- 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.
