摘要
用活性炭纤维(ACF)代替传统生物活性炭法(BAC)中的颗粒活性炭(GAC),探索生物活性炭纤维(BACF)的水处理技术。首先考察了活性炭纤维的自然挂膜性能,肯定了ACF的可挂膜性。而后采用两种人工挂膜:活性污泥上清液(SL)挂膜和菌液(ML)挂膜,得到两种BACF:SL-BACF和ML-BACF。用扫描电镜研究微生物在ACF上生长情况,并采用形成的BACF处理微污染原水。结果表明:BACF去除有机污染物效果好,明显优于BAC技术。出水高锰酸盐法化学需氧量(CODMn)指标符合国家饮用水标准,水质稳定。比较两种人工挂膜形成的BACF,发现ML-BACF中的微生物量少于SL-BACF,但出水效果和处理量则优于SL-BACF。
A water treatment technique using biological activated carbon fiber （BACF） instead of granular activated carbon （GAC） was studied. First, the possibility of microbe immobilization on ACF was confirmed by means of raw water flowing through the ACF column. The microbe growth on ACF was investigated by SEM. Then, sludge liquor （SL） incubation and microbe liquor （ML） incubation were used to plant microbes on BACF to form SL-BACF and ML-BACF. The resultant BACFs were subjected to standard water treatment testing for raw water containing small amounts of pollutants. The ability of the BACF process for organic pollutant removal was better than that of BAC. The remaining chemical oxygen demand in the outflow meets the Chinese sanitary standard for drinking water quality. Comparing the two BACFs, it was found that ML-BACF was superior to SL- BACF in terms of treatment efficiency and flow capacity, although the amount of microbes immobilized on the former was less than that of the latter.
