Embodiment 1

[0046] combine figure 1 and figure 2 , a rain and sewage diversion and diversion system for a valley-type garbage landfill, which includes a partition dam 14, a sewage pipe, a rainwater collection pipe 13, a geotechnical composite drainage network 2 and a non-woven geotextile 5, wherein the landfill area 4 From bottom to top, there are 2.0mm thick HDPE double-rough film I1, geotechnical composite drainage network 2 with high-density polyethylene as the main raw material, gravel layer 3, landfill layer 41 and 600g / m 2 The non-woven geotextile 5, wherein, the geotechnical composite drainage net 2 extends from the bottom of the landfill area 4 wrapped with the crushed stone layer 3 to the bottom of the slope foot 6 of the landfill area, and the outer side of the geotechnical composite drainage net 2 is provided with a layer of double Rough film 1.0mm thick HDPEII11, double rough film II11 extends from double rough film I1 at the bottom of landfill area 4 to the bottom of slope ...

Embodiment 2

[0068] Such as figure 1 As shown, a partition dam 14 is set up at the downstream of the slope foot of the landfill area 4, the inner diameter of the sewage collection flower pipe 10 is 150mm, and the material is HDPE, and the sewage collection flower pipe 10 in the landfill area 4 is laid in parallel with the partition dam 14, Cut the high-density polyethylene geotechnical composite drainage network 2 laid on the base of the landfill area 4, cut along the direction of the landfill operation area, and weld the new high-density polyethylene geotechnical composite drainage network 2 at the cut, Form a whole to ensure that the entire downstream of the landfill area can be fully covered by the geotechnical composite drainage network 2 . The 2.5mm thick HDPE double-rough mask I(1) and the 1.5mm thick HDPE double-rough mask II11 directly below the incision are welded to each other, and laid to 6 places at the slope foot of the landfill area, and the sewage collection flower tube 10 i...

Embodiment 3

[0071] Such as image 3 As shown, the main function of the HDPE double-rough mask is to prevent leachate leakage, but the price is relatively expensive. In the case of satisfying the use function, the amount of HDPE double-rough mask can be reduced. In this embodiment, the 1.5mm thick HDPE mask is removed. The use of the double-rough mask means that the double-rough mask II11 is removed, only the geotechnical composite drainage net 2 is welded at the incision, and the thickness of the geotechnical composite drainage net 2 is appropriately increased, and the other parts are the same as in embodiment 2.

Abstract

The invention discloses a rain sewage diverting and guiding system of a valley-type waste landfill and a using method thereof and belongs to the field of waste landfills. The system comprises a partition dam, a sewage pipe, a rainwater collecting pipe, a geotextile composite drainage network and non-woven geotextile, wherein the position from the slope surface of a landfill region to the surface layer of a slope toe of the landfill region is provided with the layer of non-woven geotextile, the position from the lower face of the portion, on the slope toe of the landfill region, of the non-woven geotextile to the bottom of the landfill region is provided with a layer of double-coarse-face membrane II, a sewage collecting floral pipe is arranged in the landfill region, the sewage collecting pipe comprises the sewage collecting floral pipe and a sewage guiding and draining pipe which are communicated, and the sewage guiding and draining pipe is located in the partition dam which is further provided with the rainwater collecting pipe. The system aims at solving the problem that because rain sewage diversion of a valley-type waste landfill in the prior art is not thorough, the discharge amount of landfill leachate is increased, and the system has the advantages of being high in rain sewage diversion effect, easy to manage and low in constructing cost.

Description

technical field [0001] The invention relates to the field of waste landfill plants, and more specifically, to a rainwater and sewage diversion and diversion system for a valley-type waste landfill and a method for using the same. Background technique [0002] The valley-type garbage landfill is surrounded by mountains and valleys. It is built using natural gullies and valleys. It has the advantage of large storage capacity and has become the main form of domestic waste sanitary landfill. For a large-area valley-type landfill, if it rains, the rainwater from the garbage area will become sewage, which will mix with the rainwater from other areas, making the rainwater from the entire landfill become sewage. Undoubtedly increased the sewage treatment load. [0003] Chinese invention patent, authorized announcement number: CN101672069B, authorized announcement date: 2012.08.08, discloses a drainage method for a valley-shaped landfill, which is characterized in that the landfill ...
