复合厌氧生物滤池处理铁路高浓度粪便污水

摘要

With the extensive use of EMU and high-speed EMU system in railway operations, a large number of high concentrations of fecal sewage have been produced, and these high concentrations of fecal sewage cannot be directly discharged into the city sewer. This paper focuses on the technical research on hybrid anaerobic filter of low energy consumption for the treatment of high concentrations of fecal sewage of railway. The paper thinks that; hybrid anaerobic filter with a large surface area can always be attached by rich micro-organisms, and it can also hold a mass of activated sludge, so the capacity and efficiency of the degradation of organic matter is higher than traditional methods. Hybrid anaerobic filter has the advantages of simple installation, maintenance-free and low energy consumption, so it is very suitable for the treatment of high concentrations of fecal sewage on railway.%随着动车及高速动车系统在铁路运营中广泛应用,产生了大量的高浓度粪便污水,而这些高浓度粪便污水都不能直接排入城市下水道.着重研究采用一种低动力的复合厌氧处理技术(hybrid anaerobic filter)——HAF处理高浓度粪便污水.HAF复合厌氧生物滤池内的填料有着很大的比表面积,可以附着大量的微生物,生物相丰实,同时依靠填料截留了大量的活性污泥,因此降解有机物的能力和效率比传统的方法大大提高.HAF复合厌氧生物滤池工艺安装简单,无需专人管理,动力消耗低,降解效率高,非常适用于铁路高浓度粪便污水处理.
