华北地区潜流人工湿地运行方案探讨

Operation Scheme of Subsurface flow Constructed Wetland in North China

通过3年的植物试验、覆盖度试验、水力负荷试验、水力停留时间试验,基于层次分析法确定各水质指标值所占权重,对华北地区潜流人工湿地系统运行方案进行了研究,以期最大限度获得潜流人工湿地生态系统水质净化能力,实现湿地生态系统的可持续利用。得出常温运行期、低温运行期和过渡期的较优方案,可供中国北方地区潜流人工湿地设计时参考。

According to the experiments of three years about plant,coverage of plant,hydraulic load and hydraulic retention time,based on AHP to confirm the weight of each water quality index,research the operation scheme of the subsurface flow constructed wetland system in North China.Expect to get the maximum water purification of the subsurface flow constructed wetland ecosystem and realize the sustainable utilization.The operation scheme of the transition period,the Room-temperature period and the Low-temperature period can reference for designing the subsurface flow constructed wetland system in North China.
