摘要
比较了MBR和MSBR两种工艺的脱氮效果,结果表明：MBR工艺系统运行稳定,脱氮效果明显,氨氮去除率为89％～98％,TN去除率为58％～68％;出水氨氮和TN达到《城镇污水处理厂污染物排放标准》一级A标准;氨氮和TN的去除主要在MBR生化池完成,膜池去除效果不明显.MSBR工艺脱氮效率低于MBR工艺,相同进水条件下的氨氮去除率为84％～98％,TN去除率为54％～63％.
Two kinds of technology of MBR and MSBR were compared,the results showed that the operation of MBR system is stable.The removal effect of ammonia nitrogen and total nitrogen was obvious,the efficiency of ammonia nitrogen was between 89% to 98%,and the total nitrogen removal rate was between 58% to 68%.The effluent quality met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.The nutrient removal rate of MSBR was lower than MBR.The efficiency of ammonia nitrogen was between 84% to 98%,and the total nitrogen removal rate was between 54% to 63%.
