Industrial wastewater treatment device

Abstract

The invention relates to the technical field of wastewater treatment, and discloses an industrial wastewater treatment device which comprises a sedimentation tank, one side of the sedimentation tank is fixedly connected with a wastewater inlet, the other side of the sedimentation tank is fixedly connected with a wastewater outlet, an air dissolving pump is fixedly mounted below the wastewater outlet, and one end of the gas dissolving pump is fixedly connected with a gas dissolving nozzle and is positioned at the bottom of the sedimentation tank. Dissolved air generated by a dissolved air pump enters a sedimentation tank to enable suspended matter and oil water to rise, a motor drives a chassis to rotate to drive a double-tooth-direction chain belt to enable a cross rod to drive a slag scraping plate to rotate, the rising dissolved air is cut and reduced by a rotary knife, and the chassis drives a rotary arm to rotate to enable a swing rod to drive a sliding rod to move up and down in a sliding groove, so that the filter cloth is driven by the sliding rod to generate a wave shape, so that oil and water can float up more quickly, suspended matters are retained at the lower part and scraped into the slag accumulation groove by the slag scraping plate, and the problem that the suspended matters, the oil and water and the like float up together due to large dissolved air generated by the dissolved air pump and cannot be correspondingly treated is solved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial wastewater treatment device. Background technique [0002] The industrial wastewater treatment device is a kind of equipment for purifying and treating the wastewater generated by industrial production. Generally, industrial wastewater contains oil, suspended solids, heavy metals and other pollutants, and direct discharge will pollute the environment. Generally, the method of natural settlement makes the Heavy metals are precipitated, and dissolved air is injected to make oil float up, and different pollutants can be collected intensively by using different layers. [0003] There are still some problems in the existing industrial wastewater treatment devices: First, the dissolved air is generated by the dissolved air pump and injected into the sedimentation tank, but the dissolved air generated by the dissolved air pump and discharged through the pipeli...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing industrial wastewater treatment device proposed in the background technology, the present invention provides an industrial wastewater treatment device, which has the advantages of being able to completely collect pollutants in layers and completely separate oil and water, and solve the above problems.
