The disposal and resource utilization of sewage sludge (SS) have always been significant challenges for environmental protection. This study employed straightforward pyrolysis to prepare iron-containing sludge biochar (SBC) used as a catalyst and to recover bio-oil used as fuel energy. The results indicated that SBC-700 could effectively activate persulfate (PS) to remove 97.

- Researchers developed a composite of porous sludge biochar (PSDBC) and zero-valent iron (ZVI@PSDBC) to enhance the activation of persulfate (PS) for degrading 2,4-dichlorophenol (2,4-DCP) in wastewater.
- Both the PSDBC/PS and ZVI@PSDBC/PS systems achieved near-complete removal of 2,4-DCP within 20 minutes, with mineralization rates reaching 73.7% and 91.6% after 60 minutes, respectively.
- Characterization techniques showed that the unique structure and conductivity of the composites aided in radical production and efficient electron transfer, demonstrating their potential for effective wastewater
An efficient biosorbent containing magnetic nanoparticles, walnut shell powder, foam, and alginate (AMWSF) was prepared and used in Pb(II) removal. The adsorption process was performed in an airlift magnetic separation loop system. Optimum adsorption conditions were tested at pH 3-7, biomass dose of 0.
