1. Experimental purpose:
The bio-rotor is a device that uses biofilm to purify sewage. It is a biological treatment technology with good purification effect and low energy consumption. Usually, in addition to the bio-rotor, the bio-rotor treatment system also needs to include a primary sedimentation tank and a secondary sedimentation tank. This model only has a bio-rotor, and does not include a secondary sedimentation tank for separating and shedding biofilm. The m*n components are a rotating shaft, a turntable, a wastewater treatment tank and a drive device. This experimental device is both a demonstration device for the internal structure of the bio-rotor and an experimental device for treating sewage by the bio-rotor method. Through the experiment, we hope to achieve the following goals:
1. Through direct observation of the plexiglass device, deepen the understanding of its structure and understand the names and functions of each part;
2. Through the dynamic operation of the experimental device, master the technology of treating sewage by the bio-rotor method and understand the characteristics of this method.
