Abstract

The invention discloses a nano material visible light degradation device as well as a preparation method and a degradation method thereof. The nano material visible light degradation device comprises a visible light source and a glass tube with a sealed end, wherein a nano material coating is arranged on the outer wall of the glass tube; the visible light source is arranged in the glass tube with the nano material coating; and the nano material coating is a graphite oxide / cadmium sulfide composite material. In the method, a nano material is in contact with a water sample but is not mixed with the water sample, and by virtue of visible light catalysis and photolysis technique, the problems in the prior art that the nano material needs to be separated from the water sample after photolysis and secondary pollution is caused because of incomplete separation are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a nanomaterial visible light degradation device, a preparation method and a degradation method thereof. 【Background technique】 [0002] The traditional sewage treatment technology is to decompose the organic pollutants in the water under the irradiation of ultraviolet light to achieve the decontamination effect. Recent nanotechnology uses visible light to catalyze the photolysis of organic pollutants. However, this technology must mix nanomaterials with water samples, and a process of separating water from nanomaterials is added after decontamination, which increases the difficulty and cost of decontamination, and limits the application of this nanotechnology to sewage treatment. 【Content of invention】 [0003] The purpose of the present invention is to provide a nanomaterial visible light degradation device and its preparation method and degradation met...
