摘要
在火力发电厂锅炉补给水处理系统中,微生物污染是威胁水质安全、导致膜污堵、树脂中毒及系统腐蚀的关键因素。针对某660MW发电厂锅炉补给水处理系统存在的问题,系统分析了微生物污染的形成机理、杀菌剂类型选择、药剂投加位置,结合该电厂锅炉补给水生产实际运行数据,提出基于水质监测与精准控制加药模式,通过采取优化措施后,对比优化前、后运行数据,结果显示:杀菌效率提升30%以上、年综合运行成本可节约35万元,为火电厂水处理系统安全经济运行提供技术支撑。
In the feedwater treatment systems of thermal power plants,microbial contamination remains a critical factor threatening water quality safety and causing membrane fouling,resin poisoning,and system corrosion.Addressing operational challenges in a 660MW power plant's boiler feed-water system,this study systematically analyzes the formation mechanisms of microbial contamination,selection of biocide types,and optimal dosing positions.Leveraging actual operational data from the plant's feedwater production,we propose a precision dosing model based on water quality monitoring.Through optimized measures,comparative analysis of pre-and post-optimization operational data reveals:biocide efficiency increased by over 30%,with annual comprehensive operating costs reduced by 350,000 yuan.These findings provide technical support for ensuring safe and cost-effec-tive operation of thermal power plant water treatment systems.
