Garbage disposal process

Abstract

The invention belongs to the technical field of waste disposal and particularly provides a garbage disposal process.The garbage disposal process comprises the following steps of screening garbage, then crushing the garbage, conducting magnetic separation on the crushed garbage, picking out metal garbage, picking out sandstone and plastic garbage out of the remaining garbage through air separation, making the sandstone into building materials, and conducting crushing, washing, drying, splitting, fractionation and condensation on the plastic garbage, so that solid wax is obtained.The garbage disposal process is simple in structure, low in cost and high in efficiency, the garbage is effectively separated without being dumped or incinerated, environmental pollution is avoided, the sandstone and waste plastic obtained through separation are effectively recycled, and the waste materials are changed into things of value.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a waste treatment process. Background technique [0002] With the acceleration of urbanization and the increase of population, the output of garbage has increased sharply. At present, the annual output of urban garbage in my country is about 180 million tons. It is predicted that by 2030, the total annual output of urban garbage in China will reach 409 million tons. Among many large and medium-sized cities, 2 / 3 are surrounded by garbage, and 1 / 4 of the cities have no suitable places to pile up garbage. In our country, garbage disposal has become a thorny issue in urban construction and management. [0003] Most domestic wastes are treated by incineration. Since domestic wastes contain a variety of organic substances, the smoke from incineration pollutes the atmosphere and is harmful to humans and crops. Garbage contains a variety of substances such as plastic...

Problems solved by technology

[0003] Most domestic wastes are treated by incineration. Since domestic wastes contain a variety of organic substances, the smoke from incineration pollutes the air and is harmful to humans and crops. Garbage contains a variety of substances such as plastics, which cannot be degraded in the soil for a long time, causing pollution to the soil; then, the classification of domestic waste is mainly done manually, and the large materials such as plastics, paper, and metals in domestic waste are treated manually. Sieve, recycle and reuse

It can be seen that the existing garbage disposal methods are not conducive to environmental protection and pollute the living environment, and the plastic materials in the garbage cannot be fully utilized, the waste recycling rate is low, and the garbage sorting effect is poor.
