人工湿地在农村生活污水处理中的研究与应用

摘要

With the development of new socialist countryside construction in China,rural environmental management work is steadily unfolding.As an important part of environmental management,rural wastewater treatment is affected by economic conditions and other factors.Energy saving constructed wetland becomes a main choice of rural wastewater treatment technology.The paper reviewed the current researches and projects of constructed wetland for rural wastewater treatment,presented common fillers and plants used in constructed wetland,and summarized and analyzed the operation effect of combined constructed wetland process,muti-stage constructed wetland process and single stage constructed wetland process for rural wastewater treatment.At the same time,the paper analyzed and compared the investment and operating costs of combined constructed wetland process based on the actual wastewater treatment engineering and prospected the focus of attention about this technology in future.%随着社会主义新农村建设步伐的推进,农村环境治理工作正在稳步展开,而农村生活污水处理是其中的重要组成部分.受经济条件等因素的限制,节能型的人工湿地无疑成为农村污水处理技术的主要选择.通过对国内利用人工湿地技术处理农村生活污水的研究和实践进行总结,归纳出常用的湿地填料和湿地植物,对人工湿地组合工艺、多级人工湿地工艺和单级人工湿地工艺的运行效果进行了总结和分析.文中还针对实际工程,分析比较了人工湿地组合工艺的投资和运行费用并对该技术下一步需关注的重点进行了展望.
