新型人工快滤组合技术处理氨氮废水的研究

Study on treatment of ammonia nitrogen wastewaterby new artificial fast filtration combination technology

针对南方地区有些小河(溪)地表水氨氮超标严重,通过新型人工快滤组合技术研究,得出新型人工快滤组合最佳处理技术方案。研究结果表明:氨氮的除去率可达80%,处理后出水水质达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准要求。该技术可推广应用于氨氮超标严重的小河(溪)或分散式农村生活污水处理。

For ammonia nitrogen in the surface water of some small rivers(streams)seriously exceed the standard in the South,on the basis of the study of a new type of artificial fast filtration combination technology,the optimal treatment technology proposal is obtained for a new type of artificial fast filtration combination.The study result shows that the removal rate of ammonia nitrogen could reach up to 80%.After treatment,the water quality of the effluent could meet the requirements of Level B Standard for the Emission of Pollutants in Urban Sewage Treatment Plants(GB18918-2002).This technology could be widely used in the small rivers(streams)or decentralized rural sewage treatment where ammonia nitrogen seriously exceeds the standard.
