Photocatalytic degradation device and use method thereof

Abstract

The invention provides a photocatalytic degradation device and a use method thereof. The device comprises a first sewage tube, wherein the first sewage tube is correspondingly connected with a physical degradation unit; the physical degradation unit is provided with a plurality of first liquid guide tubes; the plurality of first liquid guide tubes are all provided with first electronic valves; thefirst liquid guide tubes are correspondingly connected with photocatalytic units; two second liquid guide tubes are arranged below each photocatalytic unit; one second liquid guide tube is correspondingly connected with a first screening device; the first screening device is internally provided with a first water sucking motor; the first water sucking motor is connected with a third liquid guidetube; the third liquid guide tube is correspondingly connected with a rotational sampling device; the rotational sampling device is provided with a first controller; the first controller is connectedwith the second electronic valves on the two second liquid guide tubes in a control manner; the other second liquid guide tube is correspondingly connected with a second screening device; and the second screening device is correspondingly connected with a water drainage structure. Due to coactions of multiple units, both the purification precision and continuous degradation can be ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and mainly relates to a photocatalytic degradation device and a use method thereof. Background technique [0002] Photocatalytic reactions can decompose a variety of organic substances of environmental concern, and can also be used for disinfection and decolorization. It is worth mentioning that photocatalysis can completely degrade many substances, and the final products except CO and H 2 In addition to O, the halogens, sulfur, phosphorus, and nitrogen contained in the initial pollutants are converted into X-, SO 4 2- 、PO 4 3- , NO 3 - Such as inorganic salt ions, greatly reducing or even completely eliminating the harmfulness, so as to achieve the purpose of governance. [0003] The photocatalytic process is equally capable of treating other polluting metals. Photocatalysis can also degrade highly toxic pollutants such as cyanide. However, in the experimental process of photoc...

Problems solved by technology

[0005] The present invention provides a photocatalytic degradation device and its use method to solve the problem in the background art that due to the large amount of sewage produced, the sewage is always introduced in the process of treatment, and at the same time, the materials in part of the sewage cannot It is degraded by oxidation-reduction reaction. If a single photocatalyst is used for oxidation-reduction reaction, it will cause incomplete degradation, and when it is targeted for treatment, it will cause complex technical problems in the process.
