Problems solved by technology

However, due to the shortcomings of the fiber membrane itself, its wide application in the advanced treatment of industrial wastewater and domestic sewage is limited.
First, the cost of membrane materials and membrane components is expensive and the life of the organic membrane is not long; second, to achieve the goal of high-efficiency separation, the effective pore size of the m

Abstract

The invention relates to a wastewater treatment and reuse process, which comprises the following steps: collecting sewage into an adjusting tank; transporting the sewage after being subjected to aeration agitation by using compressed air into an ozone mixing tank for further oxygenolysis; transporting the sewage into an ozone air floating water purifier for coagulation reaction again; then automatically decomposing ozone in a middle water tank; degrading organic matters in the sewage in a BAF biological filter tank; adding the sewage after being degraded and subjected to hybrid reaction with the ozone and medicaments in a pipeline blender into a floating sand filter; enabling a flocculent in the water after being entrapped by the foliating sand filter to flow into a water purifying storage tank for collection and production use; and coating the surface at the inner part of the ozone mixing tank and the surfaces of accelerant filling materials with nanometer titanium dioxide, so as to increase the contact area of the titanium dioxide and ultraviolet light and improve the oxidation effect; OH is generated by an ultraviolet ray and the ozone, and the strong oxidizing property thereof oxidizes difficultly decomposed macromolecular substances in the water into simple micromolecular substances.

Description

technical field [0001] The invention relates to a waste water treatment process, which is especially suitable for treating waste water produced in the printing and dyeing industry and reaches the production reuse standard. The waste water treatment and reuse process and its equipment belong to the technical field of environmental protection. Background technique [0002] Due to the "water crisis", many countries and regions are actively consolidating and strengthening water-saving awareness and researching industrial wastewater regeneration and reuse. Industrial wastewater reuse refers to the reuse of water used in industrial production processes after treatment. In the printing and dyeing industry, the dyes used are generally artificially synthesized chemical dyes. Due to the characteristics of various chemical dyes, complex structures, difficult decolorization, and poor biodegradability, the chromaticity of printing and dyeing wastewater has great impact on wastewater treat...
