| 摘 要： | 研究了人工湿地在间歇流、连续流进水方式下处理生活污水的效率．并进行了对比分析。在平均水力负荷4.8cm／d时，间歇流和连续流人工湿地COD平均去除率分别为78％和64％；NH3-N平均去除率分别为60％和44％；TP平均去除率均为53％。结果表明，间歇流进水能够提高床体内的含氧量，缓解植物根系放氧不足．提高了污染物去除率。

| Abstract: | Comparative study was made for wastewater treatment efficiency by using batch-flow and continuous-flow constructed wetlands.When hydraulic loading was 4.8 cm/d,the average removal rates of chemical oxygen demand(COD) by batch-flow and continuous-flow constructed wetlands were 78% and 64% respectively.The average removal rates of Ammonia-nitrogen(NH_4-N) were 60% and 44% respectively.Both of the average removal rates of total-phosphorus(TP) were 53%.The results indicated that the batch-flow way of constructed wetland may utilize atmospheric reaeration at a larger degree,increase the quantum of oxygen in wetland bed and remove the contamination. |
