1. Before starting the machine, you should first check whether there are any obstructions around the equipment, whether there are leakage points in the pipeline interfaces and valves of the advection dissolved air flotation machine equipment, whether the electrical facilities comply with safety management regulations, and whether the safety protection devices of the operating equipment are complete. , you can follow the steps only after everything is correct.
2. Dissolve, store and reserve the added drugs according to process requirements.

4. When starting up normally, you should first turn on the dissolved air system to mix and circulate air and water, adjust the pressure of the advection dissolved air flotation machine, and after balancing, turn on the sewage pump and open the dosing valve. Adjust the size of the valve according to the water volume until it reaches the water discharge standard, and then mark the two valves to prepare for the correct start-up next time.
5. Drain sewage regularly and perform backwashing until there is no sludge at the sewage outlet.
6. When shutting down, first stop the dissolved gas system, then stop the sewage pump, close the main valve of each medicine tank, and adjust the valve. Generally, there is no need to close it after adjustment. If the machine is shut down for a long time, the dirt inside and outside the tank should be removed, and each medicine tank should be washed clean.
7. Keep records of shift handovers, sum up experience in a timely manner, and improve operational levels and problem-solving abilities.
8. Do a good job in personal safety and equipment protection
