Description of the drawings
Fig. 1 is the composition schematic diagram of the water treatment facilities of the water purifier automatic backwash of the present invention.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples, and the content of embodiment is not as the guarantor to the present invention
Protect the limitation of range.
Fig. 1 shows the composition schematic diagram of the water treatment facilities of the water purifier automatic backwash of the present invention.Such as Fig. 1 institutes
Show, the water treatment facilities of water purifier automatic backwash of the invention includes fore filter 1.The fore filter 1 into
The mouth of a river is connected with raw water water inlet.The fore filter 2 is used for entering the raw water in it by the raw water water inlet
It is filtered for the first time, by the soil in raw water, the larger substance of the particles such as impurity filters out.
The water outlet of the fore filter 1 is connected with the water inlet of ultrafilter 5 and the fore filter 1 goes out
Low tension switch 2 is equipped between the mouth of a river and the water inlet of the ultrafilter 5.The low tension switch 2 when anhydrous for controlling
The water treatment facilities is shut down.The ultrafilter 5 is used to carry out secondary filter to 1 filtered water of the fore filter,
By the soil in further filtering out, the larger substance of the particles such as impurity.
The water outlet of the ultrafilter 5 is connected with the water inlet of RO membrane filters 9 and the ultrafilter 5 goes out
Motor 7 is equipped between the mouth of a river and the water inlet of the RO membrane filters 9.The density of the RO films of the RO membrane filters 9 is relatively low, needs
Intensified pressure can just pass water through, and play the effect of refined filtration.And the motor 7 is then used for entering the RO membrane filters 5
Water is pressurized, in order to which it can pass through the RO films.Wherein, water is entered by some after the RO films in film
Chamber, some cannot be introduced into film inner cavity, the water purification after being refined filtration into film inner cavity, and the water for not entering film inner cavity is waste water.
The water purification outlet of the RO membrane filters 9 is connected with the water inlet of postposition carbon filter 13 and the RO membrane filters
High-voltage switch gear 12 is equipped between 9 water purification outlet and the water inlet of the postposition carbon filter 13.The high-voltage switch gear 12 is used for
The water treatment facilities is controlled when 14 water of aftermentioned water tank is full to shut down.Water purification after 9 refined filtration of RO membrane filters enters institute
It is for re-filtering to state postposition carbon filter 13.The major function of the postposition carbon filter 13 is to improve mouthfeel.
The water outlet of the postposition carbon filter 13 is connected with the water inlet of water tank 14.By the postposition carbon filter 13
Improve the pure water after mouthfeel to be stored into the water tank 14, in order to use.
The wastewater outlet of the RO membrane filters 9 is connected with the water inlet of the ultrafilter 5.Through the RO membrane filtrations
Secondary filter is carried out in Sewage treatment afterwards to the ultrafilter 5.
Meanwhile being additionally provided with scouring electromagnetic valve 6 in the ultrafilter 5.When the ultrafilter 5 works after ten minutes
It can be backwashed, it is, ultrafiltration of the water to the ultrafilter 5 of the Sewage treatment using the RO membrane filters 9
Film is rinsed.In the present invention, waste water flushing usage amount and the pure water of production are 1: 2, keep water treatment system discharge of wastewater few, reach
To micro- waste water.
Preferably, raw water pressure gauge 3 and institute are equipped between the low tension switch 2 and the water inlet of the ultrafilter 5
State pressure gauge 8 before being equipped with film between motor 7 and the water inlet of the RO membrane filters 9.Wherein, the raw water pressure gauge 3 is used for
Monitor raw water pressure, it is ensured that the enough water treatment facilities of pressure use.Pressure gauge 8 is suppressed for monitoring the motor 7 before the film
Actual numerical value afterwards, to better use water treatment facilities.Also, just by pressure gauge 8 before the raw water pressure gauge 3 and film
In the supercharging for determining the motor 7.
It is highly preferred that being equipped with the first non-return valve 4 between the raw water pressure gauge 3 and the water inlet of the ultrafilter 5.
By first non-return valve 4, in the return of waste water to the fore filter 1 that the RO membrane filters 9 can be prevented.
More preferably, the is equipped between the wastewater outlet and the water inlet of the ultrafilter 5 of the RO membrane filters 9
Two non-return valves 10.By second non-return valve 10, it can prevent the fore filter 5 filtered water adverse current from arriving the RO
The waste water intracavitary of membrane filter 9.
Finally, it is preferable that third check is equipped between the water purification outlet and the high-voltage switch gear 12 of the RO membrane filters 9
Valve 11.By institute's third non-return valve 11, it can prevent the water adverse current in the postposition carbon filter 13 from arriving the RO membrane filters 9
In.
The water treatment facilities of the water purifier automatic backwash of the present invention can realize the auto-flushing of ultrafiltration membrane, greatly prolong
The service life of ultrafiltration membrane, reduces cost.Moreover, which reduce the use of disposable element, it is more environmentally-friendly, and cost is more
It is low.Meanwhile which solve use ultrafiltration membrane to purify the confinement problems for being not thorough and being unsuitable for the north and use when being purified.Most
Afterwards, the filter membrane of ultrafilter is rinsed using the water of RO membrane filter Sewage treatments, waste water flushing usage amount with
The pure water of production is 1: 2, keeps water treatment facilities discharge of wastewater few, reaches micro- waste water.
The above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to the present invention
Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description
