A wastewater percolation tank and a wastewater percolation system

A wastewater percolation tank and a wastewater percolation system are disclosed. Broken stone the specific surface area of which is large is adopted as a filler layer of the system, thus increasing the contact area between wastewater and a biomembrane and increasing the wastewater treatment efficiency. The wastewater percolation tank and the wastewater percolation system have characteristics of low energy consumption, good nitrogen removing and phosphorus removing effects, a low construction cost, convenient management and operation, a low treatment cost, and the like. The bottom of the wastewater percolation tank is provided with aeration pipes to supply sufficient dissolved oxygen for the equipment, thus increasing the pollutant degradation rate. 本发明公开了种污水渗滤池和种污水渗滤系统，本发明处理系统采用比表面积较大的碎石作为填料层，增大污水与生物膜的接触面积，提高了污水处理效率，具有能耗低，脱氮除磷效果好，造价成本低，管理运行方便，处理费用低等的特点，同时污水渗滤池底部设置有曝气管，为装置提供充足的溶解氧，提高污染物降解速率。
