Urban sewage treatment training device

Urban sewage treatment tr--ning device,Performance experimental device in water room

1. Experimental principles and purposes:

Living wastewater treatment usually needs to complete the effect of nitrogen dehydration and phosphorus and removing phosphorus and removing phosphorus and removing phosphorus in one process. The m--n process of the experiment includes anaerobic areas, hypoxic areas, and good oxygen areas. Wastewater is phosphorus release and ammonia in anaerobic areas. Nitrogen dehydration is performed in hypoxic areas. Phosphorus absorption, nitrification and nitrification and To remove BOD, the entire set of processes can also achieve the effect of degrading organic matter pollutants, nitrogen removal, and phosphorus removal, so that the output of water is discharged.

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

1. Master the basic operation process of living wastewater treatment;

2. Deepen the principle of understanding the experiment;

3. Understand the process and technical parameters of the experiment, and improve the theoretical and practical knowledge of students.
