Medical waste, also known as medical waste, refers to the waste generated in the process of human or animal immunization diagnosis and treatment, related research, preparation or testing of biological products, including all wastes discharged by medical and health-related units such as hospital outpatient service, health and epidemic prevention, health care and inspection. The State Environmental Protection Bureau, the State Economic and Trade Commission, the Ministry of Foreign Trade and Economic Cooperation and the Ministry of Public Security promulgated the National Hazardous Waste List [1998] No.089 on June 4, 1998, which clearly pointed out that medical waste belongs to hazardous waste. The State Council, the Ministry of Health and the State Environmental Protection Administration have successively promulgated the Regulations on the Management of Medical Wastes, Measures for the Management of Medical Wastes in Medical and Health Institutions, Measures for the Administrative Punishment of Medical Wastes Management, Measures for the Management of Hazardous Wastes, and Technical Policies for the Prevention and Control of Hazardous Wastes, which require strict management of medical wastes. Implement the declaration and registration system, the joint single transfer system and the licensing system to solve the environmental pollution caused by improper management and disposal of medical wastes.
Chapter IX Medical Waste Treatment and Disposal Technology
The treatment and disposal technologies of medical wastes mainly include incineration, autoclaving, plasma, microwave radiation, pulverization, autoclaving and chemical disinfection. Among them, incineration is the most common harmless treatment method of medical waste. Document No.57 issued by the State Council 1986 clearly stipulates: "Hospital garbage and toxic and hazardous wastes generated by other units must be collected, transported and burned separately." Article 9. 1 of the Technical Policy for Prevention and Control of Hazardous Waste Pollution promulgated by the State Environmental Protection Administration, the State Economic and Trade Commission and the Ministry of Science and Technology in 20065438 clearly stipulates that hospitals should build special incineration facilities for medical waste disposal, and it is forbidden to recycle disposable medical instruments and dressings. In 2003, the Ministry of Health promulgated the Detailed Rules for the Management of Medical Wastes in Medical and Health Institutions, which also stipulated that "those that can be incinerated should be incinerated in time". In the same year, the State Environmental Protection Administration, the General Administration of Quality Supervision, Inspection and Quarantine and the National Development and Reform Commission jointly issued GB 192 18—2003 "Technical Requirements for Medical Waste Incinerators (for Trial Implementation)" to standardize the implementation of medical waste incineration. Chapter X Medical Waste Incinerator
In an ideal state, after medical waste enters the incinerator, it goes through three stages in turn: drying, pyrolysis and combustion, in which organic combustible substances are completely burned at high temperature to generate carbon dioxide gas and release heat. The main technical factors affecting medical waste incineration include: the nature of medical waste, residence time, temperature, turbulence, air excess coefficient, etc. Among them, residence time, temperature and turbulence are called "3T" elements, which are the main indicators reflecting the performance of incinerators and are also the focus of research and development of incinerators and flue gas purification systems. The working process of the garbage pyrolysis incinerator developed by Sichuan Great Wall Institute of Environmental Science and Engineering is that the garbage enters the garbage drying and pyrolysis chamber from the garbage inlet for drying, and then enters the garbage combustion chamber for combustion after being stirred, crushed and ground by the rotating furnace plate, generating rising hot air, and the coarse dust particles contained in it are thrown on the inner wall of the upper furnace and the solid garbage moving against the current, so that the garbage is dried again and finally falls into the combustion chamber for combustion repeatedly. At the same time, the flue gas (fine dust) after oxygen-deficient combustion in the combustion chamber passes through the purification system, and the purified flue gas enters the mixing chamber through the gas collection chamber to be mixed with air and then enters the flue gas combustion chamber for complete combustion. Preheated air can also be sprayed into the chimney at the exit of the flue gas combustion chamber to produce spontaneous combustion and fully burn and crack. The tail gas is discharged from the high-altitude chimney through the micro-negative pressure generated by the ejector. The filter belt mainly relies on inertial collision, direct interception, diffusion, gravity settlement and electrostatic attraction to obtain dust removal and purification. At the same time, the polluted filter material after dust removal slowly falls into the umbrella screen for cleaning according to the adjustment speed, and the clean filter material is sent to the filter belt through the conveying device outside the furnace or manually, so that the filter material can be recycled.
