The harmless treatment of domestic waste is a very important part. Do you know the main methods of harmless treatment of domestic waste? Welcome everyone to discuss and exchange with Holy Shield.

As we all know, the main methods of harmless treatment of domestic waste include sanitary landfill, incineration, and composting.

[Sanitary Landfill]
With the continuous development and improvement of waste treatment technology, urban waste is transitioning from stacking to landfill. Landfill technology is gradually becoming hygienic, economical and efficient. The ash, bricks, ceramics and other substances contained in the garbage and various residues generated after the garbage disposal must be disposed of by landfill.
[Incineration]
The garbage is sent to the incinerator for centralized treatment, and the incineration of garbage in the incinerator adopts a thermochemical treatment method. This method uses high temperature to destroy and change the composition and structure of the garbage, reducing the volume of the garbage and making it harmless. After incineration, the volume can generally be reduced by 80%-90%, and the harmful substances and germs are basically removed. On the basis of incineration in the incinerator, the generated heat can be used to generate electricity. Such as the domestic waste incinerator made by Holy Shield.

[compost]
In recent years, garbage disposal and composting has developed rapidly. Since the 1980s, the "secondary fermentation process" has been applied. Due to the forced sealing, the fermentation cycle has been shortened, the composting machinery has also been improved, and the production has become industrialized. From a national perspective, a mechanized waste composting production line suitable for China has been designed by itself, but many cities still have a considerable number of simple waste composting plants.

The best way to deal with household waste is to sort it. Sorting and classifying obsolete waste, crushing construction waste to make sand, crushing construction waste to make bricks; recycling iron blocks and glass slag; wood chips and plastic products are dried and shredded to generate biomass particles, which are used to replace coal for power generation, Substitute coal for burning, turning waste into treasure, and the utilization rate of resources is relatively thorough, which can basically achieve no landfill. This method is not only environmentally friendly, but also energy-saving, simple and easy to operate, safe and pollution-free during operation.
