Application of Cement on the Advanced Treament of TN in Landfill Leachate Treated by Biological Processes
Through the fungicide selection,the cement shows the best result for removing TN in landfill leachate treated by biological processes on its capability of surface adsorption and hydration reaction.In lab scale,the removal rate of TN can reach 55%.Lower ratio of water/cement led to lower removal rate of TN.The treatment effect of high water cement ratio can be improved to some degree by adding Fe2O3、MgO and polymerized silicate containing magnesium salt,even in a low ratio of water/cement.
