微氧条件下颗粒污泥的特性及影响因素研究

Study on the Characteristic and Influencing Factors of Granular Sludge under Microaerobic Condition

微氧颗粒污泥是近几年发现的在微氧条件下形成的固定化颗粒,具有良好的沉降性能和较高的抗冲击负荷的能力。微氧技术结合了好氧和厌氧技术的优点,许多难降解物质可以在好氧菌与厌氧菌共同参与下被彻底降解。该文主要分析了微氧颗粒污泥的工作特性、形成过程以及影响污泥颗粒化的各种因素。

It is found that micro-aerobic granular sludge is a kind of fixed particle which is formed under the condition of micro-aerobic in the last few years. It has good settlement performance and higher supporting shock load capacity.The micro-aerobic skill combines the advantages of aerobic and anaerobic.A lot of refractory materials can be degraded thoroughly under the participation of aerobic and anaerobic bacteria.The work performance and formation process of the micro-aerobic granular sludge and all kinds of inffluencing factors affecting sludge granulated were analyzed in this paper.
