摘 要: 采用浸没式厌氧膜生物反应器(anaerobic submerged membrane bioreactor, AnMBR)对造纸工业废水进行实验。实验启动阶段,总化学需氧量(chemical oxygen demand,COD)的去除率从初期的80%提高到90%以上,物理截留与生物作用对于水体净化的贡献得到了量化阐述,其中,膜组件的贡献从初期的57%下降到10%左右。与此同时,探讨了污泥的变化特性,灰分从7.0%增加到了35.5%,产甲烷活性(specific methanogenic activity, SMA)也显著下降。针对这一现象,从反应器特性、水质特性及操作特性3个方面阐述了可能的原因。

Abstract: An anaerobic submerged membrane bioreactor (AnMBR) was adopted for experimenting paper-making wastewater treatment. During start-up, the removal rate of chemical oxygen demand (COD) increased from 80% to 90%. Meanwhile, the two main water clean mechanisms, membrane retention and biodegradation, were evaluated by specific data. 57% of COD removed by membrane retention way in the beginning of the reaction decreased to about 10%. Moreover, the change characteristics of sludge were also monitored. In the process, the ash content was accumulated from 7.0% to 35.5%, and the specific methanogenic activity (SMA) was also decreased to a low value. Aiming at this phenomenon, three possible aspects were discussed in this paper, including reactor characteristics, water quality characteristics and operation characteristics.
