Rotating disc type bio-reactor
Technical field
The utility model relates to a kind of rotating disc type bio-reactor, belongs to technical field of sewage treatment equipment.
Background technology
Blodisc is a kind of common equipment of biomembrance process dirty water living creature processing technique, blodisc conventional is at present made up of many discs that is large diameter, lightweight, its center is fixed on the transverse axis of sewage storage tank, and can rotate slowly with axle, about 40% of disc area is immersed in the sewage of sewage storage tank, and microorganic adhesion is in disc surface.Effluent stream is when equipment aqua storage tank, and bio-disc starts to rotate, and the microorganism be attached on disc fully contacts with sewage, and microorganism for biological metabolism reaction is carried out in nutrition, thus realizes dirty water purification with the pollutent in sewage.Sewage disposal essence, wastewater purifying efficiency depends primarily on the quantity of microorganism on disc and the kind of dominant bacteria of purifying waste water.In use for some time, mud at cell body bottom deposit, can affect aeration to existing rotating disc type bio-reactor on the one hand, on the other hand TORQ is increased, equipment is run and impacts, and easily cause turning axle to rupture, reduce the work-ing life of equipment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of rotating disc type bio-reactor is provided, it can carry out back flushing to cell body, thus the mud be deposited on bottom cell body is discharged, ensure that the running of normal aeration and rotating disk, reduce the risk of turning axle fracture, improve the work-ing life of equipment.
The purpose of this utility model is achieved in that a kind of rotating disc type bio-reactor, it comprises reaction cell body, the described reaction cell body left and right sides is provided with stationary bearing, turning axle is provided with between the stationary bearing of the left and right sides, described turning axle is provided with multiple bio-disc be arranged in parallel, described turning axle one end is connected with motor, and bottom described reaction cell body, side is provided with back flushing mouth, and bottom described reaction cell body, opposite side is provided with sewage draining exit.
Described reaction cell body side is provided with air-supply duct, and be provided with aeration tube bottom described reaction cell body, described air-supply duct is connected with aeration tube.
Described reaction cell body is provided with porthole.
Compared with prior art, the utility model has following beneficial effect:
A kind of rotating disc type bio-reactor of the utility model, it can carry out back flushing to cell body, thus is discharged by the mud be deposited on bottom cell body, ensure that the running of normal aeration and rotating disk, reduces the risk of turning axle fracture, improve the work-ing life of equipment.
