Problems solved by technology

[0003] Ozone oxidation or ozone catalytic oxidation currently mainly uses perforated tubes or microporous aeration to pass ozone into sewage. Ozone forms large bubbles in sewage and has a low dissolution rate, resulting in low ozone utilization and low discharge. More ozone content in the exhaust
[0004] The main problems existing in the existing ozone catalytic oxidation reactor are: 1. After the reaction, the tail gas is not dissolved and the reacted ozone is not recovered, and it is discharged after being treated by the ozonizer, resulting in a waste of ozone and a low utiliz

Abstract

The invention provides an internal circulation catalytic ozonation sewage treatment device with good removal effect, and the device comprises a reactor; the bottom of the reactor is provided with a water-gas mixing inlet, the water-gas mixing inlet is communicated with a liquid inlet pipe, the liquid inlet pipe is provided with an ozone adding mechanism, and the upper part of the reactor is provided with a gas circulating mechanism and a sewage circulating mechanism; the gas circulating mechanism is communicated with the lower part of the reactor, the sewage circulating mechanism is communicated with the lower part of the reactor, an exhaust port is formed in the upper end of the reactor, a water outlet is formed in the upper part of the reactor, and a catalyst bed layer is arranged in thereactor. Sewage and ozone are mixed in advance, the reaction time is prolonged, the sewage and waste gas at the top of the reactor are recycled, the sewage passes through the catalyst bed layer for multiple times, the reaction time is prolonged, and the ozone using effect is better.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an internal circulation ozone catalytic oxidation sewage treatment device with good removal effect. Background technique [0002] With the increasing national environmental protection standards and the requirements for sewage reuse, the traditional sewage treatment technology has been difficult to meet the technical needs, thus the technical demand for advanced sewage treatment has been put forward. Advanced oxidation technology is a new water treatment technology that can generate strong oxidizing free radicals such as hydroxyl radicals during the reaction process, greatly improving the oxidation capacity and effectively degrading pollutants in water. As one of the advanced oxidation technologies, ozone oxidation or ozone catalytic oxidation has developed rapidly due to its good treatment effect and simple operation. Regardless of ozone oxidation or ozone cata...
