摘　　要：以南方A、B两座臭氧—生物活性炭深度处理水厂为研究对象,探讨了生物活性炭滤池中无脊椎动物的来源及其生长繁殖特点。研究表明,生物活性炭滤池在运行过程中会孳生无脊椎动物,轮虫是无脊椎动物的绝对优势类群,其次是甲壳类浮游动物。在取水口或泵站采用氯等化学药剂灭活原水中的甲壳类动物,是控制生物在水处理系统繁殖和穿透的重要措施;优化砂滤池的运行参数并加强管理,控制生物进入生物活性炭滤池,是解决甲壳类动物穿透的根本途径。对于生物活性炭中孳生的甲壳类浮游动物,可采用药剂反冲洗和药剂浸泡进行去除和灭活。Based on the study of two ozone---BAC advanced water treatment plants-A and B, this paper discusses the origin and breeding characteristics of invertebrates in biological activated carbon filters. The results show that： invertebrates will breed during the operation of BAC filter; rotifer is absolutely the dominant invertebrate and the crustacean zooplankton is the second. Crustacean inactivation with chemicals, such as chlorine, in the water inlet or pumping station is the important measure to control the biological breeding and penetrating in water treatment system; sand filter operation parameters optimization and management improvement to control the biological to get into BAC filter is the fundamental way to solve the crustacean penetration problem. Chemical back-washing and chemical soaking can terminate and inactivate the breeding crustacean in BAC.
