水动生物转盘处理城市污水工程中微生物生态系统结构与功能的研究

Structure and Function of Microbial Ecosystem in Wastewater Treated by Water Driven Rotary Dishes.

1 前言利用生物转盘处理污水。始于本世纪50年代。是由原联邦德国Stuttgar工科大学研制成功的一种处理污水的有效方法。它是利用微生物生态学原理,充分发挥微生物类群的净化功能。利用微生物的吸附性能形成稳定的生物膜,既耐污染负荷的冲击,又易于除去污水中的有机物。吸附和沉淀悬浮物,使城市污水得以处理,达到允许排放的标准。

The structure and function of microbial ecosystem in wastewater treated by water driven rotary dishes were studied. The results denoted that the structure of this eeosystem was a complex of microorganisms, including bacteria, fungi and actinomyces. The bacteria was a major component in the system. It possessed the deversity of the microorganism. The predominant microorganisms were preserved on the biological membrane of the biorotary dishes. The predominant groups of bacteria were belong to Bacillus, Arthrobaeter, Pseudomonas etc. Which had stronger purification ability to wastewater. When wastewater treated by water driven rotary dishes, the quality of draining off water basically reached the promised standard for industrial wastewater.
