Treatment of Campus Wastewater by a Novel Construction Solid Waste (CSW) Based on Constructed Wetland System
(0) In this article,a laboratory scale multi-stage constructed wetland system was studied for assessing the feasibility of using construction solid waste(CSW) as main substrate of reed bed systems.As a novel material,CSW demonstrated an excellent P removal performance with the P removal efficiency ranging from 96.2 to 99.9%.A tidal-flow operation strategy was also employed to enhance the wetland aeration,which would benefit both the organic pollutants decomposition and nitrification process.The average NH+ 4-N concentration was reduced from 33.20mg/L to 5.33mg/L.Organic matter removal also proved to be good,which reached the average 68.66%.The result showed the system had considerable capacity for both organic matter and nutrients.CSW as a low-cost media was demonstrated to be a promising substrate in constructed wetland system.More importantly,it indicated a novel reuse of CSW as medium of constructed wetland system,which provided a win-win approach to both CSW disposal and wastewater control.
