Industrial sewage treatment device and use method thereof

Abstract

The invention relates to the technical field of industrial sewage, and in particular, relates to an industrial sewage treatment device and a use method thereof. The invention aims to solve the technical problems that physical impurities exist in sewage, fine suspended solids and dissolved organic matters are not treated, and sludge exists. For solving the technical problems, the invention provides the industrial sewage treatment device and the use method thereof, wherein the industrial sewage treatment device is composed of a base, a settling tank, a filtering mechanism, a feeding mechanism and a desilting mechanism; first-time filtering is conducted through a filtering net plate, physical impurities in sewage are filtered out, and influences on sewage treatment in the later period are avoided; the device is provided with the feeding mechanism, so that the full combination reaction of alum and chemical wastewater is enhanced, the floc precipitation speed is increased, and the working efficiency of the device is enhanced; and the device is ingenious in design, manual treatment is not needed, sludge on the inner wall of the bottom of the settling tank is scraped through a push block, sludge in the device is conveniently removed, the service life of the device is prolonged, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an industrial sewage treatment device, in particular to an industrial sewage treatment device and a method for using the same, belonging to the technical field of industrial sewage. Background technique [0002] Industrial sewage includes production sewage, domestic sewage and cooling water. It refers to the waste water and waste liquid produced in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide m...

AI Technical Summary

Problems solved by technology

The invention has high degree of automation and strong practicability. It can not only accelerate the precipitation of impurities and silt in industrial sewage, improve the efficiency of sewage treatment, but also can conveniently and quickly discharge the impurities and silt on the vibrating plate, which is convenient for people to use. The inventor realized In the process of this scheme, it is found that the following problems in the prior art have not been well resolved: 1. The invention does not filter other substances in the sewage before processing, which will cause slow processing and low work efficiency. During the process, the water quality cannot be purified, and the harmful odor in the industrial sewage cannot be treated, which will cause harm to the life and health of the staff; 2. The invention does not target fine suspended matter and dissolved organic matter during the treatment process, and
