Problems solved by technology

[0002] The oily sewage treatment devices and systems in the prior art need to separate the sediment and oil from the sewage at the same time, usually requiring graded filtration, the system is complex and occupies a large area; After operation, it is usually necessary to flush the filter device to restore its filtering ability; if the adaptability to sewage treatment capacity of different concentrations is poor, especially when high-concentration sewage treatment is carried out after a period of operation, the effect is not good; such sewage treatment The method leads to high comprehensive operation cost of sewage treatment

Abstract

The invention discloses a rotary filtration method for sewage. The method comprises the following steps: external force drives a rotary filter assembly to make the rotary filter assembly rotate arounda central axis perpendicular to the ground; when the sewage to be treated enters the interior of the rotary filter assembly through an outer surface, dirt is blocked at the outer surface of the rotary filter assembly; and water entering the interior of the rotating filter assembly is discharged through a first discharge opening communicating with the interior of the rotary filter assembly. A filter comprises a filter main body, the rotary filter assembly, a rotary power device, a water inlet and the first discharge opening; the rotary power device drives the rotary filter assembly for rotaryfiltration; the external sewage passes through and is filtered by the rotary filter assembly, and the dirt is blocked outside the rotary filter assembly; and the first discharge opening is arranged inthe bottom of the filter main body, runs through an inner cavity of the rotary filter assembly and is used for discharging filtered sewage. According to the method and filter disclosed by the invention, rotary filtration greatly improves filtration capacity and operation efficiency and enables oil stain to be accumulated at the upper part of the filter main body, and comprehensive efficiency of oil-water separation is greatly improved.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a filter and a filtering method for high-efficiency filtering of oily sewage. Background technique [0002] The oily sewage treatment devices and systems in the prior art need to separate the sediment and oil from the sewage at the same time, usually requiring graded filtration, the system is complex, and the floor area is large; After operation, it is usually necessary to flush the filter device to restore its filtering capacity; if the adaptability to sewage treatment capacity of different concentrations is poor, especially when high-concentration sewage treatment is carried out after a period of operation, the effect is not good; such sewage treatment The method leads to high comprehensive operation cost of sewage treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to avoid the shortcomings of the above-mentioned prior a...
