气浮设备在农业面源污染治理中的应用研究——以鱼台县为例

Research on the Application of Air Flotation Equipment in the Treatment of Agricultural Non-point Source Pollution——Take Yutai County as an Example

为有效治理农业面源污染,本文以移动式气浮设备为核心,结合高效水质底质改良剂和高效氨氮去除剂,分别对农田沟渠积水、水产养殖池塘污水和纳污坑塘积水进行治理。研究结果表明,本工艺对农田沟渠积水的COD、NH_(3)-N、TP、SS去除率分别为74.3%、80.7%、90.7%、82.2%;对水产养殖池塘污水的COD、NH_(3)-N、TP、SS去除率分别为57.1%、68.7%、88.4%、91.1%;对纳污坑塘积水的COD、NH_(3)-N、TP、SS去除率分别为71.6%、94.8%、94.4%、91.1%。

In order to effectively control agricultural non-point source pollution,this paper uses mobile air flotation equipment as the core,combined with high-efficiency water quality bottom quality improvers and high-efficiency ammonia nitrogen removers,to treat the stagnant water of farmland ditches,the sewage of aquaculture ponds and the stagnant water of sewage pits and ponds respectively.The research results show that the removal rates of COD,NH_(3)-N,TP,and SS for the stagnant water of farmland ditches by this process are 74.3%,80.7%,90.7%,and 82.2%,respectively;the removal rates of COD,NH_(3)-N,TP,and SS for the sewage of aquaculture ponds were 57.1%,68.7%,88.4%,and 91.1%,respectively;the removal rates of COD,NH_(3)-N,TP,and SS for the stagnant water of sewage pits were 71.6%,94.8%,94.4%,and 91.1%,respectively.
