Problems solved by technology

[0006] Compared with the three technologies, the transportation cost of the off-site sanitary landfill is high, and it will cause a load impact on the planned sanitary landfill, which reduces the landfill life; There will be dangers in the process, and direct landfill after screening will cause secondary pollution in the later stage
[0007] The in-situ treatment technology of garbage dumps that has been used in China is to carry out surface greening after the site is closed, but the pollution generated by the garbage dump is still discharged and treated in the same way after

Embodiment Construction

[0026] Please refer to the attached figure 1 to attach Figure 4 Shown, the present invention is a kind of method that is used for the in-situ biological treatment of domestic refuse landfill, and it comprises following processing steps:

[0027] 1), field shaping 1

[0028] It is necessary to determine a boundary 5 for the field area, and perform steps such as compaction of the garbage within the boundary 5, shaping of the top 6, and shaping of the side slope 7. Wherein, the compacted density is 450~880kg / m 3 ; The slope of the top is 3-5%; The slope of the slope is 1: (3-5); This is not only beneficial to rainwater discharge and collection, but also meets the requirements of subsequent utilization, and does not generate secondary handling costs . And the buffer zone, such as the horse track, etc., needs to be determined according to the requirements of slope and pile height. The final shape of the site needs to be determined based on factors such as garbage composition,...

Abstract

The invention relates to an in-situ biological treating method for a municipal solid waste landfill, which comprises the following steps: 1) reshaping a field area; 2) preventing the field area from leaking; 3) covering the field area; and 4) performing aerobic in-situ biological treatment on the field area. According to the in-situ biological treating method for the municipal solid waste landfill provided by the invention, the waste landfill can be treated within a controllable area; the parameters required by treatment can be precisely calculated; the whole treating process is accurately monitored; the whole process is under a completely closed state; and the secondary pollution to the external environment during the treating process is avoided.

Description

【Technical field】 [0001] The invention relates to a treatment method of domestic garbage, in particular to a method for in-situ biological treatment of domestic garbage landfills, and belongs to the technical field of environmental pollution control. 【Background technique】 [0002] According to the "Twelfth Five-Year Plan" National Urban Household Waste Harmless Treatment Facilities Construction Plan, by the end of 2010, the annual domestic waste removal volume in facilities cities and counties across the country was 221 million tons, and the harmless disposal rate of domestic waste was 63.5%. Among them, only 27.4% are counties. Moreover, there are still many planned goals during the "Eleventh Five-Year Plan" period that have not been completed, and the capacity for harmless disposal of garbage is far behind the amount of garbage generated. [0003] At present, China's waste treatment technology mainly adopts landfill, composting, incineration and other methods. Landfill ...
