摘　　要：地面廊道污水处理系统类似于人工湿地技术,其优点在于该系统应用于污染河流的治理时,对河流地形适应性非常强;另外系统四周不透水的墙体结构使整个廊道起着氧化塘的作用,并且沿坡降由好氧塘逐渐过渡到厌氧塘。本文重点介绍该处理系统的设计,主要包括廊道的选址、水生植物的选择、廊道最佳长度及运行参数的确定。Surface-corridor sewage treatment system is similar to man-made wetland technology.The advantage is that the system can be widely used in all kinds of river terrains and can be applied to dispose polluted rivers.In addition,the waterproof walls structure results in that the system acts as an oxidation pond,which changes from the aerobic pond to the anaerobic pond along with the gradient.This paper mainly introduces the design of the system,including the choosing of corridor's location and macrophytes and establishment of the optimal length of the corridor and operating parameters.
