Processing technology for harmlessly reducing city garbage and converting city garbage into resources

Abstract

The invention discloses a processing technology for harmless reducing city garbage and converting city garbage into resources. The processing technology comprises the following steps: step one, grabbing garbage; step two, sorting; step three, breaking the bags and grinding city garbage; step four, sieving the city garbage; step five, carrying out fermentation to degrade the garbage; step six, sieving the garbage; step seven, aging; step eight, sieving; and step nine, adding trace elements. The processing technology has the following advantages: (1) the environment pollution is eliminated, and the garbage is converted into resources; (2) the problem that the city is surrounded by garbage is solved, and the garbage is converted into resources and reduced harmlessly; (3) the cyclic utilization of resources is realized, the energy is saved, the discharge is reduced, the resources is maximally utilized, the environment is protected, the garbage is recovered and converted into resources, and no secondary pollution is generated.

Description

Technical field [0001] The invention relates to the field of garbage treatment, in particular to a process for reducing, harmless and resource utilization of urban garbage. Background technique [0002] Since the founding of the People’s Republic of my country, the method of dumping and burying abandoned potholes in suburban areas has been used in our country. The treatment method is extremely primitive, unscientific and unsanitary. Every winter and spring comes, the monsoon blows, and the ground garbage is scattered with the wind and spread to the urban area. Space has caused secondary pollution to the environment. In order to solve the problem of garbage disposal, the relevant departments of local and municipal governments have taken many measures, but they have not solved the problem fundamentally. Since the 1990s, the country has built a number of large-scale garbage treatment plants, but they still adopt backward burying treatment methods, and the secondary pollution cannot ...

AI Technical Summary

Problems solved by technology

Since the 1990s, the country has built a number of large-scale waste treatment plants, but still adopts outdated landfill treatment methods, and the secondary pollution cannot be solved fundamentally.

With the passage of time, a large amount of garbage has increased year by year, almost filling many potholes in the suburbs and nearby counties (cities), and districts. In places closer to the urban area, there is nowhere to dump the garbage, especially for some individuals with low awareness of environmental protection. Poor units and individuals, regardless of the overall environment, take the opportunity to dump at will, which further affects the public environmental sanitation in the urban area and aggravates the pollution level in the urban area
