Environment-friendly printing wastewater treatment equipment

Abstract

The invention discloses environment-friendly printing wastewater treatment equipment. The equipment comprises a treatment tank, a collecting box, a first cleaning scraper blade, a second cleaning scraper blade and a cleaning scraper blade auxiliary mechanism, by arranging the first cleaning scraper blade and a collecting box, flocculent impurities on the surface of the wastewater in the treatmenttank can be well removed, and can be well collected for centralized treatment, so that waste of wastewater material resources is avoided, and the working efficiency of wastewater treatment is improved; in the process, an intercepting filter screen is driven by a telescopic rod to move upwards, the flocculent impurities in the wastewater can be separated out to the maximum extent, then the workingquality of a wastewater pool is guaranteed, the working economic benefits are guaranteed, a good auxiliary effect is achieved on the first cleaning scraper blade for scraping the flocculent impuritieson the intercepting filter screen, one-time cleaning is more sufficient, therefore, workload is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to an environment-friendly printing wastewater treatment equipment. Background technique [0002] Wastewater treatment methods Modern wastewater treatment methods are mainly divided into three categories: physical treatment, chemical treatment and biological treatment. Physical treatment is a wastewater treatment method that separates and recovers unresolved suspended pollutants (including oil film and oil beads) in wastewater through physical action, and can be divided into gravity separation method, centrifugal separation method and sieve retention method, etc.; it belongs to gravity The processing units of the separation method include: sedimentation, flotation (air flotation), etc., and the corresponding processing equipment is grit chamber, sedimentation tank, grease trap, air pool and its auxiliary devices, etc., among which the heat exchange principle-b...

Problems solved by technology

[0003] For the wastewater generated in the printing industry, a large amount of flocs will accumulate in the upper layer of the wastewater, which will affect its working process during the flotation (air flotation) work in the wastewater treatment process, and it will also affect the work of chemical and biological treatment methods. It will have an impact. For the chemical method, the chemical solution cannot be processed and mixed well with the wastewater, which will reduce the efficiency of the purification treatment. And for the biological treatment work, the accumulation of floating impurity flocs will affect the combination of biological purification and oxygen, reducing the treatment work. Efficiency, under the prior art, it is more troublesome to deal with its impurity flocs, and the environmental protection is poor. Therefore, the present invention proposes an environment-friendly printing wastewater treatment equipment to solve the above problems
