Other embodiment such as: a RO membrane module 70 arranges N RO film sub-component, and the 2nd RO membrane module arranges N RO film sub-component. Wherein, N is integer.
More specifically, filter type switching construction comprises the first valve 74, the second valve 75 and the 3rd valve 76, the delivery port of multistage pump 50 is communicated with the dense water inlet of a RO membrane module 70 and the water inlet of the first valve 74, the delivery port of the first valve 74 is communicated with the dense water inlet of the 2nd RO membrane module 71 and the water inlet of the second valve 75, the pure water outlet of the one RO membrane module 70 is communicated with delivery port and the 3rd valve 76 of the second valve 75, and the delivery port of the 3rd valve 76 is communicated with the pure water outlet of the 2nd RO membrane module 71.
Wherein, prefilter is for bulky grain floating thing, fine particles, organic matter and the ionic impurity of filtering running water. RO membrane filtration structure coordinates with multistage pump 50, realizes the counter-infiltration of former water.
Cartridge filter 60 is for holding back the particle that is greater than 5 μ m of former water, in former water, larger particle very easily scratches the desalination epidermal area on reverse osmosis (RO) film surface after multistage pump 50 accelerates, even may puncture reverse osmosis (RO) membrane module, by cartridge filter 60 being set to ensure that reverse osmosis membrane is not scratched by oarse-grained suspension; Another effect while being exactly the filter core place by cartridge filter 60, can make the abundant hybrid reaction of reducing agent with in and oxidant.
In addition, the dense water out of a RO membrane module 70 is flowed through after a concentrated stream amount meter 73 and is communicated with discharge of wastewater pipeline 30 after check-valves, and the high concentrated water drainage of salinity that contains that a RO membrane module 70 is discharged goes out.
Mode of operation is as follows:
Open the first valve 74 and the 3rd valve 76, close after the second valve 75, the dense water inlet of a RO membrane module 70 and the 2nd RO membrane module 71 is communicated with the delivery port of multistage pump 50 simultaneously, and pure water significantly increases. From flowing out, the pure water outlet of a RO membrane module 70 and the 2nd RO membrane module 71 draws through the pure water interface 51 of pipeline.
Close the first valve 74 and the 3rd valve 76, open after the second valve 75, the pure water outlet of a RO membrane module 70 is communicated with the dense water inlet of the 2nd RO membrane module 71, and by this kind of mode, the present invention can realize the counter-infiltration of two-stage RO membrane module, and the water quality of pure water is better.
Under the operation of normality pure water, the 7th valve 22 and the 8th valve 23 are all in closed condition. In the time that the 7th valve 22 is opened, can be communicated with water inlet and the liquid medicine case 21 of booster pump 20, liquid medicine can be imported to prefilter by the supercharging of booster pump 20, the impurity accumulation in prefilter is cleaned.
More preferably, the present invention is communicated with filtering tank 40 cavity volumes and the discharge of wastewater pipeline 30 in prefilter by pipeline and check-valves successively, and on pipeline, is provided with control valve. After fully impurity accumulation is dissolved in reaction in pre-filtering cavity volume until liquid medicine, this control valve is opened, can very easily the waste water after cleaning be discharged by discharge of wastewater pipeline 30.
Taking the preferred embodiment of the present invention as example, in the time opening the 8th valve 23 and the first valve 74, the liquid medicine outlet of liquid medicine case 21 is communicated with the dense water out of the 2nd RO membrane module 71. When backwash operation, liquid medicine flows into the dense water inlet from the 2nd RO membrane module 71 again from the dense water out of the 2nd RO membrane module 71 and flows out, the dense water inlet from a RO membrane module 70 again of flowing through after the first valve 74 flows into, after fully impurity accumulation is dissolved in reaction in pre-filtering cavity volume until liquid medicine, finally import discharge of wastewater pipeline 30 from the dense water out of a RO membrane module 70.
Further, the shell of a RO membrane module 70 and the 2nd RO membrane module 71 is all coated with heating plate. Suitably improve the temperature of RO film sub-component by heating plate, can significantly promote the pure water filtration and infiltration ability of RO film, further improve pure water productive rate and produce speed.
Further, multiple purifying pure water equipment also comprises and the matching used grug feeding jar of liquid medicine case 21 and drug metering device, drug metering device is also electrically connected an input unit and display unit, input unit is used for inputting dosage control command, and drug metering device is used for according to dosage control command dosage measuring medicament.
In the time that needs carry out backwash to multiple purifying pure water equipment of the present invention, can be for the use duration of the clean degree of raw water quality and multiple purifying pure water equipment, by the metering of input unit control drug metering device, science is selected drug dose, both ensure equipment backwash cleannes, saved again liquid medicine.
Further, prefilter comprises filtering tank 40, and filtering tank 40 comprises the first order filtering tank 40, second level filtering tank 40 and the third level filtering tank 40 that are communicated with successively by pipeline. By three-stage filtration tank 40 is set, filter effect of the present invention is better.

Alternatively, between multistage pump 50 and RO membrane filtration structure, be provided with high voltage protective switch 53, high voltage protective switch 53 ends pipeline while transfiniting for the hydraulic pressure in pipeline. By this kind of mode, effectively to avoid, because the hydraulic pressure in pipeline is too high, multistage pump 50 and RO membrane module are produced to irreversible damage, guarantee system is safe and reliable to operation.
Further, between the water inlet of multistage pump 50 and delivery port, be communicated with by an external pipe, and one the 6th valve 79 is set on external pipe. If open this 6th valve 79, do not need multistage pump 50 to work and also can realize the pure water operation to running water. In for the good situation of raw water quality, can open this 6th valve 79, reduce energy consumption.
In addition, the water inlet of booster pump 20 is communicated with the running water outlet of raw water box 90, and raw water box 90 is for buffering and carry out ground floor water contamination precipitation.
Alternatively, the present invention is communicated with filtering tank 40 cavity volumes and discharge of wastewater pipeline 30 by pipeline and check-valves successively, and on pipeline, is provided with control valve. Control valve is opened, can be carried out backwash operation to filtering tank 40. When the impurity of institute's accumulation is too much on the fillers such as the interior sand body of filtering tank 40, active carbon or resin, can pass through this kind of mode backwash, to realize the repetition regeneration of filtering tank 40, cost-saving.
More preferably, 10 places, the external mouth of a river from the beginning also connect a raw water box 90, in raw water box 90, be provided with the Level meter being electrically connected with booster pump 20, Level meter is for generating leve signal correspondingly according to the water level in raw water box 90, and booster pump 20 is automatically out of service when presetting safety value at leve signal. More specifically, this Level meter comprises Floating Ball Liquid Level detector. By this kind of mode, can avoid raw water box 90 interior water shortage time, there is fast idle and produce infringement in booster pump 20.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations. Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
