摘　　要：研究了ω(化学需氧量)／ω(氨氮)、pH值和碱度对普通活性污泥法脱氮的影响,并对试验结果进行了分 析。结果表明,随着ω(化学需氧量)／ω(氨氮)的升高,氨氮去除率下降,平均为39％。系统最适宜的pH值为7.6,进水 的最佳碱度约为350 mg／L。The influence factors including chemical oxygen demand (COD)/NH3-N,pH and alkalinity of de-nitrogen by activated sludge process were investigated, and the test results were analyzed as well. The results indicate that denitrogeneration is decreased along with the increase of COD/ NH3-N, the average valve is 39%. The system reaches optimum when pH value is equal to 7.6, and alkalinity of water inflow is around 350 mg/L.
