摘要
针对传统湿地构型的不足,对潜流湿地构型进行优化,构建一种新型的湿地——递进布水缩变波形潜流人工湿地,并对COD的沿程降解规律及降污效能进行了分析.结果表明:一级动力学模型能较好描述递进布水缩变波形潜流湿地中COD的降解规律,实测COD值与模型预测值较接近,平均误差为7.33%.研究还发现递进布水缩变波形流湿地能有效改善传统湿地对COD和氮的去除效果.
Aimed at the shortage of traditional wetlands conformation, this paper optimized the Subsurface Flow Wetlands （SFW）, advanced a new kind of wetland Wavy Subsurface Flow Constructed Wetlands with contractive section and distributing system by stages. The degradation regulation of COD and treatment performance were discussed. The results show that the first class dynamics model can describe the degradation regulation of COD well. The average error is 7.33%. It is found that this system can improve the removal efficiency of COD and nitrogen.
