摘要
以厌氧膨胀颗粒污泥床(EGSB)反应器处理冷轧含油废水过程中所形成的厌氧颗粒污泥的形态和微生物相为研究对象,对颗粒污泥的驯化及微生物相变化进行研究并初步鉴定污泥微生物。结果表明,接种污泥被驯化并稳定运行后,微生物较快适应反应器环境并稳定成长,颗粒污泥粒径出现渐增且有明显分层,且粒径从底部到上部逐渐减小。扫描电镜及微生物相鉴定结果主要显示以甲烷蝇菌属、鬃毛甲烷菌属、甲烷八叠球菌属3种菌属为主。
An anaerobic expanded granular sludge bed （EGSB） reactor was used to treat cold-rolling oily wastewater. The morphology of anaerobic granular sludge formed in EGSB reactor and the microbial phase was inves- tigated,the preliminary identification of microorganisms in granular sludge was also taken. The results showed that microbial adaptability was strengthening and granular sludge particle size was gradually increasing with the time run- ning;the sludge particle size of granular sludge from the Bottom to the upper was gradually reduced,and there was a significantly layered phenomenon. Base on the SEM photographs and microorganism identification,three mainly kinds of methane bacteria were found in granular sludge,they were Methanolinea spp. ,Methanosaeta spp. and Methanosarcinales spp.
