Photocatalytic reaction tank

Abstract

The invention discloses a photocatalytic reaction tank. The photocatalytic reaction tank comprises a reaction tank, wherein the upper end of the reaction tank is opened; the opening position of the upper end of the reaction tank is buckled with an upper sealing cover; the bottom part of the reaction tank is welded with support legs; the inner side of the reaction tank is welded with a horizontally-arranged solid-state garbage bearing plate; water leakage holes, of which the upper parts and the lower parts penetrate through each other, are uniformly formed in the solid-state garbage bearing plate; solid-state garbage falls down due to self-weight and a combined action with shifting forks, the scattering effect on the solid-state garbage which are stacked together can be realized, and the solid-state garbage which is dispersed simultaneously can be irradiated by ultraviolet lamp preferably, so that a photocatalyst in the solid-state garbage produces stronger oxidizability, quick oxidative decomposition of organic wastes in the solid-stage garbage can be realized, and the influence on the solid-state garbage caused by organic wastes can be avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a photocatalytic reaction tank. Background technique [0002] The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] Surface water pollution is obvious, but groundwater pollution is shocking. Among China's 1.3 billion population, 70% drink groundwater, and more than 400 of the more than 660 cities use groundwater as their drinking water source. However, according to reports, 90% of the country's urban groundwater has been polluted. [0004] Another set of data also shows that groundwater is facing serious challenges. In 2011, 9 provinces...

AI Technical Summary

Problems solved by technology

[0006] A common problem in sewage treatment is that solid waste exists in sewage. Although these wastes can be burned through separation, the burning method is unrealistic for the initial treatment of sewage. Therefore, it is very important to treat organic matter in such waste. difficulty
