Problems solved by technology

[0002] In the prior art, sand filtration is used to filter sewage. After the equipment has been in operation for a period of time, solid particles will accumulate in the filtering mechanism. At this time, it is necessary to backwash the place to remove the accumulated solid particles. However, if backwashing is to be carried out, it must be shut down, the sewage treatment process will be interrupted, and an additional backwashing pool needs to be built, equipped with the equipment required for the air-water combined backwashing system
It can be seen that such existing sewage treatment methods have the problems of high downtime cost, low treatment efficiency, and large equipment footprint

Embodiment Construction

[0032] The turntable microprocessor of the present invention can be used, for example, in advanced treatment of municipal sewage and reuse of reclaimed water, treatment of industrial waste water, treatment of reclaimed water in fish ponds, pretreatment before ultraviolet disinfection, and the like.

[0033] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. like figure 1 and figure 2As shown, the rotary disc microfilter (also referred to as microfilter sometimes below) 100 of the present embodiment has a drum 1, which is supported on the microfilter supporting shell (not shown in the figure) and can rotate . When performing filtration treatment, the drum 1 is connected to a water inlet component (not shown in the figure), so that the water to be treated flows into the filter cavity formed by the filter mechanism 2 described below through the inside of the drum 1 . A plurality of filter mechanisms 2 are install...

Abstract

The invention mainly aims to provide a turntable type micro filter for saving the downtime cost, improving the sewage treatment efficiency and reducing the floor space. In order to fulfill the purposes, the turntable type micro filter comprises a roller (1) capable of being driven to rotate, at least one filter mechanism (2) arranged on the roller (1) and concentric with the roller (1), an elongated slot (3) formed in the roller (1), a backwashing mechanism (4), and a backwashing drive mechanism (5) for driving the backwashing mechanism (4) to swing; the filter mechanism (2) comprises a pair of filter discs (21) arranged in parallel on the roller (1), the filter discs (21) are arranged on the roller (1) through a bracket, and the pair of filter discs (21) share one bracket; the peripheral edges of the pair of filter discs (21) are sealed by a top cover plate; and the roller wall of the roller (1) between the pair of filter discs (21) is provided with an opening (11).

Description

technical field [0001] The invention relates to a microfilter for treating sewage, in particular to a turntable microfilter with a backwashing mechanism for flushing filter discs, and the turntable microfilter can run continuously without stopping for backwashing . Background technique [0002] In the prior art, sand filtration is used to filter sewage. After the equipment has been in operation for a period of time, solid particles will accumulate in the filtering mechanism. At this time, it is necessary to backwash the place to remove the accumulated solid particles. However, if backwashing is to be carried out, it must be shut down, the sewage treatment process is interrupted, and an additional backwashing pool is required to be equipped with the equipment required for the combined air-water backwashing system. It can be seen that such an existing sewage treatment method has the problems of high downtime cost, low treatment efficiency, and large equipment footprint. Con...
