Problems solved by technology

[0008] Aiming at the problems of low heterotopic aerobic stabilization degree, long stabilization period and poor technical controllability in the prior art, the present invention provides a system and method for heterotopic aerobic enhanced stabilization of domestic waste, through An aerobic enhanced stabilization system with parallel units, sequential batch operation, ventilation, humidity control, temperature control and other artificially enhanced technologies is built at the excavated material site, that is, an aerobic fixed bed bioreactor, which is aimed at the existing domestic waste excavated materials In the process of ex-situ stabilization, odorous gas pollution is controlled and the water content is effectively controlled to shorten the stabilization cycle, which can achieve the pretreatment goal of rapid stabilization of excavated waste within 1 week, and improve subsequent sorting and resource utilization Technology Efficiency Needs

Embodiment 1

[0062] In this embodiment, aiming at the heap with low water content, an ex-situ aerobic enhanced stabilization system for existing domestic waste is adopted, which includes the following units:

[0063] Such as figure 1 As shown, the parallel corridor unit 100 located on the excavation site is composed of multiple longitudinal partition walls 101 and transverse partition walls 102 perpendicular to the longitudinal partition walls 101; the transverse partition walls 102 and The longitudinal partition walls 101 respectively form unit corridors 103 with outlets 104 at both ends, and multiple longitudinal partition walls 101 and transverse partition walls 102 form several unit corridors 103, forming parallel corridor units 100;

[0064] Such as figure 2 and Figure 4 As shown, the drainage and air distribution unit 400 located on the floor of the unit corridor 103; the drainage and air distribution unit 400 used in this embodiment is the drainage and air distribution device di...

Embodiment 2

[0073] In this embodiment, for the piles with high water content, the difference between the ex-situ aerobic strengthening and stabilization system for the stock of domestic garbage adopted in Example 1 is that the drainage and air distribution unit is installed between the piles and the floor with a certain The gravel layer 407 of the slope, the gravel layer 407 is connected to the blower fan 406 arranged on the top of the longitudinal partition wall 101 and / or the transverse partition wall 102 through the air inlet pipe 405; The stored domestic waste is ventilated, and the air is fully air-intaked to achieve uniform air distribution.

[0074] This embodiment relates to a method for ex-situ aerobic strengthening and stabilization of excavated waste excavated by using the above-mentioned system, including the following steps:

[0075] combine figure 1 , The excavated waste with high moisture content in the informal landfill is transferred by dump truck to the ex-situ aerobic ...

Abstract

The invention discloses a household waste inventory heterotopic aerobiotic strengthening stabilization system and method, and belongs to the technical field of environment protection. The system comprise the following units that a parallel gallery unit, a drainage and air distribution unit, cover films and a capillary water distribution unit, wherein the parallel gallery unit is located on a dug object placement site and composed of N longitudinal partition walls and transverse partition walls perpendicular to the longitudinal partition walls, the transverse partition walls and the longitudinal partition walls form unit galleries of which the two ends are provided with outlets, and the N longitudinal partition walls and the transverse partition walls form 2(N-1) unit galleries to form theparallel gallery unit; the drainage and air distribution unit is arranged on the terrace of the unit galleries; the cover films are arranged at the tops of the unit galleries and can be folded or unfolded; and the capillary water distribution unit is arranged above the parallel gallery unit. By adopting the aerobiotic strengthening stabilization system, the stabilization cycle can be effectively shortened, the target that waste inventory dug objects are quickly and stably pre-processed within one week is achieved, and the follow-up sorting efficiency and the resource utilization technology efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and more specifically relates to a system and method for ex-situ aerobic strengthening and stabilizing of domestic garbage. Background technique [0002] Existing waste refers to old waste from informal landfills, non-standard landfills and regular landfills. Before 2000, there were basically no sanitary landfills in my country, and all urban and rural domestic waste was sent to informal landfills or quasi-sanitary landfills. In the past two decades, sanitary landfills have been fully covered in administrative areas above the county level. At present, there are about 8 billion tons of garbage in the country (about 27,000 informal landfills, covering an area of ​​500 million m 2 ; There are about 2,000 formal sanitary landfills), of which there are about 2 billion tons of plastics, 1.5 billion tons of fabrics, 500 million tons of masonry, and 4 billion tons of stale organic matte...
