Reuse Water Constant Pressure Toilet Flushing System in Highway Service Areas
Sewage recycling and reuse can effectively address the sewage discharge path in highway service areas.Under the premise that sewage's water production and water quality meet the demand for toilet flushing in the service area,this paper proposed a reuse water constant pressure toilet flushing system based on PLC control technology and optimized and designed the system's water volume and water pressure control.The automatic water replenishment was realized through the linkage between the frequency conversion control box and liquid level meter to accurately control the water volume in the buffer tank.The frequency conversion technology based on PLC control was used to adjust the pressure in the outlet pipe to ensure the stable operation of the toilet flushing water supply system.
