Study On The High-temperature And High-pressure Steam Sterilization Of Medical Waste Treatment System And Application

Medical waste is the first category of hazardous waste pollutants in China. It is a very important task to dispose the medical waste according to the relevant laws and regulations in state.On the basis of careful analysis of medical waste in the definition and classification, the paper was studied about source, output, composition and hazards, and management. It mainly researched on the current status about the medical waste disposal and the progress of all kinds of medical waste treatment and disposal technology. The various medical waste disposals and the applicability of the main problems were summarized. The medical waste disposal center in small and medium cities uses the high-temperature and high-pressure steam sterilization process which is in line with national technical specifications and requirements related to hazardous waste disposal in China, and it has irreplaceable advantages. The paper provides a comprehensive analysis of the high-temperature and high-pressure steam sterilization process. And it researches and optimizes control parameters. The paper also summarizes the wastewater and exhaust gas treatment process and the collection, transportation management system in the related matching process. Type of high-temperature and high-pressure steam sterilization of medical waste treatment system to promote a certain practical significance. Mainly include:(1) The relationship of the temperature in sterilization pot and pressure, vacuum can be expressed as:(2) Medical waste Packaging, air exclusion, sterilization room structure and type of hot steam penetration has some impact, the ultimate impact the sterilization effect.(3) In the pressure 220KPa (gauge pressure), when the temperature is 134℃, 30min to achieve complete sterilization effect; Loading capacity is 60%, the economic benefit is best.(4) Based on the combination of adsorption and condensation process, the proposed use of membrane filter method or biological treatment.(5) The wastewater from High-temperature and high-pressure steam sterilization of medical waste after disposal has reached the first discharge standard of the Comprehensive Standard of Wastewater Discharge (GB-8978-1996) using the Regulation Pond- CASS Biochemical Pond -Disinfection Pond process.(6) The disposal system based on prop-drag container collection and multi-line transportation routes in full scope connecting with the measurement of statistical systems is effective and safe.
