摘　　要：生物接触氧化池和生物陶粒滤池是对微污染原水进行预处理时两种常用的生物反应器。以天津引滦水为处理对象 ,从填料挂膜 ,污染物处理效果 ,以及运行维护管理等方面对两种反应器进行了试验研究。试验结果表明 ,生物陶粒滤池挂膜容易 ,对水中的主要污染物指标处理效率高 ,运行稳定 ,维护管理简单易行 ,比生物接触氧化池更适于处理污染程度较轻的微污染原水。Both bio contact oxidation tank and ceramic bio filter are always adopted for bio pretreatment of micro polluted raw water. The operating performances of these two kinds of reactors were researched experimentally to treat the Luanhe River diverting water in Tianjin in focuses to observe the membrane growth on package material, the pollutant removal and the management and maintenances of the treatment facilities. The results have shown that the ceramic filter possess has superiorities in all these topics with comparison to the bio oxidation contact tank. The bio film grows on ceramic well, the reactor works stable with higher pollutant removal and it is easy to manage and service. It is thought that ceramic bio filter could be a better way than bio contact oxidation tank to pre treat micro polluted raw water.
