地埋式一体化AO工艺处理锂离子电池电解液生产废水工程实例

摘要

Aiming at the characteristics of Li-ion battery electrolytes wastewater,such as complex organic components,high oil and NH+4-N,the buried integrated AO technology was used for the treatment of effluent. The results show that,when the influent COD is 2000 ~5500mg/L,oil 3300 ~8200mg/L the effluent quality can reach the third class criteria specified in Integrated Wastewater Discharge Dtandard(GB 8978-1996).%针对废水有机成分复杂,且石油及氨氮浓度比较高等特点,某公司采用选用"地埋式一体化AO工艺"的方式进行处理.运行结果表明,在进水COD浓度为2000~5500 mg/L、进水石油类浓度为3300~8200mg/L时,其出水效果显著且各项指标均达到《污水综合排放标准》(GB 8978-1996)的三级排放标准.
