Nowadays, saline wastewater is regarded as a challenge to wastewater treatment plants, in which high salinity shows an unfavorable effect on the conventional biological technology. Aerobic granular sludge (AGS) has attracted interests as a promising technologies for saline wastewater treatment because of its compact structure and the ability to withstand toxic loadings. Therefore, this study investigated salt-tolerance performance and mechanisms of AGS under low-salinity and high-salinity conditions that the saline concentration ranged from 0 to 50 gNaCl/L. The results showed that AGS could withstand long-term saline stresses, and the maximum salinity reached 50 g/L within 113 d. Under 10 g/L, 30 g/L and 50 g/L salinity, COD removal were 90.3%, 88.0% and 78.0% respectively, which suggests effective organic matter removal could reach in aerobic granular system. AGS remained relatively high bioactivity under 10 g/L and 30 g/L salinity. AGS also maintained strength and aggregation under 10 g/L and 30 g/L salinity. The integrity coefficients (IC) maintained 96.2% and 97.7%. The relative hydrophobicity (RH) remained 80.5% and 83.8% at the same time. The salt-tolerance mechanisms should be ascribed to overproduction of extracellular polymeric substances (EPS) by non-halophilic bacteria that enhanced sludge aggregation. And the compact structure that ensure the microorganisms bioactivity within AGS maintained the function of removing organic matters under 10 g/L and 30 g/L salinity. Under 50 g/L salinity, major shift of microbial community happened. Moderately halophilic bacteria, including Salinicola, Thioclava , Idiomarina and Albirhodobacter , prevailed in the reactor. The salt-tolerance mechanisms under 50 g/L saline condition were that the dominated microbial communities shifted to moderately halophilic bacteria, which could maintain aerobic granular stabilization and organic matters removal. These results provide further insight into the application of AGS for saline

The oxidation pathways of SO2conversion to sulfate remain controversial. Sulfur isotope (δ34S) has been used to trace the SO42–formation pathways based on sulfur fractionation. Accurately assessing δ34S fractionation is crucial to quantify SO42–formation pathways. However, previous studies have used particle-phase δ34S to estimate δ34S fractionation (α34Sg→p-estimated) in SO42–formation, leading to significant uncertainties. δ34S values of gas-to-particle (δ34SO2and δ34SO42–) were synchronously measured to uncover isotope fractionation (α34Sg→p). Results found that α34Sg→p(−3.7‰ to +9.9‰) obtained by gas-to-particle δ34S showed a significant difference with α34Sg→p-estimated(−6.4‰ to +1.4‰) obtained by δ34SO42–, implying different results for SO42–formation using the two methods. Among them, α34Sg→presults indicated the prominent pathway of NO2oxidation (48–56%), while α34Sg→p-estimated suggested the dominant role of transition metal ion (TMI)-catalyzed O2(54–80%). Additionally, α34Sg→presults show a more reasonable response to SO42–formation and consistent trends with oxidant concentrations. α34Sg→p-estimated overestimated the TMI-catalyzed O2pathway contribution (38–47%) to SO42–formation. This is the first study to employ gas-to-particle δ34S to demonstrate the dominant role of NO2oxidation in SO42–formation. This approach provides new insight into using δ34SO42–for the analysis of SO42–formation.

The excessive dissemination of New Delhi metallo-β-lactamase-1 (NDM-1), mediating the resistance to majority clinical β-lactam antibiotics, has been a major public health problem worldwide. Here, a blaNDM-1-carrying (plasmid encoded) super-resistant bacterium, named Acinetobacter sp. CS-2, was selected to reveal the mechanism of inactivation and photoreactivation during UV, chlorination and UV/chlorination disinfection. The inactivated CS-2 underwent certain photoreactivation after UV and chlorination. The logistic model precisely fitted the data obtained in photoreactivation experiments by UV treatment, with the estimated kinetic parameters: Sm (0.530%-12.071%) and k2 (0.0009-0.0471). Photoreactivation of Acinetobacter sp. CS-2 was observed when treated by chlorination at the dosage of 0.5 mg/L with the survival ratio of 34.04%. UV/chlorination not only exhibited high-efficiency reduction of CS-2, but also effectively controlled its photoreactivation with the survival ratio of 0%-0.87%. Compared with UV disinfection, UV/chlorination caused irreversible destruction of bacterial surface structures via making the cell membranes wrinkles and incomplete. Singlet oxygen (1O2) generated in UV/chlorination treatment played a vital role for ARGs removal. UV/chlorination process showed good removal efficiency at various water matrices (e.g., Cl-, Br- and drinking water). This study proposed new insights of the mechanism of inactivation and photoreactivation for the super-resistant bacteria by UV, chlorination and UV/chlorination. © 2022, The Authors.

