AI Technical Summary
Existing two-way flow constructed wetland systems are structurally complex, cumbersome to operate and manage, difficult to operate stably in the cold climate of Northwest China, and prone to clogging.
The constructed wetland system adopts a bidirectional flow alternating vertical flow operation with anti-clogging and anti-freezing features inlet and outlet water outlets at both ends of the wetland pool. The water distribution network is arranged in a "王" shape. Combined with a PLC control system and flow meter, it achieves intelligent and uniform distribution of hydraulic load. In winter, water is distributed at the bottom and discharged at the top, while in summer, water is distributed at the top and discharged at the bottom, forming a natural backwashing mechanism.
Stable operation of wetland systems in the cold climate of Northwest China has been achieved, clogging has been prevented, the structure has been simplified, manual management has been reduced, and the temperature of the substrate layer has been maintained by utilizing the temperature of the tailwater, thereby improving treatment efficiency and system stability.
