徐州市奎河河流——地下水渗流系统处理水体中氮

Xuzhou Kui River Groundwater Infiltration System for Treating Nitrogen in Water Body

基于污水土地处理系统可以渗漏形式补给地下水的特点,利用现场调查分析的方法,提出了一种新的污水土地处理方式——河流——地下水渗流系统去除污水中氮。结果表明,河流——地下水饱和渗流系统对氮污染组分具有很高的去除作用,在距河流40m处对污水中氮的去除率达95％以上,且不受季节变化的影响。在选定环境的特定条件下,处理效果几乎不受河流——地下水界面厚度的影响。

Considering recharging groundwater and soils' role in the wastewater land-treatment system, nitrogen removal of one new treatment method, river groundwater infiltration system, has been studied by the field sampling method. The result showed that when the infiltration system was saturated, elimination of nitrogen has occurred, with a decrease of 95% at least, and doesn't vary with the seasons conditions of the study area, the nitrogen removal efficiency was not various with the river groundwater interface thickness.
