Industrial wastewater treatment device

Abstract

The invention discloses an industrial waste water treatment device, which comprises a bracket, a decontamination device and an aeration tank. The decontamination device includes a water treatment tank, a mud scraping assembly, a filter plate and a neutralizer filter layer. One end of the water treatment tank is provided with a collection tank, and the filter plate and the neutralizer filter layer are sequentially arranged from top to bottom. Fixed inside the water treatment tank, the mud scraper assembly is composed of a mounting plate, a push rod motor, a fixed plate, a first connecting rod, a first mud scraper, a second connecting rod, and a second mud scraper. A first through hole and a second through hole are respectively provided at the positions corresponding to the side wall of the treatment tank body, the filter screen plate and the collecting tank. The output end of the rod motor is connected with the fixed plate. This kind of industrial wastewater treatment device has good sludge filtering effect, low cost and reasonable structure.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater treatment device. Background technique [0002] Now the water pollution problem in China and even the world is becoming more and more serious. Therefore, it is very important and necessary to do a good job in the recycling of water resources. The well-known industrial wastewater treatment equipment is composed of two stages of sedimentation and filtration. The filter device uses filter cotton , filter yarn and other filter materials not only have high cost and complex structure, but also the sludge sedimentation is not easy to remove. Usually, the desilting process needs to be done manually, which takes a long time, is labor-intensive, and the desilting cost is high. [0003] For example, the Chinese invention patent of CN 203999210 U discloses a wastewater treatment device, including a first treatment tank, a second treatment tank...

[0002] Now the water pollution problem in China and even the world is becoming more and more serious. Therefore, it is very important and necessary to do a good job in the recycling of water resources. The well-known industrial wastewater treatment equipment is composed of two stages of sedimentation and filtration. The filter device uses filter cotton , filter yarn and other filter materials, not only the cost is high, the structure is complex, and the sludge sediment is not easy to remove, usually the desilting process needs to be done manually, which takes a long time, labor-intensive, and the desilting cost is high

[0003] For example, the Chinese invention patent of CN 203999210 U discloses a wastewater treatment device, including a first treatment tank, a second treatment tank, a first dissolved gas tank, a second dissolved gas tank, and a pretreatment tank. The pool is provided with a waste water inlet, the pretreatment pool is connected with the first treatment pool through the outlet pipe, the first treatment pool is connected with the second treatment pool through the water pipe, the first dissolved gas tank is connected with the first treatment pool through the first air pipe, and the second The second gas-dissolving tank communicates with the second treatment tank through the second air pipe, the outlet of the first air pipe is arranged below the outlet of the water outlet pipe, the outlet of the second air pipe is arranged below the outlet of the water passing pipe, and the first treatment The bottom surface of the tank is funnel-shaped, and a slag discharge pipe is provided in the middle of the bottom surface, and an emptying pipe is provided in the middle of the bottom surface of the second treatment tank, which can adapt to the treatment of sewage with different concentrations, but its structure is relatively complicated, the cost is high, and Desilting effect is not ideal

[0004] For example, the patent No. CN 203269693 U provides a circulating water treatment system, including a circulating pool, a treatment tower, a treatment pool and a clean water pool. The upper part of the treatment tower is provided with a water outlet, and the lower part is provided with a water inlet. The lower part is provided with a water inlet, and the circulating pool is connected to the water inlet of the treatment tower, and the outlet of the treatment tower is connected to the water inlet of the treatment tank. Although it has good filtering and sterilizing effects, it has a poor effect on removing sediment in the water
