Embodiment Construction

[0048] Examples see figure 1 As shown, this valley-type garbage landfill is connected in series with multi-section rain and sewage diversion devices, including the landfill area separated by the partition dam 3, and the HDPE anti-seepage film is laid on the surface of the partition dam 3, and it is connected with the HDPE anti-seepage membrane laid on the landfill area. The seepage membrane is welded into a whole, and there is a garbage dam 10 downstream of the landfill area, and a leachate sewage regulating pool 6 and a valve well 7 are arranged outside the garbage dam. There are thirteen separate landfill areas from upstream to downstream, each landfill The area is connected in series by the same blind ditch 1 for leachate drainage. There are perforated HDPE seepage guide pipes 2 in the leachate guide drain blind ditch. A pre-embedded casing 18 is set across the partition dam 3, and a valve I4 is installed on the HDPE seepage guide pipe 2 downstream of each partition dam 3,...

Abstract

The invention discloses a valley-type refuse landfill series multi-partition rain and sewage shunting device and a valley-type refuse landfill series multi-partition rain and sewage shunting method. The device comprises landfill areas spaced by area partition dams, more than four landfill areas are partitioned from upstream to downstream, the landfill areas are connected in series by the same percolate guide and drainage blind ditch, a high-density polyethylene (HDPE) percolate guide duct with perforations is arranged in the percolate guide and drainage blind ditch, the refuse landfills of the landfill areas are sequentially from upstream to downstream, a percolate collecting pit is arranged at the sewage gathering bottom of the landfill area which is being filled, and a sewage submersible pump is arranged in the percolate collecting pit; and the percolate is delivered to a percolate sewage adjusting tank through the sewage submersible pump and a hose. By adopting the device and the method, the problem of rain and sewage shunting of a newly built valley-type landfill can be well solved; and the generating quantity of the sewage of the landfill is greatly reduced, so that the scale of percolate treatment equipment and facilities is reduced, a large amount of percolate and sewage treatment cost is reduced, and energy saving and emission reduction are realized.

Description

[0001] technical field [0002] The invention relates to a rain and sewage diversion device and method suitable for valley-type garbage landfills. Background technique [0003] Sanitary landfill is a solid waste treatment technology widely used at home and abroad. Landfill leachate is the main pollutant produced by sanitary landfill. The concentration of organic matter in leachate is high, the treatment is difficult, and the treatment cost is high. The treatment of landfill leachate is one of the key issues in the construction and operation of landfills. [0004] Sanitary waste landfills are divided into plain landfills, beach-type landfills and valley-type landfills according to different landfill sites. [0005] Compared with valley-type landfills, plain landfills are easier to realize division because of their advantages of easy shaping when the site is leveled, so that rain and sewage diversion is easier to realize. [0006] Tidal flat landfills are mainly located on ...
