Problems solved by technology

[0004] 1) In the process of filtering industrial wastewater, there will be more impurities or wastewater oil film to block the filter structure, thereby affecting the normal operation of the entire treatment device and reducing the treatment efficiency of industrial wastewater;
[0005] 2) When adding a flocculant to treat industrial wastewater, the stirring structure used cannot make the flocculant fully contact with the wastewater, thus greatly slowing down the rate of sewage flocculation, which cannot meet people's needs

Embodiment Construction

[0040] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and To facilitate its practice, but not as a limitation of the invention.

[0041] See attached Figure 1-11 Shown, a kind of industrial wastewater treatment method, its treatment method specifically comprises the following steps:

[0042] S1. Filtration through the filter structure: the sewage to be treated is added to the inside of the box body 1 through the water inlet pipe 13, and the waste water can be preliminarily filtered through the filter structure to remove the impurities contained in it;

[0043] S2. Adding flocculant: the filtered industrial wastewater flows into the bottom of the box body 1 through the through hole 15, an...

Abstract

The invention discloses an industrial wastewater treatment method, and particularly relates to an industrial wastewater treatment device. The device comprises a box body, a filtering structure arranged in the box body and used for filtering wastewater, and a stirring structure arranged in the box body and used for mixing wastewater, wherein the outer wall of the top of the box body is in pluggingconnection with a water inlet pipe; moreover, an inclined rod is arranged on the outer wall of the bottom of the box body, a flow dividing plate is arranged on the outer wall of one end of the inclined rod, flow dividing holes distributed at equal intervals are formed in the outer wall of the top of the flow dividing plate, the specifications of the flow dividing holes are gradually increased fromthe middle of the flow dividing plate to the two ends, and the flow dividing holes are located above the filtering structure. Wastewater in the sealing plate can be fully stirred in the transmissionprocess of the transmission belt, and meanwhile, an M-shaped stirring path is formed in the stirring process of the transmission belt, so that the stirring range of the device on the wastewater is expanded, and the wastewater is in more sufficient contact with a flocculating agent.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an industrial wastewater treatment method. 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 wastewater contains Contains various pesticides, etc. [...
