摘要
以生活污水为介质,在EGSB反应器中接入污泥可以快速培养出颗粒污泥,其有较大的粒径,大多数>0.45 mm,沉降性好。当维持微氧反应器内的HRT为6 h,回流比R为9时,对于进水COD和氨氮去除率分别为80%～90%、80%～90%。运行稳定后出水COD维持在50 mg/L以下,氨氮维持在10 mg/L以下。
In sewage,for medium,access the sludge in the EGSB reactor can quickly produce granular sludge.Its have larger size,the majority of0.45 mm,good settleability.While maintaining anaerobic reactor of HRT for 6 h,reflux ratio R is 9,for water removal rate of COD and ammonia nitrogen is 80%~90%,80%~90% respectively.Running stable after the effluent COD under 50 mg/L,the ammonia nitrogen sustain under 10 mg/L.
