Aeration system

Abstract

The invention relates to an aeration system which comprises an aeration tank. An aerator is arranged outside the aeration tank and connected with an aeration pipeline extending into the aeration tank, the aeration pipeline comprises a plurality of wind shear aeration ends and a plurality of edgewise aeration ends, the wind shear aeration ends are uniformly arranged at the bottom end of the aeration tank, each wind shear aeration end is of a fan-shaped structure, the edgewise aeration ends are positioned at the radial circumference of the inner side wall of the aeration tank, intersected with the inner wall of the aeration tank, inclined downwards to the inner side wall of the aeration tank and extend, electric spraying nozzles are arranged at ports of the wind shear aeration ends and the edgewise aeration ends and flush with the inner wall of the aeration tank, fan-shaped spread and distributed air flow is uniformly and sufficiently distributed into the aeration tank, edge corners in the aeration tank can effectively aerate, aeration blind angles are omitted, sewage treatment efficiency is greatly improved, and sewage treatment time is shortened.

Description

technical field [0001] The invention belongs to the sewage treatment technology in the technical field of chemical industry, and in particular relates to an aeration system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage or reuse; sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields ; The chemical industry produces a large amount of sewage every year. One of the procedures in the sewage treatment process is aeration, so that the activated sludge in the sewage can obtain sufficient dissolved oxygen and then decompose harmful substances in the sewage. The existing aeration device is expensive to manufacture, and the aeration The air sent by the air machine is difficult to fully mix with the activated sludge, so the sewage treatment effect is also poor. Con...
