Novel sewage filtering device

Abstract

The invention relates to a novel sewage filtering device, which relates to the technical field of sewage treatment, and mainly aims at solving the technical problems that the existing sprayer is arranged at the downstream side of a fan, so that the seepage pressure of the sewage on an ultrafiltration membrane is reduced, and the sewage filtering effect is influenced. The novel sewage filtering device mainly is characterized in that the novel sewage filtering device comprises a first case pipe, a second case pipe, an ultrafiltration membrane, an air blowing device and a sprayer used for being connected with a sewage inlet pipe, wherein the air blowing device comprises a wheel disc and a plurality of fan blades; the wheel disc is in a round tube shape and is rotationally arranged in the first case pipe; the sprayer is arranged inside the wheel disc; the plurality of fan blades are arranged on the inner wall of the wheel disc in the circumferential direction and are arranged around the sprayer; a gap is formed between the fan blades and the sprayer; the first case pipe is provided with a first case pipe forming the self inner wall; the first case plate is a vibration plate and is positioned at the downstream side of the air blowing device; the sprayer is arranged in a way of facing the first case plate so that water sprayed out from the sprayer collides the first case plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel sewage filtering 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 the down...
