Project Scale:

500-800m³/d

Project Introduction:

The main construction content of this project is the remediation of the Aohe County section (Wetland Park - Water Park) to ensure that the water quality reaches Grade III standards. It includes five major sub-projects: the Wetland Park-Water Park water environment improvement project (8 solar aerators), the ecological river construction project (demonstration project 50m long, 3m wide, total area 150m2, 10 solar aerators), the comprehensive treatment project of sewage outlets along the river (3 MBR integrated units, 7 integrated purification units, multi-stage biological filters), the underwater forest construction project, and the dredging project. After the implementation of this project, the total pollution load reduced to the river will be COD: 686.7 tons/year, Ammonia Nitrogen: 157.2 tons/year, Total Phosphorus: 20.9 tons/year, with a total dredging volume of approximately 150,000 cubic meters.

Our company was responsible for the comprehensive treatment project of sewage outlets along the river (3 MBR integrated units, 7 integrated purification units, multi-stage biological filters). The project commenced construction in August 2018 and was completed, accepted, and put into use in December 2019.

After implementation, the water quality of Aohe will be significantly improved, transforming from the current inferior Grade V to Grade III water quality, providing a clean water source for Le'an County and contributing to its long-term stable development.
