1. Ensure that the water inflow is consistent with the pumping capacity. If the water inflow is greater than the pumping capacity, and the upstream does not take overflow measures in time, it may flood the grid room, or even make the sewer return water in the lower urban area. Otherwise, if the water inflow is less than the pumping capacity, it may make the pump in the dry operation state and damage the equipment.
2. Keep the high water level of the sump running, so as to reduce the pump head, high efficiency and energy consumption on the premise of pumping capacity.
3. The start and stop times of industrial sewage treatment equipment shall not be too frequent, otherwise the motor will be damaged and the service life will be reduced.
4. The operation times and time of each sewage treatment equipment in the industrial sewage treatment equipment should be basically uniform, because the water intake of each sewage treatment equipment corresponds to a part of the volume in the water collecting pool.
