Description
Technical field
The utility model relates to a kind of sour copper electroplating wastewater zero concentrating and treating system.
Background technology
Plating is exactly to utilize electrolysis principle to plate layer of metal or alloy at metal or other surfaces, to realize the raising of material property, like the lifting of corrosion resistance nature.
Electroplating wastewater is to electroplate the waste water that factory discharges, and because of the difference of production technique, the electroplating wastewater that has contains chromium, and what have then contains cadmium, contains acid, contains alkali etc., and what the heavy metal ion in the electroplating wastewater had exists with simple cationic form, like Ni
2+, contain negatively charged ion in the electroplating wastewater that has, like CN with coordination ability
-So the positively charged ion in these electroplating wastewaters often exists with the form of complex cation, like Cd (CN)
-In addition, in electroplating wastewater, often also contain organic additive.
Usually contain deleterious cupric ion in the acid copper electroplating wastewater, if be discharged in the environment, will enrichment in environment; And possibly get into human body through the mode of food chain; Because cupric ion is a heavy metal elements, though in the metabolic processes of human body, play important effect, if excessive absorption; Possibly cause it in the human liver, to accumulate, cause poisoning.
Existing treatment process to sour copper electroplating wastewater; Generally be: former pond → former water topping-up pump → disc filter → activated carbon adsorption system → full-automatic ultrafiltration system → intermediate water tank → middle water pump → security personnel's strainer → full-automatic reverse osmosis system (containing washing unit) → water reservoir; The shortcoming that exists in the prior art is: reverse osmosis concentrated water discharges, and can't reach the purpose of wastewater zero discharge; Contain various heavy metal ion and a large amount of recyclable salts in the reverse osmosis concentrated water; Complex process, floor space is big, cost of investment is high.
The utility model content
The purpose of the utility model provides a kind of sour copper electroplating wastewater zero concentrating and treating system.
The technical scheme that the utility model is taked is:
A kind of sour copper electroplating wastewater zero concentrating and treating system, it comprises that the acid copper waste water water collecting basin that connects successively through pipeline, concentrated pond, recycle pump, TMF filtration unit, cleaned water tank, 5 μ security personnel strainer, RO concentration systems, RO concentrate water tank, vaporizer; Said TMF filtration unit returns through another pipeline and links concentrated pond; Also comprise the first pH regulator device, the second pH regulator device.
The said first pH regulator device is communicated on acid copper waste water water collecting basin and the pipeline that concentrated pond links to each other.
The said second pH regulator device is connected on the said cleaned water tank.
Said concentrated pond also is connected to pressure filter through pipeline.
The beneficial effect of the utility model is: the system of the utility model constitutes simple, to sour copper electroplating wastewater treatment effect is preferably arranged, and can realize the zero release of electroplating wastewater.The system of the utility model constitutes simple, and is with low cost, can reclaim salt simultaneously.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
As shown in Figure 1; The sour copper electroplating wastewater zero concentrating and treating system of the utility model, it comprises that the acid copper waste water water collecting basin 1 that connects successively through pipeline, concentrated pond 2, recycle pump 3, TMF filtration unit 4, cleaned water tank 5,5 μ security personnel strainer 6, RO concentration systems 7, RO concentrate water tank 8, vaporizer 9; Said TMF filtration unit 4 returns to link through another pipeline and concentrates pond 2; Also comprise the first pH regulator device 10, the second pH regulator device 11.
The said first pH regulator device 10 is communicated on acid copper waste water water collecting basin 1 and the pipeline that concentrated pond 2 links to each other.
The said second pH regulator device 11 is connected on the said cleaned water tank 5.
Said concentrated pond 2 also is connected to pressure filter 13 through pipeline.
Native system also comprises a PLC electrical control system 12, the whole control of its realization to total system.
The acid copper waste water that acid copper waste water water collecting basin 1 is collected through pre-treatment; Through the first pH regulator device 10 wastewater pH is adjusted to alkalescence (pH9-12); In water collecting basin; The suspended substance of comparatively large vol is able to deposition, concentrates pond 2 and then can precipitate the mud in TMF filtration unit 4 waste water that reflux and that water collecting basin enters, and mud is sent into and carried out solid-liquid separation in the pressure filter 13; Supernatant in the concentrated pond 2 is recycled pump 3 and pumps into TMF filtration unit 4; Water after the partial impurities that process TMF filtration unit 4 filters out in the water then gets into cleaned water tank 5 storages and regulates pH to neutrality through the second pH regulator device 11; Water in the cleaned water tank 5 then pumps into 5 μ security personnel strainer 6 by the suction topping-up pump; The effect of 5 μ security personnel strainer is to hold back the particle greater than 5 μ m that former water brings, and gets into reverse osmosis system to prevent it.Filter unit in security personnel's strainer is replaceable import filter core, and the absolute precision of this filter core is 5 μ m, adopts the unique seal mode, can not be short-circuited or leak, and be easy to change.Security personnel's strainer adopts corrosion resistant 304 stainless steel shells; Filter stick adopts 5 μ m flat-crushing type filter cores; Continuing to send into 7 dehydrations of RO concentration systems by HPP through the water after 6 filtrations of 5 μ security personnel strainer concentrates; Dehydration rate is 60-70%, gets into RO through the water after concentrating and concentrates water tank 8, gets into vaporizer 9 evaporations at last and reclaims salt.
In the native system, the technical indicator of RO concentration systems is:
Membranous type: press mold in 8 cun high density antipollutions
Brand: LG-DOW FILMTEC
TM
Pressurized vessel: 300psi
Material: glass reinforced plastic
The place of production: Jiangsu
Maximum operating temperature: 45 ℃
Water inlet chlorine residue: < 0.1PPM
Index: SDI < 5 is silted in water inlet up
Through after the system handles of the utility model, can realize the zero release of sour copper electroplating wastewater, remove the COD in the electroplating wastewater, reach relevant emission standard.
