| 摘 要： | 在缺氧／好氧工艺的不同回流比条件下，对处理效果特别是脱氮效果进行了研究。结果表明，混合液和污泥合并回流，当回流比从R=4到R=7时，均能获得良好的脱氮效果，TN去除率达到75．4％以上，出水TN〈10mg／L。而回流比的变化对BOD的去除效果影响较小。当BOD污泥负荷从0．096kg／（kg·d）降低到0．063ks／（kg·d）时，对TN和BOD的去除率影响都很小。

| Abstract: | The effects on the removal under different recirculation rate(R) were investigated in anoxic/oxic(A/O) process,especially on the removal effciency of nitrogen.Under the conditions of R that ranged from 4 to 7,the result showed that the nitrogen removal efficiency could reach a high level when liquor and sludge were recycled together.The total nitrogen removal efficiency was above 75.4%,and TN<10 mg/L in effluent.However the change of R had little effect on the BOD removal.When the sludge load range reduced ... |
