With the cause of national health development and the continuous improvement of the level of health requirements in recent years, the amount of medical waste generation in China has increased year by year, the disposal of medical waste has attracted more and more attention. In view of the infectious medical waste and toxicity, as well as volume reduction, weight loss, safe handling requirements, a variety of treatment methods in medical waste pyrolysis - incineration is considered the best approach. At present, China's medical waste physical and chemical properties database is not perfect, incineration technology is not yet mature. Based on this research background, this paper carried out the medical waste materialized pyrolytic incineration characteristics of basic research, and to provide valuable references for the latter part of research work. The physical and chemical properties of the medical waste from the production of medical waste, bulk density, physical composition and C1, F content. Different hospitals, physical components of their medical waste, hospital size and type of the physical components of the medical waste, the initial establishment of the physical and chemical characteristics of the database of medical waste, medical waste, as well as the selection of medical supplies medical waste collection and processing of data and the theoretical basis. Applications TGA FTIR method, typical components of medical waste pyrolysis, incineration conditions Thermogravimetric characteristics and gas production characteristics. Specifically containing PVC plastic, analysis of the atmosphere, the component, gas flow, heating rate and other factors. A deeper understanding of the pyrolysis of medical waste incineration characteristics. Pyrolysis - incineration test of a single-component, two-component, and medical waste chlorine content of medical waste component, the chlorine content of PCDD / Fs distribution characteristics. Through the distribution characteristics of PCDD / Fs analysis, found that different chlorine content in plastic to generate PCDD / Fs and chlorinated levels are different. Fiber of PVC incineration generates of PCDD / Fs role in promoting, and its chloro level to improve, and this effect is different for different PVC. With increasing chlorine content, six, seven, eight-chlorinated furans production tended to increase, of dioxins production changes associated chlorine content is not obvious, but when the chlorine content increases to 1.73%, its production improved significantly. Medical waste it generates the same chlorine content of PVC chlorine source PCDD / Fs different characteristics.
