Reverse osmosis advanced treatment of leachate at the Shantou Leidashi Municipal Solid Waste Sanitary Landfill
2015-01-30
According to a report on the Shantou Daily website dated January 29, 2015, the Leidashi Municipal Solid Waste Sanitary Landfill is the only facility in the central urban area for the harmless treatment of household waste, handling approximately 1,350 tons of daily municipal solid waste generated by the city’s more than one million residents. Having operated at full capacity for over a decade, the landfill will undergo an expansion project on the “Xiangshanwo” hillside to the southeast, ensuring that the daily waste produced in the central urban area can be promptly treated in a manner that meets environmental standards. According to the Municipal Urban Management Bureau, land acquisition for the expansion has been completed, with construction expected to begin in May this year.
According to available information, the project has a total estimated investment of RMB 168.6 million. It is planned and designed with a short-term processing capacity of 1,500 tons per day and a long-term capacity of 410 tons per day. The expansion project is organized into “two zones and one system,” comprising a municipal solid waste landfill zone, a stabilized ash‑and‑slag landfill zone, and a leachate collection and treatment system. The main construction components include earthworks, groundwater and leachate diversion and drainage works, impermeable liner installation, stormwater diversion ditches, embankment structures, landfill gas collection and venting systems, and leachate collection and treatment facilities.
It is understood that, to prevent leachate from the landfill in the reservoir area from contaminating the local soil and groundwater, the project developer has designed the expansion’s impermeable barrier system to stringent standards and with a high initial benchmark, employing composite imported geomembranes to achieve complete isolation between the landfill and the underlying aquifer, thereby effectively mitigating leachate pollution. In addition, an advanced leachate treatment system has been implemented, utilizing advanced reverse osmosis technology to treat the leachate; the treated effluent fully complies with national discharge standards. Meanwhile, landfill gas recovery and purification technologies have been adopted: the waste is covered with soil and geomembrane, and the generated landfill gas is extracted, purified, and converted into commercial biogas, turning waste into a valuable resource.
