- 摘要:
- 在污水处理过程中，曝气系统控制的精确度和能效水平直接关系到污水处理厂的运营成本和环境效益。针对郑州市某污水处理厂的多参数联动曝气优化体系，分析了精确曝气系统的趋近循优策略与动态调整技术等应用效果，同时进行稳定性、电耗、碳减排量的评估。该系统应用后，生物池溶解氧得以稳定控制，主要出水水质指标均有下降，夏冬两季鼓风机电单耗同比分别降低10.78%和5.31%，碳减排量为2 780.5 tCO2/a。
- Abstract:
- In the wastewater treatment process, the aeration system directly impacts the operational costs and environmental benefits of a wastewater treatment plant through its control precision and energy efficiency. Focusing on a multi?parameter linked aeration optimization system implemented at a wastewater treatment plant in Zhengzhou, this study investigated the application effects of an approaching optimal strategy and dynamic adjustment technology for precise aeration systems. Simultaneous assessments were conducted on system stability, electricity consumption, and carbon reduction. The results demonstrated that the system successfully stabilized dissolved oxygen concentrations in the biological reactor, reduced key effluent quality indicators, and achieved annual reductions in specific power consumption for blowers of 10.78% and 5.31% during summer and winter seasons, respectively. The annual carbon reduction reached 2 780.5 tCO2.
