Power Plant
Main use reverse osmosis technology
1 power plant cooling water treatment
Power plants in operation in the process of the need to consume large amounts of water circulating cooling effect, if carried out in accordance with the requirements of environmental protection will use the waste water after the treatment, will undoubtedly increase power plant operating costs and the emergence of reverse osmosis technology can realize the recycling use of waste water in power plant, the purification of waste water in power plants can be effect, improve power plant waste water quality, can supplement sufficient water for circulating cooling system, to realize the idea of combining economic and ecological benefits.
2 For power plant boiler pickling waste liquor treatment
Power plant boiler operation in operation process can produce a kind of waste liquid, said boiler pickling waste liquor, for boiler pickling waste liquor processing, selecting the different material of membrane to deal with waste liquid simulation experiment, finally the experimental results show that all of the processing results, the water film is best for liquid waste processing, so choose the water film, as a reverse osmosis membrane process, boiler produced by pickling waste liquor can effectively improve waste recycling, in the presence of reducing environmental pollution is a new progress.
3 Power plant wastewater treatment operation
Each link in the operation of the power plant will use a lot of water, at the same time also can produce different kinds of wastewater, such as acid and alkali waste water, sewage, and flush the field produced by the waste water, this kind of waste water is acidic, for the power plant of wastewater treatment, must first to make weak acid waste water treatment, to promote the utilization of the waste water, meet the needs of the power plant water.
Because in the process of reverse osmosis treatment concentration of suspended particles in water and soluble substances continuous increase, cause the volume of water becomes more and more small, the suspended material in constant deposition, reverse osmosis membrane mountain, in turn, has congestion on the feed water flow, the friction also gradually increased. At the same time, the strong increase in the number of salt material difficult to dissolve in the water reaches a certain amount will be after deposition, reverse osmosis membrane surface fouling caused this kind of problem will lead to reverse osmosis membrane by light becomes smaller, the operation pressure and friction resistance can cause water quality produce. Even for the above reason cause reverse osmosis membrane pollution case, in view of this situation should increase the pretreatment process, to reduce the suspended solids, organic matter. Difficult to dissolve salt material for reverse osmosis membrane and so on, the phenomenon of pollution, improve the durability of reverse osmosis membrane and improve water quality. Before selecting raw water into the reverse osmosis device with pretreatment in the system each add more media filtration systems, security filters, activated carbon filter, filter and at the same time in order to avoid losing effect should be more media filter and activated carbon filter material to replace regular cleaning, with the aid of the function of the filter, for the water soluble substances and organic matter removal, to reduce COD content in water. Backwashing for security filters, regularly and ultrasonic processing, can effectively reduce the bacterial growth and magazine sedimentary formation, in order to avoid short replacement cycle time and cost of the 15t waste recommended h1T1) filter source filter area, reduce the cycle replacement time is short, also can reduce the cost of demand.
