摘要:- 雄安新区孝义河是白洋淀八条入淀河流之一,为保证白洋淀水质,实施孝义河河口湿地水质净化工程,工程设计处理规模为20×104 m3/d，采用“前置沉淀生态塘+潜流湿地+表流湿地+沉水植物塘”组合处理工艺，工程建成后将成为国内第二大水平潜流湿地。根据设计规范和设计经验预测，当湿地来水满足《地表水环境质量标准》（GB 3838—2002）Ⅳ类标准时，冬季TP去除率≥30%；当来水满足Ⅴ类标准时，出水水质满足Ⅳ类标准；当来水劣于Ⅴ类标准时，冬季TP去除率≥30%，其他主要超标污染物去除率≥20%。工程总占地为1.98 km2，建设成本约2 150 元/m3，处理成本约0.098 元/m3。
Abstract:- Xiaoyi River 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 ×104 m3/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.
