Background technique

With the rapid development of my country's social economy, the acceleration of urbanization, and the rapid improvement of people's living standards, the garbage and waste generated in the process of urban production and life have also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people. Health effects are also becoming more apparent. The massive increase of municipal solid waste has made it more and more difficult to dispose of waste, and the resulting environmental pollution and other issues have gradually aroused widespread concern from all walks of life. The country attaches great importance to environmental protection issues, and has made great progress in the prevention and control of domestic waste and sewage. However, while the output of urban waste in my country continues to increase, the development of classification, recycling and treatment capabilities and levels of domestic waste is relatively lagging behind. Garbage treatment technology is very weak, so the applicability of domestic waste treatment technology has become a very important problem in solving domestic waste. The treatment of domestic waste technology selection often becomes a difficult problem in municipal solid waste disposal.

In order to realize the industrialization, recycling, reduction and harmlessness of municipal solid waste in our country, we must face the problems of mixed collection, low content and calorific value of recyclable substances, and high moisture content and biodegradable organic content of garbage. Household garbage. A variety of technologies have been developed to address these issues, including recycling, landfilling, incineration, and composting.

However, the most critical problem is that in order to deal with the increasing discharge of domestic waste, a rapid waste treatment process and later resource recovery are required to meet this demand.
