- Abstract:
- Photovoltaic wastewater has characteristics of high nitrates and fluorine content. A photovoltaic wastewater treatment project in Jiangsu Province in China is a reconstruction project with the design capacity of 6 000 m3/d, and its effluent is required to meet the indirect discharge criteria in Emission Standard of Pollutants for Battery Industry (GB 30484-2013). The original process couldnot meet the discharge requirements, so the process of secondary defluorination, denitrifying granular sludge and A/O is adopted for reconstruction. The total investment is 21.5 million yuan and the operating cost is 25.2 yuan/m3, which is 20% lower than before. Since commissioning, the performance of reconstructed project is good and the effluent quality stably meets the discharge standard requirements.
