Ozone adding device used in sewage treatment process

Abstract

The invention provides an ozone adding device used in a sewage treatment process. The device comprises a dissolved air tank and an ozone treatment tank, and the dissolved air tank and the ozone treatment tank are connected through a water inlet pipe; a water inlet of the dissolved air tank is connected with a sewage pipe, an ozone recovery assembly is further arranged above the sewage pipe, an ozone adding pipe is arranged in the ozone treatment tank, and the ozone recovery assembly is connected with the ozone adding pipe; a sewage inlet pipe is further connected with a jet device, the jet device is connected with an air inlet pipe, and an included angle smaller than 90 degrees is formed between the axis of the air inlet pipe and the axis of the jet device body. According to the ozone adding device used in a sewage treatment process, the jet device of which the inner wall is provided with a baffle plate which is of a spiral structure and protrudes inwards is provided. Sewage rotates under the action of the threads, disturbance of fluid near the inner wall face of the jet device is enhanced, and ozone gas fed into the jet device through the ozone feeding pipe can be taken away in time by liquid moving in a rotating mode.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an ozone dosing device used in the sewage treatment process. Background technique [0002] At present, the ozone is not fully utilized in the dosing process in the existing wastewater treatment process. At the same time, the ozone generated from the generator is directly put into the sewage, resulting in too large ozone bubbles, resulting in insufficient contact area between ozone and water per unit volume. , most of the ozone is discharged into the air without fully reacting with the sewage, resulting in a waste of resources; at present, the scraper height of the existing scum scraping mechanism installed above the sewage treatment tank is fixed, and when the water level changes , it is impossible to adjust the vertical position of the scraper according to the real-time water level to adapt to different water levels; the current structure of the existing ejector is unreasonable, ...
