Summary: Improving nitrogen-removal efficiency is a challenging task for municipal wastewater treatment plants (WWTPs) in China due to the carbon limitation of low C/N wastewater. This study established a partial nitrification/anammox (PN/A) system to treat low C/N wastewater with insufficient carbon sources using the anaerobic-anoxic-aerobic (A(2)/O) process. The effects of dissolved oxygen (DO) concentration and internal reflux ratio on nitrogen-removal efficiency and pathway were investigated. The results showed that under optimal DO and internal reflux ratio, the PN/A system achieved highly efficient NH4+-N and TN removal rates. The study also identified the key microbes involved in anammox. This study suggests that the A(2)/O process with PN/A can be a practical engineering application for advanced nitrogen removal in low C/N wastewater.

Summary: The discharge of personal care products (PPCPs) to sewer systems has increased due to urban expansion, while the transformation of PPCPs in sewer systems and their potential threats to receiving water environments have been rarely explored. This study investigated the effect of PPCPs transformation in a pilot sewer system by continuously adding six PPCPs over a 90-day experimental period. The results showed that under PPCPs stress conditions, the biological metabolism of carbon, nitrogen, and phosphorous pollutants was restricted. Genomic detection confirmed that the diversity of microflora in sewer sediment significantly decreased with PPCPs transformation, and the relative abundance of dominant phylum species increased. In addition, the study found that two types of antibiotics were the main inducements for metabolic dysfunction in sewer systems, leading to the increase of functional genes associated with human diseases and the formation of more harmful metabolites. This investigation provides insights into the metabolic hazards of PPCPs bioconversions in sewers and highlights the importance of addressing PPCPs emission to sewers.

Summary: A novel nucleation-induced crystallization process (NICP) is proposed for the simultaneous removal of organics and hardness ions in industrial effluents. The pre-dosed seed provides reaction sites for the lattice ions, inducing Ca2+/Mg2+ ions to adhere to the seed surface. Organics attach to the seed surface through coprecipitation and surface complexation. Hydraulic regulation accelerates crystal growth and increases nucleating pellet size. The multi-stage NICP improves removal efficiency, with the 3rd-stage achieving 65.63% removal rate for total hardness and 42.95% removal rate for chemical oxygen demand (COD).

Summary: In-sewer physio-biochemical processes cause variations in wastewater quality during conveyance, affecting the influent to wastewater treatment plant and microbial community in biological treatment units. Contaminants in sewer deposits can be released during combined sewer overflows, posing challenges to treatment facilities and urban water quality. Studies have shown that biochemical reactions are organized in deposits and sewage, following redox potential and degradation sequence. Future research should focus on topics such as FOG deposits, transport of contaminants in sewer atmosphere, nonconventional contaminants, and wastewater quality variation during biofilm rehabilitation.

Summary: The pre-ozonation coagulation process has a limited range of ozone dosages for effective removal of dissolved organic matter (DOC) due to the risk of over-oxidation. In contrast, the hybrid ozonation-coagulation (HOC) process not only inhibits over-oxidation, but also improves DOC removal efficiency at a wider range of ozone dosages and different initial pH conditions. The HOC process also outperforms pre-ozonation coagulation in terms of DOC removal efficiency.

Summary: This study designs NiO nanospheres with hollow multi-shelled structure as a nanoreactor for the activation of peroxydisulfate to improve decomposition efficiency. The 3-shelled NiO HoMS exhibits enhanced kinetic rate (0.08 min-1) and mineralization degree (79.2%) compared to the 2-shelled NiO HoMS (0.04 min-1, 50%) and NiO nanoparticles (0.01 min-1, 29.8%) for the degradation of bis-phenol A. The hollow multi-shelled structure increases the accessibility of oxygen vacancy and enriches the local concentration of reactants, contributing to the enhanced catalytic efficiency.

Summary: This study demonstrated that organics modified by ozonation can be captured in real time by micro-bubble flocs mediated by the interaction among ozone, Al species, and other organics using the hybrid ozonation-coagulation process. The real-time capture strategy during the HOC process can increase organics removal efficiency and broaden the ozone dosing range. The formation of Al-organic complexes with C-O-Al coordination bonds protects the modified organics from further oxidation by ozone.
