摘要
用好氧颗粒污泥(AGS)和好氧颗粒污泥膜生物反应器(AGSMBR)两种体系处理实际小区污水,对其处理效果进行了对比研究.当进水CODCr浓度为300～500 mg/L,TN浓度为40～50 mg/L时,AGS系统和AGSMBR系统出水的CODCr,TN浓度的平均值分别为40.0 mg/L、11.4 mg/L和20.0 mg/L、8.9 mg/L,相应的去除率分别为90.0%,77.7%和95.0%,82.7%.结果表明:两者对小区污水CODCr和TN的去除均取得很好的效果,而AGSMBR出水水质略好.好氧颗粒污泥能减缓膜污染,但对膜组件的作用并不明显.对于小区污水处理而言,AGS系统比AGSMBR系统更具优势.
Aerobic granular sludge （AGS） and aerobic granular sludge membrane bioreactor （AGSMBR） were utilized to treat the sewage in a certain residential district. By comparing the treating effects, it was found that when the influent concentration of CODcr and TN were 300-500 mg/L and 40-50 mg/L, their accordingly averaged effluent concentration through AGS system and AGSMBR system were 40 mg/L, 11.4 mg/L and 20.0 mg/L, 8.9 mg/L, their corresponding removal efficiencies were 90.0 %, 77.7 % and 95.0 %, 82.7 % respectively. Result indicates the high removal efficiencies of CODcr and TN were achieved by both systems but the effluent water quality from AGSMBR system is a little better. The membrane fouling can be mitigated significantly by AGS, but this function to separating membrane was not prominent. So, AGS system is superior to AGSMBR system in residential sewage treatment.
