Bio -turntable principle experimental device

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.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 2 ～ 5L/h

3. Staying time: 3 ～ 5H,

4. Dimensions of shape: The plate is made of PVC to make φ250mm × 900mm × 300mm,

5. Design in and out of water quality range:

COD 500 ～ 1000mg/L out of water 50 ～ 100 mg/L

Enter the water 100 ~ 300mg/L out of water 30 ～ 40 mg/L

Inlet water pH 6-9 out of water 6-9

6. Device shape size: 1200mm × 400mm × 1300mm

7. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 300W power, safety protection: ground protection, leakage protection, overcurrent protection

Equipment structure:

 

The practical tr--ning model of the three -dimensional traffic lights is a metal structure. The I/O terminals of the tr--ning assessment device module, the connection terminals of each commonly used module and the connecting terminals are connected to the safe socket, and the circuit is connected with a wire with a safe plug. The circuit of the switch and the indicator element is connected through the terminal row. The combination of the plug -in connection circuit with the terminal connection circuit not only ensures the tr--ning, formation and consolidation of the basic skills of students, but also to ensure the rapid, safe and reliable circuit connection.
