The water treatment system and drainage system of a hydropower station jointly ensure the efficient, safe, and environmentally friendly operation of the power station.

Water Treatment System:

Pretreatment: Initially removes large particles from the water to prevent blockages in subsequent treatment equipment.

Purification: Uses physical, chemical, and biological methods to further purify the water, ensuring it meets the requirements for equipment operation.

Recirculated Water Treatment: Treats recirculated water to prevent corrosion and scaling of equipment, extending the service life of the equipment.

Drainage System:

Plant Drainage: Collects and removes various wastewater, seepage, and standing water within the plant to ensure the dryness of the plant interior.

Tailwater Drainage: Removes tailwater from the power station to ensure smooth discharge and prevent flooding.

Rainwater Drainage: Collects and discharges rainwater to prevent equipment damage during the rainy season.

Wastewater Treatment: Treats wastewater generated during the operation of the power station to ensure it meets discharge standards and minimizes environmental impact.

Main Equipment Components of the System:

Pumps: Used for drawing and conveying water.

Control Valves: Used to regulate water flow and pressure.

Piping and Trough Networks: Used to guide water flow.

Monitoring and Automation Components: Used for real-time monitoring and automated control.
