A centrifugal jet device used in sewage treatment process

Abstract

A disclosed centrifugation jet apparatus applied to sewage processing comprises a sewage inlet port, a throat port, a self-oscillation chamber, a throat path, a mixing chamber and a mixed-water outlet pipe which are successively connected from left to right; the internal diameter at the left part of the throat port is larger than the internal diameter at the right part; a position, close to a water inlet, at the left end of the throat port is provided with an air inlet, and the sewage inlet port is connected with the water inlet at the left end of the throat port; the self-oscillation chamber is in the shape of a concave body inverted to the right side, and a water inlet at the left side of the self-oscillation chamber is connected with the throat port; the middle part of the right side of the self-oscillation chamber is connected with one end of the throat path, and the other end of the throat path is connected with a water inlet of the mixing chamber; an ozone water inlet port is arranged beside the water inlet of the mixing chamber; and a water outlet at the right side of the mixing chamber is connected with the mixed-water outlet pipe. According to the centrifugation jet apparatus, a high-speed fluid is utilized to entrain a low-speed fluid for realizing supercharging and mixing processes, full uniform mixing of ozone water and sewage is guaranteed, and then the mixed water enters a reaction chamber for reaction, so that sterilization effect is realized, and the centrifugation jet apparatus is simple in structure and easy for operation.

Description

technical field [0001] The invention relates to a centrifugal jet device, in particular to a centrifugal jet device used in the sewage treatment process. Background technique [0002] With the development of industrialization and urbanization, the pollution of water environment and the shortage of water resources are becoming more and more serious. The control of water pollution and the protection of water environment are urgent. [0003] The current water treatment methods are: (1) sediment filtration method, (2) hard water softening method, (3) adsorption method, (4) deionization method, (5) reverse osmosis method, reverse osmosis method; (6) ultrafiltration (7) distillation method, (8) disinfection method, (9) biochemical method, etc., and the most novel (10) forward osmosis method and natural purification method. [0004] The above traditional sewage treatment methods, even if the discharge reaches the standard, are a waste of water resources. If general technology is ...

Problems solved by technology

[0007] One of the key technologies of ozone treatment is to make ozone and sewage fully and evenly mixed. At present, ozone is directly pressurized and passed into water for dissolution to obtain ozone water, and then the ozone water is directly passed into sewage, which cannot guarantee Ozone can fully mix with sewage
