A PILOT SCALE EXPERIMENT ON VC-MAKING WASTEWATER TREATMENT BY MEMBRANE BIO-REACTOR

By 冯斐, 周文斌, 汤贵兰, 严滨 and 蒋林煜

Abstract

主要介绍了某维生素制造企业废水系统运行情况以及MBR改造工艺的启动方法和在不同工艺条件下的运行情况。通过比较2种工艺条件,确定污泥浓度控制在8000mg/L,溶解氧控制在2mg/L,水力停留时间14h,系统对CODCr的平均去除率能达到90·20%,氨氮的平均去除率能达到89·95%。It is maily introduced the performance of a wastewater plant of a VC-producing company and the start-up method of the VC wastewater treated by the MBR process and the running under different conditions of the system.Through comparing two different process conditions,when the sludge concentration is controlled at 8 0000 mg/L ,DO controlled at 2 mg/L and the HRT controlled at 14 hours,the average COD_ Cr removal rate will be 90.2% and the NH_3-N removal rate will be 89.95%
