活性污泥工艺中污泥减量化技术研究进展

污泥减量化技术是在剩余污泥资源化基础上进一步提出的剩余污泥处置新概念;根据生物处理工艺中影响剩余污泥产生的可能途径,将污泥减量技术归纳为降低细菌合成量的解偶联技术、增强微生物进行内源呼吸代谢的溶胞技术、利用食物链作用强化微型动物对细菌捕食的技术;并对当前污泥减量化技术进行了理论分析和应用上的概述。

Sludge reduction technique in activated sludge technology

Sludge reduction technique is a new concept for disposal of residual sludge proposed based on the reutilization of residual sludge.According to production principle of residual activated sludge in biological treatment process,the possible approaches to sludge reduction may be based on three aspects: uncoupling metabolism for the decrease of bacterial complex,cell lysis technology by enhancing microbial endogenous metabolism,and micro fauna prey upon bacteria through food chain.The research progress of sludge reduction technique was discussed theoretically and practically.
