Summary: This study investigated the molecular composition and transformation of dissolved organic matters (DOMs) recovered from anaerobic digestion sludge (ADS) through a mild-temperature alkali-hydrothermal treatment (AHT) and evaluated their fertilizing effects on rice growth. The results showed that AHT processes promoted the solubilization and release of DOMs from ADS, which mainly consisted of N-containing compounds with aromatic or N-heterocyclic rings. AHT processes at different pH values induced the hydrolysis and decomposition of protein-like and heterocyclic-N substances in DOMs, as well as the degradation and removal of phytotoxic oxygenated aromatic substances. Rice hydroponic test confirmed that ADS-derived DOMs recovered by AHT process at pH of 12 exhibited the highest bioactivity for rice growth, attributed to the abundance of amino compounds and humic substances. This study provides a novel process for recovering high-quality liquid organic fertilizer from ADS, enriching the technical options for the safe utilization of sludge resources.

Summary: This study assessed the possibility of anaerobic co-digestion of oil scum and secondary sludge with food waste or swine manure. It was found that oil scum with high total petroleum hydrocarbons (TPHs) content is not suitable for co-digestion, while co-digestion of secondary sludge with food waste and/or swine manure can increase methane production.

Summary: The study focuses on the use of cationic surfactant hexadecyl trimethyl ammonium bromide and co-surfactant octadecylamine to improve the stability of Pickering emulsions and arrange micron-sized silica particles at the toluene-water interface through electrostatic interaction. Organosilane reagents are also added to construct asymmetric hydrophilic or hydrophobic mesoporous onto the silica particles surface. The cation surfactant-assisted Pickering emulsion method is simple and effective, making it applicable for the synthesis of dual Janus silica particles for specific applications.

Summary: Food waste is a major component of municipal solid waste and its sustainable management is a global challenge. Co-treatment of food waste and urban wastewater in wastewater treatment plants can reduce landfill disposal while converting organic waste into biogas. However, this co-treatment can increase capital and operating costs due to the higher sludge production. This study analyzed different scenarios for co-treatment of food waste and wastewater from economic and environmental perspectives, and found that its feasibility depends on the ratio of management costs between municipal solid waste and sewage sludge.

Summary: By comparing the effects of high and low concentration ozone on partial ozonation of returned sludge, it was found that high concentration ozone can more effectively reduce organic matter and excess sludge production, with stronger nutrient removal capacity. While there were no significant differences in the treatment properties of excess sludge, the advantages of high concentration ozone mainly lie in the sludge solubilization rate and impact on carbon source utilization capacity in bioreactors.

Summary: This study investigated the recovery, survivability, and sorption of four virus surrogates in sewage sludge, leading to the discovery of different elution methods and recovery rates for each virus. The role of the solid fraction of sludge in virus inactivation was also found to be significant. Additionally, the analysis of amino acid sequences revealed that certain viruses could remain viable at lower temperatures, posing an infection risk. These findings contribute to our understanding of the environmental behavior of viruses in sewage sludge and provide a theoretical basis for risk assessment in sludge treatment and disposal.
