Filtration device for septic tank

Abstract

The invention relates to a filtration device for a septic tank. The filtration device comprises a barrel body, wherein a barrel cover is arranged on the barrel body, a water inlet is formed in the bottom of the barrel body, an overflow port is formed in the upper part of the barrel body, a rotating shaft is arranged in the middle of the barrel body, a plurality of filter elements are fixed on the rotating shaft, a plurality of water outlet holes are formed in each filter element, the filter elements are located below the overflow port, six filter elements are arranged in the barrel body, and accordingly, the filtration device has a good purification effect; the filter elements are located below the overflow port, filtration can be performed through the water outlet holes formed in the filter elements, and large pollutants are prevented from moving upwards; when the water level moves to the overflow port, the filtered water flows out of the overflow port, the filtration effect is realized, the barrel cover and the filter elements are taken out of the barrel body conveniently when the filter elements are required to be cleared or maintained, and the filtration device is easy and convenient to use.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a filtering device for septic tanks. Background technique [0002] At present, most of the septic tanks used in urban and rural areas are generally three-compartment septic tanks, which are generally composed of storage rooms, filter rooms and clarification rooms. They are generally separated by partitions between the various treatment rooms. A through hole is opened on the partition plate, and domestic sewage and the like reach each treatment chamber through the through hole on the partition plate of the treatment chamber, and then undergo fermentation, filtration and sedimentation to carry out sewage treatment. This type of septic tank occupies a large area, it is inconvenient to disassemble the partition, and it is cumbersome to clean and maintain. In addition, the existing septic tank has at most two-stage filtration, so that when the sewage enters the clarification chamber throu...

Problems solved by technology

This type of septic tank occupies a large area, it is inconvenient to disassemble the partition, and it is cumbersome to clean and maintain. Moreover, the existing septic tank has at most two-stage filtration, so that when the sewage enters the clarification chamber through the through hole, the large debris In addition, when cleaning, if there are many partitions, each treatment room needs to be opened separately Manual cleaning can only be done if there is a large partition, which is time-consuming and labor-intensive, the labor intensity of the workers is high, and it is extremely inconvenient to use
