摘要
农村生活污水具有分散性强、水质水量波动大、间歇排放等特征,其污染问题成为影响农村生态环境的重要因素,现有城镇污水处理工艺与系统已无法满足农村生活污水治理要求。人工湿地被认为是一种高效、易于使用、环境友好、投资维护费用低的污水处理技术,在农村生活污水处理中具有广阔的应用前景。首先介绍了农村生活污水水质特征,阐述了人工湿地处理技术基本原理,论述了目前报道的多种不同类型的人工湿地处理系统及其在农村生活污水处理中的应用,并分析了水环境因素以及设计操作条件对其处理效率的影响。最后对人工湿地技术处理农村生活污水未来的发展方向作以展望,以期为人工湿地技术处理不同地区农村生活污水相关研究提供理论参考。
Rural domestic wastewater exhibits characteristics such as strong dispersion,significant fluctuations in water quality and quantity,and intermittent discharge.This pollution issue has emerged as a crucial factor impacting the rural ecological environment,as traditional urban wastewater treatment processes and systems are inadequate for treating rural domestic wastewater.Constructed Wetlands(CWs)are recognized as an effective,user-friendly,environmentally sustainable,cost-efficient wastewater treatment technology with promising applications in rural areas.The paper commences by outlining the water quality features of rural domestic wastewater,explaining the fundamental principles of CWs treatment technology,exploring diverse types of CWs treatment systems and their suitability for rural domestic wastewater treatment,and assessing the impact of environmental factors,as well as design and operational conditions,on treatment efficiency.Finally,it forecasts the future development trajectory of CWs technology for rural domestic wastewater treatment,aiming to furnish theoretical insights for research on leveraging CWs technology for treating rural domestic wastewater.
