Sewage filtering device

Abstract

The invention discloses a sewage filtering device, which comprises a water pool body, wherein a biological rotating tube is rotationally arranged in the water pool body; a first gear disc is fixed atthe end surface of one end of the biological rotating tube; a driving motor is fixed at the outer part of the water pool body; a first rotating shaft is coaxially fixed on a rotor of the driving motor; a first worm rod is fixed on the first rotating shaft positioned in the water pool body; the first worm rod is engaged with the first gear disc; a first gear is fixed on the first rotating shaft; asecond rotating shaft is also arranged in the water pool body; a second gear is coaxially fixed on the second rotating shaft; a second worm rod is fixed on the second rotating shaft; a cleaning rollertube is rotationally arranged in the water pool body; the cleaning roller tube and the biological rotating tube are in coaxial arrangement; a second gear disc is fixed at the end surface of one end of the cleaning roller tube; the second gear disc and the second worm rod are engaged. The sewage filtering device solves the problems that a gap is left between two turntables in a biological turntable; the gap can be easily blocked by some flocculates, so that the sewage treatment effect is influenced.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage filtering device. Background technique [0002] Biological turntable is a kind of biofilm sewage treatment technology, which is developed on the basis of biological filter, also known as submerged biological filter. The process has the advantages of flexible system design, convenient installation, simple operation, reliable system, and low operating and operating costs; it does not require aeration or sludge return, which saves energy and can obtain higher The purification effect has been widely used in the treatment of various domestic sewage and industrial sewage. The turntable mechanism in the biological turntable is usually arranged at equal intervals along the length of the rotating shaft, and there is a gap between the two turntables, so that the sewage can effectively contact the end face of each turntable to improve the sewage treatment effect, but in the actual filt...
