With the development of township economy and the continuous growth of population, the problem of domestic waste disposal is becoming increasingly prominent. Among them, waste incineration has become an effective treatment method. However, the incineration process produces large amounts of fly ash, which can be harmful to the environment and human health if not properly disposed of. Therefore, how to properly dispose of these fly ashes has become an urgent problem to be solved.
At present, the common township domestic waste incineration fly ash treatment methods mainly include the following: 1Landfill method: Fly ash is transported to a designated landfill for landfill. This method is simple and easy to implement, but it needs to occupy a lot of land resources and may cause secondary pollution. 2.Curing treatment: By adding a curing agent, the fly ash is converted into a hard solid block, which can then be landfilled or recycled. Curing treatment can reduce the harmful substances in fly ash and reduce the harm to the environment. 3.Chemical treatment: through chemical methods such as acid-base neutralization and redox, the harmful substances in fly ash are removed. The chemical treatment effect is good, but the treatment cost is high. 4.Resource utilization: the use of useful substances in fly ash, such as extracting metals from fly ash, making building materials, etc. Resource utilization can not only reduce the amount of garbage disposed of, but also create economic benefits. 
In practical application, the appropriate treatment method can be selected according to the actual situation. At the same time, it is also very necessary to strengthen environmental protection publicity and education, improve residents' awareness of environmental protection, and reduce the generation of garbage from the source. Only in this way can we achieve the goal of waste reduction and resource utilization, and promote sustainable economic and social development.
