Immersed type photoelectrocatalysis reaction apparatus

Abstract

The invention relates to an apparatus used for sterilizing, removing algae and purifying water quality, and especially relates to an immersed type photoelectrocatalysis reaction apparatus. The photoelectrocatalysis reaction apparatus comprises various roots of photoelectrocatalysis pipes, the photoelectrocatalysis pipes are respectively connected with an outlet pipe and an inlet pipe. The immersed type photoelectrocatalysis reaction apparatus is formed by independent photoelectrocatalysis pipes, the reaction apparatus with different sizes having different numbers of photoelectrocatalysis pipes can be produced according to different water body area and water quality condition, the pipe number can be set in an adjustable mode, and can be 4, 8 and the like (4n, n>=1). According to the invention, TiO2 is employed to prepare a film, the disadvantages that nano powder is not easy to separate with the water body can be overcome, a lot of engineering practices prove that the photoelectrocatalysis reaction apparatus has simple structure, the treatment effect is good, the operation is simple, no secondary pollution is generated, and the photoelectrocatalysis reaction apparatus is effective to remove the algae of the eutrophication water body. The photoelectrocatalysis reaction apparatus has the advantages of compact structure, less land occupation area, less energy consumption, no chemical agent addition, low operation cost and large treatment amount.

Description

technical field [0001] The invention relates to a device for sterilizing, removing algae and purifying water, in particular to a submerged photoelectric catalytic reaction device. Background technique [0002] The photoelectric catalytic reaction device is a device that uses the principle of photocatalytic reaction to sterilize, weed and purify water. Photocatalysis refers to the process in which nano-semiconductor materials promote the decomposition or synthesis of compounds under the irradiation of light, in which TiO 2 It has become the focus of photocatalytic research because of its high catalytic activity, good stability, non-toxicity to the human body, continuous light can maintain activity and other advantages. TiO 2 Photocatalytic performance has the ability to purify almost all organic pollutants. The 114 kinds of organic pollutants announced by the US Environmental Protection Agency are treated with TiO under light. 2 As a catalyst, it can be gradually degraded...

Problems solved by technology

However, due to the TiO used in the photocatalytic reaction 2 The powder is easy to coagulate in the suspension system, and it is difficult to separate and recover, and it is easy to be poisoned, which is not conducive to the regeneration of the catalyst. This is based on TiO 2 One of the main reasons why it is difficult for large-scale application of photocatalytic methods based on
