Embodiment Construction

[0020] The invention is a combination technology of microwave-ultraviolet photocatalytic oxidation-electrochemical oxidation to treat and reuse high-temperature dyeing wastewater.

[0021] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0022] 1. Treatment and reuse method of high temperature dyeing wastewater

[0023] Specific steps are as follows:

[0024] After filtering the high-temperature dyeing wastewater with a sand filter, the high-temperature dyeing wastewater is filtered with a sand filter, and then enters the photocatalytic reactor;

[0025] Adding an oxidizing agent to carry out microwave degradation and photocatalytic oxidation with extreme ultraviolet light;

[0026] In the process of photochemical reaction, air is blown in, and ultraviolet light is generated under the excitation of microwaves. The air generates ozone under the strong catalysis of ultraviolet light, and ozone cooperates wit...

Abstract

The present invention relates to a method for treating, recovering and reusing high-temperature dyeing waste water by utilizing combined application technique of microwave-UV-light photocaltalytic oxidation-electrochemical oxidation. Said method includes the following concrete steps: filtering waste water, photocatalytic reaction, microwave degradation, microwave excitation, adding oxidant and active carbon and making chemical reaction etc.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a treatment and reuse method for high-temperature dyeing wastewater. Background technique [0002] The textile printing and dyeing industry is a large discharge of industrial wastewater, but also a large user of water. As the demand for water in the textile industry increases and the supply decreases, the reuse of textile wastewater in production has become one of the difficulties faced by the textile printing and dyeing industry, and it is also an important technical research project that the textile printing and dyeing industry needs to carry out. [0003] The main factors affecting the reuse of printing and dyeing wastewater are suspended solids, chroma, participating organic matter and non-oxidative properties of wastewater. The reuse of printing and dyeing wastewater is carried out according to the technical requirements of printing and dyeing wastewater, which is discharged...
