Description

Technical Field

[0001] The present invention relates to the technical field of industrial wastewater treatment, and in particular to an intelligent catalytic oxidation device for industrial wastewater based on the Internet of Things. Background Art

[0002] The Internet of Things refers to connecting any object to the network through information sensing equipment according to the agreed protocol. Objects exchange and communicate information through information transmission media to realize intelligent identification, positioning, tracking, supervision and other functions. Industrial wastewater refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediates, by-products and pollutants generated in the production process that are lost with water. Since industrial wastewater is directly discharged into the natural environment, it will cause environmental pollution and damage. Nowadays, the industrial wastewater generated is usually treated in combination with the Internet of Things technology before being discharged to reduce the pollution and damage to the environment. When treating industrial wastewater, catalytic oxidation treatment of industrial wastewater is one of the essential treatment processes. When catalytic oxidation treatment of industrial wastewater is carried out, it is necessary to add an appropriate amount of oxidant liquid to the industrial wastewater so that the oxidant liquid is mixed with the industrial wastewater and a catalytic oxidation reaction occurs.

[0003] However, in the prior art, the commonly used intelligent catalytic oxidation equipment for industrial wastewater based on the Internet of Things requires staff to manually add an appropriate amount of oxidant liquid into the industrial wastewater for mixing when in use. The operation process is cumbersome, time-consuming and labor-intensive. In addition, during the catalytic oxidation treatment of industrial wastewater, the fluidity of the industrial wastewater is poor, and the oxidant liquid and the wastewater cannot be fully mixed, resulting in poor quality of the catalytic oxidation treatment of the industrial wastewater and failing to achieve the ideal wastewater treatment effect. To this end, we propose an intelligent catalytic oxidation equipment for industrial wastewater based on the Internet of Things to solve the above problems. Summary of the invention
