Problems solved by technology

Wet oxidation technology still has certain limitations in practical application. It needs to be carried out under high temperature and high pressure conditions, so the reaction equipment is required to be resistant to high temperature, high pressure and corrosion, so the equipment cost is large and the investment is large.

Embodiment Construction

[0019] See figure 1 Shown: the present invention comprises wastewater treatment acoustic wave electro-oxidation process, and its steps are:

[0020] (1) The sewage enters the body of the ultrasonic sterilizer through the water inlet, and the ultrasonic wave with a control frequency above 40-120KHZ has the functions of cavitation, mixing, cracking, oxidation, pushing flow, sterilization, algae killing, cleaning, descaling, and ultrasonic wave on the sewage. Cavitation assists in sterilization and degradation of organic matter, so that water and oxidants can fully and evenly contact to achieve the purpose of degrading pollutants.

[0021] (2) Combining with oxidants to further carry out broad-spectrum sterilization. After bacteria, viruses, algae, and organisms in the water are subjected to a certain dose of oxidants, the DNA and RNA structures of their cells cannot be regenerated, and bacteria and viruses lose their ability to replicate themselves. To achieve the effect of ste...

Abstract

The invention relates to the technical field of waste water treatment and particularly relates to a sound wave electrooxidation process for the waste water treatment. The sound wave electrooxidation process for the waste water treatment comprises the following steps of: feeding sewage into an engine body of an ultrasonic wave sterilizer from a water inlet, carrying out cavitation, mixing, splitting, oxidation, flow pushing, sterilization, algae removal, washing and descaling on the sewage by ultrasonic waves with the frequency being higher than 40-120 KHz and electrooxidation, wherein the sterilization and organic matter degradation can be achieved by utilizing the ultrasonic wave cavitation and oxidization; enabling water to come into adequate and uniform contact with an oxidizing agent, so as to achieve ring opening and chain scission effects. The sound wave electrooxidation process has the advantages of operation stability, simplicity and convenience in operation, small occupied space, energy conversation and convenience in scientific management.

Description

Technical field: [0001] The invention relates to the technical field of waste water treatment, in particular to the sonic electro-oxidation process for waste water treatment. Background technique: [0002] With the rapid development of my country's industry and the development plan of the National Day, the requirements of my country's environmental protection cause, my country's industrial sewage discharge is facing a huge opportunity for development. The current development of circular economy is of great significance to improving resource utilization and building a resource-saving and environment-friendly society. Resource reduction, reuse, and recycling are the three basic principles of implementing circular economy, comprehensive utilization of resources, and clean production. They are also the inevitable requirements for environmental pollution prevention and control to shift from end-to-end control to front-end control and to achieve sustainable social and economic dev...
