Wind blowing sewage purification device

Abstract

The invention relates to a wind-blowing-type sewage purification device, relates to the technical field of sewage treatment, and mainly aims to solve the technical problems that in the prior art, dueto the arrangement of the spray head on the downstream side of a fan, the pressure of permeation of sewage from an ultrafiltration membrane is reduced and the sewage filtering effect is affected. Theinvention adopts the main technical scheme as follows: the wind-blowing-type sewage purification device comprises a first shell tube, a second shell tube, an ultrafiltration membrane, a wind-blowing device and a spray head connected with a sewage inlet pipe, wherein the wind-blowing device comprises a wheel disc and a plurality of fan blades; the wheel disc is cylindrical and rotatably arranged inside the first shell tube; the spray head is arranged inside the wheel disc; the plurality of fan blades are circumferentially arranged on the inner wall of the wheel disc and around the spray head; gaps are formed between the fan blades and the spray head; the first shell tube comprises a first shell plate forming own inner wall; the first shell plate is a vibrating plate and is positioned on thedownstream side of the wind-blowing device; the spray head faces the first shell plate, so that water sprayed out by the spray head hits the first shell plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a wind-blown sewage purification device. Background technique [0002] As a new water treatment technology, ultrafiltration membrane filtration can effectively remove particulate matter in water, reduce water turbidity, and remove macromolecular organic pollutants, almost 100% intercept two insects, water fleas, bloodworms, algae, bacteria Even microorganisms such as viruses. Moreover, the ultrafiltration membrane filtration device can be operated at normal temperature without phase change. [0003] Ultrafiltration membrane filtration is to apply high pressure to the sewage to force the clean water in the sewage to pass through the ultrafiltration membrane, while the impurities in the sewage do not pass through the ultrafiltration membrane to purify the sewage. At present, the high pressure is mainly applied to the sewage through the fan, and the nozzle is arranged on ...
