TL;DR: Challenges and existing problems of sludge disposal in China, including high CO2 emissions, unbalanced regional development, low stabilization and land utilization levels, were discussed and suggestions regarding potential technical and administrative measures in China and sustainable sludge management for developing countries were given.

TL;DR: This review summarizes activation methods, including physical, chemical, and other coupling approaches, for efficient generation of sulfate radicals and evaluates their applications and economic feasibility.

TL;DR: In this article, a review summarizes the performance, degradation pathways and relevant mechanisms of typical antibiotics during bismuth-based photocatalytic degradation, as well as the coupling processes for degradation enhancement.

TL;DR: Experimental results showed that S2O82- oxidation effectively disintegrated the polymeric EPS and led to a more significant reduction in the water content for HPO-WAS than for HPI-W AS, providing new insight into the enhancement of S2 O82-/Fe2+ oxidation for sludge dewatering based on polarity analysis of EPS.

TL;DR: Experimental results implied that the doping of Mg2+, Fe3+, Zn2+ and Cu2+ dramatically improved the photodegradation of Bi2WO6 for NOR and CIP removal, in which 1% Mg/Bi2 WO6 exhibited the highest degradation rate.
