during sludge anaerobic digestion start-up in large-scale wastewater treatment plants and the experience in improving sludge cultivation efficiency were summarized.

The process and experience of domesticating the activated sludge are introduced,which can provide reference for commissioning similar large-scale wastewater treatment plant.

MSBR is the modified SBR technique and owing to its advantages such as compact flow, flexible control, simple unit operation and small footprint, it is quite fit to be applied into the design of small sewage treatment plant.
