摘　　要：将光合细菌、枯草芽胞杆菌、放线菌、硝化细菌和反硝化细菌共同固定在同一个载体内,构建成简单的人工微生态系统研究其对养殖水体的脱氮作用.结果表明,微生物共固定化对养殖水体脱氮效果优良,对氨氮、硝基氮、亚硝基氮的降解率可达85.0%、79.3%、87.3%.The effects of a simple microecosystem of immobilized microbes including photosynthetic bacteria, Bacillus subtilis, actinomyces, nitrobacteria and denitrifying bacteria on the denitrification of aquiculture water body were studied. The results indicated after the aquicuhure water was treated with immobilized microbes,the concentrations of ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in aquatic ecosystem obviously decreased by 85.0 %,79.3 % and 87.3 %.
