摘　　要：调查了南方某净水厂生物活性炭(BAC)池中无脊椎动物的群落结构周年变化。共发现无脊椎动物26种(属或类)。轮虫为优势类群,其次为桡足类及其无节幼体、枝角类、寡毛类。调查期间BAC池炭总管水中无脊椎动物的平均丰度是主臭氧后水的8.2倍,炭滤后水中无脊椎动物的平均丰度是炭滤前水的12～18.7倍。研究结果表明,BAC池是无脊椎动物滋生的重要场所。春夏两季BAC池中无脊椎动物增长较快,水温升高对BAC池中无脊椎动物滋生起促进作用。夏季和其他时期分别以桡足类和轮虫占据优势,存在着小型无脊椎动物(轮虫)向大型无脊椎动物(桡足类)演替的现象。A study was carried out to investigate the invertebrate community structure changes in the biological activated carbon（BAC） filter of some water treatment plant in South China.Totally 26 kinds of invertebrate were discovered.Rotifers were dominant species,and the others are copepods,nauplii larvae,cladocerans,and oligochaetes in declining sequence.During the research,the average invertebrate abundance in the filter was 8.2 times of that in post-inter-ozonation-water,and the average invertebrate abundance after filter was 12 to 18.7 times of that before filter.The research showed that BAC filter was the major spot for invertebrate breeding.During summer and fall,the invertebrate in BAC grow faster than other seasons.The increase of water temperature could improve the invertebrate breeding.In summer and other seasons,the copepods and rotifer were the dominant species respectively,and the succession from small invertebrate（rotifer） to large invertebrate（copepods） also existed.
