| 中文摘要 |
| 采用中试规模(10t/d)的厌氧-好氧膜生物反应器(A/O MBR)处理毛纺印染废水.当HRT为7h,进水COD、BOD5分别为179～358mg/L和44.8～206mg/L,试验系统对COD、BODs、色度、浊度的平均去除率分别为92.1%、98.4%、60.7%、98.9%,出水水质浓度或指标值分别为20.2mg/L、1.6mg/L、25倍、0.51 NTU.出水水质指标达到建设部生活杂用水水质标准(CJ25.1-89).A/O MBR工艺处理毛纺印染废水技术可行、操作简单、易于管理,可为工业规模应用提供技术参考. |
| 英文摘要 |
| A pilot-scale (10t/d) anaerobic/oxic membrane bioreactor (A/O MBR) was used for treatment of dying wastewater from a woolen mill. The results showed that when COD, BOD5 and color in the influent was 179～358mg/L, 44 8～206mg/L and 50～240 dilution times (DT), the average COD, BOD5 and color of A/O MBR effluent was 20.2mg/L, 1.6mg/L, 25 DT respectively The removal of COD, BOD5, color, turbidity was 92.1%, 98.4%, 60.7% and 98.9% respectively. Each quota of the treated water met the gray water standards (CJ25.1-89). The A/O MBR process has many advantages, such as stable performance, simple operation, easy management etc. The result of this work could be reference for the designing of industrial scale A/O MBR process for treatment of the woolen mill wastewater. |
