硝化菌与膜生物反应器结合处理生活污水中氨氮

Treatment of Ammonia Nitrogen in Residential Sewage by Means of Combination of Nitrobacteria

研究了硝化菌与膜生物反应器结合处理生活污水中氨氮,实验用水采用食堂与化粪池混合水,实验装置采用膜生物反应器,进水氨氮在40mg/L左右,出水氨氮值接近0,实验结果表明出水能够达到国家工业冷却回用水的指标要求,同时COD也降至30mg/L以下,能满足回用要求。

The ammonia nitrogen in residential sewage was treated by means of combination of nitrobacteria. The experiment water was with the water of eatery and cesspool. The experiment device was MBR. The original concentration of ammonia nitrogen was about 40?mg/l ,and the terminal of ammonia nitrogen was about 0. The experiment proved that the content of ammonia nitrogen included in water out meets the national index requirement of industrial cooling reused water, and at the same time, COD is also decreased below 30?mg/l, which also meet the requirement of reused water.
