Deep purification and reclaiming device and method for dyeing waste water

Abstract

The invention discloses a deep purification and reclaiming device and method for dyeing waste water, wherein the device comprises a regulating reservoir, an naerobic tank, an aerobic aeration tank, a sedimentation tank, a chlorine peroxide oxidation tank, a medicament administration and coagulation tank, a biologically active charcoal tank and a fiber ball filter. The waste water treatment method integrates a biochemical treatment process and a physical-chemical treatment method.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment, in particular to a device for deep purification and reuse of printing and dyeing wastewater; the invention also relates to a method for deep purification and reuse of printing and dyeing wastewater. Background technique: [0002] The printing and dyeing industry is one of the major water users, and the wastewater discharged during the production process has high impurity content and large chroma, which seriously pollutes the receiving water body. On the other hand, the global water resource shortage is increasingly seriously affecting and restricting economic development. develop. Therefore, it has become an irreversible trend to carry out secondary reuse of deep purification of sewage. It can not only improve water utilization rate, save water resources, but also reduce discharge, protect water environment, achieve clean production, and maintain sustainable economic development.

AI Technical Summary

Problems solved by technology

[0003] The composition of printing and dyeing wastewater is complex, and its biochemical degree is often poor, but it is difficult to achieve the ideal treatment effect by simply using biochemical or physical chemical methods. The feasibility is poor, so that the wastewater purification and reuse technology lacks operability in reality and cannot be promoted on a large scale
