Wastewater oxygen can biodegradable experimental device

Use contacting the oxidation tower (that is, the aerated biological sewage treatment device), and the water and --r intake at the bottom of the tower can make the water pollutants be mixed with the biofilms and --r in the fillers inside the tower, prompting the oxygen to move from the gas phase to the liquid phase From liquid phase to the biofilm, ensure that the microorganisms on the membrane have sufficient oxygen to decompose and metabolize the material.

Through this experiment, I hope to achieve the following goals:

1. Master the basic operation process of contacting oxidation experiments.

2. Deepen the basic processes and principles of exposure to oxidation.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 10-15L/H

3. Design in and out of water quality (reference):
