Description

Printed circuit board heavy metal wastewater thereby copper retrieving arrangement
Technical field
The utility model relates to a kind of printed circuit board heavy metal wastewater thereby copper retrieving arrangement, belongs to waste liquid metal recovery field.
Background technology
Current environmental requirement is increasingly serious, and printed circuit board belongs to polluted enterprises, requires to face a severe test especially to government's Compulsory Feature energy-saving and emission-reduction; The printed circuit board plating department cupric ion produced in metallic wastewater is difficult to process in Sewage treatment systems; Equipment exhausting heavy metal containing sewage Cu 2+concentration is 80 ~ 120g/L, environmental protection station processed waste water discharge Cu 2+concentration≤3mg/L, careless slightly exceeding standard just faces the hidden danger of suspending operations for consolidation.The method of current recovery heavy metal ions in wastewater mainly contains coagulant sedimentation and electrolytic process, and the two respectively has quality, and coagulant sedimentation speed is fast, and efficiency is high, but reclaims not thorough, and the electrolytic process rate of recovery is high, but time concentration of metal ions is low, but efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of printed circuit board heavy metal wastewater thereby copper retrieving arrangement, the advantage of comprehensive coagulant sedimentation and electrolytic process, reclaims the Cu in heavy metal wastewater thereby fast up hill and dale 2+be discharged to sewage plant process again, extenuate the pressure of sewage plant, make its processed waste water emission standard up to standard.
The utility model is realized by following technical proposals.Printed circuit board heavy metal wastewater thereby copper retrieving arrangement comprises AC power, rectifier, anode, negative electrode, reaction cylinder, steel wire filtering net, permanent magnet, devil liquor recovery cylinder, recycle pump, AC power connects rectifier, rectifier connects the anode and negative electrode that are arranged in reaction cylinder, negative electrode is the steel plate be erected in reaction cylinder, steel wire filtering net is installed in reaction cylinder bottom, steel wire filtering net places permanent magnet, install bottom reaction cylinder and lead to the rising pipe of devil liquor recovery cylinder, the waste liquid of devil liquor recovery cylinder is circulated by recycle pump and pipeline and reaction cylinder.
Also at reaction cylinder, coagulant dosage pipe can be installed.
Also Vltrasonic device is set in reaction cylinder, ultrasonicly during electrolysis improves electrolytic efficiency, the ultrasonic effect also can playing cleaning steel wire filtering net.
The heavy metal wastewater thereby that production unit discharges first reclaims by the utility model, and coagulation enrichment improves copper ion concentration, then by direct current electromagnetic adsorption principle, the polluted by copper in waste liquid on steel plate; Metal waste liquid is by being discharged into sewage works again after electromagnetic adsorption; Greatly alleviate sewage plant processing pressure, make its sewage discharge up to standard.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, printed circuit board heavy metal wastewater thereby copper retrieving arrangement of the present utility model comprises AC power 1, rectifier 2, anode 3, negative electrode 4, reaction cylinder 5, steel wire filtering net 6, permanent magnet 7, Vltrasonic device 8, devil liquor recovery cylinder 9, recycle pump 10, AC power 1 connects rectifier 2, rectifier 2 connects the anode 3 and negative electrode 4 that are arranged in reaction cylinder 5, negative electrode 4 is for being erected at the steel plate in reaction cylinder 5, replaceable, steel wire filtering net 6 is installed in reaction cylinder 5 bottom, steel wire filtering net 6 is placed permanent magnet 7, thus make steel wire filtering net 6 carrying magnetic, also Vltrasonic device 8 is set in reaction cylinder 5, ultrasonicly during electrolysis improve electrolytic efficiency, the ultrasonic effect also can playing cleaning steel wire filtering net 6, the rising pipe leading to devil liquor recovery cylinder 9 is installed bottom reaction cylinder 5, the waste liquid of devil liquor recovery cylinder 9 is circulated by recycle pump 10 and pipeline and reaction cylinder 5.Also at reaction cylinder 5, coagulant dosage pipe can be installed.
First, Vltrasonic device 8 and rectifier 2 do not work, circulate between reaction cylinder 5 and devil liquor recovery cylinder 9 toward heavy metal wastewater thereby, dosing coagulant in reaction cylinder 5, coagulating agent is caught cupric ion and is deposited on steel wire filtering net 6, steel wire filtering net 6 carrying magnetic can improve its adsorption effect, after the cupric ion in reaction cylinder 5 reaches finite concentration, opens rectifier 2 and alternating-current is converted to direct current; Cross direct current electromagnetic adsorption principle, nonmetal in waste liquid is adsorbed on steel plate; Metal waste liquid is by being discharged into sewage works again after electromagnetic adsorption.
The above only have expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion, improvement and substitute, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
