Problems solved by technology

[0003] The traditional biological turntable has the problems of limited shaft length (0.5-7 meters), limited disc radius (generally 2-3 meters), biofilm blockage at the shaft and large footprint
The invention is a "pontoon-type biological drum", which not only solves the problem of the limited length of the rotating shaft, but also solves the problem that aging biofilms near the rotating shaft are difficult to fall off and difficult to renew; when used in some occasions, it also solves the problem of occupying a relatively large area. Big shortcoming, its technical scheme is elaborated as follows

Embodiment Construction

[0027] 1) Specific embodiment one.

[0028] Such as figure 1 and figure 2 , the water inlet of a lake with large flow and low concentration sewage is transformed into an existing river channel as an oxidation tank 3, and the bottom of the oxidation tank 3 is equipped with a bidirectional mud discharge device 8 with a hollow shaft, the middle part is provided with 12 fulcrums of sliding bearings, and the two ends are provided with sprockets 5 and chains 6 and mud discharge pipe 13; the shaft buoy 1 of the three-axis three-stage aerobic biological drum process is 18 meters long in total, and is composed of three 6-meter-long modules connected by bolts 9; the drum with a diameter of 2 meters uses fiber except for the buoy The (rope)-shaped lightweight filler 2 is filled, each of which is fixed on the biological drum through the filler fixing hole 10 on the bracket 4; after pretreatment, the sewage enters the oxidation tank 3 radially, and the two ends of the oxidation tank 3 ar...

Abstract

A float type biological rotating cylinder is composed of a float 1, a lightweight filler 2, an oxidation tank 3, a support 4, sprocket wheels 5, a chain 6, a decelerator 7, a mud discharge device 8 and a power motor, and can be widely used in aerobic treatment, anaerobic treatment and facultative treatment technologies. A float type rotating shaft is adopted to make the simply supported beam structure of an original common biological rotating disc or biological rotating cylinder become a floating structure or a suspending structure with the gravity being slightly greater than buoyancy, so the middle portion of the rotating shaft almost bears no bending moment, thereby the 7m length restriction of the general single shaft of the biological rotating disc or biological rotating cylinder is canceled, and the length of the single shaft is greatly expanded. The expansion of the single shaft length makes a biological rotating disc or biological rotating cylinder technology well adapt to engineering demands, and can completely overcome disadvantage of large land occupation of the biological rotating disc and biological rotating cylinder technology in some special use occasions. A bearing originally bearing the weight of a machine body almost has no bearing now, so the power consumption of the motor is reduced, thereby the technology saves more energy.

Description

technical field [0001] The invention is an innovative invention of a biological turntable for treatment equipment in the sewage treatment industry. Background technique [0002] Biological turntable is a kind of treatment equipment that uses biofilm to purify sewage. At present, it has been used to treat domestic sewage and various industrial sewage at home and abroad, and has achieved good results. Most of the final stage of the turntable has nitrification, and it also has a good removal effect on nitrogen and phosphorus. The biological turntable is mainly composed of a disk body, an oxidation tank, a rotating shaft and a driving device. The rotating shaft generally adopts solid steel shaft or seamless steel pipe. The length of the rotating shaft should generally be controlled between 0.5-7 meters. The rotating shaft should not be too long, otherwise it will be easily deformed, worn out or twisted off. The advantages of the biological turntable are good treatment effect...
