Hazardous waste disposal manufacturers believe that with the rapid development of economic and industrialization, solid waste pollution problems are becoming increasingly prominent, threatening the environmental security of human existence. Solid waste mainly includes domestic waste (including food waste, etc.), general industrial waste (including urban sludge, etc.), hazardous waste (including medical waste), radioactive waste, etc.. Among them, hazardous waste is widely concerned because of its special hazards to human body and environment.

　　Hazardous waste disposal manufacturers believe that the purpose of solid waste treatment is to achieve resourcefulness, minimization and harmlessness. Compared with foreign developed countries, China's hazardous waste disposal technology started late and developed slowly, and is trying to catch up with foreign countries. At present, China's hazardous waste disposal projects using technologies such as comprehensive utilization (resource utilization), physical, chemical, biological methods, solidification, incineration, safe landfills, and new cement kiln co-disposal, plasma melting. At present, the pattern of hazardous waste disposal in China is mainly divided into state-built large centralized disposal centers (mainly comprehensive utilization, landfills and incineration), local construction of relatively small centralized disposal facilities (mainly landfills and incineration), the state supports and encourages enterprises to build their own disposal facilities free of charge (can provide some social services).

　　Hazardous waste disposal manufacturers believe that the comprehensive utilization of technology can be divided into energy replacement technology, physical and chemical treatment technology, material separation and recovery technology, material recovery and land restoration technology. At present, the comprehensive utilization of hazardous waste in China is mainly focused on the recycling of metals, waste organic solvents, waste acids and bases, waste oils, electronic waste, etc.. The main use of physical and chemical treatment technology and material separation and recovery technology. The advantage of comprehensive utilization of hazardous waste is resource recycling, the disadvantage is that the price of resource products fluctuates greatly, the profit margin is not high, and the domestic comprehensive utilization technology is relatively rough. The regeneration process may bring secondary pollution.

　　Hazardous waste disposal manufacturers believe that physical treatment is to change the structure of hazardous waste through concentration or phase change, so that it is easy to transport, storage, use or further disposal. Physical treatment methods are mainly adsorption, compaction, comminution, sorting, extraction, solid-liquid separation, dialysis, cooling crystallization, reverse osmosis, air blow-off, etc.. After physical treatment of hazardous waste, the volume of hazardous waste can be greatly reduced and is suitable for the treatment of sludge, industrial sludge and other wastes with high water content.

　　Hazardous waste disposal manufacturers believe that chemical treatment is the use of chemical methods to destroy the hazardous components in hazardous waste. Its purpose is to change the chemical properties of the treated material, reduce its hazardousness and transform it into a form suitable for further treatment and disposal. Chemical treatment is the main pretreatment method for hazardous wastes before they enter the disposal phase. It is usually used to treat inorganic wastes. Such as waste acids and bases, waste liquids containing heavy metals, waste liquids containing qingides, emulsified oils, etc. Common treatment methods include acid-base neutralization, redox, flocculation precipitation, etc.
