What is the best and most practical method for selecting a waste? Such as waste composition, nature, status, climatic conditions, safety standards, disposal costs, operation and maintenance and other conditions. Although many methods can be successfully applied to the treatment of hazardous wastes, the commonly used treatment methods are still summarized as physical treatment, chemical treatment, biological treatment, heat treatment and curing treatment. 1. Physical treatment: Physical treatment is to change the structure of solid waste through concentration or phase change? To make it easy to transport, storage, use or disposal of the form, including compaction, crushing, sorting, thickening, adsorption, extraction and other methods. 2. Chemical treatment: Chemical treatment is the use of chemical methods to destroy harmful components in solid waste, so as to achieve harmlessness, or transform it into a form suitable for further processing and disposal. Its purpose is to change the chemical nature of the treated substance so as to reduce its harmfulness. This is a commonly used pretreatment measure before the final disposal of hazardous wastes. The treatment equipment is conventional chemical equipment. 3. Biological treatment: Biological treatment is the use of microorganisms to decompose degradable organic matter in solid waste, so as to achieve harmless or comprehensive utilization. Biological treatment methods include aerobic treatment, anaerobic treatment, and facultative anaerobic treatment. Compared with chemical treatment methods, biological treatment is generally cheaper economically? Application common? However, the processing time required is long and the processing efficiency is not stable enough. 4. Heat treatment: Heat treatment is to destroy and change the composition and structure of solid wastes through high temperature, and at the same time achieve the purpose of volume reduction, harmlessness or comprehensive utilization. The methods include incineration, pyrolysis, wet oxidation, calcination and sintering. Wastes with high calorific value or high toxicity adopt incineration treatment process for harmless treatment, and waste incineration wastes are recovered for comprehensive utilization and material/chemical treatment, as well as for employees' bathing and living, thereby reducing processing costs and energy waste. 5. Curing treatment: Curing treatment is the use of solidified substrates to fix or coat wastes to reduce their harm to the environment. It is a safer process for the transportation and disposal of wastes. It is mainly used for hazardous wastes and radioactive wastes. The volume of the solidified body is much larger than the volume of the original waste. 6. Various treatment methods have their advantages and disadvantages and applicability to different wastes. Due to the different components and nature of hazardous wastes? It is difficult to have a unified model. For the characteristics of each waste, a suitable treatment method can be selected.
