【摘要】 采用自由表面流芦苇湿地处理超稠油废水 .当芦苇床的水力负荷为 3 3 3cm/d时 ,对于年平均进水COD4 59.1 6mg/L ,石油类 2 7 65mg/L ,BOD53 3 52mg/L ,TN 1 3 74mg/L的超稠油废水 ,该系统的出水指标为COD77 2 1mg/L ,石油类 1 4 2mg/L ,BOD53 90mg/L ,TN 1 60mg/L .去除率分别为 :COD 83 1 8% ,石油类 94 86% ,BOD588 3 7% ,TN 88 3 6% ,pH值由 7 87降至 7.77.处理后的超稠油废水对土壤的污染并不明显 ,对芦苇的生长和材质指标几乎没有影响 .可见 ,自由表面流芦苇湿地深度处理超稠油废水的出水水质稳定 ,耐冲击负荷强 ,是一种经济有效的超稠油废水处理新方法更多还原

【Abstract】 This paper adopts a new economic technology of treating super heavy oil produced water using surface flow reed wetland system. The field test was conducted at the average filtration rate of 3 33cm/d. The average influent concentrations per year of COD, Oil, BOD\-5, TN were 459 16mg/L, 27 65mg/L, 33 52mg/L, 13 74mg/L, and the average effluent concentrations per year of above indices were 77 21mg/L, 1 42mg/L, 3 90mg/L, 1 60mg/L, respectively. Its respective removal ratios of COD, Oil, BOD\-5, TN and pH were 83 18%, 94 86%, 88 37%, 88 36%, 7 87～7 77. Analyses showed that super heavy oil produced water had no obvious effect on soil and almost no effect on growth volume and quality of reeds. Results indicated that the surface flow reed wetland could provide an efficient economical, stable new means of treating super heavy oil produced water.更多还原
