Problems solved by technology

[0003] However, the existing sedimentation treatment has the following disadvantages: (1) usually the sewage is directly introduced from the reaction tank, then the sewage is allowed to stand still, and a flocculant is added. After the particles settle, the settled sewage is drawn out. Some sewage treatment devices have poor flocculation effect and long flocculation time, which is not conducive to the rapid treatment of sewage; (2) the existing sewage treatment devices have poor filtration and purification effect on water bodies; sometimes in order to improve sewage treatment efficiency, in the process of At the same time as flocculation, the water body will flow into the sedimentation tank under the action of gravity, which will cause the electroplating sewage to flow into the sedimentation tank after it cannot fully fuse with the flocculant, resulting in more suspended impurities in the sewage, which is not conducive to the complete precipitation of impurities

Settling tank 4, and the bottom of the settling tank 4 is conical funnel-shaped; the other side of the top surface of the base 1 is fixedly installed with a clean water tank 5, and a motor box is fixedly installed in the middle of the top surface of the flocculation tank 3 6. A first motor 7 is vertically fixedly installed in the motor box 6, and the model of the first motor...

Embodiment 2

[0040] Embodiment 2: In order to realize the disturbance of the water body in the sedimentation tank, in the present invention, the disturbance assembly includes a third casing 22, a stirring blade 23, a connecting rod 24 and a disturbance plate 25, and the third casing 22 is fixedly sleeved At the bottom end of the rotating rod 10, horizontally arranged stirring blades 23 are fixedly installed on both sides of the pipe body of the third sleeve 22, and a vertically arranged connecting rod is fixedly installed at the bottom end of the rotating rod 10. 24, the bottom end of the connecting rod 24 is fixedly installed with a horizontal disturbance plate 25, and a number of circular spoiler holes are equidistantly opened on the front end face of the disturbance plate 25; between the flocculation box 3 and The bottom between the sedimentation tanks 4 is horizontally provided with a first connecting pipe 26, and the two ends of the first connecting pipe 26 penetrate into the flocculat...

Embodiment 3

[0041] Embodiment 3: for better realizing the actual use of the present invention, refer to Figure 5 , In this embodiment, a method for operating a purification device for electroplating sewage filtration treatment is provided, specifically, including the following steps:

[0042] Step 1: Firstly, the first motor 7 and the second motor 9 are respectively electrically connected to the external power supply through wires, and then the sewage generated by electroplating is injected into the flocculation tank 3 from the water inlet pipe, and then the flocculant is put into the flocculation tank 3 from the dosing pipe. Inside the flocculation box 3;

[0043] Step 2, by controlling the rotation of the first motor 7 to drive the rotation of the rotation rod 10, the rotation of the rotation rod 10 drives the stirring assembly and the disturbance assembly to rotate, and the stirring assembly facilitates the fusion of the electroplating sewage and the flocculant to facilitate the unifo...

Abstract

The invention discloses a purification device for electroplating sewage filtration treatment and an operation method of the purification device. The purification device comprises a base, wherein a flocculation tank is fixed to the top surface of the base, and a settling tank is fixed into a rectangular opening of the base; a water purification tank is fixed to the other side of the top surface ofthe base, and a stirring assembly is fixedly mounted in the middle of the rotating rod; a disturbance assembly is fixedly mounted at the bottom of the rotating rod; a cylinder is fixedly mounted on one side in the settling tank; a conveying assembly is fixed in the cylinder; a filtering assembly is fixedly mounted on the other side of the settling tank; and a water purification assembly is fixedlymounted in the water purification tank. According to the invention, the problems of poor flocculation effect and long flocculation time in the existing electroplating sewage treatment process are solved through the stirring assembly; and the problem of sufficient fusion of existing electroplating sewage is solved through the conveying assembly.

Description

technical field [0001] The invention relates to the technical field of electroplating sewage treatment, in particular to a purification device for filtering and treating electroplating sewage and an operating method thereof. Background technique [0002] The metal ions in the sewage and waste liquid discharged from the electroplating factory are more harmful. If the untreated electroplating sewage is discharged into rivers, ponds or deep underground, it will not only endanger the environment, but also pollute drinking water and industrial water. The contained hexavalent chromium will pollute the environment and seriously endanger human health, so it must be treated carefully; sewage sedimentation is usually carried out in sedimentation tanks. [0003] However, the existing sedimentation treatment has the following disadvantages: (1) usually the sewage is directly introduced from the reaction tank, then the sewage is allowed to stand still, and a flocculant is added. After th...
