进水泵房恒液位恒流量自控系统改造效能评估
- Title:
- Efficiency Evaluation of Constant Liquid Level and Constant Flow Program Reformation in the Inlet Pump Room of WWTP
- 摘要:
- 针对某污水厂进水泵房液位和流量控制情况，设计开发了进水泵房恒液位恒流量自动控制模式，研究了在高/低液位下，进水泵的启停以及流量变化情况。结果表明，在高液位下，进水泵能够稳定保持恒流量模式运行；在低液位下，进水泵稳定保持恒液位模式运行；在高液位与低液位之间，模式可自行切换，降低了人工劳动强度及对生物处理单元的冲击，同时也降低了能耗。
- 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.
