摘　　要：研究了温度和反冲洗对生物滤池的影响。试验结果表明,生物活性和生物量随温度的降低而下降,有机物的去除率和去除量受温度影响不明显,温度对氨氮和亚硝酸盐氮的去除率和去除量有一定影响;反冲洗使生物量减少,同时提高了生物活性,有机物、氨氮的去除率在反冲洗2h后基本恢复到反冲洗前的水平。This paper studied the influences of temperature and backwashing on bio-filter. The test results showed： the biological activity and quantity decreased with the decrease of temperature; temperature had weak influences on the efficiency and quantity of the organic matter removal, but it had some influence on the ammonia nitrogen and nitrite nitrogen removal efficiency and quantity; backwashing could decrease the biomass and improve biological activity; the organic matter and ammonia nitrogen removal efficiency would recover to the level before backwashing.

关 键 词：饮用水 生物滤池 温度 反冲洗 生物量 生物活性 去除率
