Described ion-exchanger is sodium type and Hydrogen ion-exchanger, and sodium type and Hydrogen ion-exchanger can be that one or more levels series connection is used.
In the described chemicals dosing plant alkaline drug is housed, alkaline drug is preferably NaOH.
Described decarbonizing tower is one or more in parallel use.
Compared with the prior art, use water treatment system of the present utility model more than 97% fully to recycle water resources, and blowdown flow rate is few, need not add any chemical scale-inhibiting medicament, environmental pollution is little, environmental protection and energy saving, the fields such as reuse of water reuse and industrial circulating water in being particularly suitable for.
Below in conjunction with drawings and Examples the utility model is at length explained.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 force (forcing) pump, 2 strainers, 3 Na-ion exchangers, 4 H-ion exchangers, 5 decarbonizing towers, 6 force (forcing) pumps, 7 chemicals dosing plants, 8 accurate filters, 9 reverse osmosis high-pressure pumps, 10 reverse osmosis units, 11 reverse osmosis produced water tanks, 12 dense water tanks.
Embodiment
Referring to shown in Figure 1, be provided with force (forcing) pump 1, connect successively by pipeline and valve then strainer 2 is set, Na-ion exchanger 3, H-ion exchanger 4, decarbonizing tower 5, set up a force (forcing) pump 6 behind the decarbonizing tower 5, and then connect chemicals dosing plant 7 successively, accurate filter 8, accurate filter 8 back connect reverse osmosis high-pressure pump 9, connect reverse osmosis unit 10 through reverse osmosis high-pressure pump 9, reverse osmosis unit 10 membrane modules are made as two sections of one-levels, on reverse osmosis unit 10, connect reverse osmosis produced water tank 11 and dense water tank 12 respectively, dense water tank 12 through force (forcing) pump 13 by pipeline and valve respectively with strainer 2 and Na-ion exchanger 3, H-ion exchanger 4 connects.
Principle of work:
Former water enters strainer 2 through force (forcing) pump 1, removes suspended substance and particle in the water; Product water after process filter 2 filters is admitted to the hardness in Na-ion exchanger 3 and the H-ion exchanger 4 removal water, and the soft water after the removal hardness is delivered to decarbonizing tower 5, to remove most CO in the water
2The PH that promotes water is near neutral, product water after the decarburization is again through force (forcing) pump 6, chemicals dosing plant 7 is delivered to accurate filter 8, chemicals dosing plant 7 can be the container of a PE material or steel, the inside fills alkaline drug such as NaOH, inject product water by dosing pump through pipeline, the pH value that promotes water is 8-13, produce water and behind accurate filter 8, can remove the big particle of diameter, in order to avoid large particulate matter enters RO system (reverse osmosis unit) damage membrane element, produce water and send into reverse osmosis unit 10 (membrane module is two sections of one-levels) after by 9 superchargings of reverse osmosis high-pressure pump, reverse osmosis can remove in the water 99% salinity; The product water of reverse osmosis (be about into water 95%) is delivered in the reverse osmosis produced water tank 11 and is used as pure water, dense draining after the reverse osmosis (account for into water 5%) is stored in the dense water tank 12, the saltiness of dense draining is more than the 1000mmol/l, can be delivered in strainer 2 and the ion-exchanger through force (forcing) pump 13, can be used as the backwash water of strainer and the regenerated liquid of ion-exchanger, the overall utilization of water is reached more than 97%.
Because native system has used sodium ion and H-ion exchanger that the hardness in the water is removed, most salt is removed by reverse osmosis, simultaneously, reverse osmosis moves under high PH condition, silicon mainly is to exist with ionic species, can not pollute reverse osmosis membrane and also can remove, therefore the rate of recovery of reverse osmosis be brought up to more than 95% by reverse osmosis.And the dense draining in the dense water tank 12 (account for into water 5%) saltiness height can be 15 times of former water saltiness, can be used as the backwash water of strainer and the regenerated liquid of ion-exchanger and recycles.And the rate of recovery of its water often has only 60-70% in the existing water technology, and the sewage that remains about 30% promptly directly drained, serious environment pollution not only, and wasted great amount of water resources.Membrane module quantity in the native system reverse osmosis unit 10 can reduce to half or half multiple spot (about 3/5) quantity in the prior art in addition; and do not need film to be carried out the scale inhibition protection with the chemical scale-inhibiting medicament; not only greatly reduce cost of investment, and environmental protection, environmental pollution reduced.
Strainer 2 in the native system can use equipment such as high-efficiency fiber filter, single medium mechanical filter, two medium mechanical filter, activated charcoal filter, integral water purifier, filter.Sodium type and Hydrogen ion-exchanger can use as the series connection of the one-level among the above-mentioned embodiment, also can use according to the practical situation plural serial stage.Decarbonizing tower also can be one or more in parallel use.
