During the start-up process, the solids of sewage sludge accumulated continuously in ASBR and kept longer solid retention time (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 retention time and higher suspended solids removing efficiency because only hydrolysis and acidification stages take place.
其中水解反应器因为仅发生水解和产酸反应，停留时间短，对悬浮物的去除率很高。
