Abstract
The utility model discloses two-stage reverse osmosis water purification equipment and relates to water treatment equipment, in particular to reverse osmosis water treatment equipment. The two-stage reverse osmosis water purification equipment comprises a pretreatment water tank (1) containing pretreated water, a primary water pump (2), primary reverse osmosis membrane equipment (3), a primary water tank (4), a secondary water pump (5), secondary reverse osmosis membrane equipment (6) and a purified water tank (7), wherein the primary water pump (2) is connected between the pretreatment water tank (1) and the primary reverse osmosis membrane equipment (3); an outlet of the primary reverse osmosis membrane equipment (3) is communicated with the primary water tank (4); the secondary water pump (5) is connected between the primary water tank (4) and the secondary reverse osmosis membrane equipment (6); and an outlet of the secondary reverse osmosis membrane equipment (6) is communicated with the purified water tank (7). The two-stage reverse osmosis water treatment equipment solves the problem that although current industrial wastewater is treated, the water quality is difficult to meet the purification requirement of the associated industry.
Description
Technical field
The utility model relates to water treating equipment, is specifically related to the reverse-osmosis treated wetting system.
Background technology
In fields such as biology, medicine, electronics, plating, can produce a lot of waste water in the production.Its water quality is different because of production technique, and what have contains chromium, have nickeliferous or contain cadmium, contain cyanogen, contain acid, contain alkali etc.Some of metal ions in waste water in a simple cation forms exist (eg Ni2 +, Cu2 +, etc.), some in the form of anions (such as CrO, etc.), some take a complex form of complex anions such as [Au (CN ) Entertainment, Cd (CN) An, Cu (P2O7) Yong, etc.].
Method of wastewater treatment commonly used at present is an ion exchange method; Though can handle to waste water; But the water quality after handling still is difficult to reach the purifying requirement of related industries, and it is high that the water after these are handled contains acid, can not return production and utilize; Cause soda acid relief liquor contaminate environment, and the waste problem of water resources.
The utility model content
The utility model provides a kind of two-pass reverse osmosis purified water equipment, though the utility model has solved present trade effluent through handling, water quality still is difficult to reach the problem that the purifying of related industries requires.
For addressing the above problem, the utility model adopts following technical scheme: two-pass reverse osmosis purified water equipment comprises the pre-treatment water tank 1 that is loaded with pretreated water; Also comprise one-level water pump 2, first-stage reverse osmosis film device 3, one-level water tank 4, secondary water pump 5, two-pass reverse osmosis film device 6 and clear water tank 7; One-level water pump 2 connects between pre-treatment water tank 1 and the first-stage reverse osmosis film device 3, and the outlet of first-stage reverse osmosis film device 3 is communicated with one-level water tank 4; Secondary water pump 5 is connected between one-level water tank 4 and the two-pass reverse osmosis film device 6, and 6 outlets of two-pass reverse osmosis film device are communicated with clear water tank 7.
The two-pass reverse osmosis purified water equipment of the utility model; Trade effluent is at first passed through pre-treatment; Get into one-level RO system then and carry out initial gross separation; 99% heavy metal ion in the reduction water gets into secondary RO system once more and carries out degree of depth separation, makes water thoroughly reach the requirement of the purifying of medicinal and related industries.Solved traditional method adopt IX with the pollution of soda acid relief liquor, play a role in energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Nomenclature among the figure: pre-treatment water tank 1, one-level water pump 2, first-stage reverse osmosis film device 3, one-level water tank 4, secondary water pump 5, two-pass reverse osmosis film device 6, clear water tank 7.
Embodiment
As shown in Figure 1, two-pass reverse osmosis purified water equipment comprises the pre-treatment water tank 1 that is loaded with pretreated water; Also comprise one-level water pump 2, first-stage reverse osmosis film device 3, one-level water tank 4, secondary water pump 5, two-pass reverse osmosis film device 6 and clear water tank 7; One-level water pump 2 connects between pre-treatment water tank 1 and the first-stage reverse osmosis film device 3, and the outlet of first-stage reverse osmosis film device 3 is communicated with one-level water tank 4; Secondary water pump 5 is connected between one-level water tank 4 and the two-pass reverse osmosis film device 6, and 6 outlets of two-pass reverse osmosis film device are communicated with clear water tank 7.
First-stage reverse osmosis film device 3 is to be connected in parallel through branch line by 2-6 reverse osmosis filter to form with two-pass reverse osmosis film device 6.
The RO film is installed in the reverse osmosis filter.
Reverse osmosis membrane equipment, promptly RO film: RO is the abbreviation of English Reverse Osmosis membrane, the Chinese meaning is: reverse osmosis.The flow pattern of general water is to flow to high density by lower concentration, after the water pressurization in a single day, and will be by high concentration flow to lower concentration; That is so-called reverse osmosis principle: because the aperture of RO film is 5/1000000ths (0.0001 microns) of hairline; General naked eyes can't see that bacterium, virus are its 5000 times, therefore; Have only the mineral ion of water molecules and the useful human body of part to pass through, other impurity and heavy metal are discharged by waste pipe.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
