In 2013, Veolia China partnered with Tonghua Group’s subsidiary, Anhui Liuguo Chemical Co., Ltd., to establish Tongling Liuguo Veolia Water Services Co., Ltd. Under a 20-year contract, the collaboration provides water supply and wastewater treatment services for Anhui Tongling Liuguo Chemical’s production lines, including phosphorus and ammonia-rich wastewater reuse solutions.
In March 2025, the Liuguo Veolia Wastewater Treatment Facility Upgrade Project commenced in Tongling, Anhui. To achieve dual enhancements in treatment capacity and water quality, Veolia adopted an AO Biochemical Treatment + Secondary Sedimentation Tank + High-Efficiency Settling Tank + Contact Disinfection system. This technology not only improves processing efficiency but also significantly reduces regional pollutant emissions, advancing ecological conservation and industrial green transformation. The upgraded infrastructure supports the city’s "dual carbon" strategy by providing robust environmental protection facilities.
Projections after the Project’s Upgrading and Transformation:
Daily wastewater treatment capacity: Up to 14,400 m³/day
- Annual reductions on COD: 289.06 tons, reduction on suspended solids: 157.68 tons, reduction on ammonia nitrogen: 94.6 tons, reduction on total phosphorus: 24.97 tons, reduction on total nitrogen: 81.46 tons
