Abstract:

The engineering application effects of the combined process, Anoxic-MBR (membrane bioreactor)-coag-ulation for treating domestic sewage in tourist scenic spots have been researched.The research results show that the removing rates of COD, BOD₅, NH₃-N and TP are all above 85%.The effluent water quality is stable, reaching the Level I-A standard discharge limit value specified in the Discharge Standard of Pollutants from Urban Wastewater Treatment Plants (GB 18918-2002).After disinfected with chlorine tablets, part of effluent can be used for green watering or in scenic spots, so as to substitute fresh tap water.

Key words: membrane bioreactor, coagulation, denitrification, dephosphorization, disinfection, reuse

摘要：

研究了缺氧-MBR-混凝工艺处理旅游景区生活污水的应用效果。研究结果表明：COD、BOD₅、NH₃-N、TP的去除率均在85%以上，出水水质可稳定达到《城镇污水处理厂污染物排放标准》（GB 18918-2002）一级A标准排放限值。部分出水经氯片消毒后回用于绿化浇灌和景观用水，以替代新鲜自来水。
