| 摘 要： | 从试验原水中分离出28株高活性菌株,采用人工循环固定方式启动生物增强活性炭工艺,处理低温微污染原水,通过对其处理效能和活性炭上微生物特性的研究,结果表明:原水经生物增强活性炭工艺处理后,其对UV254、TOC、THMFP平均去除率分别为57.4%,45.2%,33.5%;活性炭上微生物量在长时期内保持相对稳定,上层和下层微生物量为分别为(4～5)×108和(2～3)×108CFU/g,而生物活性随着运行时间的延长缓慢下降.上层和下层SOUR值分别从最初1.1 ×10-3和0.75×10-3mg O2/(cm3·h)下降到0.8×10-3和0.6×10-3mg O2/(cm3·h),其主要原因为土著杂菌低量、持续侵入系统,对高活性菌群的生态位造成了一定的冲击.

| Abstract: | High active bacteria were bred from the 28 Dominance bacteria obtained from raw water by several select techniques and continual domestication,and then the enhanced activated carbon was formed by circular immobilization.Pilot plant research of the enhanced activated carbon treatment schemes was conducted for the polluted raw water.The analysis data showed that during the testing period,the average removal rates of UV254,TOC and THMFP were 57.4%,45.2% and 33.5% respectively.The bacteria on activated carbon i... |
