The amount of construction waste accounts for 30-40% of the total urban domestic waste in my country. Calculated on the basis of 500-600 tons per 10,000 square meters, as of 2021, my country will have an additional construction area of ​​30 billion square meters, and the amount of construction waste generated will be a very shocking figure. Although the problem of environmental pollution caused by construction waste is very serious, China still does not pay attention to the reuse of construction waste. In fact, construction waste can be recycled and reused through effective management.

At this stage, the international trend of garbage disposal is "comprehensive waste management", which means that all people are encouraged to participate in actions to reduce the amount of garbage generated. The action slogan is: (1) reduce waste; (2) make best use of materials; (3) recycle. When consumers in the whole society do this, the total output of domestic garbage and the burden of garbage disposal in urban areas will be greatly reduced, and the life of the landfill will increase. Thereby saving land resources and reducing the harm of environmental pollution.

Manufacturers specializing in the research of construction MSW sorting equipment mainly use "screening and sorting" as the main core technology. According to the different production needs of customers, they adopt customized and personalized equipment, very flexible management methods, and intelligent The main direction of production is to focus on the production needs of customers, and the production process is very intelligent through the advancement of information technology, and the rapid production and delivery of equipment is ensured.

The research on construction waste treatment technology makes full use of the core competitiveness of screening and sorting technology, and the core is around the eight characters of "intelligence, efficiency, energy saving, and environmental protection", providing various construction waste under the circular economy project. A complete set of technical treatment programs and a complete set of garbage sorting equipment.

In the face of various problems arising from garbage sorting, the following points should be done to enhance people's awareness of garbage sorting. my country has just implemented garbage classification in recent years. For the masses, garbage classification is still a relatively new term, and there is not much knowledge about garbage classification. In the face of this situation, it is necessary to increase the promotion of garbage classification. For example, publicity pages are posted in shopping malls, universities and other areas with high traffic, and garbage classification is carried out through media, newspapers, TV and other channels, and push methods such as the Internet, Weibo, and WeChat public accounts.

With the updating and upgrading of technologies such as the Internet of Things and artificial intelligence, the assistance of intelligent waste sorting equipment is of course inevitable in the links of waste sorting and supervision and management. Citizens use intelligent waste sorting machine to intelligently identify the types of waste, and the waste treatment plant can also intelligently sort recyclable items, and then conduct statistical analysis of data to intelligently monitor the actual status of waste sorting.

Take local treatment or centralized fertilizer. Other garbage is treated as sanitary landfill.

Waste disposal after classification:

(1) Wet waste (organic waste) is processed into organic fertilizer or organic compound fertilizer in the full utilization of organic waste production and processing plant for landscaping or fertilizer for agriculture and animal husbandry.

(2) Dry waste (inorganic waste) is further refined and classified into recyclable components such as waste paper, waste plastic, waste glass, and waste metal in the domestic waste sorting base, and then the corresponding recycling plant Take recycling.

(3) Hazardous garbage is sorted at the hazardous garbage sorting and treatment station, the recyclables are sent for reuse, and the residue is treated by incineration or safe landfill.

The current trend of garbage sorting in many urban areas is through the use of intelligent garbage sorting equipment and modern information technology to complete the promotion of garbage classification, garbage sorting and delivery, garbage sorting collection, garbage sorting and transportation, garbage Intelligent management is adopted in the whole garbage disposal process such as sorting, making the sorting of garbage simpler and more intelligent, and promoting the purpose of recycling urban domestic waste.
