Background technology
The processing of Biohazard Waste at present mainly contains two kinds of methods: the one, and concentrate and burn, the 2nd, concentrate and bury.These two kinds of methods have with lower drawback:
1, serious environment pollution.If Biohazard Waste adopts the method for burning, can produce a large amount of dioxime English and carbon dioxide, contaminated air, impel climate warming; If adopt the method for burying, can waste very much land resource, contaminated environment.
2, undressed Biohazard Waste easily causes secondary pollution in storage and transportation.No matter be to concentrate burn or concentrate and bury, all need that Biohazard Waste is transported to concentrated area from medical institutions such as hospitals and processed.And germ, virus can carry out in transit disseminate, bring potential secondary pollution risk.
3, the plasthetics such as woven hose, needle tubing, plastic gloves, refuse bag are arranged in Biohazard Waste, syringe needle is arranged, the metallic articles such as knife blade, have vial, and the glasswares such as glass needle tubing also have the cotton goods such as bandage, gauze, cotton thread.Burning and the method for burying have been ignored a large amount of plastic cement, metal, and the material of the recyclable recycling such as glass, wasted natural resources.
