Industrial sewage treatment equipment and use method thereof

Abstract

The invention discloses industrial sewage treatment equipment and a use method thereof, belongs to the technical field of sewage treatment. The industrial sewage treatment equipment comprises a hard plastic cylinder and flocculation balls for flocculation, and each flocculation ball comprises a hollow plastic ball and a mounting cylinder arranged in the hollow plastic ball. The plurality of flocculation balls are driven to do irregular multi-angle free movement in industrial sewage by utilizing the acting force among the flocculation balls, so that an organic flocculation functional membrane is in full contact with the industrial sewage, the necessary stirring procedure in the flocculation process in the prior art is replaced, the cost of flocculation equipment is reduced, meanwhile, the phenomenon of scattering of flocculation gel lumps caused by shearing force generated by stirring of a stirring rod is avoided, the sewage flocculation efficiency is greatly improved, and after flocculation is finished, the multiple flocculation gel lumps can be adsorbed together and sink to the bottom in the hard plastic cylinder, so that sewage and the flocculation gel lumps are conveniently separated and collected.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to an industrial sewage treatment equipment and a method for using the same. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, 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 manufacturing industrial wa...

Problems solved by technology

[0004] The flocculation in the prior art generally puts organic or inorganic flocculants into the industrial sewage, and then quickly stirs the industrial sewage with the flocculants, so that the flocculants are fully contacted to produce flocculation gel groups, and in the process of stirring flocculation , due to the shear force of the stirring rod, the flocs produced by flocculation will break up, which will affect the flocculation effect and flocculation efficiency. Large, increasing the cost of sewage treatment
