摘要:
采用臭氧接触氧化+生态组合滤池+复合垂直流湿地组合工艺处理某金属表面处理园区污水处理厂尾水，考察了该工艺在夏季与冬季的处理效果。实际运行结果表明，夏季平均进水COD、NH3-N、TN及TP分别为39.3、1.44、8.61、0.38 mg/L，平均总去除率分别为46.3%、91.7%、55.2%、71.1%；冬季平均进水COD、NH3-N、TN及TP分别为43.5、1.80、10.14、0.34 mg/L，平均总去除率分别为29.2%、93.9%、58.6%、76.5%。除COD与总氮指标外，其余出水指标均达到地表水Ⅳ类标准。冬季COD、铜、锌、总铬、六价铬及镍的总去除率均低于夏季，且湿地植物大量死亡（花叶芦竹除外），污染物的去除主要依靠臭氧接触氧化、滤池过滤与反硝化、湿地基质填料吸附与截留作用。
Abstract:
The combined process of ozone oxidation, ecological combination filter, integrated vertical-flow constructed wetland was adopted to treat the tail water of a metal surface treatment park wastewater treatment plant. The treatment effects of this process were investigated in summer and winter. The operation results show that the average influent concentrations of COD, NH3-N, TN, and TP in summer were 39.3 mg/L, 1.44 mg/L, 8.61 mg/L, and 0.38 mg/L, respectively, with average total removal rates of 46.3%, 91.7%, 55.2%, and 71.1%, respectively. In winter, the average influent concentrations of COD, NH3-N, TN, and TP were 43.5 mg/L, 1.80 mg/L, 10.14 mg/L, and 0.34 mg/L, respectively, while the average total removal rates were 29.2%, 93.9%, 58.6%, and 76.5%, respectively. In addition to COD and TN, the other indexes of the effluent quality reached the surface water level Ⅳ standard. The total removal rates of COD, Cu, Zn, total Cr, hexavalent chromium, and Ni in winter were lower than those in summer. And a large number of wetland plants died in winter except Arundo donax. The removal of pollution factors mainly depended on ozone oxidation, filter filtration and denitrification, and adsorption and interception of wetland matrix fillers.
