Chemical disinfection harmless treatment technology for medical waste

Abstract

The invention belongs to the technical field of waste treatment and provides a chemical disinfection harmless treatment technology for medical waste. The chemical disinfection harmless treatment technology for the medical waste comprises smashing treatment and disinfection treatment of the medical waste and comprises the steps that the medical waste is collected and transported through transportation vehicles, the medical waste conveyed by a conveyer belt is shifted to a lifting frame of an overturning feeding device to be lifted and fed through a circulation box; the medical waste is fed into a mixing feeding hopper through the lifting frame, and meanwhile radioactivity detection is conducted on the medical waste; the medical waste is processed into medical waste residues through fine smashing, and PH value monitoring is conducted when second-grade fine smashing is conducted; and finally, the medical waste residues are transported through dedicated vehicles to a waste plant for incineration treatment. The chemical disinfection harmless treatment technology for the medical waste comprises smashing treatment and disinfection treatment of the medical waste has the advantages of being low in investment, low in operation expense, less in pollutant discharge, high in automatic control level and the like. The chemical disinfection harmless treatment technology for the medical waste is high in automation degree, greatly lowers the treatment cost of the medical waste, solves the medical waste treatment problem of Ningbo City and has good application and popularization value in the industry.

Description

technical field [0001] The invention belongs to the technical field of waste disposal, and in particular relates to a chemical disinfection and harmless disposal process of medical waste. Background technique [0002] Medical waste is included in the National Hazardous Waste List and must be disposed of in accordance with hazardous waste disposal regulations. Medical waste without disinfection pretreatment is not allowed to be directly landfilled. The common disposal methods of medical waste include chemical disinfection, high temperature incineration, plasma method, high temperature sterilization, electromagnetic wave sterilization, etc., which have always been difficult in the field of environmental protection disposal, and direct incineration of medical waste treatment is the most important domestic medical waste treatment method. The main disposal method, but due to the high requirements for environmental protection disposal of incineration products, the cost of treatmen...

AI Technical Summary

Problems solved by technology

The common disposal methods of medical waste include chemical disinfection, high temperature incineration, plasma method, high temperature sterilization, electromagnetic wave sterilization, etc., which have always been difficult in the field of environmental protection disposal. The main disposal method, but due to the high requirements for environmental protection disposal of incineration products, the cost of treatment equipment is also high

In addition, dedicated medical waste incineration has disadvantages such as small plant scale, relatively scattered layout, low equipment operation rate, and high treatment costs, and increases the risk of pollution and control
