[background technology]
Electroplating industry is the important processing industry of China, its product is widely used in the industry-by-industry, electroplating industry also is one of current China three large contaminated industries simultaneously, produces a large amount of waste water that contains the heavy metals such as cyanogen, chromium in its production process and brings serious pollution to environment.To this, although various places government has strengthened the dynamics of processing electroplating wastewater, but still can't take a large amount of medium and small electroplating enterprises into account, the electroplating wastewater processing cost of great number is so that exceed standard and steal row and omit the phenomenon of electroplating wastewater in printing along with the develop rapidly of electroplating industry is day by day serious, electroplating wastewater also increasingly sharpens to the pollution of environment, and the processing cost that therefore reduces electroplating wastewater can effectively solve the problem of electroplating wastewater contaminate environment.The utility model provides a kind of working cost low, effective for the problems referred to above, and processing and the reclamation set of the electroplating wastewater of energy recycling electroplating waste water.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, provides a kind of working cost low, effective, and processing and the reclamation set of the electroplating wastewater of energy recycling electroplating waste water.
For achieving the above object, the utility model adopts following technical proposal:
The processing of electroplating wastewater and reclamation set, include the comprehensive water collecting basin 3 that is used for collecting waste water that is connected on successively on the pipeline, can remove the polynary matchmaker of the pulse of metal ion pond 4 in the waste water, the reaction settling basin 7 that can purify water and reverse osmosis unit 8, be connected with the influent waste water passage 1 that waste water is imported comprehensive water collecting basin 3 at described comprehensive water collecting basin 3, described influent waste water passage 1 includes cyanide wastewater passage 12, contain chromium complexing waste water tunnel 14 and comprehensive wastewater passage 13, be serially connected with the broken cyanide device 21 that to remove the Cyanide in Waste Water compound at described cyanide wastewater passage 12, be serially connected with the contact break device 22 that to remove complex compound in the waste water at the described chromium complexing waste water tunnel 14 that contains.
Also be provided with pulse water distributing device 6 in the described polynary matchmaker pond 4.
Described reverse osmosis unit 8 includes cartridge filter, high-pressure pump, reverse osmosis membrane spare, monitoring instrument, PLC controller.
The beneficial effects of the utility model are: the utility model is respectively equipped with broken cyanide device, contact break device, the polynary matchmaker of pulse pond, reaction settling basin, reverse osmosis unit.With these several unit comprehensive utilizations, make it to consist of processing and the reclamation set of electroplating wastewater, can effectively reduce the processing cost of electroplating wastewater, after the processing and reclamation set processing of electroplating wastewater through electroplating wastewater, the indexs such as its heavy metal ion, turbidity and specific conductivity all can reach the source quality index of purifying waste water, but reuse reduces enterprise's water withdrawal as enterprise's water of productive use, and reclamation rate can reach 50%-80%.
[description of drawings]
Fig. 1 is schematic diagram of the present utility model.
[embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in Figure 1, the processing of electroplating wastewater and reclamation set, include: be connected on successively the comprehensive water collecting basin 3 that is used for collecting waste water on the pipeline, can remove the polynary matchmaker of the pulse of metal ion pond 4 in the waste water, the reaction settling basin 7 that can purify water and reverse osmosis unit 8, be connected with the influent waste water passage 1 that waste water is imported comprehensive water collecting basin 3 at described comprehensive water collecting basin 3, described influent waste water passage 1 includes cyanide wastewater passage 12, contain chromium complexing waste water tunnel 14 and comprehensive wastewater passage 13, in the described comprehensive wastewater passage 13 by not containing the waste water of cyanogen and chromium complex, be serially connected with the broken cyanide device 21 that to remove the Cyanide in Waste Water compound at described cyanide wastewater passage 12, the medicament that adds into described broken cyanide device 21 is clorox and sodium hydroxide, carries out broken cyanide by pH instrument and the dosing of metering the automatic control of pump in the process; Be serially connected with the contact break device 22 that can remove complex compound in the waste water at the described chromium complexing waste water tunnel 14 that contains, the medicament that adds into described contact break device 22 is the contact break agent, carries out contact break by ORP instrument and the dosing of metering the automatic control of pump in the process.
Be provided with polynary compounded mix 5 and pulse water distributing device 6 in the polynary matchmaker of the described pulse pond 4.
Described polynary compounded mix 5 is the filler through overactivation of iron filings and grain active carbon and cinder mixing, and it has the several functions such as oxidation, reduction, absorption and little electrolysis, in order to metal ions such as the chromium in the purifying electric waste electroplating, copper, zinc and nickel.Waste water through described pulse water distributing device 6 has pulse action to polynary compounded mix 5, makes polynary compounded mix 5 be difficult for block system, can improve Systems balanth and rate of utilization, reduces the backwash power consumption of filler.
Thereby the suspended impurity that described reaction settling basin 7 is made a return journey in dewatering by the neutralization flocculation purifies water.In and the flocculation sediment process: electroplating wastewater is regulated pH value through sodium hydroxide, polymerize aluminum chloride and polyacrylamide acting in conjunction, the formation precipitation of hydroxide, through cohesion or throwing out, granular mass increases, the rapid sedimentation of throw out, waste water is purified, and is conducive to reuse of wastewater.
