The result shows that the recycling effluent upgrades significantly the removal for BOD_5,COD,SS,and NH~+_4-N,and BOD_5 removal rate meets the Monod equation;most part of NH~+_4-N is nitrified and the removal rate of NH~+_4-N is linear with the surface loading rate.Along with the nitrification,alk...

结果表明：循环出水显著提高了对BOD5、COD、SS和NH+4-N的去除率，且对BOD5的去除满足Monod方程；大部分NH+4-N的去除率与其表4-N被硝化，对NH+面负荷率呈线性关系；随着硝化反应的进行，碱度减少，pH值不断降低；循环出水可引入部分氧气，延长了污染物和附着于植物根系微生物的接触时间，提高了对污染物的去除率。
