Technology for treatment and comprehensive use of cadmium-containing wastewater and residues

The research team has worked out two plans for the treatment of Cadmium-containing wastewater. One is the compound function agents developed to treat cadmium-containing wastewater, which means the water after the treatment can meet the drinking water standards and can be used in the deeper treatment of wastewater to realize the reuse of reclaimed water. Second is the microwave chemical treatment technology. After being treated in this way, the wastewater containing high cadmium will exceed national wastewater discharge standards with desirable indexes of heavy metals in the effluent. In the study of treatment of cadmium-containing residues, cadmium can be filtered from the residues by using aboriginal microbial, with the left residues treated as general solid waste.
