With the improvement of modern people's pace of life and the increase of urban population, the output and types of garbage are increasing, and the difficulty of garbage disposal is becoming more and more difficult. At present, the most common way of garbage disposal is landfill, but the landfill of raw garbage brings many problems, such as: land occupation, impact on the surrounding environment, pollution of groundwater, etc. Among the garbage, the recycling of waste glass, waste plastic, etc. will have a higher value. If waste batteries are not sorted and treated, it will cause great pollution to the environment. Therefore, the comprehensive treatment and utilization of garbage by garbage sorting equipment is very important.

The comprehensive treatment technology of domestic garbage is the core of realizing the harmless, reduced and resource-based treatment of garbage. Its main purpose is to effectively separate the components of different types, sizes and specific gravity in the garbage through sorting, screening and crushing, so as to achieve incineration of the high calorific value part, biochemical treatment of organic matter, recycling of recyclable parts, and landfill of non-resource-based parts.

The complete set of domestic waste sorting equipment is a sorting system developed based on the principle of maximizing recycling and resource utilization for the characteristics of high-humidity mixed domestic waste. This process complete set of equipment mainly adopts garbage sorting shredder and drum airflow sorting machine, which greatly reduces the workload of manual sorting, and can effectively separate organic matter, combustible waste plastic, unbreakable metal and inorganic waste in domestic waste into four categories. The drum screen also has a bag breaking function, and the bag breaking rate reaches 85%. Compared with traditional process equipment, this complete set of equipment greatly saves investment, has high sorting efficiency, and realizes resource utilization to the greatest extent.

The biggest problem facing garbage disposal is the high water content of garbage. In some areas, the water content of garbage is even greater than 50%. It is very difficult to incinerate domestic garbage with high moisture and low calorific value. Many garbage incineration power plants keep garbage in the original garbage warehouse for a few days before incineration to remove some leachate (water) inside. In this process, it will naturally undergo an anaerobic reaction process, emit more harmful gases, and increase the cost of leachate treatment. In addition, in order to increase the calorific value of garbage incineration, waste incineration plants will mix coal with garbage for incineration, which not only increases costs, but also produces additional greenhouse gas emissions. Therefore, in order to increase the calorific value of garbage incineration, reduce costs, and reduce harmful gas emissions, the key is to dehydrate the garbage. Due to the unsatisfactory front-end classification of garbage, domestic garbage in my country is basically mixed garbage, 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 the moisture content and dry matter content of domestic mixed garbage is conducted. Different sorting technology equipment is selected according to the requirements of garbage treatment and disposal.
