中文摘要: |
近年来,随着工业化城镇化的快速发展,大量生活污水未经处理即排放到自然水体中,导致我国地表水水质显著下降,富营养化现象严重,生活污水的处理日益受到广泛重视。人工湿地被证明是处理生活污水的一种经济有效手段,已成为生活污水处理的重要工艺之一。通过较为系统地综述表面流、水平潜流和垂直流3种流程人工湿地在处理生活污水时常用的植物种类、基质类型、水力负荷及净化效果,总结了目前人工湿地在生活污水处理中存在的一些问题,并展望了其未来发展方向。 |
英文摘要: |
Domestic wastewater contains a large amount of nutrients(particularly nitrogen and phosphorus), total suspended solids(TSS) and organic matter, and often causes eutrophification of its receiving water bodies. Treating domestic wastewater has drawn increasing attentions. Constructed wetland systems have showed to be a cost-effective technique for domestic wastewater treatment. This paper summarized commonly used macrophyte species, substrate, hydraulic loading rates(HLR) and removal efficiencies for free surface flow constructed wetlands, horizontal subsurface flow constructed wetlands and vertical subsurface flow constructed wetlands. Further research on constructed wetlands was also proposed. |
