  摘要:

  雄安新区孝义河是白洋淀八条入淀河道之一,为包管白洋淀水质,实行孝义河河口湿地水质净化项目,项目设想处置范围为20×10^{4m3/d，采取“前置沉淀生态塘+潜流湿地+表流湿地+沉水动物塘”组合处置工艺，项目建成后将成为国内第二洪流平潜流湿地。按照设想规范和设想经验猜测，当湿地来水知足《地表水情况质量尺度》（GB 3838—2002）Ⅳ类尺度时，冬季TP去除率≥30%；当来水知足Ⅴ类尺度时，出水水质知足Ⅳ类尺度；当来水劣在Ⅴ类尺度时，冬季TP去除率≥30%，其他首要超标污染物去除率≥20%。项目总占地为1.98 km2，扶植本钱约2 150元/m3，处置本钱约0.098 元/m3。}

  Abstract:

  XiaoyiRiver in Xiongan New Area is one of the eight rivers flowing into Baiyang Lake. In order to purify water in Xiaoyi River, the river estuary constructed wetland project was constructed, the treatment capacity of which was 20×104m3/d. The treatment process was combined by“pre-precipitation ecological pond + subsurface wetland + surface wetland + submerged plant pond ”, the project would become the second largest horizontal subsurface wetland in China. Prediction based on design specification and engineering experience, if the wetland inflow could meet the class Ⅳ standard of Environmental Quality Standards for Surface Water (GB 3838-2002), total phosphorus(TP) removal would be required not lower than 30% in winter; if the inflow could meet the class Ⅴ standard, the effluent should meet the class Ⅳ standard;if the inflow quality is worse than the class Ⅴ standard, TP removal should be above 30% in winter, and the other major over-standard pollutants removal ought to be more than 20%. The area of this project was 1.98 km2, the construction cost of this project was 2 150 yuan/m3, and the operation cost was 0.098 yuan/m3.
