Technical field
Present technique relates to a kind of water treatment device.
Background technology
Existing water treatment device generally comprises topping-up pump, filtration unit, high-pressure pump, the reverse osmosis unit of connecting successively by pipeline.
Reverse osmosis unit belongs to prior art, generally comprise the reverse osmosis housing, be positioned at the housing two ends end cap, be arranged on the reverse osmosis membrane of reverse osmosis housing, the two ends of reverse osmosis membrane have formed former water cavity and concentrated sap cavity respectively and between two end caps; One end of penetrating fluid pipe extend in the reverse osmosis film body, and the other end passes concentrated sap cavity and stretches out end cap, extend on the tube wall of the penetrating fluid pipe in the reverse osmosis film body and has through hole.Reverse osmosis claims again reverse osmosis, and is a kind of take pressure difference as impellent, isolates the membrane sepn operative technique of solvent from solution.The former water that passes through former water cavity to film one side is exerted pressure with high-pressure pump, and when pressure surpassed its osmotic pressure, solvent can be made inverse osmosis against the direction of naturally osmotic.Thereby the solvent that obtains seeing through in the low-tension side of film, i.e. penetrating fluid, penetrating fluid flows out by the penetrating fluid pipe.The solution that obtains concentrating (concentrated solution) collects in the contracting sap cavity.If use the reverse-osmosis treated seawater, obtain fresh water in the low-tension side of film, obtain bittern in the high-tension side.
But this water treatment device generally all only has the first-stage reverse osmosis device at present, and by the water outlet that this water treatment device obtains, its specific conductivity is higher, generally at 10-40us/cm(25 ℃) between.
Summary of the invention
The purpose of present technique provides a kind of lower water treatment device of specific conductivity that can obtain effluent quality.
This water treatment device, comprise topping-up pump, filtration unit, one-level high-pressure pump, first-stage reverse osmosis device, secondary high-pressure pump, the second level reverse osmosis apparatus of connecting successively by pipeline, the pipeline between first-stage reverse osmosis device and second level reverse osmosis apparatus arranges the pH value adjusting device.
The beneficial effect of present technique: the utility model pH value adjusting device is regulated the pH value (being generally pH=8.3) of second level reverse osmosis apparatus water inlet, with CO
2Be converted into HCO
3-, remove HCO by second level reverse osmosis apparatus
3-, reduce CO thereby reach
2Content; In addition, be in series by first-stage reverse osmosis device and two reverse osmosis units of second level reverse osmosis apparatus, the specific conductivity that has further guaranteed effluent quality generally between 1-10us/cm, is suitable for use as drinks manufacturing and degree of falling water; The preparation in early stage of the industry waters such as medicine, electronics; Concentrated, the separation of chemical technique, purification and water distribution preparation; The industry waters such as papermaking, plating, printing and dyeing.
Above-mentioned water treatment device, described filtration unit comprise activated charcoal filter, the cartridge filter that is in series, and scale inhibitor feeding device is arranged on the pipeline between activated charcoal filter and the cartridge filter.Preferably, the pipeline before activated charcoal filter is provided with the reductive agent throwing device.Best, described filtration unit also comprises high efficiency filter, washed ore strainer, and high efficiency filter, washed ore strainer, activated charcoal filter are connected successively, and the reductive agent throwing device is arranged on the pipeline between washed ore strainer and the activated charcoal filter.More preferably, the pipeline before high efficiency filter is provided with flocculating agent feeding device and sterilant throwing device.
Scale inhibitor feeding device can stop the fouling of vitriol, to prevent that the materials such as calcium sulfate are to the harm, particularly BaSO of reverse osmosis membrane
4And SrSO
4The crystallization crystal has improved the work-ing life of native system to the harm of reverse osmosis membrane.Utilize gac to remove low molecule organic matter in the water, free chlorine effectively prevents the Organic pollutants on reverse osmosis membrane surface and the permanent damage that free chlorine causes reverse osmosis membrane.Because general reverse osmosis membrane is made by the aromatic polyamides composite membrane, resistance to oxidation can not reduced the oxidisability in the water by adding reductive agent, to protect reverse osmosis membrane operation steady in a long-term.Utilize the filtrates such as quartz sand can remove suspended substance in the former water by the washed ore strainer.In former water, drop into flocculation agent, the suspended particulates in the solution assemble to connect are formed thick cotton-shaped or agglomerate, make colloid in the water and mechanical particle can be filtered device and more effectively remove.
