UASB+A/O处理甜菜制糖废水工程实例

Engineering Example for Wastewater Treatment of Beet Sugar by UASB+A/O

介绍采用UASB+A/O工艺处理甜菜制糖废水的工程实例。实际运行结果表明,系统运行稳定,处理出水COD≤81 mg/L,BOD≤13 mg/L,SS≤41 mg/L,NH3-N≤7.5 mg/L,处理出水达到《制糖工业水污染物排放标准》(GB21909—2008)。工程运行费用低,环境效益和社会效益明显。

The engineering example for wastewater treatment of sugar beet by UASB+A/O is introduced.The running results show that the process has stable treatment efficiency.COD,BOD,SS and NH3-N in the treated effluent is less than or equal to 81 mg/L,13 mg/L,41 mg/L and 7.5 mg/L respectively,and the effluent quality meats the criteria in the discharge 'Sstandard of Water Pollutions for Sugar Industry'(GB21909—2008).The operating cost is low and it has obvious environmental and social benefits.
