摘　　要：以模拟生活污水为研究对象,采用双污泥SBR反应器进行反硝化除磷效果的试验研究。研究结果表明,在初始情况相同情况下,乙酸钠是更利于反硝化除磷系统利用的碳源,总磷的去除率为92.8%;进水COD浓度为150 mg/L时,缺氧吸磷的效果最好,磷去除率达到92%,整个过程运行稳定。The test used simulated domestic wastewater as the research object, and adopted two-sludge SBR reactor to make a study of denitrif ying phosphorus removal. The results show that, in the same initial condition, sodium acetate is a carbon source which is better for the use of de nitrifying phosphorus removal system, and the removal rate of total phosphorus is 92.8%. When the ilffluent COD of 150 mg/L, the effect of hy poxia was the best, the removal rate of phosphorus was 92% , and the whole process was stable.
