上流式厌氧污泥床系统

Upflow Anaerobic Sludge Blanket (UASB) system

A high-rate anaerobic wastewater treatment process where wastewater flows upward through a blanket of granular sludge, retaining biomass and promoting hydrolysis, acidogenesis, acetogenesis, and methanogenesis. / 一种高效厌氧废水处理工艺，废水向上流经颗粒污泥床层，截留生物量并促进水解、酸化、产乙酸和产甲烷过程。
