摘　　要：采用折流板反应器反硝化除磷的双泥系统,考察了反硝化除磷效果。结果表明,在污泥龄为20 d,MLSS为4 000 mg/L,水力停留时间、硝化液回流比分别控制为11.73 h、280%时,反应器对总氮的去除率达64.9%,氨氮去除率达99.9%,CODCr去除率达88.7%,PO43-去除率达92.39%,出水浓度分别为14.2、0.04、22.7、0.37 mg/L。The two-sludge system based on the ABR reactor for the denitrifying phosphate removal is used to test the effect of the enitrifying phosphate removal.The result shows that the reactor could remove about 64.9% of the total nitrogen,99.9% of the ammonia and nitrogen,88.7% of the CODCr,92.39% of the phosphorus,and the concentration of effluent is 14.2,0.04,22.7,0.37 mg/L respectively when SRT was 20 d,MLSS was 4 000 mg/L,HRT was 11.73 hours,and the percent of nitration reflow was 280%.
