摘　　要：本文研究了SBR系统中pH值、MLSS的变化对同步硝化反硝化的影响。结果表明:在进水水质和反应条件相同时,将pH值控制在8.5,出水水质最好,COD去除率达到90.0%,总氮去除率达到99.4%;在进水水质和反应条件相同,反应器中MLSS为520 mg/L时,出水水质最好,COD去除率达到85.8%,总氮去除率达到99.1%。This article describes a research of the influence on synchronous nitrification and denitrifieation by pH and MISS in sequence batch reactors （SBR）. The result showed that with the same quality of influent and under the same reaction conditions, the quality of effluent was the best when pH was 8.5, and 90.0% of COD and 99.4% of total nitrogen were removed; with the same quality of influent and under the same reaction conditions, the quality of effluent was the best when MISS was 520 mg/L, and COD and total nitrogen were removed by 85.8% and 99.1%, respectively.
