Abstract

The invention discloses a biological rotating disc-type sewage treatment device. The biological rotating disc-type sewage treatment device comprises a contact reaction tank (1), a rotating shaft (2) is arranged in the contact reaction tank (1), two ends of the rotating shaft (2) are connected with a side wall of the contact reaction tank (1) in a rotation mode; several biological disc bodies (3) are arranged on the rotating shaft (2), a biological filling material is arranged on the external surface of the biological disc bodies (3); a sewage inlet pipe (5) and a sewage outlet pipe (6) are arranged in the contact reaction tank (1), the sewage inlet pipe (5) and the sewage outlet pipe (6) are respectively arranged at two sides of the biological disc bodies (3) and enable parallel arrangement with the rotating shaft (2), and the end parts of the sewage inlet pipe (5) and the sewage outlet pipe (6) pass through the side wall of the contact reaction tank (1). The biological rotating disc-type sewage treatment device can overcome the disadvantages in the prior art, and has reasonable and novel structural design.

Description

technical field [0001] The invention relates to a biological turntable sewage treatment device, which belongs to the field of sewage treatment. Background technique [0002] The biological turntable process is a kind of biofilm sewage biological treatment technology, which is the artificial enhancement of sewage irrigation and land treatment. Growth and breeding, the formation of film-like biological sludge --- biofilm. After primary treatment in the sedimentation tank, the sewage is in contact with the biofilm, and the microorganisms on the biofilm absorb the organic pollutants in the sewage as nutrients to purify the sewage. When the biological turntable is rotating, the surface of the disk is in contact with waste water and air alternately. The surface of the disk is covered by a film formed by the growth of microorganisms. The biofilm is fully in contact with the waste water and air alternately, continuously obtains pollutants and oxygen, and purifies the waste water. ...
