Focusing on improving water quality, daily water quality maintenance work such as water quality maintenance, water body restoration, and emergency response to sudden water quality deterioration events will be implemented to eliminate black and odorous water quality in river channels and significantly improve water quality transparency. At the same time, gradually restore the river's own ecosystem.

Adopting technology: (ecological restoration)
Non point source pollution control technology - ecological revetment, garbage removal, and standardization of wastewater discharge from livestock and poultry breeding industry
Point source pollution control technology - interception well or laying interception pipe
Internal pollution control technology - river dredging
In situ restoration technology for aquatic ecology - sediment purification+water quality purification
