嘉陵江流域农村生活污水处理细胞工程探索——以“农家乐生态肾”设计为例

Exploring on the Cell Engineering of Rural Domestic Sewage Treatment in Jialing River Area: the Design of Ecological Kidney in the Farmer Household Tourism as Case Study

最近十多年在我国西南地区农村迅速兴起乡村旅游度假新形式"农家乐",其数量和规模都呈快速增长,影响越来越大,由于其粗放式经营其排放的生活污水对地表水环境质量的威胁因量大面广,日益带来不容忽视的问题。本文提出了农家乐"生态肾"概念,即专门用于农家乐生活污水处理的微型人工湿地系统。以位于嘉陵江上游的四川省广元市和平村农家乐为例,对农家乐生活污水处理的微型湿地生态经济系统进行设计和试验,对其综合效益进行了初步评估。研究表明,作为兼具多功能效益的农家乐微型湿地系统,以其环保经济、低碳高效,既解决了局部的环境保护和可持续发展问题,也为流域水环境保护和治理提供了借鉴,具有良好的示范作用和推广价值。

The farmer household tourism is an important way of Chinese rural economic development,but sewage discharged by the farmhouse produce the great threat to surface water environmental quality,which is not a concern to take lightly due to the enormous quantity wide.The farmhouse'ecological kidney'concept was proposed in this paper,which is the miniature artificial wetland system used for farmhouse sewage treatment specially.The farmer household tourism,which is located in the upper reaches of Jialing River,Heping village in Guangyuan City,Sichuan Province,its design system of the miniature constructed wetland system used for farmhouse sewage treatment was analyzed,and its comprehensive benefits was assessed.Studies show the farmhouse miniature constructed wetland system not only can solve the problems of environment and development for peasants,but also provide a reference for the basin water environmental protection,and a good potential of popularization.
