Problems solved by technology
[0010] The invention provides a gas injection system and method for aerobic treatment of garbage landfills. By periodically switching the gas injection channel and the gas extraction channel, the gas flow is easy to form a specific channel inside the garbage dump, causing uneven gas diffusion and waste disposal. Incomplete aerobic reaction of the heap

The invention provides a system and a method for pumping and injecting gas for aerobic treatment of a refuse landfill. The system comprises a gas injection device and a gas pumping device which are arranged on the ground, and further comprises a gas injection well and a gas pumping well which are buried in a refuse dump body. The system is characterized in that the gas injection device communicates with one of the gas injection well and the gas pumping well in a switching manner through a switching device; and the gas pumping device communicates with the other one of the gas injection well andthe gas pumping well in a switching manner through the other switching device. According to the system and the method, by controlling switching between a forward mode and a reverse mode, a specific channel can be prevented from being formed in the refuse dump body by gas flow, and uniform distribution of the gas is ensured.
Description
technical field [0001] The invention relates to the field of stock landfill treatment, in particular to an aerobic treatment gas injection system and method using aerobic stabilization treatment technology. Background technique [0002] At present, due to the relatively short time for the sanitary landfill treatment of garbage in my country, economically developed cities only generally adopted it in the middle and late 1990s, and the longest time was less than 20 years, while some economically underdeveloped areas, Many cities now also use informal landfill techniques for landfilling. As a result, there are a large number of informal landfills that are already filled with waste. These landfills not only occupy a large amount of land resources, cause serious pollution to water bodies and the atmosphere, but also have adverse effects on the image and development of the city. With the rapid development of urban construction, some informal landfills are located in the urban are...
