人工湿地生态净化技术在“秀美乡村”建设中的应用

Application of Artificial Wetland Ecological Purification Technology in Beautiful Country Construction

通过对传统湿地技术的创新改进,建立了"生态塘+生态沟渠+人工湿地"为核心的农村污水湿地生态净化处理模式,经检测,出水水质达到了《城镇污水处理厂污染物排放标准GB18918—2002》一级A标准,具有投资和运行费用低、处理效果佳、出水水质稳定及景观效果好等优势,可广泛推广应用于"秀美乡村"建设。

By improving traditional wetland technology, the study built a rural sewage ecological purification model with ＂ecological pond ＋ ecological ditch ＋ artificial wetland＂ as the core. The results of the detection showed that the outflow water quality reached the first Class A standard of Urban Sewage Treatment Plant Pollution Emission Standards GB18918-2002. The techniques had advantages of high removal efficiency, stable outflow water quality and good landscape effects with low investment and running expenses, which were suitable for the broad promotion and application in beautiful country construction.
