Problems solved by technology

[0005] Synergistic ozonation technology has not yet entered the field of oilfield sewage treatment. Due to the high chemical oxygen demand, salinity, and suspended solids in this part of the sewage, it is difficult to degrade in the natural environment, and it is easy to damage the surrounding soil, crops, and surface water systems. Cause serious pollution, a single ozone oxidation technology is difficult to meet the requirements
At the same time, the road conditions in the oilfield development area are limited, and most of them are remote mountainous areas. Large fixed devices are not suitable for sewage treatment in this field.

Abstract

The invention discloses an ozone oxidation reactor. The ozone oxidation reactor comprises a tank body and a water inlet pipe communicated with the tank body. The water inlet pipe is provided with a water inlet and an ozone inlet. Ozone is fed in the ozone inlet. A hydrodynamic cavitation device allowing water and the ozone to generate hydrodynamic cavitation is arranged in the water inlet pipe. Ultrasonic oscillators allowing the water and the ozone to generate ultrasound cavitation are arranged in tank body and connected with an ultrasonic generator. A cavity of the tank body is filled with catalysts for motivating the ozone to generate hydroxyl radical. According to the ozone oxidation reactor, ozone oxidation is combined with an ultrasonic cavitation technology and a hydrodynamic cavitation technology to form a synergetic catalytic ozonation technology, the hydroxyl radical with the higher oxidation performance and lower reaction selectivity is generated, the oxidation potential of the hydroxyl radical can reach 2.8 V, the hydroxyl radical can generate a chain reaction with most of organic pollutants unselectively, hazardous substances are converted into CO2, H2O and mineral salt, the chemical oxygen demand is lowered, and meanwhile secondary pollution is avoided.

Description

technical field [0001] The invention relates to the field of oilfield sewage treatment equipment, more specifically, the invention relates to an ozonation reactor for treating oilfield sewage by using hydraulic cavitation and ultrasonic cavitation technology to catalyze ozone. Background technique [0002] Ozone is a strong oxidizing agent with an oxidation potential of 2.07V and strong oxidizing properties. After the reaction, the ozone is converted into oxygen and diffused into the air without pollution. It is a green and environmentally friendly oxidant. Ozone has been widely used in the field of sewage treatment, but its chemical properties are unstable and its decomposition rate is fast. It can only be used in time after generation, and it is not suitable for storage and transportation. At the same time, it is selective for ions and has low treatment efficiency. . [0003] At present, the function of the domestic ozone oxidation reactor is relatively single, which can...
