摘要:
江西某规模化养猪场废水含有高浓度的氨氮和TP以及木质素等难生化降解有机物，经原废水处理系统处理后,出水水质无法达到排放要求。在水质分析的基础上，采用气浮+厌氧池+两级A/O+曝气生物滤池+芬顿氧化+化学除磷组合工艺进行改造。改造后的实际运行结果表明，COD、NH3-N、TP的总去除率分别达到99.4%、96.7%、97.8%，最终出水水质满足江西省《鄱阳湖生态经济区水污染物排放标准》(DB 36/852—2015)。
Abstract:
The wastewater from a large-scale piggery in Jiangxi Province contains high concentration of NH3-N, TP and refractory organic matters, such as lignin. The effluent quality couldnot reach the discharge requirements after the treatment by the original sewage treatment system. On the basis of wastewater quality analysis, the original process was transformed into a combined process of air flotation, anaerobic tank, twostage A/O, aerated biological filter, Fenton oxidation, and chemical phosphorus removal. The practical running results after reconstruction showed that the total removal rate of COD, NH3-N and TP reached 99.4%,96.7% and 97.8%, respectively. The final effluent water quality could meet Wastewater Discharge Standard of Poyang Lake Eco-economic District in Jiangxi Province(DB 36/852-2015).
