摘要 利用动态膜生物反应器处理生活污水,对反应器中动态膜的结构和作用进行了研究.结果表明,出水水头为8 cm的条件下,100 min以后出水水质趋于稳定,动态膜基本形成.稳定运行状态下,动态膜生物反应器对COD、氨氮和总氮的总平均去除率分别为78.4%、95.0%、40.0%,其中动态膜对COD、氨氮和总氮的平均去除率分别为19.0%、8.5%、6.0%.动态膜生物反应器对污染物质的去除主要依靠混合液活性污泥,而附着在膜基材上的动态膜的生物降解作用也能去除小部分污染物质.微生物活性分析表明,混合污泥的比耗氧速率约为动态膜比耗氧速率的5倍,混合污泥的生物活性远高于动态膜.扫描电镜分析表明,生物动态膜主要由丝状菌、杆菌、球菌及其分泌物组成. Pollutauts removal performance in dynamic membrane bio-reaetor(DMBR) treating sewage wastewater was studied. The results showed that dynamic membrane could be formed in 1(30 minutes at the head drop of 8cm. The average COD, NH3-N and total nitrogen removal rates of the reactor were 78.4% ,95.0% and 40.0% respectively. The average COD, NH3 -N and total nitrogen removal rates of the dynamic membrane are 19.0% ,8.5% and 6.0% respectively. Pollutants were mainly removed by mixed activated sludge in the dynamic membrane bio-reaetor and dynamic membrane could remove partial pollutants by biodegradation of microorganism attached on the membrane. The specific oxygen consumption rate of mixed sludge was 5 times more than that of dynamic membrane. SEM pictures showed that dynamic membrane was mainly composed of filamentous bacteria, coccus, bacillus and their excretion.
