Abstract: 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.

Key words: Fusarium, crude toxin, Cucumis melo, continuous cropping obstacle, allelopathic effect.
