Embodiment Construction

[0027] refer to figure 1 , a method for circulating ozone to purify sewage proposed by the present invention comprises the following steps.

[0028] S1. Install the reaction furnace 1, and vertically install the inner cylinder 2 connected at both ends and the outer cylinder 3 with the upper end sealed and the lower end open in the reaction furnace 1. The outer cylinder 3 is set on the outer circumference of the inner cylinder 2; the top of the inner cylinder There are gaps between the outer cylinder and the top of the outer cylinder, between the outer cylinder and the top of the reaction furnace, between the inner cylinder and the bottom of the reaction furnace, and between the outer cylinder and the bottom of the reaction furnace.

[0029] S2. Install a casing 4 outside the reaction furnace 1, the casing cooperates with the outer wall of the reaction furnace to form a closed decomposition chamber 4A, and install an ozone generator 5 in the decomposition chamber 4A.

Abstract

The invention discloses a method for circularly complementing ozone for purifying sewage. An oxygen-containing gas inside a decomposition cavity is decomposed into ozone under the action of an ozone generator; because of the heavy mass, the ozone sinks to the bottom of the decomposition cavity, is extruded into an ozone emission tube, diffuses into a reaction furnace through vent holes in the ozone emission tube and is mixed with sewage, and then harmful substances in the sewage can be oxidized. As oxygen can be generated after the ozone has oxidation reaction with the harmful substances in the sewage, an overflowing gas with oxygen and residual ozone overflows the surface of the sewage and is accumulated at the top of the reaction furnace, and is fed into the decomposition cavity through a gas guide tube. By adopting the method, reaction of the ozone and the sewage is relatively sufficient, the ozone utilization rate is increased, and the sewage purification effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a method for circulating ozone to purify sewage. Background technique [0002] Sewage treatment (sewage treatment, wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] At present, there are many methods for treating sewage, which can be generally classified into physical methods, chemical methods and biological methods. The principle of chemical method is to use other chemicals to react with harmful substances in sewage, so as to achieve the purpose of removing harmful substances in sewage. At present,...
