人工坡地不同深度COD去除率的变化研究

The Removal of COD of Different Depth in the System of Constructed Sloping Lands

利用人工坡地处理低浓度污水,借鉴了人工湿地原理,用特定的泥沙构筑简单坡地,污水自上而下从坡顶上端流向坡底,在过滤、渗透及其它物理过程中得到降解。由于系统有一定水力负荷,进水污染物浓度(COD)和流量不一定初始配置就合适,需要通过实验逐步调整。然后对上述两方面估算,得出整个系统适宜处理工况。

Make use of the constructed slope lands to deal with the waste water of low density , drawing lessons from the principle of constructed wetlands, to construct the simple sloping lands with the particular sands, the waste water flow the sloping lands from top to bottom, be declined in the filtration, pervasion and other physical processes. Because the system contains certain hydraulic charge, the cod and flux are uncertain at the beginning, they need to be adjusted gradually during the experiment. Then to estimate the above - mentioned two sides, get a feat working condition.
