Catalytic ozonation sewage treatment equipment with built-in circulating flow guide structure

Abstract

The invention discloses catalytic ozonation sewage treatment equipment with a built-in circulating flow guide structure, which comprises a primary reaction box, a secondary reaction box, a gas connecting pipe, a sewage cleaning bin and a sewage connecting pipe. The bottom of the primary reaction box is fixedly connected with a base, the upper surface of the base is fixedly connected with the secondary reaction box, one side of the secondary reaction box is fixedly connected with a gas inlet pipe, and a one-way gas outlet pipe is arranged on one side of the gas inlet pipe. Through the arrangement of the primary reaction box, the secondary reaction box and the gas connecting pipe, gas is introduced from the gas inlet pipe on one side of the secondary reaction box so that high-concentration ozone reacts with sewage for the first time, when the ozone which reacts with the sewage for the first time enters the secondary reaction box through the gas connecting pipe, the ozone reacts with the sewage for the second time, the sewage enters the primary reaction box to react with residual oxygen and then enters the secondary reaction box through a flow guide pipe to react with pure ozone, so that the sewage reaction is more sufficient, and the reaction efficiency of the device is higher.

Description

technical field [0001] The invention relates to the technical field of ozone catalytic oxidation sewage, in particular to an ozone catalytic oxidation sewage treatment device with a built-in circulation diversion structure. Background technique [0002] In recent years, with the development of industry, new problems have emerged in water treatment and water pollution control. Due to the emergence of some biodegradable or toxic organic pollutants in industrial wastewater, such as pesticides, synthetic detergents and certain At the same time, in order to protect the environment and water resources and to be able to reuse the treated polluted water, environmental protection and related departments have formulated strict standards and laws. In many cases, industrial wastewater must go through three levels of advanced treatment. To meet the requirements of water pollution control and wastewater reuse, ozone treatment of wastewater, as one of the effective means of advanced wastew...

AI Technical Summary

Problems solved by technology

[0004] 1. In the prior art, when the ozone catalytic oxidation sewage treatment equipment treats sewage, most of the ozone is introduced into the sewage to make it react and catalyze the sewage. This method will make it difficult for the sewage to fully contact with the ozone, so that the reaction and oxidation of the sewage will be catalyzed. Insufficient, so that the sewage treatment effect of the device is not high;

[0005] 2. When the ozone catalytic oxidation sewage treatment equipment in the prior art treats difficult sewage, because the device itself does not have the sewage internal circulation technology, it needs to repeatedly discharge or inject sewage into the reaction tank, which reduces the working efficiency of the device. increased workload;

[0006] 3. In the prior art, the ozone catalytic oxidation sewage treatment equipment will produce a large amount of sediment or residue in the reaction device after a long time of sewage treatment. When the device is used for a long time, the pipeline in the device will be blocked. If necessary When cleaning the blockage in the device, it is necessary to disassemble the device, which is very troublesome, increases the workload and reduces the work efficiency
