The nitrogen and phosphorus removal performance of denitrifying phosphorus removal bacteria in wastewater treatment under the influence of different carbon/nitrogen ratio(C/N) and other environmental factors(such as pH value, dissolved oxygen, temperature) was analyzed. From the aspects of bacterial selection and culture,simulated wastewater allocation, experimental design and data analysis, this paper aims to reveal how the carbon nitrogen ratio and the above environmental factors regulate the process of nitrogen and phosphorus removal. The optimization strategy based on experimental data and the corresponding mathematical model are proposed to predict the specific effects of different parameters on the efficiency of nitrogen and phosphorus removal. This study can improve the efficiency of wastewater treatment and reduce operating costs, and solve the problems of low efficiency of nitrogen and phosphorus removal process and unclear influence of environmental factors in the existing wastewater treatment technology. Through systematic experimental methods and detailed data analysis, it provides scientific basis and practical guidance for the design and operation optimization of sewage treatment system, and promotes the development of sewage treatment technology and the progress of environmental protection.
