- Abstract:
- Aiming at the control of liquid level and flow in the inlet pump room of the wastewater treatment plant (WWTP), the automatic control mode of constant liquid level and constant flow in the inlet pump room was designed, and the start and stop conditions of the inlet pump and the flow change at high/low liquid level were studied. The results show that the inlet pump can stably maintain constant flow operation at high liquid level and the inlet pump can stably maintain constant liquid level mode at low liquid level. The mode can be switched by itself between high liquid level and low liquid level, which reduces the intensity of manual labor, the impact on the biological processing unit, and also energy consumption.
