During the start-up process, the solids of sewage sludge accumulated continuously in ASBR and kept longer solid retentiontime (SRT), helpful to enhance the treatment efficiency.
启动过程中污泥固体物质在ASBR中不断积累而保持较高的固体停留时间(SRT)，有助于提高处理效率。

The hydrolysis reactor has the advantages of having shorter hydraulic retentiontime and higher suspended solids removing efficiency because only hydrolysis and acidification stages take place.
