Technical field
The utility model relates to water saving field, particularly relate to a kind of by the plating line circulating water saving system of nanofiltration processing.
Background technology
Electroplating industry not only can improve protection and the decorate properties of product, and for industrial and agricultural production provides a lot of novel materials, is an important industrial trade.But electroplating rinse water contains the pollutents such as heavy metal ion, poisonous negatively charged ion and complex compound, once be discharged in environment, can cause serious harm to water source and soil, threaten human health.On the other hand, because technique falls behind, equipment is simple, and material consumption, the water consumption of Chinese most of electroplating enterprises all substantially exceed external mean level (ML).
The matting of plating line, conventional is adverse current washing at present, refers to that workpiece motion s direction is contrary with water (flow) direction, the water inlet of final stage water washing cylinder, the water outlet of first step water washing cylinder, so first washes again with clean washing by addle, compare and technique in the past, both can lack water, can clean up again.But this method remains water inlet continuously, and draining endlessly, even if plating solution content is lower in first step water washing cylinder, also still drains, and has caused like this waste.In addition, clean at present water outlet and be often directly discharged to waste water station and process, return like this environmental protection and caused pressure.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, saves plating line water consumption, reduces wastewater treatment pressure and cost, and a kind of plating line circulating water saving system is provided.
For addressing the above problem, the utility model has adopted following technical proposals: a kind of plating line circulating water saving system, comprise plating tank, multi-stage countercurrent washing bath, Cleaning Wastewater receiving tank, pre-filtrating equipment, nanofiltration device, rinse water storage tanks, dosing temporary tank, it is characterized in that multi-stage countercurrent washing bath is near plating tank, the water-in of multi-stage countercurrent washing bath connects rinse water storage tanks, the water outlet of multi-stage countercurrent washing bath connects Cleaning Wastewater receiving tank, Cleaning Wastewater receiving tank connects pre-filtrating equipment, pre-filtrating equipment connects nanofiltration device, the water outlet of nanofiltration device connects to rinse water storage tanks, the dense water out of nanofiltration device connects to dosing temporary tank, dosing temporary tank connects plating tank.
In described Cleaning Wastewater receiving tank, be provided with pH monitoring setting device.
The Cleaning Wastewater of described multi-stage countercurrent washing bath first step washing bath is discharged into Cleaning Wastewater receiving tank by attached overflow groove.
Described pre-filtrating equipment is made up of sand filtration cylinder and carbon filtering jar, and sand filtration cylinder is before carbon filtering jar.
Described nanofiltration device comprises preposition accurate filter and a topping-up pump, first uses accurate filter impurity screening can prevent that nanofiltration module from stopping up, and improves filtration efficiency.
The concentrated stream of described nanofiltration device output enters described dosing temporary tank, and for electroplating the configuration of cylinder plating solution, the fresh water of output flows into described rinse water storage tanks, can be used for plating piece and the production link such as washes.
The utility model has the advantages that: make the plating piece of plating line clean more clean thorough, reduce rinse water consumption simultaneously, recycle rinse water, water-saving result is remarkable, has alleviated the pressure of wastewater treatment, reduces the wasting of resources amount of electroplating enterprise and alleviates the pollution of electroplating industry to environment, flow process is simple, invest littlely, process cost is low, has promoted the Sustainable development of electroplating industry.
