Research on Response Strategies for Oxygen Corrosion in Wastewater Treatment Processes of Thermal Power Plants

在火电厂废水处理过程中,特别是在曝气池和滤池处理环节容易出现氧腐蚀问题,导致设备损坏和效率下降。基于此,研究火电厂废水处理过程中的氧腐蚀问题,并探索缓蚀阻垢剂的用量,提高废水处理系统的处理效率和使用寿命。分析了共聚物缓蚀阻垢剂的制备过程,并进行性能测试实验,验证其缓蚀阻垢效果。结果表明,该缓蚀阻垢剂配方在实验条件下表现出了良好的缓蚀性能和阻垢性能,且旋转挂片法实验和碳酸钙沉积法实验结果均符合规范要求。

In the wastewater treatment process of thermal power plants,especially in the aeration tank and filter treatment process,oxygen corrosion problems are prone to occur,leading to equipment damage and reduced efficiency.Based on this,the oxygen corrosion problem in the wastewater treatment process of thermal power plants is studied,and the dosage of corrosion and scale inhibitors is explored to improve the treatment efficiency and service life of the wastewater treatment system.This paper analyzed the preparation process of copolymer corrosion and scale inhibitors,and conducted performance testing experiments to verify their corrosion and scale inhibition effects.The results showed that the corrosion and scale inhibitor formula exhibited good corrosion and scale inhibition performance under experimental conditions,and the results of the rotary hanging method experiment and the calcium carbonate deposition method experiment both met the standard requirements.
