| With the continuous development of water treatment technology, the entire membrane water treatment technology becoming mature, because of its regeneration without alkali, the operation is simple, can characteristics of water, and water quality stability, application in the power plant boiler make-up water treatment technology is also increasingly widely. In recent years, the country is more and more high to the requirement of environmental protection, as a new type of fluid separation unit operation technology, represented by polymer separation membrane in the membrane separation technology, has been more and more attention in our country, especially the electric desalination technology(EDI) is one of the significant progress of water treatment technology, it not only water production of high quality and steady operation, and made from coal-fired power plants in addition to salt water thoroughly get rid of the cost of caused by using chemical regenerative agent problem, space, environment protection, etc.Through the field reconnaissance, experiment, investigation, construction project based on datang wuan power generation project will build 2 units of 300 MW indirect air cooling unit, based on the main water supply source for handan mining group guo zhuang coal mine and the second two pit mine drainage water stations underground water; Alternate source as guo zhuang coal mine and the horse of mine drainage water standing water characteristics of underground water, from the angles of suitable water treatment technology has carried on the demonstration and comparison, to determine the total membrane treatment technology and process flow and optimize the whole membrane treatment technology. Optimized system ultrafiltration, reverse osmosis, EDI equipment effluent water quality, water quantity can meet the design value, equipment operation is stable and other units in the application of the process, according to the whole film. |
