摘　　要：填料的选择对于生物接触氧化池的运行非常重要。以齿轮型流化生物载体为填料,对生物接触氧化池预处理微污染水源水进行了系统的中试研究。结果表明,以齿轮型流化生物载体为填料的生物接触氧化池在7天内启动成功,且生物量丰富。载体的流化状态好,氨氮处理效率高,气水比选择1∶2为宜。长期监测表明,生物接触氧化池对氨氮平均去除率为80.26%,对锰的去除率为34.50%,但对有机物去除不稳定。结合分子生物学研究表明,生物接触氧化池在预处理水源水时,载体表面菌属种群丰富,且功能菌属与其去除氨氮、锰和有机物的效能有直接关联,功能菌群数量越高,处理效果越好。An appropriate filter is crucial to the biological contact oxidation tank. Gear-type flu- idized filter was used in the pilot-scale biological contact oxidation tank for pretreatment of micro- polluted source water. The results showed that the reactor could successfully started up within on- ly 7 days and the biomass in it was flourishing; the fluidization state was in good condition and am- monia nitrogen removal efficiency was high; the optimal air to water ratio was 1 ： 2. Long term ex- periment showed that average removal rates of ammonia and manganese were 80. 26% and 34. 50%, respectively, but the organic matter removal was not stable. The molecular biology study showed that the filter surface bacteria population in biological contact oxidation tank during source water pre-treatment was rich： the functional bacteria had direct relation with the removal effects of ammonia ni- trogen, manganese and organic matter; the higher bacteria population, the better removal effect.
