Abstract
The invention discloses a water purifying process for purifying water body through a purifying device. The purifying device comprises a water inlet, a purifying membrane group for purifying the water body, a water producing opening for discharging purified water and a water outlet for discharging concentrated water, wherein the purifying membrane group comprises two or more than two purifying membranes connected in series. According to the process, the water body is controlled to flow from the water inlet of the purifying device to the water outlet of the purifying device and flow from the water outlet of the purifying device to the water inlet of the purifying device, and the directions in which the water body flows into and out of the purifying device are controlled to be changed intermittently. The purifying membranes at the back section can be used as the purifying membranes at the front section in the process, the sewage blocking possibility of the purifying membranes is lowered, the chemical cleaning cost caused by sewage blocking of the purifying membranes is reduced, and the service life of the purifying membranes is prolonged.
Description
Technical field
the present invention relates to a kind of water-purifying process.
Background technology
existing water-purifying process, be generally that purification membrane group is arranged in refining plant by purification membrane group purifying water body, water body enters from the water-in of refining plant, and dense water is discharged from the water outlet of refining plant.Multiple purification membrane series arrangement forms purification membrane group, the dense water that leading portion purification membrane produces is as the water inlet of back segment purification membrane, the saltiness of intaking in purification membrane flows to along water body and uprises gradually, therefore the pollution near the back segment purification membrane of water outlet is relatively faster, dirty stifled probability is higher, and the work-ing life of back segment purification membrane is shorter than the work-ing life of leading portion purification membrane.
Summary of the invention
the object of this invention is to provide a kind of water-purifying process, improve the work-ing life near the purification membrane of water outlet in refining plant.
for achieving the above object, the technical solution used in the present invention is:
a kind of water-purifying process, by refining plant purifying water body, described refining plant comprise water-in, for purifying water body purification membrane group, for discharge water purification the product mouth of a river, for discharging the water outlet of dense water, described purification membrane group comprises at least two purification membrane be arranged in series, and described water-purifying process comprises the following steps:
(1) pass into described refining plant by water body from described water-in, water body flows through described purification membrane group along described water-in toward the direction of described water outlet, and the water purification that purification produces is discharged from the described product mouth of a river, and dense water is discharged from described water outlet;
(2) inflow direction of water body is changed, water body is passed into described refining plant from described water outlet, water body flows through described purification membrane group along described water outlet toward the direction of described water-in, and the water purification that purification produces is discharged from the described product mouth of a river, and dense water is discharged from described water-in;
(3) step (1) and step (2) is alternately repeated, to complete the purification to water body.
preferably, described refining plant arranges Controlling System, described Controlling System flows through the direction of described refining plant for controlling the intermittent change of water body.
preferably, described purification membrane comprises reverse osmosis membrane and/or nanofiltration membrane and/or ultra-filtration membrane.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: present invention process flows to water outlet by controlling water body from the water-in of refining plant, flows to water-in from the water outlet of refining plant again, controls the direction of water body intermittent change inflow and outflow refining plant.Back segment purification membrane also can be used as leading portion purification membrane in process, and probability is blocked up in the dirt reducing purification membrane, reduces the matting expense produced because purification membrane dirt is stifled, the work-ing life extending purification membrane.
Accompanying drawing explanation
accompanying drawing 1 is in the schematic diagram of the first running status for an embodiment of the present invention;
accompanying drawing 2 is in the schematic diagram of the second running status for an embodiment of the present invention.
wherein: 1, water-in; 2, is produced from the mouth of a river; 3, water outlet; 4, the first purification membrane; 5, the second purification membrane; 6, the 3rd purification membrane.
Embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Fig. 1-2, above-mentioned a kind of water-purifying process, by refining plant purifying water body.This refining plant comprise water-in 1 for passing into water body, for purifying water body purification membrane group, for discharge water purification the product mouth of a river 2, for discharging the water outlet 3 of dense water.In the present embodiment, this purification membrane group comprises three purification membrane be mutually arranged in series, and is followed successively by the first purification membrane 4, second purification membrane 5, the 3rd purification membrane 6 along water-in toward the direction of water outlet.This purification membrane is reverse osmosis membrane.This water-purifying process comprises the following steps:
(1) water body is passed into refining plant from water-in 1, water body flows through three reverse osmosis membranes successively along water-in 1 toward the direction of water outlet 3, after water body flows through the first purification membrane 4, the water purification that first purification membrane 4 purifies is discharged from the product mouth of a river 2, the water purification that dense water continues to flow through the second purification membrane 5, second purification membrane 5 purification is discharged from the product mouth of a river 2, and dense water continues to flow through the 3rd purification membrane 6, the water purification that 3rd purification membrane 6 purifies is discharged from the product mouth of a river 2, and dense water is then discharged from water outlet 3.
(2) Controlling System is set on refining plant, this Controlling System changes the inflow direction of water body, water body is made to pass into refining plant from water outlet 3, water body flows through three reverse osmosis membranes successively along water outlet 3 toward the direction of water-in 1, after water body flows through the 3rd purification membrane 6, the water purification that 3rd purification membrane 6 purifies is discharged from the product mouth of a river 2, dense water continues to flow through the second purification membrane 5, the water purification that second purification membrane 5 purifies is discharged from the product mouth of a river 2, dense water continues to flow through the first purification membrane 4, the water purification that first purification membrane 4 purifies is discharged from the product mouth of a river 2, and dense water is then discharged from water-in 1.
(3) step (1) and step (2) is alternately repeated, to complete the purification to water body.
above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
