Dongguan dump leachate treatment technology can change “Coke” to “Sprite”

Disposal of rancid odor rubbish can be classified into four categories: combustibles, non-combustibles, scrap metal and soil within just ten minutes after being processed by “separation technology”. Soil and non-combustible materials are used for construction purposes after being detoxified, and combustible materials such as plastics are processed into waste-derived fuel for reuse, thereby achieving the effect of “turning waste into treasure”. The black landfill leachate is poured into the container like "Coke". After passing through the MNBS landfill leachate treatment technology, it can become crisp and transparent harmless liquid, such as "Sprite" as clean and bright. This is the scene that the reporter saw on July 25 at the Xiaojinkeng waste emergency landfill site in Changping Town, Guangdong Province. On the same day, the Xiaojinkeng Garbage Emergency Landfill Leachate Treatment System was officially launched and can handle 2,000 cubic meters of garbage every day. It is expected that the Xiaojinkeng Garbage Emergency Landfill will be able to dispose of more than 10 years of inventory in 2 years. clean. After the inventory of waste is disposed of, the emergency landfill will be ecologically restored and will effectively promote the pollution remediation of the Shima River. The Municipal Urban Management Bureau stated that this is the first landfill leachate treatment pilot project in Dongguan, which is funded by environmental technology companies. After the treatment results have been checked and accepted by the Shanghai Urban Management Bureau and the Municipal Environmental Protection Bureau, the results will be considered if the actual results are good. Promote it throughout the city. "Separation technology" can process 2000 cubic meters of garbage per day On July 25, in the roar of the machine, Guo Shubo, an engineer at Hengyi Environmental Technology Company, told reporters that “through the 'separation screen' technology, any pile of stored garbage can be sorted as combustible, non-combustible, and waste. There are four major types of materials, such as metal and soil.” This set uses advanced Korean patented technology, uses wind and high-efficiency silent drum screens to sort the stock garbage, and divides the screening materials for recycling and harmless treatment. At present, the project All equipment installations have been completed. The operation stage is now officially underway. “After processing 2,000 cubic meters of rubbish per day, it is estimated that within a two year period, the 1 million cubic meters of rubbish can be disposed of in the Xiaojinkeng Garbage Emergency Landfill. ." According to the introduction of the Municipal Urban Management Bureau, the Xiaojinkeng Waste Landfill is an old quarry left over from the early days. It is surrounded by mountains on three sides and covers an area of ​​30 acres. The land is used for simple landfilling of domestic waste. Since 2011, the government of Changping Town has been used as an emergency landfill site for domestic garbage. At present, the landfill site contains about 1 million cubic meters of waste, and it is still processing more than 300 tons of new life each day, and the waste pile is over 50 meters. Guo Shubo told reporters that after “screening”, the soil and non-combustible materials generated from the stored garbage can be used for construction purposes after being harmlessly treated, and combustibles such as plastics can be processed into waste-derived fuel for reuse. This “separation technology” mainly has three major advantages. It adopts a comprehensive treatment process, which can handle new and old wastes at the same time. It can effectively treat the existing waste while meeting the daily necessities of the newly added waste, and can comprehensively dispose of the waste through the waste separation technology. The majority of construction waste, humus, and metals were selected and comprehensively used, in line with the concept of circular economy; high processing efficiency, a single production line designed to handle a scale of 2560 tons/day, and a reduction of 70% in the volume of stock after treatment the above. "In two years, we can clean up the 1 million cubic meters of waste in Xiaojinkeng." Guo Shubo is full of confidence. Leachate treatment technology can change "Coke" to "Sprite" "A cup of caffeine is like a dark, a cup is like a sprite, and Bai Jie is transparent." At the entrance of the Liaojinkeng Domestic Garbage Emergency Landfill, a new leachate collection tank was built with 600 cubic meters. The staff explained to the reporter that “black cola liquid is penetrated by stock rubbish. Transparent liquid is treated by MNBS landfill leachate treatment to turn black liquid into white.” The main facilities for landfill leachate treatment include conditioning tanks, ammonia nitrogen molecular sieve separators, nano-bioreactors, multi-stage adsorption separators and other processing facilities. The landfill leachate passes through the pipeline laid at the bottom of the landfill and is introduced into the treatment facilities in a centralized manner. Through ammonia nitrogen molecular sieve separation, high-efficiency nano-biodegradation, and multi-stage countercurrent adsorption, the three processes can effectively remove pollutants such as suspended solids, heavy metals, and ammonia nitrogen in the leachate. After purification. Thanks to the integration of ammonia nitrogen molecular sieve technology, nano-membrane bioreactor technology and high-efficiency adsorption technology, the landfill leachate can be completely detoxified without the problem that the concentrated solution produced by conventional reverse osmosis technology cannot be processed.
