Calcium chloride modified biochar material and preparation method and application thereof

Abstract

The application provides a calcium chloride modified biochar material and a preparation method and application thereof, and belongs to the technical field of wastewater treatment.The preparation method of the calcium chloride modified biochar material provided by the application comprises the following steps: after sunflower flower discs, fly ash and calcium chloride are uniformly mixed, granulation is performed to obtain granular biochar raw materials; after the granular biochar raw materials are subjected to aging treatment, calcination is performed at 500 DEG C to 700 DEG C to obtain calcium chloride modified biochar.The calcium chloride modified biochar material prepared by the application has the advantages of large particles, easy separation from water bodies, excellent adsorption performance, and can be used for buffering the pH of acid mine water and treating iron and sulfate ions in water bodies.
