Embodiment Construction

[0042] Below in conjunction with accompanying drawing and specific embodiment the specific embodiment of the present invention is described in further detail:

[0043] like figure 1 As shown, the embodiment discloses an aerobic ecological restoration system for obsolete domestic waste landfills, which mainly includes: gas injection subsystem, air pumping subsystem, leachate irrigation subsystem, leachate pumping and storage subsystem, Landfill gas combustion subsystem, monitoring subsystem.

[0044] Inject air, oxygen or a mixture thereof into the garbage dump body 1 through the air injection subsystem to ensure normal aerobic reaction in the garbage dump body 1 . In the design process of aerobic remediation process, the theoretical oxygen demand of the aerobic remediation process of the garbage dump is firstly calculated according to the characteristics, content, gas production rate and other basic data of the biodegradable organic components in the garbage. However, due to...

Abstract

The invention discloses a garbage landfill aerobiotic ecological restoration system. The system comprises the steps that an air injection subsystem injects air, oxygen or a mixture of the air and theoxygen into a garbage heap body; an air drawing subsystem draws landfill gas in the garbage heap body and feeds the landfill gas into a landfill gas combustion subsystem to be combusted; a leachate drawing regulation and storage subsystem collects and stores garbage leachate in the garbage heap body; a leachate irrigation subsystem draws the garbage leachate and injects the garbage leachate into the garbage heap body again; and a monitoring subsystem monitors the operation condition of the system. According to the system, the aerobic biology reaction treatment technology is taken as a body, the air or oxygen, the leachate and the like are added to a landfill through a controllable manner according to the biology degradation needs of garbage in the landfill, the landfill garbage biology degradation and stability rate is accelerated, leachate reinjection fully utilizes various microorganisms and water, degrading of organic matter in the garbage is accelerated, the treatment cost is reduced, meanwhile, the landfill torch combustion technology is utilized, the landfill gas is treated in a centralized manner, and emission of greenhouse gas is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste landfill management, and in particular relates to an aerobic ecological restoration system and method for a waste landfill. Background technique [0002] The amount of domestic waste generated in our country is huge, and with the continuous acceleration of the urbanization process in our country and the continuous improvement of people's living standards, the output of urban domestic waste has increased sharply. According to the statistics of the National Environmental Protection Agency, the annual output of urban waste in my country was 152 million tons in 2010, and it will reach 210 million tons by 2020, with an annual increase of 8% to 10%. The continuous growth of garbage has brought many problems to urban construction and other aspects. Domestic garbage seems insignificant, but if it is not managed and handled properly, it will undoubtedly have many negative effects, and it has become a bottlen...
