中文摘要 |
通过产酸脱硫反应器的动态试验和配套的静态试验,考察致变因子 COD/SO42-比制约的乙酸型顶极群落的结构、优势种群的组成和生态演替的规律; 阐明乙酸型代谢和乙酸型顶极群落是产酸脱硫生态系统的典型特征;揭示乙酸型顶极群落内平衡与反馈调节的生理代谢机制,并以因变因子**pH值、氧化还原电位和碱度来表征生态演替过程中优势种群的三维实现生态位. |
英文摘要 |
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. |
