Application of garbage disposal deodorant
Xi 'an Baqiao district landfill site
Xi 'an Baqiao Landfill is located in Xi 'an City, covering an area of more than 1000 mu and treating 10,000 tons of garbage every day, which is currently the largest landfill in China. The main odor is caused by the decomposition of organic components in garbage by bacteria, and 75-80% of domestic garbage is organic matter, including skin, leaves and stems, leftovers/vegetables, poultry, animal and fish skin, hair, viscera, fat, feces, scraps/blood water, leaves, waste paper, flowers and plants and animal bodies, and certain moisture. In the process of natural digestion, under the action of aerobic/anaerobic fermentation, odor is produced, especially in hot weather, due to the acceleration of fermentation, odor becomes more serious.
Project requirements are to completely and effectively reduce the odor concentration, deodorant can not harm the human body. The main odors are ammonia, hydrogen sulfide, organic amines, organic sulfur, volatile fatty acids and so on. In the field test of Bejing Division garbage deodorant, the plant extract is fully atomized through the atomizing spray device, and the radius of the droplets is 50-150um in space, which can effectively adsorb odor molecules in the air. After field testing, the product was very satisfied, and signed an annual supply contract with the project of plant deodorant, which effectively solved the garbage odor and improved the surrounding environment of the project.
Liling City Yingfeng Zhonglian environmental industry Co., LTD
Liling Yingfeng Zhonglian Environmental Industry Co., Ltd. is a subsidiary of Zoomlion Environment, mainly responsible for the harmless waste treatment and urban waste removal services in Liling city. The whole landfill area is more than 20,000 square meters, and the site sprays garbage special deodorant four times a day, respectively at 8:30, 10:30, 15:30, 18; 00. The landfill area is mainly dominated by odors such as hydrogen sulfide and ammonia. After the waste deodorant is diluted 200 times and sprayed, there is basically no obvious odor on the site. The removal rate of hydrogen sulfide and ammonia detected by the third party on-site sampling can reach 90%, and the removal rate of on-site odor concentration can reach more than 95%. The effect of on-site treatment meets the requirements of the group company.
Application of deodorant for sludge treatment
Baling Petrochemical Branch of Sinopec Group
Baling Petrochemical Group, one of China's top 500 enterprises, is located in Yueyang city, Hunan province. After more than 40 years of construction, Baling Petrochemical has become a leading petroleum refining, oil, chemical, fiber, fertilizer in one of the large petrochemical complex and the largest domestic SBS, epoxy resin, caprolactam and commercial cyclohexanone production base.
This project is for sludge deodorization in solid waste treatment. After our company's technical site survey and analysis, it is concluded that the odor of the site mainly comes from the odor produced in the sludge transfer and the odor produced by the sludge turned back and forth during the site excavator operation. The flow of the wind direction leads to the odor volatilizing freely in the factory. It is recommended to use a large high-pressure fog gun device, use the special odor eliminator of Bejing Shi Petrochemical, and use interval spraying, so as to maximize the disposal of the odor. After the vehicle transport sludge to the plant, it can also be sprayed when unloading with petrochemical special odor eliminator. After field testing, the product is very satisfied, and signed a petrochemical sludge deodorant supply contract with the enterprise, effectively solving the problem of environmental odor.

Application of demulsifier for waste liquid regeneration
Shaoxing Weli kitchen waste recycling Co., LTD
Shaoxing Weli Kitchen Waste Recycling Co., Ltd. is a subsidiary of Weli Environmental Protection, mainly responsible for kitchen waste recycling and kitchen waste liquid treatment in Shaoxing City, Zhejiang Province. The project produces 500 tons of waste liquid after centrifugal separation in one day, and the on-site process is anaerobic → aerobic → centrifuge → air flotation machine → effluent. After the wastewater treatment does not contain oil, it is pulled as a carbon source, and demulsifier is added to the end of the air flotation machine. However, multiple demulsifiers used before the site cannot be used. Highly recognized by the Wiley Group.
Application of decolorizing agent in electronic industry
Bide Heat Transfer Technology (Dongguan) Co., LTD
Beided Heat Transfer Technology (Dongguan) Co., Ltd. is a US-funded enterprise, belonging to the United States Highhigh Group, founded in April 2004, has developed into a considerable scale of domestic heat transfer processing enterprises. In the scale of the entire sewage operation system, the traditional flocculant cannot effectively remove the chroma in the wastewater. After more than a year of operation using our decolorizer series products, the on-site operation cost has been controlled, and the wastewater can be discharged stably to the standard. Since our decolorizer has the effect of removing total phosphorus, the front-end treatment also eliminates the use and addition of phosphorus removal agent. It has saved a lot of processing costs for enterprises and has been highly recognized by the US group headquarters.
