为了解决校园绿化用水不足问题,桂林理工大学在雁山校区采用C-MBR工艺建设了处理量200 m3/d的校园污水中水回用工程。运行结果表明,C-MBR工艺对校园污水COD、BOD5、TN、TP、色度、浊度、TSS的去除率分别达到了85.36%、96%、53.04%、74.39%、65.44%、99.69%、100%,出水水质满足GB/T 18920-2002的要求,出水可直接用于校园绿化用水等目的。
Ceramic membrane bio-reactor (C-MBR) process was applied in treating wastewater from the university campus of Guilin University of Technology (GUT). CMBR with submerged flat-sheet ceramic membrane module designed for a Qmax of200 m^3/d. The results showed that by C-MBR process the removal rates of COD, BODs, TN, TP, chromaticity, turbidity and TSS reached 85.36%, 96%, 53.04%, 74.39%, 65.44%, 99.69% and 100%, respectively. The effluent quality met the Urban sewage recycling-urban mixed water quality (GB/T18920-2002), which could be used directly for campus landscaping irrigation.
