摘要

在不同的水力停留时间(HRT)、温度、碳氮比(COD/N)条件下

研究了波式潜流人工湿地(W-SFCW)试验装置对水体总氮和氨氮的去除效果。通过检测W-SFCW沿程各形态氮的含量

探讨了其对氮的去除原理。结果表明

HRT、温度、COD/N分别为5d

26.8℃

5条件下总氮去除率较高

可达74.92%此外

研究发现氨氮主要在浅水区通过硝化作用转化为NO3-N

所得的NO3-N通过深水区的反硝化作用转化为N2而得以去除。

Abstract

A lot of experiences were conducted in different hydraulic retention time(HRT)

temperature and COD/N to explore the removal efficiency of TN

NH3-N in the water using the wavy subsurface constructed wetland(W-SFCW) test device

and to discuss the nitrogen removal principle by detecting nitrogen removal content in various forms along the path of W-SFCW device.The results showed that total nitrogen rate was higher and could amount to 74.92% when HRT

temperature

COD/ N were 5 d

26.8℃

respectively.In addition

we found that ammonia nitrogen was mainly in shallow water through the nitrification into NO3-N

and the NO3-N was removed through the deep water denitrification into Nz in the deep water.
