Study on Construction of Two-stage AO Series Process and Operation of Wastewater Treatment

本研究围绕两段AO(Anoxic-Oxic)串联工艺的构建及其在污水处理中的应用展开,深入探讨了该工艺对COD(化学需氧量)、总氮、氨氮等关键污染物的去除效果。通过实时监测反应器内DO(溶解氧浓度)、ORP(氧化还原电位)和pH值等关键参数,本研究分析了微生物的生存环境和系统反应状态,揭示了工艺的运行特性。实验结果表明,两段AO串联工艺对污染物具有显著的去除效果,出水水质稳定且满足国家一级A标准。本研究为污水处理领域提供了新的技术参考,对提升污水处理效率和水质标准具有重要意义。

This study focuses on the construction of a two-stage AO(Anoxic-Oxic)tandem process and its application in sewage treatment,and discusses the removal effect of the process on key pollutants such as COD(chemical oxygen demand),total nitrogen,and ammonia nitrogen.By monitoring key parameters such as DO(dissolved oxygen concentration),ORP(redox potential)and pH value in the reactor in real time,the living environment and system reaction status of microorganisms were analyzed,and the operating characteristics of the process were revealed.The experimental results show that the two-stage AO tandem process has a significant removal effect on pollutants,and the effluent quality is stable and meets the national first-class A standard.This study provides a new technical reference for the field of sewage treatment,and is of great significance for improving the efficiency and water quality standards of sewage treatment.
