摘　　要：试验以《地表水环境质量标准》中劣Ⅴ类微污染水为研究对象,对比传统A/O工艺、投加包埋固定化菌的A/O工艺以及单独使用包埋固定化菌工艺的运行情况,考察了包埋固定化菌处理微污染水的性能。结果表明,使用包埋固定化菌处理劣Ⅴ类微污染水,出水COD、氨氮分别达到地表水环境质量标准中Ⅲ类、Ⅱ类水标准。研究还表明,向传统活性污泥A/O工艺好氧区中添加包埋固定化菌有助于维持微生物浓度稳定,提高出水水质及稳定性。Micro-polluted water which is inferior class V of Environmental Quality Standards for Surface Water has been studied by comparing the operation status of traditional A/O process, A/O process with embedded immobilized bacteria and embedded immobilized bacteria process only. The treatment capacity of embedded immobilized bacteria has been investigated. The results show that the effluent COD and ammonia-nitrogen can reach Class III and Class II water standard of Environmental Quality Standards for Surface Water respectively,after using embedded immobilized bacteria for treating inferior Class V micro-polluted water. The research also shows that adding embedded immobilized bacteria to the aerobic section of traditional activated sludge A/O process is good for keeping the stability of bacteria concentration, improving the effluent water quality and stability.
