Abstract
The utility model discloses an electroplating pretreatment wastewater treatment system which comprises an oil separation tank, an air floating sedimentation machine, a primary flocculation tank, a secondary flocculation tank, a sedimentation tank and a UF (ultrafiltration) membrane coagulation suction filter, wherein the oil separation tank, the air floating sedimentation machine, the primary flocculation tank, the secondary flocculation tank, the sedimentation tank and the UF membrane coagulation suction filter are sequentially connected; a first water pump is arranged between the oil separation tank and the air floating sedimentation machine; and a second water pump is arranged between the air floating sedimentation machine and the primary flocculation tank. The electroplating pretreatment wastewater treatment system disclosed by the utility model solves the technical problem that the system flow of an existing electroplating pretreatment wastewater chemical sedimentation method is relatively complicated, and has the advantages of simple system flow, good treatment effect and the like.
Description
Technical field
The utility model relates to a kind of Waste Water Treatment, particularly the pre-electroplating treatment Waste Water Treatment.
Background technology
Pre-electroplating treatment is that workpiece or material that needs are electroplated are electroplated front surface treatment, so that it meets the requirement of plating, improves by the deposition quality of metallizing at matrix surface.The ultimate aim of pre-electroplating treatment is to make the atoms metal that is plated matrix surface out exposed as much as possible, is accepted electronics just than being easier on matrix by the ion of metallizing like this.
General metal works all can exist greasy dirt or corrosion in the metal manufacturing processed, so general pre-treatment mode all comprises oil removing and rust cleaning process, acid cleaning process namely, said process can produce a large amount of pre-electroplating treatment waste water, contain particularly iron ion of a large amount of greases and heavy metal ion in such waste water, if directly discharging easily causes serious pollution to environment.Therefore to pass through strict processing, after indices reaches the regulation of National Environment Policy Act, could discharge.
Treatment process commonly used is chemical precipitation method at present, and it has the advantages such as investment is little, and working cost is low, is used widely at present.But the treatment scheme of existing pre-electroplating treatment waste water chemical precipitation method is more loaded down with trivial details, poor processing effect.
The utility model content
The purpose of this utility model is to provide a kind of total system simple in order to solve above-mentioned the deficiencies in the prior art, the pre-electroplating treatment Waste Water Treatment good to the treatment effect of pre-electroplating treatment waste water.
To achieve these goals, the pre-electroplating treatment Waste Water Treatment that the utility model is designed, comprise oil trap, air supporting precipitation machine, one-level flocculation tank, secondary flocculation tank, settling tank and UF film coagulation suction filter, described oil trap, air supporting precipitation machine, one-level flocculation tank, secondary flocculation tank, settling tank and UF film coagulation suction filter connect successively, be provided with the first water pump between the gentle floating precipitation machine of oil trap, be provided with the second water pump between air supporting precipitation machine and one-level flocculation tank.
The pre-treatment Waste Water Treatment that the utility model obtains, total system is simple, treatment effect to pre-electroplating treatment waste water is good, the gentle floating precipitation machine of oil trap successively acts on, with the grease filtering in pre-electroplating treatment waste water, the pre-electroplating treatment waste water that then contains a large amount of iron ions and a small amount of other metal ions condenses at flocculation tank under the chemical agent effect, then forms the alumen ustum throw out in settling tank, finally together gets rid of with mud.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
In figure: oil trap 1, the first water pump 2, air supporting precipitation machine 3, the second water pump 4, one-level flocculation tank 5, secondary flocculation tank 6, settling tank 7, UF film coagulation suction filter 8.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, the pre-electroplating treatment Waste Water Treatment that the present embodiment provides, comprise oil trap 1, air supporting precipitation machine 3, one-level flocculation tank 5, secondary flocculation tank 6, settling tank 7 and UF film coagulation suction filter 8, described oil trap 1, air supporting precipitation machine 3, one-level flocculation tank 5, secondary flocculation tank 6, settling tank 7 and UF film coagulation suction filter 8 connect successively, be provided with the first water pump 2 between the gentle floating precipitation machine 3 of oil trap 1, be provided with the second water pump 4 between air supporting precipitation machine 3 and one-level flocculation tank 5.
UF film in above-mentioned UF film coagulation suction filter 8 is current material, is those skilled in the art's common practise, therefore seldom be described in detail at this.
In concrete enforcement; the staff can add bodied ferric sulfate (PFS)/polyacrylamide (PAM) and alkali/acid usually in air supporting precipitation machine 3; add ion capturing agent in one-level flocculation tank 5, add Peroxyacetyl nitrate (PAN) simultaneously in secondary flocculation tank 6.Adding of above-mentioned auxiliary agent can guarantee that the present embodiment is to effective removal of grease and iron ion in pre-electroplating treatment waste water.
Claims (1)
1. pre-electroplating treatment Waste Water Treatment, comprise oil trap (1), air supporting precipitation machine (3), one-level flocculation tank (5), secondary flocculation tank (6), settling tank (7) and UF film coagulation suction filter (8), it is characterized in that: described oil trap (1), air supporting precipitation machine (3), one-level flocculation tank (5), secondary flocculation tank (6), settling tank (7) and UF film coagulation suction filter (8) connect successively, be provided with the first water pump (2) between the gentle floating precipitation machine of oil trap (1) (3), be provided with the second water pump (4) between air supporting precipitation machine (3) and one-level flocculation tank (5).
