Industrial wastewater discharging, purifying and recycling device

Abstract

The invention relates to the field of industrial wastewater treatment devices and relates to an industrial wastewater discharging, purifying and recycling device. The device comprises a box body, a screening structure, a filtering structure, a cleaning structure, a collecting structure, a lifting structure and a limiting structure; the screening structure is adopted, so that blocky stone chippingsin stone cutting wastewater can be screened out in advance, and therefore, the blocky chippings can be prevented from entering a subsequent process to increase the treatment pressure of the subsequent process, and the purification treatment efficiency of the wastewater can be improved; the screening structure can drive the filtering structure to work while carrying out screening work; the filtering structure can work, so that stone mud in the wastewater can be further filtered out, the treatment efficiency of the wastewater can be ensured, and the wastewater can be easily recycled; the filtering structure can further act on the cleaning structure while working; and with the cleaning structure adopted, the stone mud filtered out on the filtering structure can be scraped and collected, andthe blockage of the filtering structure can be avoided.

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
