摘　　要：通过在传统的生态塘中增设了一道活性渗透墙而改造成的内置渗透墙型生态塘。结果表明,内置渗透墙型生态塘对生活污水具有良好的处理效果,在水力负荷为0.05~0.1 m3/m2.d之间时,即水力停留时间在10 d^20 d时,它对COD的去除率在60%以上,对TN的去除率在50%以上,对TP的去除率在75%以上。大大减轻了后序工艺的负担,减少了后序处理设施。从而缩小了整个生态塘系统的占地面积,节省了基建投资,是一种高效的适合农村生活污水处理的技术。A new built - in permeable reactive barrier of ecological pond was built through add a wall of a permeable reactive barrier into traditional ecological pond. The results showed that built - in permeable reactive barrier of ecological pond can reach a good effect for sewage treatment, when the hydraulic loading is between 0.05 and 0.1 m^3/m^2 . d, hydraulic retention time is 10 d - 20 d, the COD removal efficiency is better than 70%, TN removal efficiency is better than 50%, TP removal efficiency is better than 75%. It Reducs the burden largely for follow - up technique and follow - up treatment facilities. Thereby it will reduce the area of entire eco - system and save infrastructure investment, it is a highly effective treatment technology for rural sewage.
