摘　　要：对装填新型陶瓷填料和生物陶粒的2个曝气生物滤池系统进行了平行对比试验研究。分析了新型陶瓷填料用于曝气生物滤池处理生活污水的可行性及其优缺点,优化了曝气生物滤池系统运行参数。试验结果表明:在好氧区水力停留时间为1.5 h,进水CODcr、NH4+-N、TP分别为135.6 mg/L、42.1 mg/L、0.69 mg/L时,新型陶瓷填料BAF相应指标去除率依次为81.2%、99.8%、68.1%,生物陶粒BAF相应指标去除率依次为80.8%、99.5%、66.7%,在相同运行条件下,新型陶瓷填料反冲洗耗水量小、冲洗效果好、运行成本低。The BAF for wastewater treatment loaded with new ceramic fillers was investigwed in comparison with the BAF loaded with biogenic ceramisite agitator. The feasibility and features of the new ceramic fillers had been analyzed by comparing the two fillers and the operational parameters had been analyzed and determined at the same time. It is shown are that when the average influent CODer is 135. 6 mg/L, NH4＋ -- N 42.1 mg/L and TP 0.69 mg/L, the removal efficiencies of The BAF loaded with new ceramic fillers and ceramisite agitator are 81.2%, 99.8%, 68.1% and 80.8%, 99.5%, 66.7% respectively at the condition of the HRT= 1.5 h. New ceramic fillers required less water to backwash and had better effect than biogenic ceramisite agitator at the same condition, what is more, the running costs of the BAF loaded with new ceramic fillers were less than that of the BAF loaded with ceramisite agitator.
