- 摘要:
- 结合上海金海水厂臭氧生物活性炭系统的调试实测数据，创新性地总结如何利用仪表监测数据判断调试工况。为保证设备运行可靠，应确保其就地无故障运行后，再进行远程操控；并应在调试前期多次核对仪表监测数据远程反馈与就地数据。观察活性炭滤池清水调节阀开启度，可有效判断单格滤池进水均匀度，并间接检查透气孔是否畅通。利用流量仪可确定水泵最低出水启动频率，并为其他非工作水泵提供安全的点动频率。利用流量仪数据还可使不同水泵组合下的炭滤池反冲洗强度保持稳定。总结了炭滤池反冲过程中单格液位的变化规律，以判断相关设备是否开启及反冲状态。记录了炭滤池反冲时水池液位仪随时间的变化情况，以计算和研究反冲洗废水池的进水过程。
- Abstract:
- Based on the test data of O3-BAC system in Shanghai Jinhai waterworks, how to use instrument monitoring data to judge commissioning conditions is summarized innovatively. In order to ensure the reliable operation of the equipment, the remote control should be carried out without the local fault; and the remote feedback and local data should be checked many times in the early stage. The inflow uniformity of single filter can be judged by observing the opening degree of valve in BAC, and by indirectly checking whether the air vent is unblocked. The minimum water pump starting frequency data can be determined by flow meters, and provide a safe inching frequency for other non-working pumps. Data of flow meters can also ensure the stability of backwashing intensity under different pump combinations. Change of liquid level in single carbon filter during the backwashing process is also summarized, to judge the state of equipment and the backwashing process. The change of level meters during backwashing is recorded to study the influent process of the backwash tanks.
