废水厌氧生物处理中的共基质代谢和种间协同代谢作用

On the Co-Substrate and Communal Synergistic Metabolisms in Anaerobic Biological Treatment of Wastewater

分析了难降解物质在共代谢和种间协同作用下的生物降解。指出添加合适的一级基质并维持适当的一级基质浓度可使难降解物质利用速率达到最优化 ;种间协同作用对厌氧生物处理顺利进行是非常重要的 。

The biological degradation of indegradable substances under co-substrate metabolism and communal syn-ergism is discussed and indicated that addition of primary substrate and to keep it at appropriate level could speed-up the utilization of the indegradable substances. The communal synergism is very essential to the normal progress of anaerobic biological treatment process and the formation of bio-film and sludge granule is helpful to give full play to the communal synergism.
