The Ecological Succession of Climax Community Restricted by COD/SO42- Ratio in Acidogenic Desulfate Bioreactor
产酸脱硫反应器中COD/SO42-比制约的群落生态演替规律

The ecological succession of climax community restricted by COD/SO42- ratio, the causing ecological factors, was investigated in acidogenic desulfate bioreactor with continuous flow and batch flow experiment. It was demonstrated that aceticacid type metabolization and aceticacid type climax community were the typical characteristic of acidogenic desulfate ecosystem, and the internal balance and feedback adjusting mechanism of the climax community was analyzed. In addition, threedimension realized ecological niche figure of preponderant population during the course of ecological succession was presented based on the following ecological factors of pH value, oxidation reduction potential and alkalinity.
