Abstract

The invention discloses a metal-containing hazardous waste treatment process. The method comprises the following steps: crushing metal-containing hazardous wastes, feeding into sterilization equipment for high-temperature sterilization, cooling to room temperature, soaking in sterilization liquid for 1-5 hours, passing through a magnetic separator through a conveying belt, separating metal, briquetting, and feeding a raw material for subsequent metal extraction into a power plant after airing the remaining material of the conveying belt to serve as a raw material for power generation. According to the method for treating the metal-containing hazardous waste, on the basis of traditional high-temperature rotary cutting, the step of soaking with the sterilizing liquid is added, so that the probability that the treated hazardous waste contains pathogenic bacteria is lower, and the hazardous waste is safer; the sterilization extracting solution adopts a compound sterilization solution of a dandelion extracting solution and a schefflera octophylla extracting solution, the sterilization effect is better, and the combined use synergistic interaction is realized.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of medical waste, and in particular relates to a treatment process for metal-containing hazardous waste. Background technique [0002] Medical waste belongs to hazardous waste. To deal with medical waste, the waste is generally shredded first, then sterilized at high temperature, and treated as harmless waste, and then completely disposed of by incineration, landfill or other methods. Medical waste is divided into five types: infectious waste, pathological waste, traumatic waste, pharmaceutical waste, and chemical waste. High-temperature sterilization of waste is the key to harmless treatment. In the past treatment practice, there was often a problem that the dead corners of medical devices were completely sterilized, resulting in the leakage of germs into the environment. [0003] Medical waste can be divided into plastic materials and metal materials according to the material. Metal ...
