分别为88.39%和79.38%;ZBAF和SBAF对TN去除率分别为72.17%和49.49%。沸石作为曝气生物滤池的填料,更有利于农村生活污水中COD、NH4+-N和TN的去除。ZBAF的出水TN和COD浓度均达到了污水排放国标一级标准。
Rural domestic wastewater treatment was investigated in biological aerated filters(BAF) by using zeliote and sand as filter materials. The removal efficiencies of COD were respectively 88. 39% and 79. 38% in ZBAF and SBAF with the influent flow of 22. 46 m L/min, while TN removal efficiencies were respectively72. 17% and 49. 49% in ZBAF and SBAF. The zeolite as filter material is more effective in rural domestic wastewater treatment,and the effluent COD and nitrogen concentrations in ZBAF complies with the discharge staudards in China.
