摘　　要：采用MBR工艺处理医院废水,出水中p H值、COD、BOD、SS、粪大肠菌群数等各项指标均明显低于GB 18466—2005《医疗机构水污染物排放标准》中的预处理标准,处理效果很好.对比了MBR工艺与传统活性污泥工艺的处理效果,结果表明,MBR工艺在去除医院废水中COD、BOD及SS等方面有明显的优势,COD、BOD、SS的平均去除率分别为91. 24%、96. 21%、91. 82%,而传统工艺的平均去除率分别为61. 95%、69. 38%、66. 10%.The results show that the treatment of hospital wastewater by MBR process is very effective, and the pH, COD, BOD, SS and fecal coli form of effluent are obviously lower than the pre-treatment standard of Discharge Standard of Water Pollutants for Medical Organization （GB 18466-2005）. Comparing the treatment resuhs of MBR process with traditional activated sludge process, the results show that MBR process has obvious advantages in removing COD, BOD and SS in hospital wastewater. The average removal rates of COD, BOD and SS are 91.24% , 96.21% and 91.82% respectively, while the average removal rates of traditional processes are 61.95% , 69.38% and 66.10% respectively.
