Abstract:

ACF with specific fiber structure and higher surface area tended to fix microbe more easily, which has been observed by SEM. PVA adsorption ACF and immobilization microbe technology are therefore presented. The optimal conditions for the preparation of carbon fiber biologic beads are found to be 1:20 of m(ACF):m(PVA), 20% of PVA concentration, 12 h for cross-linked time and 1:1 of m(activated sludge):m(PVA). Compared to activated carbon fiber, biological activated carbon and biological activated carbon fiber, the efficiency of carbon fiber biologic beads for phenol removal is the best, reaching more than 90%. This is a new method for the treatment of high phenol-containing wastewater.

Key words: immobilization microbe technology, activated carbon fiber, phenol

摘要：

通过扫描电镜观察到活性炭纤维（ACF）特殊的纤维结构及其高比表面积使其更易于微生物的固着、挂膜，从而提出了聚乙烯醇（PVA）包埋活性炭纤维（ACF）与微生物固定化技术。通过正交设计优化了制备炭纤维生物小球的工艺条件，其中m（ACF）：m（PVA）=12：0（包炭量）、PVA质量分数为20%、交联时间为12 h、m（污泥）：m（PVA）=11：（包泥量）。与活性炭纤维、生物活性炭及生物活性炭纤维相比，炭纤维生物小球处理高浓度模拟含酚废水效果最佳，去除率达到了90%以上。为处理高浓度含酚废水开辟了一条新途径。
