Description

technical field [0001] The invention belongs to the field of paint wastewater treatment, and in particular relates to a treatment device for industrial paint waste water, more specifically a treatment device and a treatment method for industrial paint waste water. Background technique [0002] In the current industrial field, a large amount of industrial paint wastewater containing solid particle impurities and oil suspended matter is often produced. If the industrial wastewater with oil pollution is discharged into the water body, the oil pollution will cover the water surface and prevent the oxygen in the air from dissolving into the water. Low oxygen content will hinder the photosynthesis of aquatic plants and cause the death of aquatic animals due to lack of oxygen. Oily wastewater enters the soil, hinders the reproduction of microorganisms in the soil, and destroys the aggregate structure of the soil layer. Industrial paint wastewater also contains a large amount of heav...

Problems solved by technology

[0003] In order to overcome the problems existing in the background technology, in the present invention, the operation of the second motor will drive the filter device to operate, and the operation of the filter device will drive a plurality of filter plates to rotate. At this time, industrial paint wastewater will pass through the inside of the filter plate and prevent reverse The holes flow from different spaces in the wastewater treatment barrel to each other, and then play a purification effect; at the same time, the industrial paint wastewater passes through the four filter plates of the sand filter plate, activated carbon filter plate, quartz sand filter plate, and oil-absorbing cotton filter plate in sequence. The rotation of the sand filter plate drives the rotation of the activated carbon filter plate, quartz sand filter plate, and oil-absorbing cotton filter plate, which further accelerates the treatment of industrial paint wastewater; as the waste water treatment tank starts to run, the waste water treatment tank should be covered at this time The upper bung, then turn on the ultraviolet sterilizing lamp for disinfection, and the second motor drives the sand filter plates, activated carbon filter plates, quartz sand filter plates, and oil-absorbing cotton filter plates in the multiple filter plates of the filter device to rotate for a period of time. Turn on the power and turn on the switch of the second water outlet of the industrial wastewater treatment device. The second water outlet is set at the lower part of the wall of the waste water treatment barrel. Using the water pressure difference, the treated water enters the water treatment and purification equipment, and the purification rate is high. In the process of treatment, the industrial paint wastewater treatment device is filtered three times and purified twice, which improves the purification rate of industrial paint wastewater. The treatment capacity is large, and it is not easy to cause blockage. The rotation of the filter plate, quartz sand filter plate, and oil-absorbing cotton filter plate improves the treatment rate of sewage, and at the same time increases the treatment capacity of sewage, which solves the problem of discharging industrial wastewater with oil pollution into the water body in the above background technology, and the oil pollution covers the water surface. Prevent the oxygen in the air from dissolving into the water. The low oxygen content in the water body will hinder the photosynthesis of aquatic plants and cause the death of aquatic animals due to hypoxia. Oily wastewater will enter the soil, hindering the reproduction of microorganisms in the soil and destroying the soil layer. Aggregate structure, and industrial paint wastewater also contains a large amount of heavy metal particle impurities. Industrial paint wastewater with heavy metal particle impurities discharged into the water body will cause heavy metals in the water body and the soil around the water body to seriously exceed the standard, resulting in a large number of deaths of animals and plants in the water. It leads to the deterioration of the human living environment. Therefore, the industrial paint wastewater containing a large amount of solid particle impurities and oily suspended matter must be treated before it can be discharged. If the industrial paint wastewater cannot be effectively treated, it will not only waste water resources but also seriously deteriorate the water environment. , the smell of sewage spreads, flies breed, and it is easy to spread diseases and affect the quality of life of nearby residents. However, the current industrial paint wastewater device has a small amount of industrial paint wastewater treatment, which is easy to cause blockage.
