Problems solved by technology

However, for other types of industrial wastewater, the effect of this method is not satisfactory
[0005] Although the treatment cost of the precipitation method is relatively low, the capital investment of this method is large, the treatment volume is relatively small, and the treatment efficiency is low
[0006] Obviously, the technical effects of the above three methods for the treatment of industrial sewage are not very ideal

Embodiment Construction

[0018] The basic principle of the present invention is the photochemical oxidation method. The method of the present invention improves the rate of the oxidation reaction and the oxidation capacity under the combined action of chemical oxidation and light radiation. The photochemical oxidation method of the present invention uses ultraviolet light as the radiation source, and at the same time, a certain amount of oxidant and catalyst must be put into the water in advance. The invention has excellent removal effect on small molecular organic matter that is difficult to degrade and has toxicity. In addition, the photochemical oxidation reaction of the present invention generates many extremely active free radicals in water, and these free radicals can easily damage the structure of organic matter.

[0019] The technical solution of the present invention will be described in detail below with reference to the drawings. Wherein, the same reference numerals are used to represent the...

Abstract

The invention brings forward a treating method for industrial waste water by using ultraviolet light for catalytic oxidation. The method comprises the following steps: adding a catalyst into industrial waste water; generating ultraviolet light; irradiating industrial waste water containing the catalyst with the generated ultraviolet light and carrying out a catalytic oxidation reaction. Compared to conventional treating methods for industrial waste water, the treating method provided in the invention at least has the advantages of reduction in secondary pollution and energy consumption, simple operation, etc.

Description

Technical field [0001] The invention relates to sewage treatment technology, in particular to an industrial wastewater treatment method using ultraviolet light for catalytic oxidation. Background technique [0002] Environmental protection is an important issue facing human society today. In particular, the treatment of sewage formed in urban life and industrial production is currently the top priority of environmental protection. Generally, the current mainstream sewage treatment plants mainly adopt sewage treatment technologies such as filtration, coagulation and precipitation. [0003] The filtration method can only remove impurities, and has little effect on sewage with high chemical oxygen demand (COD) and biological oxygen demand (BOD), and the power consumption of filtration is high, and the cost of sewage treatment increases. [0004] Coagulation method is especially suitable for printing and dyeing wastewater produced in the printing and dyeing industry. However, for othe...
