基于厌氧氨氧化与反硝化耦合的新型低碳污水处理工艺优化研究OA

In view of the problems such as low NO3--N removal rate and poor nitrogen removal efficiency of the existing methods,the optimization of a new low-carbon wastewater treatment process based on the coupling of anaerobic ammonium oxidation and denitrification adopts a spatial segmented coupling strategy,and through the proportional-integral-differential(PID)control algorithm and spatio-temporal gradient aeration control method,the dynamic regulation model integrating multi-dimensional data realizes the multi-parameter coordinated regulation of temperature,carbon-nitrogen ratio(C/N)and dissolved oxygen(DO)concentration.The results show that the NO3--N removal rate of the experimental group within the same time period is 94.3%,enhancing the regulatory effect on the nitrogen transformation process.The DO concentration in the experimental group is within the range of 0.00 mg/L to 0.29 mg/L,and the denitrification efficiency is relatively high,which enhanced the overall efficiency of sewage treatment.
