How to deal with rural domestic waste? With the development of social economy, people's living standards are constantly improving, and urban and rural domestic waste is increasing year by year.

The daily amount of garbage per capita in cities is 1-1.2kg/d, and the daily amount of garbage per capita in rural areas is 0.8-1kg/d, which is a big change from the reference value of 0.6-0.8kg/d in normal years. Garbage is thrown everywhere, piled up on both sides of the road, the river is blocked, and the pungent odor affects the appearance and causes damage to the ecological environment. However, the countryside is the supply place for urban food, and the protection of the ecological environment in rural areas is directly related to the safety of urban food.

The current situation of rural domestic waste

Waste plastics account for more than one-third of domestic waste and have been difficult to dissolve for hundreds of years. If burned, it will produce various polluted air. If buried in the soil, it will affect the growth of plant roots, change the soil structure, and even pollute groundwater.

According to media reports, except for county towns, two-thirds of China's 668 cities are surrounded by garbage, and one-quarter of cities have no landfills. The total land occupied by urban garbage dumps in China exceeds 500 million square meters, and the annual economic loss reaches 30 billion yuan.

At present, the annual increase in domestic garbage and the difficulty in effective treatment have brought great pressure to the sustainable development of the social environment.

How to deal with rural domestic garbage harmlessly

1. Treatment methods for garbage dumping and stacking

Simply transfer pollutants. Concentrated garbage disposal in the open air is very harmful to the environment. Harmless garbage disposal refers to the use of physical, chemical, biological and thermal treatment methods to treat garbage so as not to pollute the surrounding environment and harm human health.

2. Garbage incineration treatment

Incineration of garbage will produce harmful gases, organic matter and slag. Direct discharge of these into the environment will also cause pollution. Therefore, it is necessary to put garbage in the incinerator for centralized treatment. A part of domestic garbage does not contain organic matter, and can be mixed with coal and garbage in a certain proportion for incineration.

3. Garbage incineration power generation technology

After incineration in the incinerator, the heat generated can be used to generate electricity. Garbage incineration power generation technology can not only solve the environmental pollution caused by open-air incineration of garbage, but also effectively utilize the energy in garbage, killing two birds with one stone.

4. Sanitary landfill of garbage

With the continuous development and improvement of garbage disposal technology, the load of urban garbage from garbage disposal to garbage landfill is too large, and garbage landfill technology also tends to be sanitary, economical and efficient. Waste materials such as ash, bricks, ceramics, and various residues produced after domestic garbage disposal projects are landfilled.
