Household garbage integrated treatment and resource utilization environmental protection system

Abstract

The invention discloses a household garbage integrated treatment and resource utilization environmental protection system which comprises a garbage bin, a uniform feeding device, a first-stage magnetic separator, a first-stage crusher, a second-stage magnetic separator, a primary treating pond, a second-stage crusher, a second-stage treating pond, a punching cutting machine, a third-stage magnetic separator, an acidification anaerobic tank, screening equipment, a buffer regulating tank, a deep anaerobic tank and a sludge settling tank which are sequentially arranged in an equipment room. According to the household garbage integrated treatment and resource utilization environmental protection system, no garbage sorting is needed, the garbage sorting and screening are performed in the whole process of garbage utilization, the great bottleneck of restraining the garbage treatment is overcome, and the practicability is relatively strong; the treatment cost is not increased, the huge economic benefit can be obtained; the serialization of treating garbage by using an anaerobic method can be achieved, the treatment amount is relatively large; the problem that non-anaerobic garbage such as waste plastics and waste chemical fibers in the garbage can not be recycled is thoroughly solved, so that resources in the garbage are completely recycled.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environmental protection system for comprehensive treatment and resource utilization of domestic garbage. Background technique [0002] Human beings have only one earth, the earth is the home we live on, and this home is being surrounded by garbage. Domestic garbage is a by-product of human life. With the rapid development of social economy and the high concentration of urban population, the output of domestic garbage is gradually increasing. The harm of garbage to human life and the environment is mainly manifested in the following aspects. [0003] First, it occupies too much land. Garbage piled up on the outskirts of the city encroached on a large amount of farmland. At present, each Beijinger produces an average of 440 kilograms of garbage per year, and the city's annual output is about 4 million tons, which is equivalent to two and a half Jingshan Mountains. The...

Problems solved by technology

[0004] Second, air pollution

[0005] Third, pollute the water body

[0007] Fifth, fire hazards

With the increase of organic matter content in urban waste and the change from open scattered storage to centralized storage, and only simple coverage in long-term storage, the harm of methane generated by garbage has become increasingly prominent, and garbage explosion accidents continue to occur, causing heavy losses

[0008] Sixth, the nest of harmful organisms
