Membrane technology to achieve substantial progress in treatment of industrial wastewater – membrane
Article by hi joiney
(844, ‘In recent years membrane bioreactor MBR reverse osmosis membrane integration of technology in our urban sewage industrial waste water treatment has made great progress In the recently held meeting to promote wastewater treatment membrane technology China Environmental protection Wang Xinfang Industry Association said membrane technology for the effective emission reduction and the achievement of water resources has strategic importance of membrane technology in controlling water pollution the time has come br br Market has started specialized membrane technology companies with br Present the Chinese film consumer market accounts for 20 of global consumption It is understood that the actual membrane technology is the membrane separation technology compared with traditional separation technology high efficiency energy saving environment friendly easy to control the process convenient operation easy integration with other technical advantages Membrane technology is the best water purification and purification means water can be removed using the membrane suspended solids bacteria toxic metals and organics br br Department of Environmental Protection Science and Technology Xu deputy director the standard tree who told reporters that the reason of membrane technology in the past China did not disseminate and reasons first the lack of technology support in many areas of membrane technology we are still in the exploration stage second film material were mostly foreign production high prices the cost of membrane technology to wastewater treatment increased br br Recent years China 39 s number of membrane technology application and development of technology and professional company came into being China National Bluestar Group Environmental Engineering Shenzhen Jindal company Beijing clean water sources Xiamen Wei Shibang company Tianjin Motian Membrane Corporation after years of effort already has a team with our own R amp D capabilities of membrane technology and talents in membrane technology for waste water treatment works has also made outstanding achievements and some has become a set of membrane technology R amp D design construction installation operation and management in one of the specialized membrane technology companies This is our country made great progress in membrane technology an important symbol br br At the same time due to domestic film desalination rate of 99 7 to reach the world advanced level the price of foreign products less than 1 3 cost advantages result from the previous market structure competition between foreign companies started to change for the Chinese and foreign enterprises in competition br br According to the China Membrane Industry Association at present China 39 s film industry has more than 120 research units about 400 manufacturers engineering firms about 2000 basically all kinds of films can be produced At present China 39 s film consumer market has become one of the world 39 s three major sections accounting for 20 of global consumption With such a number of technology and specialized engineering company operating company our membrane technology in pollution control cleaner production and other applications will have a more promising future br br Effective simultaneous nitrogen and phosphorus removal wastewater treatment can be realized in situ in situ recycling br br In membrane technology promotion meeting the reporter learned that a number of membrane technology companies with MBR technology in municipal wastewater sewage treatment not only improves the results significantly reduce the chemical oxygen demand and ammonia emissions and wastewater treatment reuse can be achieved after the level of resources to achieve the life of the sewage br br Wang Xinfang said membrane technology in dealing with the application of urban sewage is a major technological advances to improve local water quality is important Currently domestic wastewater treatment using membrane technology both distributed processing units daily capacity from a few tons to several hundred tons or centralized treatment plant treatment capacity from a few thousand tons to several million tons are successful operation has been typical for the next promotion to create experience Clean water sources such as Beijing Huairou District in several residential areas domestic wastewater using MBR technology for processing greatly improve the local water quality br br Shenzhen Jindal company using MBR technology manufacturing integration of sewage treatment plant handles size from a few tons to several hundred tons after years of research and development has received a number of technology patents good effect the effluent can be achieved reuse level while the device is running a small amount of sludge nitrogen and phosphorus removal simultaneously effective br br 39 s Park in Nanchang Hong Dugong see Jindal company 39 s membrane technology park water processor in the depths of the iceberg automatic operation 24 hours a day In the green tank next to the bubbling stream to complement the clear water park next to the lake Liao Zhimin chairman said here is the surrounding residential wastewater collection wastewater influent COD concentration of 100 200mg L effluent chemical oxygen demand can be maintained at 20mg L can be directly water reuse This sewage treatment plant with high levels of automation can be done unattended More importantly the overall installation time investment is not high its energy consumption and waste water treatment cost is relatively low dealing with a ton of water is only 0 3 to 0 4 yuan economic efficiency is better ‘)
