| Abstract: | A comparative study on nitrogen removal in subsurface constructed wetlands with combination matrix and coal matrix was conducted.The results indicate that the removal efficiency of nitrogen in the combination matrix constructed wetland is higher.The average removal rate of ammonia nitrogen and total nitrogen reach 81.9% and 75.7%.While in the coal matrix constructed wetland,the removal efficiency of nitrogen is comparatively lower,and the average removal rate of ammonia nitrogen and total nitrogen reach onl... |
