人工湿地床体中水质指标迁移转化规律研究
Study on the Transport and Transfer Laws of Water Quality Indexes in Subsurface Flow Constructed wetlands
摘要
Abstract
The effect of horizontal subsurface flow constructed wetland on treatment effect of domestic sewage as well as the transport and transfer laws of COD, NH4 + -N, TN and TP in the wetland were studied at the hydraulic retention time of 1 d. The results showed that the degradation of COD was mainly completed in the front and upper of wetland; the concentration of NH4+ -N decreased along the flow path of wetland, while increased with the increasing water levels; the concentration of total nitrogen was higher in the front of wetland ,but lower in the back; the concentration of phosphorus decreased along the wetland, and the trend was significant. The study provided theoretical support for the design and long-term effective function of wetland.关键词
