Application of Layered Media as Substrate in Infiltration Treatment System for Municipal Wastewater Treatment*
In this paper, a layered media was used as substrate in a infiltration treatment system for municipal wastewater treatment. The efficiency of this system on nitrogen removal was compared with that by traditional used gravel and the surface characteristics of the layered media were analyzed using SEM. The results show that the layered media used as substrate in infiltration treatment system for wastewater treatment is more efficient on nitrogen removal than gravel. In the system, artificial soil provides storage for contaminants and bio-ceramics support the living organisms. The alternative running of reactor with 12 hours feeding followed by 12 hours break may supply changing environments between oxidative and anoxic in the system which is important for nitrogen removal.
