Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further described.

Referring to Fig. 1, this nickel reclaims circulating device, water washing cylinder 5 and RO reverse osmosis membrane 7 is reclaimed including nickel, also include filtering tank 1, former water pot 4, pure water tank 9 and dense water pot 12, wherein, nickel reclaims the overflow outlet of water washing cylinder 5 and is connected with the import of former water pot 4, the outlet of former water pot 4 is connected by the import of input pipe 2 with filtering tank 1, the outlet of filtering tank 1 is connected by the import of outlet tube 20 with RO reverse osmosis membrane 7, first outlet of RO reverse osmosis membrane 7 goes out pipe 11 by dense water and is connected with the import of dense water pot 12, the outlet of dense water pot 12 is connected with nickel cylinder 14, second outlet of RO reverse osmosis membrane 7 goes out pipe 8 by pure water and is connected with the import of pure water tank 9, the outlet of pure water tank 9 is reclaimed water washing cylinder 5 with nickel and is connected.

In the present embodiment, described input pipe 2 is provided with raw water pump 3.

Described outlet tube 20 is provided with high-pressure pump 6.

The outlet of described pure water tank 9 is reclaimed water washing cylinder 5 by return pipe 19 with nickel and is connected；Return pipe 19 is provided with pure water rear pump 10.

It is provided with dense water rear pump 13 between outlet and the nickel cylinder 14 of described dense water pot 12.

The sand post filter, the filtration of carbon post, demineralizer and the accurate filter that are interconnected it is disposed with between import and the outlet of filtering tank 1 of described filtering tank 1.In other words, sand post filter, the filtration of carbon post, demineralizer and accurate filter it are integrated with in filtering tank 1.

Producing printed circuit board is three big heavy metal pollution industries; and heavy metal contaminants occurs mainly with electroplating work procedure; in order to carry out and implement the country such as " Law on Environmental Protection ", Water Pollution Prevention Law, " promotion law on cleaner production " and local environmental law Laws & Regulations file regulation; advocate energy-saving and emission-reduction, control to reduce the total emission volumn of pollutant nickel; the economic recovery improving nickel is worth, and applicant determines production nickel-containing waste water is carried out reuse recycling.

In the present embodiment, basic technological process is: the nickeliferous former water of workshop nickel-containing waste water or workshop former water pot raw water pump sand post filters carbon post and filters accurate filter high-pressure pump RO reverse osmosis membrane pure water tank supply workshop.

First, adopt sand filter, charcoal filter, demineralizer, accurate filter that former water carries out pretreatment, remove the salt in water, Organic substance and solid suspension etc.；Then being pumped into reverse osmosis membrane by high-pressure pump, make moisture two parts flow out under principle of reverse osmosis effect, a part of salinity height is called dense water, and a part of salinity is low to be called fresh water or produces water.Here salt is primarily referred to as heavy metal cation and anion.

Reverse osmosis membrane separation technology is the inverse process of infiltration, and its principle is that water is separated by with solution permeable membrane, the lateral solution infiltration of water, has osmotic pressure between biphase.If solution mutually on pressurize more than osmotic pressure, then solution mutually in water will to the infiltration of aqueous phase opposite direction in the past.Utilizing reverse osmosis to obtain desalted water, former water at a pressure sufficient, becomes pure water by permeable membrane, it does not have be gradually increased by the water dissolution thing concentration of suspension of film.
