摘要
利用兼氧塘、好氧塘和水生植物塘三级串联组成的复合生态塘深度处理石化废水,塘内采用多孔生态混凝土护坡、填料和水生植物浮床等强化措施以增强处理效果。中试试验结果表明:当HRT为2.0 d时,复合生态塘对进水中COD,NH3-N,TN,TP的平均去除率分别为36%,93%,42%,31%,出水主要水质指标皆达到了GB18918—2002《城镇污水处理厂污染物排放标准》中的一级A标准。
Petrochemical wastewater was treated in the ecological pond process combined in series with facultative pond, aerobic pond and hydrophyte pond. The treatment effects of the process were enhanced by means of stephanoporate eco -concrete revetments, fillings and hydrophyte floating beds in the ponds. The pilot test results show that： When HRT is 2.0 d, the removal rates of COD, NH3-N, TN and TP are 36%, 93%, 42%, 31% respectively, and the effluent quality can meet the first grade discharge standard A of GB 18918 -2002.
