China has a large population, and the degree of urban centralization is getting higher and higher. It is not only a question of education, morality and mechanism, but also depends on the improvement of national living habits and the rationalization of garbage classification. Touching the shocking environmental pollution and the sources of all kinds of garbage, the environmental problem has been very serious, and the pollution and degeneration of garbage to life has become the top priority of environmental governance.
Many different kinds of garbage are produced in cities. For example, the garbage produced by various communities can be classified as general domestic garbage, while the garbage produced by hospitals and health departments can be classified as medical garbage. The garbage dumped in restaurants, restaurants and school canteens every day is also called kitchen waste. The garbage recovered by various mechanical processing plants and waste recycling stations needs to be thoroughly classified because of its wide variety.
Specifically, the garbage in urban life can include ordinary domestic garbage, kitchen garbage, medical garbage, chemical garbage, construction garbage, industrial garbage, plastic garbage, wooden garbage, and various small animal carcasses.
With the aggravation of the environmental deterioration trend, the state's investment and efforts in environmental protection are deepening, and environmental protection equipment, especially various harmless treatment equipment, has become the key area for the future development of the machinery industry.
For all kinds of domestic garbage, kitchen garbage and animal carcass garbage, the previous treatment methods were generally incineration and landfill. This method has great disadvantages and can easily cause soil pollution and secondary pollution.
At present, with the continuous growth of national economy and the gradual improvement of urbanization level, the per capita consumption level of urban residents has reached an unprecedented height, and the environmental pollution problems encountered are becoming increasingly serious. With the increasing awareness of the country, people and the environment, various garbage and pollution treatment technologies have become the focus of current social and industrial development.
At present, the recycling technology of urban residents' domestic waste is close to maturity, and all kinds of domestic waste treatment equipment and biodegradable equipment have achieved good results, so it is only necessary to increase the promotion and utilization of society.
