摘　　要：针对高温、常温以及低温的微污染水源,采用生物活性炭技术进行现场试验研究.结果表明,生物活性炭工艺在各个水质时期(高温、常温、低温)对水中的有机物的去除率分别为CODMn(51.66%、47.74%、24.15%)、UV254(60.6%、49.99%、17.86%)、TOC(55.17%、24.14%、22.86%).比较而言高温较常温及低温期生物活性炭能够达到更好的效果.同时,生物活性炭工艺细菌在投氯量低的条件下即可被杀灭,没有增加后续工艺消毒剂用量,保证了饮用水的安全性.Comparing studies on treatment of high-temperature, normal-temperature and lowtemperature micropolluted water by biological activitated carbon （BAC） was taken on the basis of a pilot-scale experiment. The results demonstrated that BAC process was able to efficiently remove CODMn（51.66% , 47.74% and 24.15% ） , UV254 （60.6% , 49.99% , 17. 86% ） as well as TOC （55.17% , 24.14% , 22.86% ） , respectively. It was also suggested that BAC was more effective for treating high-temperature water than for normal-temperature or low-temperature water. Meanwhile, bacteria broken from BAC could be effectively killed, even at a relative low chlorine dosage, thus, excessive chlorine for disinfection is not needed. This paper provides an economical method for ensuring the safety of drinking water by using BAC process in water treatment.
