摘要
介绍了人工湿地的分类和特点,发展组合人工湿地的原因及国内外近年来多工艺组合人工湿地发展现状及未来趋势,结合实际分析各个工艺的优点与不足。对多工艺组合人工湿地在我国西北农村地区的使用进行分析和展望,可运用组合人工湿地工艺弥补传统水处理工艺的不足,如光催化高级氧化法与人工湿地组合工艺可有效减少水处理时产生的二次污染和土地占用,使社会效益和经济效益最大化,以期为西北地区组合人工湿地研究提供参考。
This paper introduced the classification and characteristics of constructed wetlands,the reasons for the development of combined wetlands and the development status and future trends of multi-process combined wetlands at home and abroad in recent years.The advantages and disadvantages of each process were analyzed in combination with actual conditions.The use of multi-process combined wetlands in rural areas in northwest China were analyzed and prospected.Combined wetland processes can be used to make up for the deficiencies of traditional water treatment processes.For example,the combination of photocatalytic advanced oxidation and artificial wetlands can effectively reduce Secondary pollution and land occupation,maximize social and economic benefits,so as to provide reference for the study of combined constructed wetlands in the Northwest.
