Manufacturing Method of Waster Compound Stony Pellet for removing nitrogen and phosphorus, Using of Wasted sludge

摘要

The present invention relates to a method for producing nitrogen and phosphorus removal adsorbent using sludge, and more particularly, to a method for preparing nitrogen and phosphorus removal adsorbent using waste synthetic resin and sludge.;An object of the present invention is to provide a method for producing an adsorbent for removing nitrogen and phosphorus using waste synthetic resin and sludge generated after water treatment or sludge generated after sewage treatment.;The method for preparing the adsorbent for removing nitrogen and phosphorus of the present invention comprises the steps of melting after mixing 60 to 90% by weight of waste synthetic resin and 10 to 40% by weight of sludge;;Adding foaming agent to 2.0 weight% to 6.0 weight% with respect to 100 weight% of the mixture of waste synthetic resin and sludge, followed by mixing and foaming;;Extruding the mixture of foamed waste synthetic resin and sludge in the previous step.
