新型强化内源反硝化MBR工艺处理高氮、磷污水的研究

Study on New Technology of Enhanced Endogenous Denitrification MBR for High Nitrogen and Phosphorus Sewage

研究了采用新型强化内源反硝化MBR组合工艺处理高氮、磷污水。结果表明,新型强化内源反硝化MBR组合工艺的最佳运行条件为:试验装置总池容40L,污泥龄(SRT)30d,水力停留时间(HRT)为16h。最佳条件下,污水CODcr、氨氮、总磷的去除率分别为86.88%、99.22%和82.4%,出水水质满足《城镇污水处理厂污染物排放标准》一级A标准。

Endogenous denitrification technology was used to deeply treat wastewater containing nitrogen and phosphorus. The results showed that the best effect was obtained at the conditions of sludge age of 30 d, hydraulic retention time of 16 h. Removing efficiency of chemical oxygen demand （COD）, total nitrogen and total phosphorus was 86.88 % ,99.22 % and 57.82 %,respectively ,effluent quality could meet the A level discharge standard of pollutants for municipal wastewater treatment plant.
