Abstract

Abstract

Hydrothermal carbonization technology is a potential technology for the resource utilization of municipal sludge. As the main product, sludge-derived hydrochar can be used as an adsorbent for wastewater treatment. However, the effects of flocculant addition in sludge dewatering on formation and adsorption characteristics of sludge-derived hydrochar are still unclear. Therefore, in this study, three typical flocculants (polyaluminum chloride, polyferric sulfate, and polyacrylamide) were added to municipal sludge and incubated at 180 ℃ for 4 h to prepare three kinds of sludge-derived hydrochar. After that, methylene blue and tetracycline were used as simulated pollutants to investigate the effects of flocculant addition on the yield and adsorption characteristics of sludge-derived hydrochar. The results showed that different flocculants could affect not only the yield but also the adsorption characteristics of sludge-derived hydrochar. In detail, the yield of hydrochar was up to 70.14% after adding polyaluminum chloride, which was significantly improved compared with 65.35% in the blank group. In terms of adsorption, when the target pollutant was tetracycline, polyferric sulfate had a great influence on the adsorption behavior of sludge-derived hydrochar, and the adsorption capacity was up to 47.89 mg/g. When the target pollutant was methylene blue, polyacrylamide had a great influence on the adsorption behavior of sludge-derived hydrochar, and the adsorption capacity reached 23.39 mg/g. This study can provide theoretical support for effective utilization of sludge-derived hydrochar.
