Specification process method for urban pollutant

Abstract

The invention relates to a municipal refuse classification processing method, which comprises a plurality of steps of (1) primary separation that the garbage which can be treated solely is separated from municipal refuse, (2) primary fragmentation, (3) one-time separation that the garbage material is divided into weight material mainly comprising inorganic substances and soft material mainly comprising organic compounds, (4) crushing of weight material, (5) magnetic separation of weight material that the weight material is divided into magnetic weight material and non-magnetic weight material, and (6) crushing of soft material; wherein, the metallurgy mineral processing of magnetic weight material is processed; the separated fine mineral sand is adopted as metallurgy material; the separated mine tailing is mixed with the non-magnetic weight material and treated together; the non-magnetic weight material is applicable to architecture materials and filler; the crushed soft material is applicable to fuel, marsh gas, compost or fertilizer. The municipal refuse classification processing method has the advantages of adopting most of municipal refuse as recyclable material to classify and treat, and facilitating the resource utilization of most municipal refuses.

Description

technical field [0001] The invention relates to a garbage disposal method, in particular to a municipal garbage disposal method. Background technique [0002] Urban waste has a wide range of sources, complex components, and difficult treatment. At present, except for a small amount of materials that can be directly recycled, most of them are disposed of by landfill and incineration. However, these treatment technologies have Disadvantages that cannot be ignored, such as landfill needs to occupy a site, and can pollute groundwater and air, while incineration requires energy consumption, and its flue gas also contains harmful gases and suspended particles, which is also very difficult to treat. Due to the improvement of people's living standards and the development of urbanization, the output of urban garbage is increasing, and the continuous use of landfill and incineration will encounter great difficulties in both resource and environmental protection. Therefore, people beg...

Problems solved by technology

Therefore, people began to continuously explore the ways of resource utilization of waste materials. One of the important aspects is the classified collection and separation of waste. There are two categories of recycled garbage. After the garbage is generated, these two categories of garbage are placed in different containers for collection. The so-called recyclable garbage is mainly materials that can be directly used as industrial raw materials, such as plastics, Metal and glass, etc., the so-called non-recyclable garbage refers to other materials that cannot be directly used as industrial raw materials or materials with low value when used as industrial raw materials. Although this method has been generally approved by people, it is still used in practice. There are some problems. One is that people often do not sort garbage in order to save trouble, and the other is that this sorting method includes most of the urban waste as non-recyclable, which is of little significance in reducing the amount of landfill and incineration waste.
