Sewage treatment device and sewage treatment method applying device

Abstract

The invention relates to a sewage treatment device and belongs to the technical field of sewage treatment. The sewage treatment device comprises a tank body, wherein the tank body is internally provided with a sewage treatment cavity; the sewage treatment cavity is internally provided with a first bracket-shaped like a character L and a second bracket-shaped like a mirror image of L; a vertical aeration channel is arranged between the first bracket and the second bracket; an aeration device is arranged at the bottom of the vertical aeration channel; a bubble elimination device is arranged at the top of the vertical aeration channel; the bubble elimination device comprises a driving motor, a retractable shaft and a fan blade; a rotary surface of the fan blade is parallel to the liquid levelin the vertical aeration channel. According to the sewage treatment device provided by the invention, the bubble elimination device and an aeration device are mutually matched to use, so that the problem of blocking a pipeline through bubbles in the prior art is avoided. The invention further relates to a sewage treatment method; a step of eliminating the bubbles is increased in the sewage treatment method so that the aeration amount of the aeration device can be improved under the condition that the smoothness of the pipeline is ensured and equipment is normally operated, and the content ofdissolved oxygen in sewage is increased, and furthermore, the sewage treatment efficiency is increased.

Description

technical field [0001] The invention relates to a sewage treatment device and a sewage treatment method using the device, belonging to the technical field of sewage treatment. Background technique [0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for drainage or reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage produced in daily life, which refers to the complex mixture of various forms of inorganic and organic substances. [0003] In the prior art, whether it is production sewage or domestic sewage, its main sewage ...

Problems solved by technology

However, with the opening of the aeration system, a lot of air bubbles are generated back and forth on the liquid surface. The accumulation of these air bubbles usually leads to blockage of the pipeline in the system and affects the normal operation of the equipment.

However, if the aeration volume of the aeration system is reduced, although the generation of air bubbles can be improved, the supply of dissolved oxygen in the sewage is insufficient, resulting in poor aeration effect
