针对地埋式污水处理系统的特点,将一种高浓度微生物制剂用于生物膜反应器的挂膜,研究了其在处理模拟家庭生活污水过程中的启动特性.在进水化学耗氧量、氨氮和总磷分别为750、48和7.5 mg·L?1的条件下,装置运行10 d后,对三者的去除率分别达到85%、58%和35%.光学显微镜、环境扫描电镜观察显示,随着系统的去除率逐渐升高,微生物的种类也在逐渐改变;聚合酶链式反应-变性梯度凝胶电泳的检测结果则表明,火山岩填料和悬浮填料表面生长的微生物种类较为丰富,虽然不同条件下微生物群落发生了不同程度变化,但是整个微生物系统仍保持相对的稳定性.

@@@@According to the characteristics of a buried sewage treatment system, the start-up of high concentration microbial agents in dealing with analog household sewage was studied in a biofilm reactor. When the chemical oxygen demand, ammonia nitrogen, and total phosphorus are 750, 48 and 7.5 mg·L?1, the removal rates of them are 85%, 58%, and 35% after operation for 10 d, respectively. Optical microscopy and environmental scanning electron microscopy observations show that with the system removal rate increasing, the microbial species gradually changes. The results of polymerase chain reaction-denature gradient gel electrophoresis (PCR-DGGE) demonstrate that the microbial species on volcanic rocks and suspended fillers are abundant, and the microbial community changes under different conditions, but the whole system of microorganisms maintains relatively stable.
