An industrial waste water discharge purification recycling device

Abstract

The invention relates to the field of industrial wastewater treatment devices, in particular to an industrial wastewater discharge purification and recycling device, which includes a box body, a screening structure, a filtering structure, a cleaning structure, a collecting structure, a lifting structure and a limiting structure; The setting can pre-screen the massive stone debris in the stone cutting wastewater, so as to prevent the massive debris from entering the subsequent process and increase the processing pressure of the subsequent process, so as to increase the efficiency of wastewater purification treatment, and in The screening structure can simultaneously drive the filter structure to work while performing the screening work. Through the work of the filter structure, the mud in the wastewater can be further filtered, so as to ensure the treatment efficiency of the wastewater and facilitate the reuse of the wastewater. The filter structure is in the While working, it can also act on the cleaning structure. Through the setting of the cleaning structure, the mud filtered on the filter structure can be scraped and collected to avoid blockage of the filter structure.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment devices, in particular to an industrial wastewater discharge purification recycling device. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that cannot be purified and treated to a certain standard after primary pollution. Industrial wastewater (industrial waste water), refers to the waste water and waste liquid discharged during the process of production, which contains industrial production materials lost with water, intermediate products, by-products and pollutants generated in the production process, which cause environmental pollution, especially water pollu...

AI Technical Summary

Problems solved by technology

Although the treatment of industrial wastewater started as early as the end of the 19th century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved.

[0003] In the industrial production and processing of stone slabs, in order to process the stone slabs into various shapes, it is generally necessary to cut the stone slabs. In order to ensure that the cutting blades will not be damaged due to high temperature during cutting, tap water is generally used to purge the cutting knives during cutting. Perform flushing work to achieve the effect of cooling, which will generate a large amount of wastewater. In general wastewater treatment, it is directly filtered with a filter before use, but some blocky stone debris is also used if it is also with the wastewater Into the treatment box, it will seriously affect the efficiency of filtration
