Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] In the present invention, unless stated otherwise, the orientation words included in the term such as "one end, the other end" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, should not be construed as a limitation of this term.

[0034] Such as Figure 1-Figure 3 As shown: the present invention provides a biological turntable for sewage treatment. The biological turntable includes a sump 1, an aeration mechanism arranged inside the sump 1, and a plurality of good-raising turntables 12 connected in sequence. The anaerobic turntable mechanism formed by connecting the good-rais...

Abstract

The invention discloses a biological rotating disc for sewage treatment. The biological rotating disc comprises a water collecting tank, an aeration mechanism arranged inside the water collecting tank, an aerobiotic rotating disc mechanism formed by connecting multiple aerobiotic rotating discs in order, and an anaerobic rotating disc mechanism formed by connecting multiple anaerobic rotating discs in order. The aerobiotic rotating disc is a circular ring structure such that a cavity which is coaxial with the aerobiotic rotating disc mechanism is formed inside the aerobiotic rotating disc mechanism. The biological rotating disc comprises a shield shell positioned inside the cavity. The anaerobic rotating disc mechanism is positioned inside the shield shell. The shield shell positioned outside the cavity is fixed on the water collecting tank. A motor is fixed inside the shield shell. The motor is connected to a rotating shaft. The aerobiotic rotating disc mechanism and the anaerobic rotating disc mechanism are respectively coaxially fixed on the rotating shaft such that the rotating shaft can simultaneously drive the aerobiotic rotating disc mechanism and the anaerobic rotating discmechanism to coaxially rotate. The problem that an aerobiotic biomembrane outside the biological rotating disc is easy to fall off after scoured by current such that oxygen enters an internal anaerobic biomembrane and then anaerobic treatment effect becomes worse is solved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a biological turntable for sewage treatment. Background technique [0002] Rotating Biological Contactor (RBC for short) is a biofilm sewage treatment technology, pioneered by the former Federal Republic of Germany in the 1960s, developed on the basis of biological filters, also known as submerged biological filters . The process has the advantages of flexible system design, convenient installation, simple operation, reliable system, low operation and operation costs; it can obtain high purification effect in a short contact time, and has been widely used in various domestic sewage and industrial sewage treatment. The biological turntable replaces the fixed filter material with a rotating disc. When working, the turntable is immersed or partially immersed in the contact reaction tank full of sewage, driven by the driving device. The rotating shaft drives the turntable to rotate ...
