近年来，随着环境立法的日益严格，农村地区的污水处理问题日益受到关注。选择最合适的现场净化系统是基于中国农村地区可负担性和适宜性的关键问题。介绍了一种种植柳树的综合家庭人工湿地系统，用于处理中国北部农村生活污水。IHCW预制框架结构坚固耐用，防水。它可以按照一套标准规格进行批量生产和安装。IHCW对BOD5、TSS、NH4-N和TP的总去除效率分别为96.0%、97.0%、88.4%和87.8%。系统上0.4米的生物质层覆盖提供了显著的系统隔热性能，在寒冷的冬季条件下保持了良好的处理性能。该系统具有成本效益，不需要任何操作能源投入，证明了其在发展中国家单户使用的可行性。
As environmental legislation has become stricter in recent years, the issue of wastewater treatment in rural areas has become an increasing concern. Choice of the most suitable on-site purification systems is based on the key issues of affordability and appropriateness in Chinese rural areas. This paper describes an integrated household constructed wetland (IHCW) system planted with willow (Salix babylonica) to treat household domestic wastewater in rural villages in northern China. The precast frame structure of IHCW is strong and waterproof. It can be mass-produced and installed per a standard set of specifications. The IHCW has achieved high overall removal efficiencies for BOD5, TSS, NH4-N, and TP: 96.0%, 97.0%, 88.4% and 87.8%, respectively. A 0.4 m biomass layer cover on the system provided significant system thermal insulation, maintaining high treatment performance in freezing winter conditions. The system is cost effective and does not need any operational energy inputs, demonstrating its feasibility for single-family use in developing countries.
