Clean processingequipment of medical treatment plastic waste product
Technical Field
The invention relates to a medical waste treatment device, in particular to a cleaning and processing device for medical plastic waste.
Background
According to the regulations of the State Council of medical waste management, medical waste refers to waste which is generated by medical and health institutions in medical, preventive, health care and other related activities and has direct or indirect infectivity, toxicity and other harmfulness. With the rapid development of the economy of all countries in the world and the continuous improvement of the living standard of people, the global health cause is greatly developed, and the increase of medical waste is also extremely striking. The related data show that each bed in hospitals in China averagely generates 1000 g of waste per day, the daily medical waste of a medium city is about 40 to 70 tons, and the annual medical waste of a province is as much as 9600 tons, wherein the ratio of plastic products is very high.
The stockpiling or landfill of medical wastes not only invades the land area but also pollutes the soil environment. It is estimated that solid waste occupies about 666 ten thousand square meters per 1 thousand tons of stacked. The discharge and accumulation of large amounts of waste also destroys the landscape, vegetation and natural landscape. In the waste stacking or landfill without proper anti-leakage measures, harmful components in the waste are easy to erode and permeate into soil, and can kill microorganisms in the soil, so that the soil loses the decomposition capability and the plant growth environment is damaged.
Along with the development of national economy and the acceleration of urbanization process, the production amount of medical wastes in China is continuously increased, and the problem of harmless treatment is more concerned by people. The harmless treatment of medical wastes has important significance for preventing disease transmission, protecting ecological environment and guaranteeing human health. Traditional landfilling and incineration, both cost and environmental pollution, have limitations.
