Liquamatic biological rotating disc reaction tank and biological rotating disc treating system

Abstract

The invention discloses a liquamatic biological rotating disc reaction tank, and belongs to the field of sewage treatment. The liquamatic biological rotating disc reaction tank comprises a biological rotating disc, a rotary shaft, a contact reaction groove, a jet-flow water feeder, a water feeding pipe, a sewage pump, a water-feeding adjusting valve, a water discharging groove, a water absorbing pipe and a water feeding groove, wherein the biological rotating disc is movably arranged in the contact reaction groove by a rotating shaft; baffles are arranged at the periphery of the biological rotating disc; the jet-flow water feeder is arranged in the contact reaction groove, and a water spraying port of the jet-flow water feeder faces to the baffles arranged at the periphery of the biological rotating disc; the jet-flow water feeder is connected with the sewage pump through the water feeding groove and the water-feeding adjusting valve; the sewage pump is connected with the water feeding groove by a water suctioning pipe; and the contact reaction groove is provided with the water discharging groove. The liquamatic biological rotating disc reaction tank disclosed by the invention has the advantages that by matching of the jet-flow water feeder, the water feeding pipe and the sewage pump, a jet-flow water feeding path is formed, so that the sewage can be utilized for driving the biological rotating disc to rotate; and since the water feeding pipe is provided with the water-feeding adjusting valve, the rotating speed of the biological rotating disc can be controlled by a mode of adjusting the water-feeding flow; and the energy consumption is low and the control is easy.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a hydraulically driven biological turntable reaction tank and a biological turntable treatment system. Background technique [0002] Since the biological turntable treatment system was created in Germany in the early 20th century, it has been widely used in sewage treatment due to its low energy consumption, high treatment efficiency, impact resistance and easy maintenance. There are continuous innovations in the energy saving and operation mode of the system, but at the same time there are deficiencies. Hydrodynamic biological turntable multi-stage biological sewage treatment process (patent CN 1057040A), using the sewage in the high-level water tank as power to drive the water turbine, and the water turbine drives the biological turntable, the rotation speed of the biological turntable is difficult to adjust, the rotation friction is large, and the multi-stage biological turntab...
