Abstract
This invention discloses environmentally friendly method and apparatus for producing reverse osmosis purified water. Pre-treated original water is pressurized by a high-pressure pump, and then passes through a reverse osmosis membrane to obtain purified water that can be used. The obstructed concentrated water containing high-concentration soluble pollutants is wastewater, whose pressure is higher than that of original water. The majority of wastewater is returned to the pre-treatment apparatus by a unidirectional valve, and the minority of wastewater is discharged by an adjustment valve to keep the cleanness of the reverse osmosis membrane. Compared with present techniques, this invention has lower water consumption and higher purified water quality.
Description
Technical field
The present invention relates to a kind of pure water working method and device.
Background technology
There is two large problems in existing domestic water resources, and the firstth, famine; The secondth, water quality inferiority contains a large amount of harmful materials (like heavy metal), the life and health that seriously endangers the people.Though and existing reverse osmose pure-water production equipment can be removed filtration basically with the objectionable impurities in the water; But receive the restriction of the working process of this reverse-osmosis treated device, must consume a large amount of high slightly water of solvable harmful substance contents, prior art receives the restriction of its device structure; Can not carry out reuse to these water; Like this, though solved the quality problem of tap water, the cost of paying is to waste a large amount of water; Generally speaking, the pure water of producing 1 liter need be wasted 2.5-3.5 liters water.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of few environment-friendly water-saving type reverse osmose pure-water working method and device of water of waste.
Environment-friendly water-saving type reverse osmose pure-water working method of the present invention is achieved in that the former water of handling through pretreatment unit pressurizes through HPP, gets into reverse osmosis membrane, is spendable pure water through reverse osmosis membrane is that part of; Intercepted the higher dense water of that part of solubility harmful substance contents by reverse osmosis membrane and be waste water; Its pressure will be higher than former water pressure, and then, most waste water is back on the pretreatment unit through vacuum breaker; Small portion waste water is through the variable valve discharging, to keep the cleaning of r-o-face.Because waste water is under the cooperation of vacuum breaker and variable valve, major part is back to pretreatment unit and utilizes again, therefore, has practiced thrift a large amount of water.
Environment-friendly water-saving type reverse osmose pure-water production equipment of the present invention is to realize like this; The pre-filtering treatment facility that comprises former water; The HPP that is connected with the pre-filtering treatment facility; The reverse-osmosis filtering device that is connected with HPP, the pressure-pot that is connected with reverse-osmosis filtering device and have the depotition cock of after-treatment device, its special feature is that the wastewater outlet of reverse-osmosis filtering device is connected with the pre-filtering treatment facility through vacuum breaker and variable valve respectively.During work, pressurize through HPP, get into reverse osmosis membrane, through that part of pure water that is of reverse osmosis membrane through pretreated former water; Intercepted the higher dense water of that part of solubility harmful substance contents by reverse osmosis membrane and be waste water; Its pressure will be higher than former water pressure; Like this, through regulating variable valve, most of waste water that reverse-osmosis filtering device is come out is back on the pre-filtering treatment facility through vacuum breaker as much as possible; Simultaneously with the discharge of wastewater of another small portion, to keep the cleaning of r-o-face.Because of having adopted weighing apparatus to press HPP, guarantee that water that HPP comes out maintains in the scope of works better the pressure of reverse osmosis membrane, like this, neither influence the works better of reverse-osmosis filtering device, simultaneously, conserve water in large quantities again.
Here; For the stability of assurance device work, what HPP adopted is the constant voltage HPP, because the hydraulic pressure of constant voltage HPP output is constant; After variable valve adjusting aperture is fixed; The hydraulic pressure of the waste water that reverse-osmosis filtering device comes out also is constant, and like this, water also is constant to the applied pressure of reverse osmosis membrane in the reverse-osmosis filtering device; Thereby protected the long-term normal work of expensive reverse-osmosis filtering device, avoided hydraulic pressure fluctuated to reverse osmosis membrane detrimentally affect.
Parallel connection one automatic recoil valve on variable valve.During work; When system need make pure water, in system water process and constant voltage HPP when starting, recoil valve starts automatically; Make water wash away the reverse osmosis membrane surface after the reverse-osmosis filtering device wastewater outlet is directly drained; Like this, when having avoided the constant voltage HPP to start, unsettled hydraulic pressure is to the detrimentally affect of reverse-osmosis filtering device.
Here; The pre-filtering treatment facility is that 10 microns strainer, activated charcoal filter, pore size filter is that 5 microns strainer, ultrafilter constitutes by the pore size filter that is connected together of polyphone in regular turn, and it is between 5 microns the strainer that vacuum breaker is connected activated charcoal filter, pore size filter.Adopting multistage filter and vacuum breaker is connected activated charcoal filter, pore size filter is between 5 microns the strainer; Both can promote the clean level of current through reverse-osmosis filtering device; Promote the reverse-osmosis filtering device filtration efficiency, simultaneously, can make hydraulic pressure more constant.
The present invention compared with present technology, have the water of waste few (make 1 liter of pure water and need only discharge 0.54～0.67 liter of waste water, wastewater discharge be merely traditional way 5), the high advantage of pure water quality of being produced.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Embodiment:
Combine accompanying drawing and embodiment that the present invention is described in further detail at present:
Environment-friendly water-saving type reverse osmose pure-water working method of the present invention is achieved in that the former water of handling through pretreatment unit pressurizes through HPP, gets into reverse osmosis membrane, is spendable pure water through reverse osmosis membrane is that part of; Intercepted the higher dense water of that part of solubility harmful substance contents by reverse osmosis membrane and be waste water; Its pressure will be higher than former water pressure, and then, most waste water is back on the pretreatment unit through vacuum breaker; Small portion waste water is through the variable valve discharging, to keep the cleaning of r-o-face.
