Startup Research of DIC Hydrolysis Acidification Reactor in Printing and Dyeing Wastewater Treatment

Abstract:

As the main source of textile industrial pollution, printing and dyeing wastewater is usually difficult to be biodegraded. In this paper, a unique hydrolysis acidification reactor with double circulation sludge recycling system (DIC) is designed to treat simulated printing and dyeing wastewater. The results show that DIC reactor can realize quick startup with concentrated sludge of sludge concentration tank as inoculated sludge. And DIC reactor has high removal capabilities for CODcr and chroma, with efficiencies of about 70% and 60%, respectively. The sludge concentration is obviously increased. Moreover, the biodegradability of wastewater has been greatly increased to 0.38, which is favorable to the removal of organic pollutants in wastewater.
