| 摘 要： | 通过小试研究了气浮-好气滤池工艺提高二级出水水质的应用效果.结果表明,在高、中、低浓度进水水质条件下,气浮-好气滤池工艺具有良好的适应性,工艺对色度、COD、氨氮、总磷、浊度等指标的平均去除率分别是64.8%、47.0%、80%、83%、77.8%.中、低浓度进水水质条件下,出水水质达到城市污水排放一级A标准(GB/T18918—2002)和城市杂用水水质标准(GB/T18920—2002);同时UV254和细菌也得到很好的去除,平均去除率达到了45.7%和62.5%.另外试验结果显示,工艺流程前段气浮单元对有机物、浊度、总磷及UV254的去除起到关键作用,而后续的好气滤池单元主要降低了氨氮浓度,对浊度、有机物的去除起到把关作用.

| Abstract: | The grouping technology of dissolved air flotation and aerobic filters are optimal to wastewater advanced treatment.Tests of improving secondary effluent by dissolved air flotation-aerobic filter's process are studied.The results indicate that the flotation-aerobic filters process can adapt well to different influent concentration,including high,middle and low concentration.The average removal rates of colority,COD,ammonia nitrogen,total phosphor and turbidity by flotation-aerobic filter's processes are 64.... |
