【摘要】 人工湿地作为一种处理多种污水的绿色环保技术,具有类型多样、土地密集、低能量、低运营要求等特性。其大致可分为两类:自由水面的人工湿地和地下流的人工湿地。目前人工湿地在污水处理中具有广泛的应用,并具有较完善的成本效益分析程序。在人工湿地的设计和操作过程中,需要因地制宜地选择植物和基质,并根据水深、水力负荷、水力滞留时间和流入液的供给模式进行优化。出于长远考虑,还需要对人工湿地的可持续性进行重点研究。更多还原

【Abstract】 Constructed wetland is a green technology to deal with many kinds of wastewater,which is multiform,land intensive,low energy,low operational requirements of the processing system. Constructed wetland can be generally classified into two categories: FWS and SSF. Currently,constructed wetland has wide application and relatively impeccable cost-benefit analysis program.In the design and operation of constructed wetlands,plants and substrates need to be selected according to local conditions and optimized by considering water depth,hydraulic load,hydraulic retention time,and influent feed patterns. For the long term,there is also a need to focus on the sustainability of constructed wetlands.更多还原
