A method for treating multiple pollutants in ship exhaust scrubbing waste liquid by adding exogenous c14-hsl

Abstract

The application discloses a method for treating multiple pollutants in ship exhaust gas washing waste liquid by adding exogenous C14-HSL. In the first step, aerobic sludge is placed in a complete-mixing anaerobic stirring reactor for domestication, and the domestication of glycerol sulfite syntrophic denitrification active sludge is completed through the mode of intermittent water feeding followed by continuous water feeding; in the second step, C14-HSL is added to the complete-mixing anaerobic stirring reactor in stages, and stable microbial community composition is formed through regulation to promote the simultaneous degradation of multiple pollutants. The comprehensive treatment of ship exhaust gas denitration wastewater and ship organic wastewater has high environmental and economic benefits.
