多段 AAO 污水处理厂精确曝气系统设计与调试

Summary on Design and Commissioning of Precise Aeration System for Multi-stage AAO Wastewater Treatment Plant

摘要:

为了能够更好地解决污水处理过程中经常遇到的曝气不足、出水氨氮超标，曝气过量反硝化不好导致的总氮超标、能耗浪费等问题，以深圳市某污水处理厂多段AAO处理工艺为研究对象，介绍了在生化池中引入精确曝气系统的设计和调试情况，并结合实际运行情况对精确曝气控制系统的效用进行了分析和总结。

Abstract:

In order to better solve the problems of insufficient aeration, excess ammonia nitrogen in effluent, excessive aeration and poor denitrification leading to excess total nitrogen and waste of energy consumption often encountered in the process of sewage treatment, taking the multi-stage AAO treatment process of a wastewater treatment plant in Shenzhen was as a research object, the design and commissioning of the precise aeration system introduced into the biochemical tank are described, and the effectiveness of the precise aeration control system is analyzed and summarized according to the actual operation situation.
