Construction of the biosystem with low consumption and high efficiency of nitrogen and carbon removal and its application in teaching

Abstract

Shortcut nitrification and denitrification coupled with anaerobic ammonia oxidation process is a new biological process for the removal of nitrogen and carbon in wastewater treatment, with the advantages of low energy consumption, low sludge production, which can greatly reduce the cost of wastewater treatment. Through the designed experiment of the system and the evaluation experiment of carbon and nitrogen removal effect, which were convenient for students to understand more clearly and provided hands-on activities for students. Experiment showed that the system with the removal of nitrogen and carbon functioned well, and enhanced students’ knowledge of the process, to motivate their interests in learning professional knowledge. In the period of experiment design and literature review, the abilities of independent thinking and problem solving were improved and the enthusiasm, initiative and creativity in scientific research also got enhanced.
