Biological nitrogen removal of wastewater with hydrolysis-acidification liquor of excess sludge as additional carbon source
以剩余污泥水解酸化液为外加碳源的污水生物脱氮

In order to solve the problem about the shortage of carbon source for denitrification in the biological nitrogen removal of low C/N ratio wastewater,the integrated biological aerated filter(BAF) with aeration section and non-aeration section was employed to investigate the performances and process conditions for the biological nitrogen removal of low C/N ratio wastewater when the hydrolysis-acidification liquor of excess sludge was used as additional carbon source.The experimental results showed that VFAs a...
