Biological rotary table device for treating surface water

Abstract

The invention discloses a biological rotary table device for treating surface water. The biological rotary table device comprises a plurality of biological table sheets, a rotary shaft, a floating body, a connection fixed bolt, a runner and a fallen biological film collection device, wherein the biological table sheets are distributed in parallel and are fixedly arranged on the rotary shaft by a sleeve; all the table sheets can rotate synchronously along with the rotary shaft; the floating body is used for bearing the biological table sheets and enabling the biological table sheets to float on the water; the two ends of the rotary shaft are connected with the floating body and can rotate freely. Two circular holes are formed in the opposite corners of the floating body; a fixed rod penetrates through the circular holes to fix the floating body in a water body; when two biological rotary table devices are connected, a bulge and a groove at the two ends of the rotary shaft need to be aligned with each other; the runner is fixed at one end of the rotary shaft and is used for connecting an externally-arranged power device; the fallen biological film collection device is mounted below the table sheets. The biological rotary table device for treating the surface water is strong in mobility and can meet the requirements of treating various types of the surface water; a filler ball is introduced to combine the principle of a fluidized bed with a biological rotary table so that microorganisms can attach and grow well, a treatment effect is good and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of surface water treatment equipment, and in particular relates to a biological turntable device suitable for operating in seriously polluted ponds or water areas. Background technique [0002] The biological turntable is a sewage biological treatment technology pioneered in the former Federal Republic of Germany in the 1960s. my country has introduced biological turntable counting since the early 1970s, and has carried out extensive scientific research on it. It has been applied not only in domestic sewage and urban sewage treatment, but also in chemical fiber, petrochemical, printing and dyeing, tanning, papermaking, gas generation stations, etc. It has also been applied in the field of industrial wastewater treatment in the industry and achieved good results. [0003] There are various forms of biological turntables, but its principle is mainly to rely on the metabolism of microorganisms attached to the discs to re...
