Domestic waste disposal specifically refers to the treatment of solid waste generated from daily life or activities that provide services for daily life, as well as solid waste considered as domestic waste according to laws and regulations, including source reduction, cleaning, classified collection, storage, transportation, treatment, disposal, and related management activities of domestic waste.
Processing Purpose
1.Reduce waste production
2.Ensure proper disposal of discharged garbage
3.Realize the increase of benefits in garbage disposal
4.Promote the development of circular economy
5.Reduce or minimize garbage pollution
basic task
1.Source demand side management
2. Construction and management of garbage disposal system
3. Balance of supply and demand for garbage disposal services
4. Balancing the efficiency and fairness of garbage disposal methods
landfill
Landfill disposal requires a large amount of land. At the same time, harmful components in garbage can cause serious
pollution to the atmosphere, soil, and water sources, not only damaging the ecological environment but also seriously
endangering human health.
compost
Composting requires sorting and classification of garbage, with a high organic content requirement. Moreover,
composting cannot reduce waste and still requires a large amount of land.
incineration
The essence of incineration is to oxidize organic waste into inert gaseous substances and inorganic non combustible substances under high temperature and sufficient oxygen supply conditions, in order to form stable solid residues. Firstly, the garbage is placed in an incinerator for combustion, releasing heat energy, and then the waste heat is recovered for heating or power generation. After flue gas purification, a small amount of residual residue is discharged, buried or used for other purposes. Its advantages are rapid capacity reduction and thorough high-temperature harmless treatment, small footprint, minimal impact on the surrounding environment, and thermal energy recovery. Therefore, incineration treatment of MSW is an effective way to achieve harmless, reduced, and resourceful treatment. With the continuous enhancement of people's environmental awareness and the improvement of comprehensive utilization technologies such as heat recovery, the proportion of countries around the world using incineration technology to treat household waste is increasing year by year.
