Etched foil surface is cleaned.In addition etched foil surface is cleaned other than removing surface acid solution and sundries, etched foil
Cl remained on surface-Content will be lower than 4ppm, therefore just need that a large amount of water is continuously added in rinse bath.And for corrosion
The present relative maturity of taking back and process technology of acid pickle, but contained substance is complicated in ejected wash water and content is lower, spent acid
Reuse technology can not be handled it, if direct emission can cause environmental pollution, it is therefore necessary to take measures to corrosion
Foil cleaning waste water is handled.
After mainly the waste water in rinse bath is mixed with other ejected wash waters to the processing method of ejected wash water at present at concentration
Reason, is mainly handled using chemical precipitation method, bioanalysis, and it is that waste water is in that chemical precipitation method processing, which needs to be added a large amount of alkali,
Then the species precipitate of indissoluble inside waste water is come out, is being filtered to remove by alkalinity.Chemical precipitation method not only increases production
Cost.Biochemical method not only takes up a large area, but also disposably puts into also bigger.Treated although water reaches for these methods
To discharge standard but can not reuse, and a kind of waste to resource.In order to reduce the waste to water resource and reduce total
The processing pressure of waste water needs to develop a kind of process for reclaiming of etched foil cleaning waste water.
Utility model content
Technical problem: in order to solve the defects of prior art, the utility model provides a kind of etched foil cleaning waste water
Reclaiming system.
Technical solution: a kind of reclaiming system of etched foil cleaning waste water provided by the utility model, including it is sequentially connected
Raw wastewater case, elevator pump 1, sand filter, intermediate water storage case, high-pressure pump, ultraviolet sterilizer and first group of RO；
