摘要
以序批式活性污泥反应器(SBR)为主体,研究了富勒烯C_(60)水悬液的短期处理对活性污泥生化特性和微生物种群结构的影响.加入C_(60)水悬液后污泥耗氧速率变化经过迅速上升、短暂平稳、急速下降、缓慢下降、稳定五个阶段,处理6 h后C_(60)水悬液对污泥耗氧速率无显著影响;试验组与对照组污泥对氨氮的去除率均为95. 5%,对总有机碳的去除率分别为67. 7%和66. 7%; C_(60)水悬液短期内对活性污泥氨氮去除、总有机碳降解均无显著影响,PCR-DGGE结果表明,C_(60)水悬液的加入在短期内没有引起活性污泥微生物种群结构的改变.
The effects of short-term treatment of fullerene C60 aqueous suspension on biochemical characteristics and microbial population structure of activated sludge were studied in a Sequendng Batch Reacter (SBR). After adding C60 water suspension, the change of oxygen consumption rate of sludge went through five stages: rapid rise, short-term stablility, rapid decline, slow decline and stability. No significant effect of C 60 water suspension on oxygen consumption rate of sludge was observed after 6 hours of treatment. The removal rate of ammonia nitrogen in the test group and the control group was 95.5%, and the removal rate of total organic carbon was 67.7% and 66.7%, respectively. C60 aqueous suspension had no significant effect on ammonia nitrogen removal and total organic carbon degradation of activated sludge in the short term. PCR-DGGE results showed that the addition of C60 aqueous suspension did not cause the change of microbial population structure of activated sludge in a short period of time.
