The Experimental Study of Contaminant Removal in Water Quenched Slag Biological Aerated Filter (BAF)

Abstract:

In order to effectively resolve pollution issue of water quenched slag and its comprehensive use or second use of materials, the water quenched slag filter material is developed using water quenched slag with the addition of adhesion-increasing agent and porogen by commingle, pelletizing and curing. Experimental results indicate that water quenched slag filter material is used as filter medium in biological aerated filter for wastewater treatment,and the removal rate of COD, NH3-N comes up to 84.62%,90.20% respectively. The filter material is much more predominant and possesses a much wider application prospect in the treatment of wastewate.
