MBR处理高浓度生活污水试验研究

Treatment of High Concentration Domestic Wastewater by MBR Technique

将传统的A/O工艺与膜分离技术相结合,构建缺氧-MBR工艺。以某单位化粪池上清液为降解对象,测定系统降解各污染指标的能力。结果表明:该工艺具有较好的抗冲击负荷能力,COD出水低于50 mg/L,优于《城镇污水处理厂污染物排放标准》中的一级A标准;虽然进水氨氮浓度较高,但去除率仍高于60%。

The process of anoxic -aerobic MBR is built by combining the traditional A/O process with membrane separation technology. The study targets a unit of septic tanks on clear liquid to measure ability of the system to degrade each pollution index. The result shows that the technology process has a strong resist impact load capability, the effluent COD concentration is below 50 mg/L which is better than the first level A standard of discharge standard of pollutants for municipal wastewater treatment plan. The efficiency of NH4^＋ - N removal is still higher than 60% , although the inlet NH4^＋ - N concentration is high.
