Current situation of domestic waste

With the development of economy and the improvement of people's living standard, the problem of garbage is becoming increasingly prominent. Two thirds of 668 cities in China are surrounded by garbage. These garbage can not be buried and burned, causing a series of serious harm.

At present, the cumulative storage of domestic waste in China is more than 6.5 billion tons, occupying about 3.5 billion square meters of land. Among more than 660 cities in China, 2 / 3 of the large and medium-sized cities are surrounded by garbage, and 1 / 4 of the cities are forced to extend the solution to the garbage crisis to rural areas, resulting in secondary pollution of garbage and rapid deterioration of the ecological environment in urban-rural areas.

According to the characteristics of domestic waste in different regions of China, our company has developed new treatment equipment, which can separate waste plastics, paper, fabric, ceramics, glass and organic materials from waste, reduce the volume of garbage and expand the land use area.

Due to the complexity of domestic waste, it has become a headache in the industry. Due to the lack of domestic domestic waste classification awareness, the follow-up treatment is very complex, and there are too few recyclable materials. After years of experience accumulation, our company has gradually developed and improved a set of comprehensive and resource-based treatment solutions for domestic waste.

Overview of domestic waste scheme

Domestic waste screened by broken bags, broken materials and artificial materials The materials passing through the roller screen are sorted out according to the size. The materials on the roller screen are generally large plastic bottles and cans, which can be used for cleaning organic matters and granulation. The materials under the screen are treated by the star disc screen. The sieve residues containing moisture and fine sand can be used for anaerobic fermentation and landfill. The materials on the screen are sorted out by eddy current to sort out non-ferrous metals (non-ferrous metals) Metals have high recycling value), and if the waste containing non-ferrous metals is directly landfilled or burned, dioxins and other carcinogens will be produced; Non ferrous metal materials are sorted by positive and negative wind pressure of air separator, and light materials such as film, plastic and fabric are selected and then dried. They can be used as RDF and sent to waste incineration power plant for power generation. The materials under the screen of air separator are usually heavy objects, among which stones and tiles can be used as building aggregate.
