AI Technical Summary
When traditional purification units face the instantaneous high hydraulic load caused by heavy rainfall in the hilly areas of the south, the internal flow field generates overflow shear force, which causes biofilm peeling. Furthermore, during the dry season when the flow is scarce, the water flow dynamics weaken, leading to an imbalance in the ecosystem. Existing improvement strategies increase infrastructure costs and are inconvenient to maintain.
By setting up stepped energy dissipation embankments, overflow weirs, and ecological buffer zones, a multi-level interconnected water purification system is constructed. The purification path is spontaneously adjusted by water level fluctuations, realizing real-time coupling between the topology of the treatment unit and the dynamic hydraulic load, thus ensuring the stability and efficiency of the biochemical reaction process.
Under fluctuating water levels, the system automatically adjusts the purification path to maintain the effectiveness of the biochemical reaction, prevent biofilm stripping, improve purification efficiency and system stability over all time, and reduce infrastructure costs.
