Description
Technical field
The utility model relates to the tail washings treatment unit of a kind of waste water reclamation device, particularly a kind of etching waste water reclamation.
Background technology
Board production technology move back the tin operation, be to adopt the mixing solutions of nitric acid and nitrate that anti-etching tin coating is dissolved, this mixing solutions is commonly called as tin stripper.When the concentration of tin reached the 60-80 grams per liter in being dissolved in tin-stripping solution, tin-stripping solution is the very difficult tin coating that continues again on the leach circuit plate.The tin that is dissolved in the tin stripper exists with the metastannic acid form, is colloidal, can stably be suspended in Xi Shuizhong, deposits generally speaking all can not precipitate in 3-6 month.For reclaiming metastannic acid in the tin stripper, existing method is to transfer pH value to 7-8 with a large amount of ammoniacal liquor, add the Tai-Ace S 150 precipitation agent then, making Tai-Ace S 150 is to produce alumine hydroxide colloid under the condition of 7-8 at pH value, metastannic acid risen stick the bridge formation adsorption, thereby the metastannic acid particle is strengthened and form throw out.
Circuit board copper facet etch mechanism: Cu+CuCl2 → Cu2Cl2
Cu2Cl2+4Cl-→2(CuCl3)2-
2) influence the factor of etch-rate: the principal element that influences etch-rate is the content of Cl-in the solution, Cu+, Cu2+ and the temperature of etching solution etc.
Alkaline copper chloride etching solution
1) etching mechanism: CuCl2+4NH3 → Cu (NH3) 4Cl2
Cu(NH3)4Cl2+Cu→2Cu(NH3)2Cl
2) influence the factor of etch-rate: the temperature of the Cu2+ concentration in the etching solution, pH value, ammonium chloride concentration and etching solution is all influential to etch-rate.
Recovery method to tin-stripping wastewater is the pH value of adjusting tin-stripping wastewater, allows tin element produce water-fast throw out, forms the tindioxide powder through press filtration, washing, oven dry then.
For the recovery of the copper in the etching waste water, be to distinguish according to the technology of etching solution, select reclaim(ed) sulfuric acid copper or basic copper chloride.
Above-mentioned waste water is through the tail washings after reclaiming, and existing enterprise can't utilize, and discharges after can only reducing its toxicity by the mode of chemistry.
Shortcoming/the deficiency of prior art:
Prior art in reclaiming this class waste water tin element and with element after can't utilize tail washings.Remaining a large amount of tail washings is unprocessed just directly discharging often, causes the wasting of resources and environmental pollution.
The utility model content
Technical problem to be solved in the utility model is that at present institute's wastewater recycling process that uses can't take full advantage of the residue tail washings, and is often unprocessed with regard to directly discharging, and causes the wasting of resources and environmental pollution.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Reclaim the technical disadvantages that technology exists at existing etching waste water and tin-stripping wastewater, redesign a kind of tail washings treatment unit of etching waste water reclamation, comprise the copper sludge storing unit, the dense washing lotion storing unit of copper, tin workshop waste water hold-up vessel, tin workshop sewage pretreatment device, the first press filtration groove, first ion exchange system, the waste water storing unit, copper workshop waste water hold-up vessel, copper workshop sewage pretreatment device, second filter-pressing device, second ion exchange system, triple-effect evaporator, the crystallisation by cooling machine, the suction filtration device, centrifuge, the mother liquor hold-up vessel, the phlegma hold-up vessel, the 3rd ion exchange system, neutralising arrangement, the alkali lye hold-up vessel, water store tank up to standard; Described tin workshop waste water hold-up vessel, tin workshop sewage pretreatment device, the first press filtration groove, first ion exchange system are connected successively with the waste water storing unit; Described copper workshop sewage pretreatment device, second filter-pressing device, second ion exchange system, triple-effect evaporator, crystallisation by cooling machine, suction filtration device are connected successively with centrifuge, and the suction filtration device is connected with triple-effect evaporator by the mother liquor hold-up vessel with centrifuge; The first press filtration groove, second filter-pressing device are connected with the copper sludge storing unit respectively, and first ion exchange system is connected with the dense washing lotion storing unit of copper respectively with second ion exchange system; Phlegma hold-up vessel, the 3rd ion exchange system, neutralising arrangement and water store tank up to standard are connected successively, and the alkali lye hold-up vessel is connected with neutralising arrangement, and the phlegma hold-up vessel is connected with triple-effect evaporator.
The utlity model has that technical process is simple, technical process is short, can reach the advantage of nontoxic discharging.
