Carbon source for wastewater treatment manufactured using organic solid waste

Abstract

The application discloses sewage treatment carbon source manufactured by organic solid waste, and relates to the technical field of sewage treatment, which comprises a cross-linking complex manufactured by organic solid waste, wherein the cross-linking complex comprises a cross-linking carrier and a multi-layer functional medium arranged on the cross-linking carrier, and the multi-layer functional medium comprises a fine matrix layer, a coarse matrix layer and a biochar adsorption body in sequence; and the cross-linking carrier is obtained by heat cross-linking of waste plastics. The fine matrix layer can be directly absorbed by bacteria, so that the initial carbon release speed of the added carbon source is improved; with the denitrification, the microorganisms are continuously increased; after the cross-linking complex and the fine matrix layer are degraded and consumed, the coarse matrix layer is gradually exposed; the cross-linking carrier and the coarse matrix layer manufactured by the organic solid waste can continuously supplement the carbon source and slowly release the carbon source; when the growth cycle of the bacteria is over, the last biochar adsorption body can adsorb the bacteria corpses in water, so that the impurities in the sewage are reduced.
