摘　　要：在南宁市中试基地以复合型自然净化系统、植物浮床以及传统氧化塘系统为研究对象,考察不同系统间的处理效率的差异.系统进水取自南宁市某污水河,并且采用连续进水与连续出水的方式运行.研究主要分为小试和中试两部分.小试实验研究主要是为了筛选好性能较好的植被.中试是通过对不同系统对污染物去除率的对比,找出适合自然净化的系统.研究结果表明,狐尾藻、风车草以及美人蕉的净化效果比较好;此外,得出复合型自然净化系统(A1)、复合型自然净化系统(A2)、传统氧化塘系统以及植物浮床对试验池A1、A2、B1、B2的COD模型分别为A1:y=0.751 3x0.872 5;A2:y=0.905 2x0.761 3;B1:y=0.831 9x0.924 6;B2:y=0.651 2x0.970 7.The compound natural purification system,plant floating bed and traditional oxidation pond system were studied on Nanning experimental base,and each system owns continuous inflow water and effluent water.Besides the difference of each system＇ s treatment efficiency is put on great concern.The research can be divided into two parts—a small pilot study and pilot plant test.The small pilot study was done for screening which vegetation owns a better purification effect.The pilot plant test was used for finding out a suitable natural purification system.The research results showed that the purification effect of foxtail algal,windmill grass and canna was better.Besides that,the model of COD for the compound natural purification system （A1）,the compound natural purification system （A2）,the traditional oxidation pond system and the plant floating bed for CODMn was A1：y =0.7513x0.8725; A2：y =0.9052x0.7613; B1：y =0.8319x0.9246; B2：y =0.6512x0.9707.
