Abstract
The utility model discloses a zero-discharge concentration treatment system for explosion hook electroplating wastewater. The treatment system comprises a sedimentation tank, a first booster pump, a plate ultra-filtration system, a second booster pump, a 5mu cartridge filter, an RO (reverse osmosis) concentration system, an RO concentration water tank and an evaporator which are sequentially connected by a pipeline. The treatment system is simple in structure and low in cost, has fine treatment effects for the explosion hook electroplating wastewater, zero discharge of the electroplating wastewater can be realized, and salt can be recycled.
Description
Technical field
The utility model relates to a kind of fried hook electroplating wastewater zero concentrating and treating system.
Background technology
Plating is exactly to utilize electrolysis principle at metal or other plated surface last layer metal or alloy, to realize the raising of material property, such as 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, some electroplating wastewaters contain 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, such as Ni
2+, contain the negatively charged ion with coordination ability in some electroplating wastewaters, such as CN
-So the positively charged ion in these electroplating wastewaters often exists with the form of complex cation, such as Cd (CN)
-In addition, in electroplating wastewater, often also contain organic additive.
Contain more heavy metal ion in the fried hook electroplating wastewater, or the complexing ion of heavy metal, heavy metal ion drains in the environment, can enrichment in environment, it can enter by the mode of food chain in the human body, if the heavy metal ion of human body Excessive Intake may cause shock, ypotension, haemolysis, hepatitis, jaundice etc.
In the prior art, general, fried hook wastewater zero discharge concentration equipment is made of former pond → former water topping-up pump → disc filter → charcoal absorption system → Full-automatic ultra-filtering system → intermediate water tank → middle water pump → cartridge filter → Full-automatic reverse-osmosis system (containing washing unit) → water reservoir substantially, yet, its defective part is: the purpose that can't reach wastewater zero discharge, contain heavy metal ion and a large amount of recyclable salts in the reverse osmosis concentrated water, be difficult to realize wastewater zero discharge, the reuse water yield is limited, and the dense water yield is large; Treatment process is often too complicated, and cost is higher, often also can't reach the standard of zero release.
The utility model content
The purpose of this utility model provides a kind of fried hook electroplating wastewater zero concentrating and treating system.
Technical solution adopted in the utility model is:
A kind of fried hook electroplating wastewater zero concentrating and treating system, it comprises the concentrated water tank of settling tank, the first topping-up pump, chip ultrafiltration system, the second topping-up pump, 5 μ cartridge filters, RO concentration systems, RO, the vaporizer that connects successively by pipeline.
The filtering accuracy of described chip ultrafiltration system is less than 0.05 μ m.
The filtering accuracy of described chip ultrafiltration system is 0.045 μ m.
The beneficial effects of the utility model are: system of the present utility model consists of simple, for fried hook waste water preferably treatment effect is arranged, and can realize the zero release of electroplating wastewater.System of the present utility model consists of simple, and is with low cost, can reclaim salt simultaneously.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, fried hook electroplating wastewater zero concentrating and treating system of the present utility model, it comprises the concentrated water tank 8 of settling tank 1, the first topping-up pump 2, chip ultrafiltration system 3, the second topping-up pump 5,5 μ cartridge filters 6, RO concentration systems 7, RO, the vaporizer 9 that connects successively by pipeline.
Native system also comprises a PLC electrical control system 10, the whole control of its realization to whole system.
The fried hook waste water that settling tank 1 is collected through pre-treatment, in settling tank 1, the suspended substance of comparatively large vol is precipitated, the first topping-up pump 2 pumps into chip ultrafiltration system 3 with the supernatant liquor in the settling tank 1, ultra-filtration membrane in the chip ultrafiltration system 3 is the YJUF film, its filtering accuracy is 0.045 μ m, RO water inlet requirement can directly be satisfied in effluent quality SDI＜3, pump into 5 μ cartridge filters 6 by the second topping-up pump 5 again through the water behind the chip ultrafiltration system 3, the effect of 5 μ cartridge filters 6 is to hold back the particle greater than 5 μ m that former water brings, and enters reverse osmosis system to prevent it.Filter element in the cartridge filter 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.Cartridge filter adopts corrosion resistant 304 stainless steel shells, filter stick adopts 5 μ m flat-crushing type filter cores, continue to be pumped to 7 dehydrations of RO concentration systems through the water after 6 filtrations of 5 μ cartridge filters concentrated, dehydration rate is 60-70%, then continue to be pumped to the concentrated water tank 8 of RO through the dense water after concentrated, enter at last vaporizer 9 evaporations and reclaim salt.
In the native system, the technical indicator of RO concentration systems is:
Enrichment factor: 60-70%
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 are silted in water inlet up
After system of the present utility model processing, can realize the zero release of fried hook electroplating wastewater, remove the COD in the electroplating wastewater, reach relevant emission standard.
