摘　　要：通过对常规市政污水处理工艺进行优化,利用系统内碳源,来研究反硝化脱氮的效果,实验结果表明:常规工艺的总氮去除率最高为49.2%,最低只有15.8%,平均去除率为34.1%,通过不断优化改进工艺,总氮去除率达到了最高为75.6%,最低为53.2%,平均去除率为65%;当进水总氮不大于40 mg/L时,按总氮平均去除率65%计算,出水总氮在14 mg/L以下,如按最高去除率75.6%计算,出水总氮可达到10 mg/L以下。By optimizing the conventional municipal wastewater treatment process and utilizing the internal carbon source of the process system to study the effect of denitrification.The experimental results showed that the maximum total nitrogen removal rate of conventional process was 49.2%,the minimum was 15.8%,and the average removal rate was 34.1%.Through continuous optimization and improvement of the process,the maximum total nitrogen removal rate reached 75.6%,the minimum was 53.2%,and the average removal rate was 65%;Under the total nitrogen in the influent is not more than 40 mg/L,the total nitrogen in the effluent was less than 14 mg/L when the average removal rate of total nitrogen was 65%.When the maximum removal rate was 75.6%,the total nitrogen in the effluent could be less than 10 mg/L.
