【摘要】 生物曝气滤池是近年来发展起来的一种新型生活污水处理工艺,特别适合于煤矿区等中小规模的生活污水处理,而气水比是影响该工艺运行效果的一个重要参数,论文在不同气水比条件下,研究了曝气生物滤池对矿区生活污水中氨氮、有机物、悬浮物的去除效果,分析了污染物的降解机制,为该工艺在煤炭矿区生活污水处理中的推广应用提供了良好的理论依据及技术参考。更多还原

【Abstract】 The biological aerated filter is a new residential waste water treatment technique developed in the resent and is suitable to the residential waste water treatment in the mining area.The air and water ratio is the important parameters influenced to the operation results of the technique.The paper,under the different air and water ratio,studied the dissolved oxygen density and the mass transfer to the results of the ammoniac nitrogen,organic maters and suspended solids.The paper analyzed the degradation mechanics of the polluted mass,which provided good theory basics and technical references to the application of the residential waste water treatment in coal mining are.更多还原
