Soil dissolved organic matter (DOM) is crucial to atmospheric, terrestrial and aquatic environments as well human life. Here, by characterizing DOM from 89 grassland soils throughout China, we reveal the spatial association between geochemistry in dry season vs annual ecosystem exchange cancer cases. The humic-like high molecular weight (3.4–25 kDa) fractions with lower biodegradability, decline northern southern regions of are correlated soil respiration net productivity at continental...
Per- and polyfluoroalkyl substances (PFAS) contamination has posed a significant environmental public health challenge due to their ubiquitous nature. Adsorption emerged as promising remediation technique, yet optimizing adsorption efficiency remains complex the diverse physicochemical properties of PFAS wide range adsorbent materials. Traditional modeling approaches, such response surface methodology (RSM), struggled capture nonlinear interactions, while standalone machine learning (ML)...
This study investigates the effect of landfill age on leachate characteristics; two aspects are focused here. One is ultraviolet absorbance at 254 nm (UV(254)) property, as discharge leachates to publically owned treatment works can cause interference with UV(254) disinfection. The other biorefractory organic nitrogen in leachates, it contribute effluent making difficult meet stringent regulations. To variation UV(254)-absorbing carbon and nitrogen, samples ranging from cells ages 2 30 y a...
Abstract Partial nitritation (PN) is a novel treatment for nitrogen removal using aerobic ammonium oxidation with reduced oxygen requirements compared to conventional nitrification. This study evaluated the performance of PN process and factors influencing from landfill leachate. During reactivation biomass, results showed 70% removal, but only 20% total removal. Further analysis that low nitrite accumulation high nitrate production promoted growth nitrite‐oxidizing bacteria (NOB). The...
The discharge of municipal landfill leachate into publicly owned treatment works (POTWs) is a common management practice in the United States.
Nitrifiers in chloraminated drinking water distribution systems can trigger severe nitrification, resulting subsequent quality deteriorations. However, the occurrence and dynamics of nitrifiers secondary supply (SWSSs), an important component beyond mains, remain largely unexplored. This study investigated density, distribution, diversities different microbial habitats (water, biofilm, sediment) SWSSs with characteristics. Quantitative polymerase chain reaction analysis indicated higher gene...
IFAS process was coupled with SBR operation in a pilot-scale reactor to verify the feasibility and evaluate performance of IFAS-SBR. Significant nitrification improvement IFAS-SBR system observed, which is attributed both introduction attached-growth biomass on media carriers “seeding effect” by biofilm sloughing.
Floods have the potential to resuspend polycyclic aromatic hydrocarbons (PAHs) laden sediments and potentially impact drinking water intakes. This work identifies optimal operating conditions for PAH removal from using a combined permanganate (Mn(VII))/bisulfite advanced oxidation process (AOP). PAHs in aqueous solutions containing humic acid (HA) were treated combination of bisulfite at different molar ratios. Results showed that Mn(VII)/bisulfite AOP was an effective method remove priority...
