Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] see Figure 1-Figure 4 , the bio-rotary disc of the present invention is a combination of non-woven fabric wrapping and biological carrier filler filling, including several biological bio-discs 1 and rotating shafts 6 . All bio-discs 1 are arranged in parallel, and a cylinder net 7 is arranged between two adjacent bio-discs 1, that is, there is one more bio-disc than the cylinder net, and the diameter of the cylinder net 7 matches the diameter of the bio-disc 1 , both ends of the cylindrical net 7 are fixed on the corresponding bio-disc 1 . A rotating shaft sleeve 3 passes through the center of all the bio-discs 1 and the cylindrical net 7, the rotating shaft sleeve 3 is set on the rotating shaft 6, and the rotating shaft 6 is driven to rotate by the driving device, and the rotating shaft sleeve 3 and the rotating shaft 6 are fixed with screws Can ro...

Abstract

The invention discloses a biological rotating disc in combination of non-woven fabrics package and biological carrier filler filling. The biological rotating disc comprises a plurality of biological discs, wherein cylindrical nets are arranged between every two adjacent biological discs; and the two ends of each cylindrical net are fixed on the corresponding biological disc. A rotary shaft sleeve passes through the centers of all biological discs and the cylindrical nets; and the rotary shaft passes through the rotary shaft sleeve and is fixed together with the rotary shaft sleeve and also can rotate synchronously therewith. The biological discs are made of macromolecule plastics and non-woven fabrics are covered outside the biological discs. The two ends of each cylindrical net are provided with biological membrane protection nets parallel to the biological disc corresponding to the cylindrical net; and each filler chamber is divided into three small filler chambers by three filler chamber filters. The biological disc disclosed by the invention has short membrane hanging circle; the biological discs on the disc have excellent adhesion properties; the matrix in the biological discs can be uniformly mixed; the transferring effect is excellent; and the pollutant removal performance of a reactor is improved.

Description

technical field [0001] The invention relates to a biological turntable combined with non-woven fabric wrapping and biological carrier filling, and belongs to the technical fields of environmental protection and water treatment equipment. Background technique [0002] The biological turntable was created in the Federal Republic of Germany in the 1950s and 1960s. It is an efficient sewage biological treatment technology. A traditional biological turntable is mainly composed of a biological disc, a contact reaction tank, a rotating shaft and a driving device. According to the requirements of sewage treatment, the discs of the biological turntable are fully or partially immersed in the contact reaction tank filled with sewage. Under the drive of the driving device, the rotating shaft drives the turntable to rotate at a certain speed continuously, and the discs of the biological turntable alternate In contact with waste water and air, after a period of rotation, a layer of biofi...
