【摘要】 选取不同材料做基质,芦苇为湿地植物,构建了1#和2#二级串联潜流式人工湿地系统,对稠油采出污水进行现场处理试验研究。考察了水力负荷分别为0.18和0.09m3/(m2.d)的1#和2#湿地,不同季节(夏季和冬季)情况下的运行效果。结果表明,夏季人工湿地对石油类、COD、BOD5、TN、SS的去除率分别为79.22%、81.20%、89.67%、87.61%和89.47%;冬季则达到77.57%、78.98%、79.05%、71.35%、89.88%。更多还原

【Abstract】 Seasonal operation performance（in summer and winter）of a subsurface flow constructed wetland（SFCW）for treating heavy oil produced water was carried.The SFCW has two reed beds（No.1 and No.2）in the series arrangement with the hydraulic loading rate of 0.18 and 0.09 m3/（m2·d）for the reed bed No.1 and No.2,respectively.Results obtained show that the SFCW has removal rates of oil,COD_Cr,BOD₅,TN,and SS being 79.22%,81.20%,89.67%,87.61%,and 89.47% in summer,while those figures in winter are 77.57%,78.98%,79.05%,71.35%,and 89.88%,respectively.更多还原
