The invention belongs to the technical field of environmental protection and resource comprehensive utilization, and provides a continuous supercritical / subcritical water oxidation solid-liquid mixture co-processing system and process. The process comprises the steps that after landfill leachate and incineration fly ash are stirred and mixed according to a set liquid-solid ratio, a uniformly-mixed material is obtained; after high-temperature and high-pressure heating oxidation treatment is carried out on the uniformly-mixed material in the presence of oxygen, a gaseous discharged material and a solid-liquid mixed discharged material are obtained; and precipitation collection is carried out on the solid-liquid mixed discharged material, gas-solid separation, cooling and gas-liquid separation are sequentially carried out on the gaseous discharged material, and corresponding product classified collection is carried out. The system comprises a stirring container, a reaction unit, a gas-solid separator, a cooler, a gas-liquid separator and a gas storage tank, the stirring container is used for stirring and mixing the landfill leachate and the incineration fly ash, the reaction unit is respectively connected with the stirring container, the gas-solid separator and the gas storage tank, and the cooler and the gas-liquid separator are sequentially connected behind the gas-solid separator. The process and the system can be used for cooperatively processing the landfill leachate and the incineration fly ash.
Description
technical field [0001] The invention belongs to the technical field of environmental protection and comprehensive utilization of resources, and specifically relates to a continuous super / subcritical water oxidation solid-liquid mixture co-processing system and process, which realizes co-treatment of landfill leachate and incineration fly ash, and is also suitable for continuous synergy Treat liquid waste with high organic content and solid waste containing heavy metals and dioxins. Background technique [0002] Waste incineration power generation technology can realize the reduction, recycling and harmless treatment and disposal of domestic waste. After more than 100 years of development, its processing technology and technology have become increasingly mature, and it has become the main method of global waste disposal. However, the harmless treatment and disposal of landfill leachate and incineration fly ash produced in the process of waste incineration for power generation...
