Description
Technical Field
The invention belongs to the technical field of household garbage treatment, and particularly relates to a method and equipment for recycling household garbage.
Background
With the gradual advance of industrialization and urbanization in China, the problem of municipal domestic waste is more and more concerned by people. At present, the annual production amount of urban garbage in China is close to 2 hundred million tons, the average annual production amount of garbage per person is about 300kg, and the urban garbage is basically increased at a speed of 10% in recent years. A plurality of data show that about 2/3 of large and medium-sized cities in China are surrounded by garbage, and the life quality of people is seriously influenced.
The aim of solving the garbage problem is to reduce the volume, recycle, convert and harmlessly treat the garbage. At present, the popular municipal solid waste treatment and disposal technologies mainly comprise incineration, landfill and composting, and in addition, the RDF technology, the anaerobic bio-biogas production technology and other treatment technologies also appear abroad and are applied to the treatment of municipal solid waste. In fact, the technologies are mostly extension, matching and development of incineration, landfill and composting technologies. According to the 'Chinese statistics yearbook 2015', the total amount of harmless treatment of garbage in China in 2014 reaches 16393.7 ten thousand tons, wherein the landfill amount of the garbage reaches 10744.3 ten thousand tons accounting for 65.54 percent of the total amount, the incineration treatment amount reaches 5329.9 ten thousand tons accounting for 32.51 percent of the total amount, and the garbage compost is in an atrophied state. Therefore, municipal solid waste in China is mainly treated by means of landfill and incineration. The landfill not only causes environmental impact, but also occupies a large amount of land, so that the contradiction between the municipal solid waste treatment and the land resource in the developed area is sharp. The population density indicates the shortage degree of land resources to a certain extent, the population density in east China, china and south China ranks the first three, and is far higher than that in other areas, so that the shortage of the land resources in the areas is indicated, and the large domestic garbage generation amount and the large garbage treatment pressure in the areas per unit area are indicated.
The waste incineration treatment in China starts late and is limited by economic level, so the waste incineration treatment is developed slowly for a long time. In the application process of garbage incineration in China, the investment of an incineration method is large, and the occupied capital period is long; the incineration has certain requirements on the calorific value of the garbage, generally can not be lower than 5000kJ/kg, and the application range of the garbage is limited; the problem of dioxin generated in the burning process has certain requirements on the process technology; the operation is not standard, the garbage classification is not in place, so that the smoke discharged by the garbage incineration plant can not stably meet the relevant national emission standards, a series of environmental pollution problems are generated, and the normal life of local residents is influenced.
CN104928323A discloses a biological treatment method for household garbage, which comprises coarse separation and fermentation of the separated organic garbage. The scheme requires that the domestic garbage is roughly sorted and then fermented. The garbage of our country is difficult to classify at present, and the scheme requiring screening is difficult to popularize and apply in practice.
Therefore, there is a need for a method and apparatus for treating domestic waste without sorting.
