Embodiment 1

[0044] A preparation method containing three-dimensional zinc oxide filter screen, comprising the following steps:

[0045] S1, cleaning: choose nickel or copper or silver material as the substrate, and put the substrate material into acetone, ethanol, and deionized water in sequence for ultrasonic cleaning;

[0046] S2, placing the base material cleaned in step S1 in an oven to dry, and cooling for use;

[0047] S3, by the magnetron sputtering method, the zinc oxide target is hit on the cooled base material, in an atmosphere with a nitrogen-oxygen ratio of 5:50, and the atmosphere pressure is between 2 Pa, so that the base material grows and oxidizes Zinc seed layer; the seed layer is grown by magnetron sputtering, and the obtained zinc oxide nanorods have the advantages of uniform length, uniform thickness, regular and dense growth;

[0048]S4, growing zinc oxide nanorods on the basis of the seed layer formed in step S3 by a hydrothermal method to obtain a three-dimensional...

Abstract

The invention discloses a waste water treatment device based on three-dimensional zinc oxide and its use method, comprising a waste water treatment pipeline, a water inlet, a flow rate control device, a filter net containing three-dimensional zinc oxide, an ultraviolet lamp, a water outlet, a waste water pool, and a waste water pool Outlet valves, pumps and wastewater tank return valves, the wastewater passes through the filter screen containing three-dimensional zinc oxide, and the photocatalytic reaction of zinc oxide under the irradiation of ultraviolet light degrades the organic pollutants in the wastewater. When the concentration of organic pollutants in the wastewater When it is higher than the discharge standard value, close the outlet valve, open the return valve, start the pump, send the wastewater back to the water inlet, adjust the flow rate, repeat the photocatalytic reaction, and degrade again to realize the multiple recycling of the wastewater treatment network, reaching The effect of efficient wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment in environmental protection, and in particular relates to a wastewater treatment device based on three-dimensional zinc oxide and a method for using the same. Background technique [0002] Wastewater treatment is a major problem to be solved urgently in environmental protection projects. Traditional water treatment methods are not only inefficient and costly, but also may have problems such as secondary pollution. However, the development and application of nanotechnology is likely to completely solve this problem. [0003] In the existing nanotechnology research, photochemical and photocatalytic oxidation is an advanced oxidation technology that has been studied more. The so-called photocatalytic reaction is a chemical reaction under the action of light; a photochemical reaction requires molecules to absorb electromagnetic radiation of a specific wavelength, stimulated to generate mo...
