For the preferred embodiment of the present invention, when opening the 8th valve 23 and the first valve 74, namely the liquid medicine outlet of liquid medicine case 21 is communicated with the dense water out of the 2nd RO membrane module 71.During backwash operation, liquid medicine flows into from the dense water out of the 2nd RO membrane module 71 and flows out from the dense water inlet of the 2nd RO membrane module 71, dense water inlet again from a RO membrane module 70 after flowing through the first valve 74 flows into, after fully impurity accumulation is dissolved by 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, reverse osmose 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 for inputting dosage control order, and drug metering device is used for according to dosage control order dosage measuring medicament.
When needs carry out backwash to reverse osmose pure-water equipment of the present invention, can totally spend the use duration with reverse osmose pure-water equipment for raw water quality, be controlled the metering of drug metering device by input unit, science selects drug dose, both ensure that equipment backwash degree of cleaning, again save liquid medicine.
Further, prefilter comprises hay tank 40, and hay tank 40 comprises the first step hay tank 40, second stage hay tank 40 and the third stage hay tank 40 that are communicated with successively by pipeline.By arranging three-stage filtration tank 40, filter effect of the present invention is better.
More specifically, the tank body cavity volume of hay tank 40 is divided into top area, media areas and lower region.
Further, the top area of first step hay tank 40 and lower region place coarse sand, and fine sand is placed in the media areas of first step hay tank 40; The top area of second stage hay tank 40 and lower region place thick carbon, and thin carbon is placed in the media areas of second stage hay tank 40; The top area of third stage hay tank 40, media areas and lower region all place resin.
Wherein, coarse sand and fine sand are for the colloid in trap water and particulate.Thick carbon and thin carbon can free chlorine, organism and smells effectively in filtering tap water.Resin is free on negatively charged ion in tap water and positively charged ion for taking out.Alternatively, coarse sand can replace with hard coal, and effect is better.
The present invention's layering in tank body is filled for the sand body that filters and gac, and the structure proportioning using thickness to combine can the impurity such as particle more effectively in adsorption filtration tap water and suspended substance.
Alternatively, hay tank 40 of the present invention also comprises decarbonate hay tank 40, is dissolved in the carbonic acid gas in tap water in order to filtering.
Further, arrange dividing plate in the tank body cavity volume of hay tank 40, top and the perisporium of dividing plate and tank body cavity volume are tightly connected, and form left chamber and right chamber, left chamber is communicated with bottom tank body cavity volume with right chamber.By this kind of mode, tap water need could flow into right chamber after the water-in of hay tank 40 flows into left chamber bottom cavity volume, extends the filtration path of tap water in hay tank 40 at double and filters duration, making impurity more thorough by adsorption filtration.
Alternatively, RO membrane filtration structure is provided with vacuum breaker at pure water interface 51 place and is communicated with pure water under meter 72 with vacuum breaker, and vacuum breaker flows backwards for limiting pure water.The present invention can effectively suppress pure water to flow backwards by vacuum breaker, and pure water under meter 72 is for measuring the flow of pure water to carry out Statistical monitor.
Simultaneously, the dense water out of the one RO membrane module 70 is communicated with the water-in of the 4th valve 77, the water outlet of the 4th valve 77 is communicated with the water-in of the 5th valve 78 with the dense water out of the 2nd RO membrane module 71,5th valve 78 is communicated with the water-in of stage pump 50, forms the dense water recovery culvert 52 of second stage film.
After carrying out first step Pure water preparation, the dense water salinity of discharging from the dense water out of the 2nd RO membrane module 71 is very low, can reclaim use, not only can be caused water resources serious waste as directly discharged but also pollute the environment.The dense water of lower concentration that dense water out from the 2nd RO membrane module 71 is discharged to be rebooted the water-in to stage pump 50 by the dense water recovery culvert of second stage film 52 by the present invention, by this kind of mode, the pure water producing water ratio that significantly improve tap water can reduce again the pollution to environment.
Concrete operations mode is as follows:
Close the 4th valve 77, open the 5th valve 78, can by the dense water recovery culvert 52 of connection second stage film.
Alternatively, between stage pump 50 and RO membrane filtration structure, be provided with high voltage protective switch 53, when high voltage protective switch 53 transfinites for the hydraulic pressure in pipeline, end pipeline.By this kind of mode, effectively avoid because the hydraulic pressure in pipeline is too high and irreversible damage is produced to stage pump 50 and RO membrane module, ensureing that system cloud gray model is safe and reliable.
Further, be communicated with by an external pipe between the water-in of stage pump 50 and water outlet, and external pipe arranged one the 6th valve 79.If open this 6th valve 79, then stage pump 50 pure water that also can realize tap water that works is not needed to operate.For in the good situation of raw water quality, this 6th valve 79 can be opened, reduce energy consumption.
In addition, the water-in of topping-up pump 20 and the tap water outlet of raw water box, raw water box is used for buffering and carries out the first layer impurities in water precipitation.
Alternatively, the present invention is communicated with hay tank 40 cavity volume and discharge of wastewater pipeline 30 by pipeline with vacuum breaker successively, and is provided with variable valve on pipeline.Variable valve is opened, backwash operation can be carried out to hay tank 40.When in hay tank 40, on the weighting material such as sand body, gac or resin, the impurity of institute's accumulation is too much, namely by this kind of mode backwash, to realize the repetition regeneration of hay tank 40, cost-saving.
More preferably, the external mouth of a river from the beginning 10 place also connects a raw water box, the Level meter be electrically connected with topping-up pump 20 is provided with in raw water box, Level meter be used for generate corresponding leve signal according to the water level in raw water box, topping-up pump 20 at leve signal lower than automatically out of service during preset security value.More specifically, this Level meter comprises Floating Ball Liquid Level detector.By this kind of mode, when can avoid water shortage in raw water box, there is fast idle and produce infringement in topping-up 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 done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
