Embodiment 1

[0031] according to figure 1 , image 3 and Figure 4As shown, including the sedimentation tank 1, both sides of the top of the sedimentation tank 1 are provided with a first chute, and the first slider 2 is slidably connected in the two first chute, and the two first sliders 2 are slidably set respectively. On both sides of the bottom of the first slide plate 3, both sides of the top of the first slide plate 3 are fixedly provided with supporting blocks 4, one side of one of the supporting blocks 4 is fixedly provided with a first support bar 5, and the two sides of the first support bar 5 A plurality of stirring rods 6 are fixed on each side, and the stirring rods 6 mix and stir the decomplexing agent. The outer wall of the first support rod 5 is rotatably connected with a drum 7, and one side of the drum 7 is provided with a liquid inlet. The outer wall of 7 is provided with a plurality of liquid outlets. When the first slide plate 3 moves, the use of the second rack 22, ...

Embodiment 2

[0033] On the basis of embodiment one, according to figure 2 , Figure 5 and Image 6 As shown, the middle part of both sides of the inner wall of the sedimentation tank 1 is provided with a second chute, and a second slide block 10 is slidably connected in the two second chute, and the two second slide blocks 10 are fixedly arranged on the second slide plate respectively. On both sides of 11, the bottom end of the second slide plate 11 is provided with a through groove, and the first air bag 12 is fixed in the through groove, and the bottom end of the first air bag 12 is fixed with a scraper 13, and the scraper 13 is interspersed with the through groove. , the bottom ends of the two second sliders 10 are fixedly provided with a pressure plate 14, and the bottom ends of the two pressure plates 14 are fitted with a second air bag 15. During the movement of the second slider 10, the second slider 10 and the friction bar 17, the gas in the second airbag 15 is heated, and at th...

Embodiment 3

[0035] On the basis of embodiment one and embodiment two, according to Figure 1-6 As shown, the rotating drum 7 and the stirring shaft 9 rotate synchronously to realize mixing and stirring of the decomplexing agent and waste water while spraying the decomplexing agent evenly to make them evenly mixed, and then place it in the sedimentation tank 1 for further The sediment is left standing, and during the movement of the second slider 10, through the frictional contact with the friction bar 17, and then through the action of the pressure plate 14, the second air bag 15, the exhaust pipe and the nozzle 16, the water is passed into the sedimentation tank 1. The hot steam dries the sludge settled in the sedimentation tank 1. At the same time, during the continuous friction between the second slider 10 and the friction bar 17, the first air bag 12 expands, driving the scraper 13 to move downward, and the sediment The sludge in the pool 1 is scraped and cleaned, and as the first air...

Abstract

The invention discloses a nickel surface treatment wastewater treatment system and method. The system comprises a sedimentation tank, first sliding grooves are formed in the two sides of the top end of the sedimentation tank correspondingly, first sliding blocks are slidably connected in the two first sliding grooves correspondingly, the two first sliding blocks are slidably arranged on the two sides of the bottom end of a first sliding plate correspondingly, and supporting blocks are fixedly arranged on the two sides of the top end of the first sliding plate correspondingly, wherein one side of one supporting block is fixedly provided with a first supporting rod, and the two sides of the first supporting rod are each fixedly provided with a plurality of stirring rods. According to the nickel surface treatment wastewater treatment system and method, through the arrangement of the rotating cylinder and the stirring shaft, in the movement process of the first sliding plate, through the meshing effect of the second rack and the second gear, the rotating drum is driven to rotate under the transmission action of the first bevel gear and the second bevel gear, and the complexing breaking agent in the rotating drum is uniformly sprayed into the sedimentation tank through the liquid outlet, so that the complexing breaking agent is uniformly distributed in the wastewater in the sedimentation tank, and the complexing breaking agent and the wastewater can uniformly and fully react conveniently.

Description

technical field [0001] The invention relates to wastewater treatment, in particular to a nickel surface treatment wastewater treatment system and method. Background technique [0002] Electroplating is to deposit the required coating on the surface of the product by electrochemical method, so as to realize the protection and modification of the metal or non-metal surface, and to obtain new performance of the product. In recent years, my country's electroplating industry has developed rapidly. As the main method of metal surface modification, nickel plating will produce a large amount of nickel-containing wastewater. According to incomplete statistics, 4 billion m3 of electroplating wastewater is discharged every year, of which 50% have not reached Discharge standards, the pollutants of electroplating wastewater are difficult to biodegrade, easy to accumulate in organisms, and discharged into the environment will pose a serious threat to the environment and humans. [0003] I...
