Kind is reminded；When the TDS detecting element 43 detects that TDS value reaches the second preset range, the reminding module issues second
Kind is reminded.Above-mentioned design can facilitate user to more clearly understand the water quality condition of water in water tank 41.For example, the first preset range
It is more than or equal to 20% for TDS value or greater than 50%, the second preset range is TDS value less than 20% or less than 10%, control panel
On be provided with first circulation purification mode option, second circulation purification mode option and circulation aqueous mode option, user Ke Gen
Suitable mode is selected according to the prompting that reminding module issues, has ensured that the water for obtaining meet demand, for example, when reminding module is sent out
Out when second of prompting, first circulation purification mode is may be selected in user, 41 processing system of water tank to the water in water tank 41 into
Row circulatory purification processing, to meet the needs of user is to water quality.
With reference to shown in Fig. 1 and 2, the TDS value of purified water increases with the raising of the TDS value of raw water, when the TDS value of raw water
When higher, reverse osmosis membrane filter element is because its work principle of filter determines, producing water TDS value also will appear larger situation, and TDS value is high
Producing after water flows into water tank 41 influences to drink mouthfeel, or even will appear the underproof risk of index exceeding standard, if the water in water tank 41
TDS value be in the first preset range, the present invention by increase mainly by suction pump, third control valve 72 and non-return valve 71
Before the circulation branch road 7 of composition is, it can be achieved that be evacuated to stabilized pressure pump 22 for the water in water tank 41, pass through reverse osmosis treatment again, realizes water
The TDS value of water in case 41 is in compared with low state, achievees the effect that " extremely pure ", preferably to meet the needs of users.
It should be noted that with reference to shown in Fig. 1 and 2, in first circulation purification mode, the recycling of the water treatment system
Rate has the feature of rate of recovery when being more than or equal to conventional water processed compared with the conventional rate of recovery during water production, and peak is reachable
90% or more, the control of the rate of recovery at this time can be by a plurality of waste discharge branch 6 in parallel or by adjusting the second control valve 61 and giving up
Water is controlled than the switch time of solenoid valve 62, and preferred embodiment is the latter, and as escribed above first controls stage, the second control
Stage processed and third control stage etc..In addition, reverse osmosis membrane is consequently increased through the amount of salt under high-recovery operating condition, influence
The TDS value for producing water carries out osmosis filtration by circulation, it is ensured that the TDS value of the water in water tank 41 meets twice or repeatedly
It is required that.
With reference to shown in Fig. 1 and 2, the water treatment system of the application passes through the design of circulation branch road 7, and water tank 41 may be implemented
In purified water circulation flushing reverse osmosis membrane filter element in reverse osmosis membrane, the shearing force of high flow rate is utilized in circulation flushing process
With the high solubility of purified water.Film surface can build up various pollutants matter in reverse osmosis membrane operational process, cause reverse osmosis
The pollution of film is until failure.Contain few ion and organic matter in purified water, so having very strong solubility property.Pass through
The effect that flow field stable state is destroyed using the high shear of purified water and high dissolving power and pulse, may be implemented negative margin
Layer slows down reverse osmosis membrane concentration polarization phenomenon, to extend the service life of reverse osmosis membrane filter element.A kind of typical circulation flushing process
For, 6 not effluent of circulation flushing waste discharge early period branch, the purified water extracted from water tank 41 rinses reverse osmosis membrane high speed,
Under the action of shearing force and dissolving power, the amount of pollutant accumulation of film surface is gradually reduced, this stage is the first above-mentioned control rank
Section.After the first control stage continuous service 300 seconds, into the second control stage, 6 pulse type emission of waste discharge branch is useless at this time
The pulse type emission of water, waste water can further abolish pulsatile flow field, further increase the effect of circulation flushing, finally will storage
Water in water installations 4 is all purified again, with brand-new water full of water tank 41 and purifying flow path 2, circulation and pulse waste discharge
The process of water can be the permutation and combination form of single or multiple processes.In addition, this water treatment system and conventional water tank 41
Manual blowdown design in bottom is compared, and the present invention realizes 41 function of automatic washing water tank by suction pump, circulation flushing, waste discharge design
Energy.
The application also proposes a kind of purifier, such as water purifier, which applies above-mentioned water treatment system.
It can guarantee water quality indicator when water purifier uses under severe water quality area or high-recovery state by above-mentioned design, it is ensured that
The normal use of purifier.
Those skilled in the art will readily recognize that above-mentioned each preferred embodiment can be free under the premise of not conflicting
Ground combination, superposition.
It should be appreciated that above-mentioned embodiment is merely exemplary, and not restrictive, without departing from base of the invention
In the case where present principles, those skilled in the art can be for the various apparent or equivalent modification that above-mentioned details is made
Or replacement, all it is included in scope of the presently claimed invention.
