Super-efficient dissolved air sewage treatment equipment

Abstract

The invention discloses super-efficient dissolved air sewage treatment equipment. The equipment includes an air floatation tank, two vertical plates are symmetrically, vertically and fixedly connectedto the upper end of the air floatation tank, the two vertical plates are symmetrically penetrated by sliding rods and are connected to the horizontal direction in a sliding mode, semicircular platesare fixedly connected to opposite ends of the two sliding rods, toothed plates are fixedly connected to the corresponding ends of the two semicircular plates, two toothed plates are symmetrically arranged relative to the sliding rods, one toothed plate is connected to an incomplete gear in a meshed mode, the incomplete gear is connected to a No.1 variable frequency motor through a flat key, and afixed cylinder is fixedly connected to the lower end of the toothed plate located on the lower side. The sewage treatment equipment has the advantages that: the No.1 variable frequency motor drives arotating cylinder and other assemblies to reciprocate in the horizontal direction through the incomplete gear and the two toothed plates, and a No.2 variable frequency motor drives the rotating cylinder to rotate circumferentially through a gear set, so that nano bubbles form a spiral shape, the adsorption effect with impurities in sewage is improved in the rotating environment, and the sewage treatment efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a super-efficient dissolved air sewage treatment equipment. Background technique [0002] Sewage is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for 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. There are various methods of sewage treatment, but when dealing with suspended solids in sewage, dissolved air flotation is more widely used. [0003] The working principle of dissolved air flotation is: the air sent to the air tank by the air compressor is brought into the dissolved air tank through the jet device, and is forced to dissolve in the water under the pressure of 0.35...

AI Technical Summary

Problems solved by technology

[0004] The existing sewage treatment equipment only has one-way air outlet, and does not have the function of rotation and lateral movement. When it is treated in a large space, the degree of integration with sewage is relatively low, and the adsorption efficiency of suspended matter in air and sewage is low. Sewage treatment low efficiency
