Abstract:
The combined process,coagulation sedimentation-UASB-A/O treatment system-secondary sedimenta-tion,has been used for treating the wafer cleaning wastewater from photovoltaic industry. The design parameter of the project,the starting processes of UASB reactor and A/O treatment system and the operation status of the treatment project are introduced. The operation results indicate that the COD and SS of the effluent are 117 mg/L and 71 mg/L, respectively,and their removing rates are 95.4% and 96.2%,respectively,meeting the requirements of the indirect discharge limit value specified in the Emission Standard of Pollutants for Battery Industry(GB 30484-2013). The process runs stably,being a kind of reliable process for treating wafer cleaning wastewater.
