水厂臭氧发生与投加系统运行维护分析
|
摘要
以Z水厂深度处理工艺中臭氧发生与投加系统为例,详细介绍臭氧发生系统稳定运行的基本要求,对水厂臭氧系统中的几大子系统(臭氧发生器本体、氮气投加系统、冷却水系统、臭氧投加系统和尾气破坏系统)在运行过程中的常见问题进行分析,认为通过日常管理和必要的专业检查、维护和保养可以降低设备运行时的故障率,达到延长臭氧系统寿命,提高运行效能的目的。
The ozone generation and dosing system in advanced treatment process in waterworks Z was taken as an example to elaborate the basic requirements for the stable operation of ozone generation system. Common problems in the operation of several major subsystems of the ozone system were summarized and analyzed,including the ozone generator,nitrogen dosing system,cooling water system,ozone dosing system and off-gas ozone destructor. For the purpose of extending the life of the ozone system and increase its operating efficiency,measures including strengthening daily management,necessary professional inspection and maintenance were put forward to reduce the failure rate of equipment operation.
