摘要
从现阶段国内外污泥处理与处置在环境和经济方面存在的问题出发 ,阐明了研究污泥减量技术的紧迫性。根据生物处理工艺中影响剩余污泥产生的可能途径 ,将污泥减量技术分为降低细菌合成量的解偶联技术、增强微生物利用二次基质进行隐性生长的各种溶胞技术、利用食物链作用强化微型动物对细菌捕食的技术 ,介绍了各种技术的研究现状 。
Excess activated sludge produced in the biological treatment process of wastewater requires costly disposal and will induce serious environmental pollution if the treatment is not suitable. According to production principle of excess activated sludge in biological treatment process, the possible approaches for sludge reduction may be based on three aspects: uncoupling metabolism, cryptic growth enhanced through cell lysis and microfauna prey. Relevant research works were reviewed, and characteristics of each technology were compared.
