摘要
采用规模为1 m3/d的MBR处理学生宿舍化粪池出水,考察了普通MBR与生物固定化MBR对氨氮的去除效果。结果表明,采用普通MBR处理高氨氮生活污水时,其对氨氮的去除率不高(<60%)且波动较大;采用生物固定化MBR处理高氨氮生活污水时,其对氨氮的去除率>90%,出水氨氮<10 mg/L,且非常稳定。所投加的生物固定化载体成本低,有利于在实际工程中推广使用。
The removal effects of ammonia nitrogen in sewage from septic tanks of student dormitories by using common MBR and biologically immobilized MBR with treatment capacity of 1 m^3/d were investigated. The results show that when the common MBR is used for treating domestic sewage with high ammonia nitrogen, the removal rate of ammonia nitrogen is below 60% , with a large fluctuation. When the biologically immobilized MBR is used, the removal rate of ammonia nitrogen is above 90% and the effluent ammonia nitrogen is below 10 mg/L, with a good stability. The added biologically immobilized carrier is lower in cost and favourable for the promotion and application in practical projects.
