Domestic waste landfill zoning platform landfill zoning coverage HDPE Geomembrane ，Zoning garbage cover according to relevant landfill specifications HDPE Overlay film. Due to the complex covering environment, the covering area reaches tens of thousands of square meters, and the joints of the covering films are long, it is inevitable that some covering films will have leaks. Landfill staff use their free time to repair the leaks of the covering films. “The film was laid for 2 and a half hours in the morning, and a total of 5 sheets were laid.” Covering film “refers to the high-density polyethylene geomembrane covered on the garbage.” After the garbage is landfilled, covering it with this film is equivalent to putting a’coat’on the garbage, which can reduce the odor. “
Laying process of garbage dump covering film
Sub-unit landfill, garbage paving and compaction are not relaxed. The landfill reservoir area is equipped with two zoned earth embankments to divide the entire reservoir area into three landfill areas. A sub-unit landfill plan for the whole year is formulated and the operation unit is controlled according to the requirements of the specification, the leachate drainage pipes at the zoned earth embankments are cut off and blocked, the rainwater and sewage diversion is implemented to the maximum extent, the amount of leachate produced is reduced, and environmental risks and production costs are effectively reduced.
Landfill uses special machinery, bulldozers and compactors for paving and compaction. The compaction density of garbage is regularly tested, the composition of garbage is regularly analyzed, and layered rolling and layered paving are carried out as required. The single-layer paving thickness is controlled at 0.5 to 1 meter, and the unit thickness is controlled at 4 to 6 meters.
3、Cover it every day to prevent the spread of odor, and at the same time reduce rainwater from entering the garbage dump, control the breeding of mosquitoes and flies, and prevent the spread of odor.
The area under coverage in the waste treatment plant site will be operated every afternoon 1.0 HDPE The membrane is temporarily covered, and all areas outside the working face are 1.0 mm It is covered with high-density polyethylene film, and the covering film in the area that has not been operated for more than 15 days is jointed and welded. The clear water on the film is discharged through the natural slope or the rainwater drainage ditch set in the site, so as to reduce rainwater from entering the garbage dump, and effectively control the breeding of mosquitoes and flies and the spread of odor. This link is very important, especially for the diversion of rainwater and sewage. In winter, we will complete the dredging and maintenance of flood interception ditches, temporary road reinforcement in landfill areas, inspection and repair of covering films, construction of zoned earth embankments, and relocation and erection of pumps in advance. Make full preparations for strengthening production safety and reducing environmental risks during the rainy season. ”
The contact part between the garbage dump and the slope in the reservoir area is set at 50 CM Sand bag protective layer, the slope is controlled below 1: 3, and the heap elevation control is divided into longitudinal slope and transverse slope mode. The filled area is adopted HDPE Membranes undergo mid-term coverage.
4、There is no omission in the disinfection of the site. Sprinklers are used to directly add chemicals to the roads in the site, and wind cannons are used to carry out automatic spraying operations for disinfection and deodorization. At the same time, the coverage of operation units is strengthened. At present, the control effect of mosquitoes, flies and odors in the site is good.
Anti-flying nets are installed at both ends of the landfill site to effectively block flying objects.
