With the development of urban construction and the improvement of people's living standards, urban sanitation has also been greatly improved, which provides people with a better and better living environment. At present, the technology of urban garbage collection, transportation and treatment is still in the initial stage of development, and a large amount of domestic garbage is produced, mostly through garbage cans or garbage bins. Garbage buckets are stored centrally and then transported and dumped by garbage trucks. The above garbage disposal methods are far from meeting the needs of urban construction, management and environmental protection. There are the following shortcomings:
1. The garbage-bin and garbage hopper in residential area are open and small in volume. If the garbage is not cleaned up in time, the garbage will spill out from the garbage bin or garbage hopper, and the odor will be scattered, causing environmental pollution, increasing the workload of the cleaner and the difficulty of cleaning up.
2. Most of the garbage trucks used nowadays are open-ended. The garbage dumped is uncompressed, and the storage capacity is limited, the transportation volume is small, and the transportation cost is high. In the process of garbage transportation, the garbage blows with the wind, the odor spreads, and the garbage is polluted again.
3. Fixed garbage facilities occupy a large area and have high capital and personnel costs.
4. In the process of garbage disposal, staff members do not have safety and health protection facilities, harmful gases and bacterial contamination caused by garbage storage for a long time will endanger staff members and their surrounding areas.
