Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in fig. 1, a dense water utilization system of water making equipment of power plant, including former water tank, collect the dense water of second grade reverse osmosis, former water tank links to each other with the multi-media filter pipeline, the multi-media filter links to each other with two sets of activated carbon filter (two sets of series connection) pipelines, activated carbon filter links to each other with one-level reverse osmosis pipeline, one-level reverse osmosis links to each other with utmost point water tank pipeline, utmost point water tank is used for collecting the concentrated water of DEI electrodialysis, utmost point water tank links to each other with second grade reverse osmosis pipeline, makes the dense water get into former water tank, second grade reverse osmosis links to each other with middle water tank pipeline, middle water tank links to each other with DEI electrodialysis pipeline, and the dense water gets into utmost point water tank, DEI electrodialysis links to each other with desalination water tank pipeline, desalination water. Connecting concentrated water which is generated by the secondary reverse osmosis and is discharged into a trench to a raw water tank by a pipeline; concentrated water produced by the DEI electrodialysis and discharged into a trench is connected to the polar water tank by a pipeline. Meanwhile, a bypass is connected to the second-stage reverse osmosis concentrated water pipeline, concentrated water is not required to be recovered, a bypass valve is opened, and the bypass valve is closed when concentrated water is required to be recovered. The concentrated water pipeline of the DEI electrodialysis is the same as the second-stage reverse osmosis.
The concentrated water recovery principle of the secondary reverse osmosis and the concentrated water recovery principle of the DEI electrodialysis aim at that the concentrated water of the secondary reverse osmosis and the concentrated water of the DEI electrodialysis have certain pressure when equipment is used for producing water, and in order to make full use of the energy, extra energy consumption is not increased. The concentrated water of the two reverse osmosis systems and the DEI electrodialysis concentrated water are introduced into the raw water tank and the polar water tank by utilizing the pressure, the produced water quality is far greater than the water quality of the raw water quality and the polar water quality, and the purpose of saving water is achieved, so that the energy conservation and emission reduction are realized, the utilization rate of the water is improved by the mode, and the operation load of the reverse osmosis membrane is reduced.
The yield of the second-level reverse osmosis concentrated water is about 40 cubic meters per day, the conductivity of the concentrated water is about 0.7, and the hardness is about 3 umol/l. DEI electrodialysis: the yield per day was about 5 cubes, the conductivity of the concentrate was about 0.5 and the hardness was about 1 umol/l. The discharged concentrated water contains only the impurity components of the feed water, and the quality of the water is generally better than that of the feed water of the pretreatment system. Therefore, the concentrated water can be directly recovered to the raw water inlet of the RO, thereby effectively eliminating the discharge of the waste water.
