A/O MBR处理实际印染废水的实验研究
摘要
将缺氧/好氧(A/O)工艺与聚偏氟乙烯(PVDF)中空纤维超滤膜组合成为一体式膜生物反应器
并应用于印染废水处理.对该工艺的最佳工况进行了研究
试验结果表明:水力停留时间(HydraulicRetention Time
HRT)为30 h
曝气量在0.56
0
.8 m3/h(DO在3.0
5
.0 mg/L)之间
pH为8.0左右
水温控制为25℃左右的工艺运行条件是比较高效的.在此工艺条件下
用该装置对印染废水进行处理
出水水质优异
优于《纺织染整工业水污染物排放标准》(GB4287-92)一级标准.
Abstract
Anoxic/Oxic(A/O) process and Polyvinylidene Fluoride (PVDF) hollow fiber membrane filtration were combined to be a MBR(Membrane Bioreactor) used for the treatment of dyestuff wastewater.The optimum operation condition was investigated.The results showed that it was high efficiency when HRT(Hydraulic Retention Time) was 30 h
aeration rate was 0.56
0
.8 m3/h(dissolved oxygen was 3.0
5
.0 mg/L)
pH was about 8.0
and water temperature was controlled about 25 ℃.Operated under this condition
the quality of effluent is excellent and better than that of the 1st standard of Pollutants Discharging Standard of Dyestuff Industry.
