Training device of biological turntable principles

Biological turntable is a device that uses biofilm to purify sewage. It is a biological treatment technology with good purification effect and low energy consumption. In addition to the biological turntable in the biological turntable treatment system, it also needs to include the first sedimentation tank and the secondary sedimentation tank. This model is only a biological turntable, and does not include the secondary sedimentation tank of separation and falling biofilm. The m--n components are rotor shafts, turntables, wastewater treatment grooves and drivers. This experimental device is a demonstration device in the internal structure of the biological turntable, and it is also an experimental device for the sewage to treat sewage. Through experiments, I hope to achieve the following purpose:

1. Through direct observation of organic glass devices, 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 technique of processing sewage in biological turntable methods, and understand the characteristics of the method.
