With the improvement of modern people's pace of life and the increase of urban population, the production and types of garbage are also increasing, and the difficulty of garbage disposal is also increasing. The most common method of waste disposal currently is landfilling, but the landfilling of raw waste brings numerous problems, such as land occupation, impact on the surrounding environment, and pollution of groundwater. In garbage, the recycling and utilization of waste glass, waste plastics, and other materials will have high value. Unclassified disposal of waste batteries can cause significant pollution to the environment. So, the comprehensive treatment and utilization of garbage become very important.

The comprehensive treatment technology of household waste is the core of achieving harmless, reduced and resourceful treatment of waste. Its main purpose is to effectively separate different types, sizes and densities of components in the waste through sorting, screening and crushing, so as to incinerate the high calorific value parts, carry out biochemical treatment containing organic matter, recycle the recyclable parts, and landfill the parts that cannot be used as resources.

The complete set of equipment for sorting household waste is a sorting system developed based on the characteristics of high humidity mixed household waste in China and the principle of maximizing recycling and resource utilization. This complete set of equipment mainly adopts garbage sorting and shredding machines and drum airflow sorting machines, greatly reducing manual sorting workload. It can effectively separate organic matter, combustible waste plastics, unbreakable metal objects, and inorganic waste in household waste into four categories. The drum screen also has bag breaking function, with a bag breaking rate of 85%. Compared with traditional process equipment, this complete set of equipment greatly saves investment, has high sorting efficiency, and achieves maximum resource utilization.

The biggest problem facing China's garbage disposal is the high moisture content of garbage. In some areas, the moisture content of garbage is even greater than 50%, making it very difficult to incinerate high moisture and low calorific value household garbage. Many waste incineration power plants place their garbage in the original garbage bin for a few days before incineration to remove some of the leachate (water) inside. During this process, it will naturally undergo an anaerobic reaction, emitting more harmful gases and increasing the cost of leachate treatment. In addition, waste incineration plants mix coal with waste incineration to increase its calorific value, which not only increases costs but also generates additional greenhouse gas emissions. Therefore, in order to improve the calorific value of garbage incineration, reduce costs, and minimize harmful gas emissions, the key is to dehydrate and dry the garbage. Due to the unsatisfactory front-end classification of garbage, most of China's household waste is mixed waste, which is very difficult to classify and process. In order to customize a scientific, reasonable, and feasible sorting process, a comprehensive analysis of basic data such as moisture content and dry matter content of household mixed waste is conducted. Select different sorting technology equipment according to the requirements of garbage treatment and disposal.
