This is a smart sponge demonstration project of the Sino-German cooperation project KEYS. The overflow pollution control is carried out at the overflow end of the buried culvert of Yudai River, and the back flushing of stagnant water of the buried culvert is realized by using the water level difference between the open channel and the buried culvert.
A complete set of hydraulic driving equipment is adopted, the flat bar screen achieves interception treatment, and the gate type automatic flushing system uses the water volume of the open channel section of the Yudai River to flush and clean the hidden channel section connecting the interception pipes. For specific process introduction, please refer to Gu Hong's environmental protection paper "Application of Energy Optimization Management Methods and Technologies in Rainwater Management under the Background of Carbon Neutrality" (Proceedings of the 11th Advanced Research Conference on Rainwater Management and Black and Odor Water Treatment in China Water Supply and Drainage, 2021).
