Novel technology for treating organic wastewater through industrial residue manganese dioxide

The invention relates to a novel technology for treating organic wastewater through industrial residue manganese dioxide and belongs to the technical field of organic wastewater treatment. According to the novel technology disclosed by the invention, manganese dioxide waste residues from industrial production is sequentially washed and filtered by tap water, washed by a 50% saltpeter solution, washed by tap water to a neutral state and washed by industrial alcohol to obtain refined manganese dioxide; then the refined manganese dioxide is heated in a muffle furnace under 200 to 400 DEG C for 3to 5 h to obtain activated manganese dioxide; then the activated manganese dioxide and activated carbon are added into the organic wastewater to be stirred under 20 to 100 DEG C for 0.5 to 2 h; a clarified and transparent solution can be obtained after filtering. According to the novel technology disclosed by the invention, the raw materials have wide sources, the activating treatment step is simple and convenient to oper
