土壤渗滤处理三格化粪池粪液的可行性论证

农村粪便污水的出路问题，是农村生态环境的保护的一个重要方面。当前我国南方农村已较普遍使用“三格化粪池”厕所，该文以滤坑式土壤渗滤进行就地处理，并对其可行性作了卫生学论证，结果表明，渗坑式土壤渗滤就地处理法，对粪水中的大肠菌群，氨氮及化学耗氧量等指标，均具有良好的净化效果，其处理对土壤浅层地下水污染的卫生防护，以１０ｍ为蹁可认为是安全的。

Feasibility Demonstration on Land Permeation Treatment of Nightsoil Sewage from Septic Tank

The way out of nightsoil sewage in rural area is an important aspect of protecting ecological environment. Septic tanks are now widely used in the south rural area in China. In this paper.a land permeation treatment of pit style for nightsoil sewage from septic tank was introduced, and the hygienic feasibility of the treatment was demonstrated. The result showed that the land treatment of nightsoil sewage has a good purificatory effect on the pollutants, such as fecal coliform, COFmn and amino nitrogen. The hygienic protection distance for underground water was considered as 10 meters.
