Description
Technical Field
The application relates to the technical field of waste plastic treatment, in particular to production equipment for waste plastic and sludge treatment.
Background
The plastic industry in China is one of the prop industries of national economy and has entered the world's plastic world wide line. Most of the plastics currently used are produced from petrochemical products, of which about 75% are petroleum-based plastics and about 20% of recycled plastics are also substantially recycled from petroleum-based plastics.
At present, the plastic waste treatment method mainly comprises three methods of high-temperature incineration, landfill and recycling. A large amount of harmful gas is released during waste incineration treatment, and secondary pollution is generated; the land filling needs to occupy a large amount of arable land area, which can aggravate the crisis of land resource shortage, and meanwhile, a large amount of waste is placed underground, so that the contact between the waste and the sunlight and the air is cut off, and the degradation is more difficult; recycling of disposable plastic products, mulching films, etc., which are difficult to separate, is economically or practically difficult.
Under the current situation of rapid development of urbanization construction, the overall production amount of sludge is increasing, which is one of the main problems faced by the current sewage treatment plant. At present, the sludge treatment comprises the methods of sanitary landfill, anaerobic digestion, aerobic fermentation, drying incineration and the like. The landfill capacity of sanitary landfill is limited, the sludge percolate easily causes secondary pollution, the case that the landfill site refuses to accept the sludge is not fresh in recent years, and the disposal mode of the landfill is abandoned gradually; anaerobic digestion is the most widely applied sludge stabilization and resource method internationally at present, but the sludge in China has the problems of poor biodegradability, long system treatment time, high sewage purification cost and the like, so the anaerobic digestion is supposed to be 'water and soil unappealing'; the greatest limitations of aerobic fermentation are that the fertilizer has large production amount, low nutrient content, easy soil hardening after long-term use, low fertilizer efficiency, no application in agriculture and no market selling of the fertilizer; the drying incineration is a conventional method for treating sludge in China, the method dehydrates the sludge to about 40 percent, and the dehydrated sludge is mixed with a certain amount of auxiliary fuel for burning, but the energy utilization value is not high, the sludge needs to be paid for treatment when being transported to an incineration plant, if the sludge is subjected to synergistic treatment by a cement kiln, the operation cost is higher, and the treatment amount is influenced by the sales volume of the cement.
With the gradual depletion of fossil fuels, the replacement of fossil energy becomes an important research topic in the field of new energy development. The resource utilization of waste plastics and sludge can not only reduce the treatment cost of garbage, but also can produce useful energy or resources, and has important significance for the construction of 'non-waste cities' and the sustainable development of economy and society, therefore, the utility model provides a production facility for waste plastics and sludge treatment in coordination.
