Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a photocatalytic oxidation reactor and a sewage treatment system. The photocatalytic oxidation reactor comprises a housing, an ultraviolet lamp and a partition assembly, wherein the partition assembly is matched with the wall of the housing to form a grid structure; a plurality of first partitions of the partition assembly are matched with the wall of the housing to form a plurality of sequentially arranged grid strips; first communicating holes of every two adjacent first partitions are arranged in a staggered manner; each grid strip is partitioned into a plurality of grids by the plurality of second partitions; second communicating holes of each first partition communicate with two adjacent grids in the same grid strip; grids at one end of two farthest grid strips communicate with a water inlet and a water outlet respectively; the first communicating hole and the water inlet are located at two ends of the grid strip communicating with the water inlet; and the first communicating hole and the water outlet are located at two ends of the grid strip communicating with the water outlet. The photocatalytic oxidation reactor has relatively high purification efficiency and a relatively good purification effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a photocatalytic oxidation reactor and a sewage treatment system. Background technique [0002] Photocatalytic oxidation technology mainly uses ultraviolet light to stimulate oxidation to convert O 2 、H 2 o 2 The combination of oxidant and light radiation is used to treat CHCl in sewage 3 , CCl 4 Due to its mild reaction conditions, easy control of operating conditions, strong oxidation ability, and no secondary pollution, photocatalytic oxidation technology has become a new water pollution treatment technology with broad application prospects. However, the current photocatalytic oxidation reactor still has the problems of low purification efficiency and insufficient purification effect. Contents of the invention [0003] Based on this, it is necessary to provide a photocatalytic oxidation reactor with high purification efficiency and good purification effect. [0004] A p...
