摘要
采用前置反硝化曝气生物滤池(BAF)工艺处理微污染景观河水。结果表明,试验期间在水力负荷为0.64m.3m-.2h-1的情况下,BAF处理微污染景观河水的较佳工况为:非曝气与曝气区的体积比为1:1、气水体积比为5:1、体积回流比为300%,对CODMn的平均去除率为83.7%、氨氮的平均去除率为91.5%、总氮的平均去除率为72%、总磷的平均去除率为61%。
An experiment was carried out on the slightly polluted landscape river using biological aerated filter（BAF） with pre-denitrification process.The result showed that during the trial period when the hydraulic loading was in the case of 0.64 m3·m-2·h-1,the better conditions were： non-aeration and aeration area volume ratio of 1：1,gas-water ratio of 5：1 and reflux ratio of 300%.The treatment effect were： the average removal rate of CODMn was 83.7%,the average removal rate of NH3-N was 91.5%,the average removal rate of TN was 72%,the average removal rate of TP was 61%.
