AI Technical Summary

Problems solved by technology

The problems of incineration and burial are as follows: incineration: the investment in the initial construction of the plant is large, resulting in secondary pollution; incineration produces dioxin and cancer control materials; the waste generated by incineration has to be buried; only investment without return
Burial: Pollution of groundwater, causing serious secondary pollution; large initial investment in building a landfill plant; occupying a large amount of land; only investment without return

Embodiment Construction

[0018] The method will be described in detail below with specific examples.

[0019] Beijing hospital waste treatment plant, the daily processing 50 tons of hospital waste plants set up by the inventive method:

[0020] 1. Process method

[0021] The first is to steam oxygen for sterilization and disinfection; the hospital garbage is transported to the garbage factory in a special closed car, measured by an electronic scale and unloaded into a special warehouse, and then operated on a closed conveyor belt to steam oxygen in a high-pressure oxygen steam kettle, the steam temperature is greater than 210 °C, and the steam pressure The pressure is 12 atmospheres, and the oxygen evaporation time is 3 hours.

[0022] After the hospital waste is steamed with oxygen, the sterilization rate of various bacteria and viruses has reached 100%.

[0023] Second, explosion sterilization

[0024] In the high-pressure and high-temperature sterilization, in order to prevent special bacteria a...

Abstract

A method for reclaining the hospital refuse without any damage to environment features that the high temp, high pressure, explosion, magnetizing and biologic fermenting are used to treat the hospital refuse. The organic substance in treated refuse is used as organic fertilizer and the inorganic material is used to prepare building material, plastics, rubber, chemical fibres and fuel oil.

Description

technical field [0001] The invention relates to the field of harmless and resourceful treatment of hospital garbage. Background technique [0002] Hospital waste is the most difficult type of waste to deal with, and it is also the most concentrated breeding ground for germs and viruses. Its harm is great, serious, and deep, and we must pay attention to it. The harm of hospital waste has attracted great attention from the scientific community and governments at all levels. In order to completely, cleanly and harmlessly dispose of hospital waste, many scientists are working tirelessly to study ways and methods of control and control. Governments at all levels are constantly issuing red-headed documents and adopting various methods to dispose of hospital waste. But so far, hospital waste is still in the stage of incineration. As far as incineration is concerned, it has just emerged in megacities. Most of the hospital waste is mixed with domestic waste and discarded. In many sm...
