中文摘要：

稳定塘是目前应用比较广泛的污水处理技术，如果塘系统防渗处理不当，会导致地下水的污染．把稳定塘中污染质的下渗过程看作一种单元系统，提出了概化的稳定塘中污染质下渗单元耦合功能模型，对各功能层的功能进行了描述．通过对国内外功能模型研究现状的分析，提出了符合我国现状的对策．

英文摘要：

As the most popular wastewater treatment technology in the world, wastewater stabilization pond system （WSPS） will cause secondary environmental pollution if the seepage System isn＇t treated suitable. The percolation process of WSPS is taken as a unit, and a simplified contamination percolation process combined functional model is put forward, in which includes four layers as bottom sludge layer, substrate layer. The function of every layer is depicted as well as the Current status quo of studies about the functional model is introduced,and some proposals are tabled on the ground of China＇ s status.
