地沟式污水生态脱氮处理技术研究

Research on Ditch Type Waste Water Ecological denitrification Technology

地沟式污水土地处理装置,是自然生态净化与人工工艺相结合的小规模污水处理回用系统。该装置具有设备简单、基建投资少、操作管理方便、能耗低等特点,适合处理城镇、社区分散排放的生活污水。文章以贵州省环境科学研究设计院内地沟式土地处理中试装置为例,研究了地沟式污水土地处理系统的脱氮效果及其影响因素,对NH4+-N的去除率可达80％以上。

The ditch type waste water soil treating plant is a small size waste water treatment facility applying the natural ecological purification integrated with the industry process. The unit, simple in construction, low in investment, easy in operation and saved in energy consumption, is applicable for the treatment of dispersed waste water of the small towns and communities. The denitrification performance of the ditch type soil treating system and associated impacting factors are studied based upon the pilot plant operation of Research and Design Institute of Environmental Science of Guizhou Province. Over 80% of NH4+-N can be removed.
