Before the end of 2014, Shaoxing City, Zhejiang Shengxin first sewage treatment plant a standard A standard transformation completed, December 31 to achieve water. It is the first large-scale wastewater treatment using activated carbon technology in China. It was listed as the first typical case of "Environmental Technology Solution for the Era of Effustry" at the 2015 (Ninth) Environmental Technology Industry Forum. Shaoxing Shengxin Sewage Treatment Plant clever use of activated carbon "The water coming out of the sewage treatment plant is like a stream of water." In the past two years, as long as anyone who has ever been to Shaoxing City, Zhejiang Province, Shengxin's first sewage treatment plant, has all shone forth. After the introduction of deep treatment process, Shengxin first sewage treatment plant effluent standards from a B up to a level A, and close to surface water class â…£ water standards. In 2015 (Ninth) Environmental Technology Industry Forum, Shengxin first sewage treatment plant standardization transformation project was listed as "environmental technology solutions for the effects of era" the first typical case, introduced to the industry. Standardization transformation, multi-party inspection by the recipe Shengzhou, Zhejiang Shaoxing, is the world's largest hometown of ties and silk knit apparel an important production base, only the annual output of tie clothing amounted to 16.424 billion yuan. Shengxin first sewage treatment plant to deal with 150,000 tons of wastewater a day, Shengzhou Industrial Park, 23 printing and dyeing enterprises, 11 paper-making enterprises and 14 other industrial wastewater must be disposed of here. According to Zhejiang Province, Shaoxing City, two levels of government requirements, by the end of 2014, Shengxin Sewage Treatment Plant a project A standard a standard transformation must be completed. Before and after, a total of dozens of sewage treatment companies and research institutes to Shengxin first sewage treatment plant to try. In order to do its utmost to ensure the reliability and operability of the process, Shaoxing Water Department has also repeatedly visited study tours. After many investigation and comparison, expert demonstration, Shengxin Sewage Treatment Plant a standard tender transformation of bold use of powdered activated carbon technology, the project is still 150,000 tons / day. BOT upgrade project using standard methods, by the water treatment plant in Hubei Jun-full investment in building. Lasted 6 months, December 31, 2014, after the standardization of the transformation of the sewage treatment plant to achieve water. Since the water has passed, the lifting process works well, and the effluent effect meets the engineering design requirements. The effluent COD is less than 50mg / L, the chromaticity is reduced from 30 times or even higher to 15 times, and the other major indexes also reach the first-level A discharge standard. A water quality what? According to technical staff, from the indicators, COD decreased by 16.7%, the main suspended solids dropped by more than half, ammonia nitrogen, total phosphorus decreased by more than 30%. Thousands of experiments, out of the clear water 30 minutes It is understood that Shengxin sewage treatment plant a standard transformation project in China for the first time using activated carbon process on a large scale deep treatment of sewage. "Many industrial enterprises, like plastics and petroleum industries, have a lot of chemical ingredients in them, and biochemical methods are not enough to purify them. Later they thought of activated carbon," said Xu Rong, an engineer at Hubei Junji Water Treatment Co., Ltd. It is understood that the powder activated carbon wastewater treatment is not a new technology, but to large-scale application, we must first reduce the suspended solids in sewage, but also to solve the problem of small amount of water. In order to grasp the adsorption efficiency of powdered activated carbon, water flow rate, the optimal design of carbon layer height, Hubei Junji Water Treatment Co., Ltd. After 11796 times the filter, finally obtained the ideal data. This experiment is still ongoing, in order to get the best data. With the ideal powdered activated carbon filtration data, the company designed a new, continuous, powdered activated carbon filter tank to accommodate powdered activated carbon, based on a well-established filter tank that can work long hours without interruption, with a 24-hour filter tank 10,000 tons of sewage. Hubei Junji Water Treatment Co., Ltd. Chief Engineer Liu Lujian introduced before the sewage through the activated carbon filter, first put some substances in the sewage filter aid, through the frame, remove the suspended solids in sewage, that is, sludge. In Shengxin WWTP, 10,000 tons of sewage produce about 3 tons of sludge, which is only 1/10 of other wastewater treatment processes. "From the inflow of sewage, plus filter aid, a filter, plus powdered activated carbon, secondary filtration, the whole process less than 30 minutes, the water out of the clear and transparent, some of the indicators meet or exceed the surface water table â…¢ class." Liu Lu Jian said . Reduce costs, less than two yuan per ton processing fee Powder activated carbon sewage treatment technology with efficient, thorough and so on. However, powdered activated carbon is expensive, high-quality coconut shell charcoal nearly ten thousand tons, second-hand powder activated carbon also five or six thousand yuan a ton "At present, the annual output of activated carbon in our country is only 600,000 tons per year. Our factory (Shengzhou Junji) needs 10,000 tons of activated carbon a year, and a sewage treatment plant used to 1/60 of the country's activated carbon is unrealistic, so it must be reused." Xu Ficus said. In order to use the activated carbon powder regeneration, re-use or even repeated use, Junji expert team searched the literature at home and abroad, from the laboratory to large-scale production and use, before and after spending tens of millions. In 2008, after six iterations of equipment, the company finally found a way to regenerate powdered activated carbon. Wang Xiaoxiang, chairman of Shengzhou Junji Sewage Treatment Co., Ltd., said that in order to reduce the activation cost, the engineer designed a new integrated activated carbon regenerator, which reduced energy consumption by 40% and output doubled. "Our activation rate is 105%, and activated carbon adsorbs organic matter in the sewage into active carbon during the activation process." Wang Xiaoxiang said activated carbon activated carbon has a better adsorption effect than new carbon since the pore size of the carbon is completely turned on . < 1 2 > Atm Roll,Credit Card Paper Rolls,Atm Receipt Paper,Thermal Roll Printer Jiangmen Hengyuan Label Technology Co., Ltd , https://www.hylabelprinted.com
