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℃
5
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.
