1. Experimental principle and purpose:
Domestic wastewater treatment usually requires the simultaneous removal of nitrogen and phosphorus in one process. The m*n process of this experiment includes anaerobic zone, anoxic zone and aerobic zone. Wastewater releases phosphorus and ammoniation in the anaerobic zone, denitrification in the anoxic zone, and phosphorus absorption, nitrification and BOD removal in the aerobic zone. The whole process can simultaneously degrade organic pollutants, remove nitrogen and phosphorus, so that the effluent meets the discharge standards.
Through this experiment, we hope to achieve the following goals:
1. Master the basic operation process of domestic wastewater treatment;
2. Deepen the understanding of the principle of this experiment;
3. Understand the process flow and technical parameters of the experiment, and improve students' theoretical and practical knowledge.
