摘要
由于三峡库区山多地少,城镇过于分散,若修建污水厂,土地征用困难,建设污水管网费用过高,于是笔者提出了复合式山地湿地污水处理系统的设想。该工艺充分利用山体坡度和水体势能进行跌水曝气,不仅节约了耕地,还极大地节省了运行和管理费用。
Since Three Gorges Reservoir Area is mountainous region with little flat land, towns are separated from each other, so building wastewater plant is unavailable in this area for the difficulty of making a requisition for land and the high investment on building wastewater pipelines. As a result, this paper recommends the integrated constructed terrace wetland because it can make good use of drop aeration, and the wetland covers less land and needs lower cost on running and managing than wastewater plant.
