I. Necessity of Rainwater and Sewage Separation

In urban drainage systems, the mixing of rainwater and sewage can overload wastewater treatment plants and even lead to direct discharge into natural water bodies, causing pollution. Intelligent interception wells automatically switch separation modes by real-time monitoring of flow rate and water quality, ensuring that rainwater is directly discharged into rivers while sewage is sent to treatment plants. This technology not only reduces the treatment pressure but also lowers the risk of overflow pollution, which is crucial for protecting urban water ecosystems.

II. Working Principle of Intelligent Interception Wells

Sensor Monitoring: Real-time collection of data such as flow rate and turbidity to determine the type of water flow, laying a foundation for accurate separation decisions.

Automatic Gate Control: Dynamically adjust the opening and closing of gates based on monitored data to achieve precise diversion of rainwater and sewage. For example, it maintains sewage interception during sunny days and switches to rainwater direct discharge during heavy rains to prevent waterlogging.

Remote Management: Supports cloud-based monitoring, allowing operation and maintenance personnel to check real-time operating status and quickly respond to abnormal situations such as gate malfunctions or liquid level anomalies through mobile devices or computers.

III. Core Advantages Brought by the Technology

Compared with traditional interception wells, intelligent systems significantly reduce manual intervention and improve the accuracy of separation. Their adaptive capacity enables them to cope with extreme weather such as heavy rains, effectively regulating water flow to avoid urban waterlogging. In the long run, this technology can significantly reduce operation and maintenance costs-thanks to its high degree of automation and low failure rate-and play a vital role in protecting water ecological environments by minimizing pollutant discharge into natural water bodies.
