Study on Rapid Start-Up Technology Of Hydrolysis Acidification Process

Abstract Domestic sewage treatment plant is an important environmental unit in the city. The hydrolysis acidification process after the overhaul of the sewage treatment plant usually had a more than three-month’s slow started-up and run unstable, seriously affecting the daily operation and also existing big environmental risks. This paper mainly expounds the factors affecting rapid start-up such as the type of inoculating sludge, the amount of sludge, the hydraulic conditions and the bacteria start-up agent for hydrolytic acidifying bacteria. The start-up speed and operation effects of hydrolysis acidification process were improved by adjusting process parameters.
