Multi-stage purification treatment system for industrial wastewater

Abstract

The invention discloses an industrial wastewater multi-stage purification treatment system which comprises a filtering box body, the left side and the right side of an inner cavity of the filtering box body are respectively provided with a filtering cavity and a filter residue collecting cavity, the middle part of the filtering cavity is sequentially provided with a plurality of groups of filtering mechanisms from top to bottom, the bottom of the filtering cavity is provided with a wastewater collecting barrel, and the wastewater collecting barrel is arranged below the filtering mechanisms; a filter residue discharging pipeline is arranged at the right part of the filter residue collecting cavity, a plurality of groups of filter residue collecting hoppers are communicated with the left side of the filter residue discharging pipeline, and a cleaning mechanism is arranged at the left part of the filter residue collecting cavity. And the right side of the inverted-cone-shaped water receiving barrel is positioned at the filter residue collecting hopper, so that the function of automatically removing the waste residues is realized, the internal waste residues do not need to be removed and cleaned by workers, the labor cost is reduced, and the working efficiency of filtration is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a multi-stage purification treatment system for industrial wastewater. Background technique [0002] The existing multi-stage purification and treatment system for industrial wastewater still has many problems. For example, after multiple sets of filters filter impurities, the impurities on the filter cannot be cleaned quickly and effectively. After long-term use, the filter is easy to be blocked, which will lead to equipment The filtration work cannot be carried out. When cleaning, the operator generally needs to disassemble and clean the equipment, which repeatedly wastes working time, increases the labor intensity of workers, and reduces work efficiency. [0003] Therefore, we propose a multi-stage purification treatment system for industrial wastewater to solve the above problems. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least o...

Problems solved by technology

[0004] The present invention aims to at least solve one of the technical problems in the prior art; for this reason, the present invention proposes a multi-stage purification treatment system for industrial waste water, which is used to solve the problem that the existing multi-stage purification treatment system for industrial waste water cannot quickly and effectively Clean up the impurities on the filter net, causing the filter net to be easily blocked. Manual disassembly and cleaning will waste working time, increase the labor intensity of workers, and reduce the technical problems of work efficiency.
