Abstract

This article presents the experimental studies results of the filtering drainage wastewater purification of solid waste landfills with modified reagent solutions. Experimental studies were conducted at solid waste landfills in Ukrainian cities. Modification of the coagulant solution was conducted in a special device, which provides for the creation of ionic associates resulting from magnetic treatment and their fixation with anodically dissolved iron. The effect of the modified coagulant solution was substantiated theoretically at the wastewater treatment process. The effect of the modified coagulant solution was studied to the granular medium protective effect increase and the time of the limiting head losses reach at rapid filters during the filtrate tertiary treatment of solid waste landfills. It was found that the modified coagulant solution use makes it possible to intensify the processes of wastewater treatment in solid waste landfills by an average of 25–30%. The dependence of predicting the changes in biochemical oxygen demand of treated wastewater was proposed to confirm the technological procedure for the filtration wastewater purification from solid waste landfills using a modified coagulant solution and biodisks.
