Micro-filter for wastewater treatment and wastewater treatment method thereof

Abstract

The invention relates to the technical field of filtering equipment, and discloses a micro-filter for wastewater treatment and a wastewater treatment method thereof. The microfilter comprises a base,a check ring is fixedly connected to the middle of the base, and supporting rollers are fixedly connected to the two sides of the middle of the base. A movable pipe is disposed and round holes are arranged in the outer end of a threaded blade, when the micro-filter carries out filtering work, the outer end of the movable pipe is connected with a negative pressure fan, negative pressure is generated in the threaded blade at the moment, impurities attached to the interior of a filter screen are sucked away through the round holes, and after the filter screen rotates for a period, the impuritiesattached to meshes of the filter screen can be completely removed, and the impurities are prevented from blocking the meshes of the filter screen, after the filtering work of the micro-filter is completed, the movable pipe body is rotated by 45 degrees and is communicated with a water pump, at the moment, water flow can flush the filter screen through the round holes formed in the outer end of thethreaded blade, after the filter screen rotates by a period, water flow sprayed out of the round holes can flush the whole filter screen, and dead corners which cannot be cleaned are avoided.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a microfilter for wastewater treatment and a wastewater treatment method thereof. Background technique [0002] The microfilter is a kind of filter that intercepts fine suspended matter. It has a drum-shaped metal frame. The sleeve bracket can rotate around the horizontal axis. The middle part of the sleeve bracket is equipped with a support net and a working net woven by stainless steel wire, which can be used for The working principle of industrial water filtration, industrial wastewater treatment, etc. is that when the aquaculture water passes through the microporous screen on the sleeve bracket of the microfiltration machine, under the rotation of the sleeve bracket, the solid waste in the aquaculture water is Separation is carried out to purify the water body and achieve the purpose of recycling. [0003] However, the existing microfilters for wastewater treatme...

AI Technical Summary

Problems solved by technology

[0003] However, the existing microfilters for wastewater treatment still have the following deficiencies in the actual use process: First, when the traditional microfilters are working, due to the low motor speed, after the solid-liquid separation of the wastewater, there will be residues on the inner surface of the filter screen. A large amount of solid impurities. Although the inner surface of the existing filter screen is equipped with deflectors, which can export the fixed impurities, the export efficiency of this method is slow, and the export efficiency is poor, and it is easy to cause more accumulation on the inner surface of the filter screen. Solid impurities not only seriously reduce the filtration efficiency of the microfilter, but also increase the burden on the filter screen, resulting in deformation and failure of the filter screen; secondly, when the filter screen filters waste water, not only solid impurities but also Some viscous impurities that are easy to adhere to, some of which are small particle impurities and water-insoluble viscous impurities will get stuck in the mesh of the filter mesh, which will cause serious blockage of the mesh of the filter mesh, which not only seriously affects the filtration efficiency of the filter mesh, but also makes it difficult to to clean up
