Ultraviolet-sunlight combined purifying device for water purification

Abstract

The invention provides an ultraviolet-sunlight combined purifying device for water purification. The ultraviolet-sunlight combined purifying device comprises a device body, a water feed unit arranged at the bottom part of the device body, an ultraviolet combined catalytic oxidation unit arranged in the device body, and an overflow oxygenating-sunlight catalytic oxidation unit arranged at the outer side wall of the device body, wherein the water feed unit is connected to the ultraviolet combined catalytic oxidation unit; the water outlet of the ultraviolet combined catalytic oxidation unit is positioned at the top part of the device body; the ultraviolet combined catalytic oxidation unit comprises a group of tubular reactors arranged in parallel; a scrap iron catalytic reaction layer is arranged at the lower part of each tubular reactor, an immobilized titanium dioxide catalytic reaction layer is arranged at the middle part of each tubular reactor, and a group of parallel ultraviolet tubes are arranged in each tubular reactor. The device is easy to operate, convenient to use, flexible in operation, good in purification effect, low in energy consumption and low in treatment cost, thereby having better popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of water body purification devices, in particular to an ultraviolet-sunlight combined purification device for water body purification. Background technique [0002] At present, natural rivers, artificial lakes, and artificial rivers in China are all in different degrees of pollution. Most water bodies are mainly in the state of eutrophication. Black and smelly phenomenon. Therefore, it is an urgent need for most cities in China to rationally treat and dispose of water pollution characteristics, effectively remove specific pollutants in water, and improve water quality. [0003] At present, there are many ways to improve the water quality of polluted water bodies. Using biological effects such as ecological floating beds, ecological wetlands, etc.; using physical effects such as filtration, falling water, etc.; using chemical effects such as adding algicides, precipitants, etc.; using physical and chemical effects su...

AI Technical Summary

Problems solved by technology

However, the above-mentioned methods mostly treat water bodies through a single mechanism of action, the synergistic effect between different treatment methods is weak, and the operation method is single, so the treatment effect is relatively poor, and it is difficult to meet the water body treatment needs under various conditions