environmental antibiotics raise serious health concerns due to their contribution to the obesity prevalence. Moreover, antibiotics promote antibiotic resistance bacteria (ARB) which represent another emerging pollutant. However, the interaction between antibiotic and ARB in the obesogenic effects remained unexplored. In the present study, the obesogenic effects of tetracycline antibiotic (TCH) and ARB containing tetA were studied on C. elegans, and E. coli OP50 (OP50) was referred as a normal bacterial food. Results showed that TCH stimulated nematode triglyceride contents, while ARB alone had no significant influences. The combination of TCH and ARB showed less obesogenic effects than TCH alone, showing antagonism. Biochemical assays showed that the combination of TCH and ARB showed similar effects to ARB alone, and had less increases in lipid metabolism enzymes or metabolites than those of TCH or ARB alone, supporting the antagonism. In the nontargeted metabolomic analysis, TCH with ARB showed less significantly changed metabolites (SCMs) in the nematodes than TCH or ARB alone, partially explaining the antagonism. The metabolomic results also pointed out the significant involvement of amino acids, the carboxylic acids and derivatives, and also the benzene and substituted derivatives in the obesogenic effects of TCH and ARB. © 2022, The Authors.

Persulfates activation by carbonaceous materials is a kind of emerging nonradical oxidation system for organic pollutants. However, the specific activation mechanisms including active sites, intermediates, and pathways have not been unveiled due to the heterogeneous of carbonaceous materials. We prepared a N,O-doped carbocatalyst (NOGM) as model material to study the activation mechanism involved. A two-electron (nucleophilic-electrophilic) reaction follows a pathway involving short-lived bound PMS species or PMS-transformed surface groups would be most possible oxidation mechanism. Pre-contact of NOGM with PMS generates bound -OO- groups and causes major transformations of surface functionality identified in unprecedented detail. Results indicate that imine-type edge-N (A-1 and A’-1) would be the possible active sites and oxaziridine (neutral and charged) is possible active intermediates. Activation pathways are given. This study goes much further about the research on carbon-based persulfate oxidation systems which can provide strategy for designing new carbonaceous materials with high activation efficiency. © 2023, The Authors.

A B S T R A C TThe toxicity of decabromodiphenyl ethane (DBDPE) has received wide attention, while the effects of environmental exposure modes on its toxicity are unclear. In this study, we compared the bioaccumulation of DBDPE and biomarkers responses of earthworms (Eisenia fetida) in the one step exposure treatment (spiked soil with 100 mg kg-1 DBDPE) and repeated exposure treatment (DBDPE concentrations in soil gradually adding from 25 to 50, 75 and 100 mg kg-1). Results show that repeated exposure decreased the bioaccumulation of DBDPE by 56.13% compared to one step exposure, but resulted in more severe damages to the epidermis and intestines surface. DBDPE in the two treatments both increased ROS levels and coelomocytes’ apoptosis rates, however, only repeated exposure showed a recovery of these two biomarkers compared to the control group. After 28 days, TRIAP1, CAM, ATP-6 and NADH1 were differently regulated between the two treatments, suggesting that the exposure mode influenced the stress responses at the gene level. This study demonstrates that the exposure patterns could affect the bioavailability and biotoxicity, and diverse animal exposure experiments are necessary to forecast environmental risks of the cumulative NBFRs in the terrestrial system. © 2022, The Authors.

In light of the ongoing socio-economic development, considerable attention has been directed towards wastewater due to its detrimental impact on water quality and associated health risks. The efficiency of removing organic pollutants from municipal sewage in a modified waste cotton cloth biofilm reactor (MWCCBR) is heavily influenced by operational functions and micro-environmental conditions. This study aimed to identify the most favorable combination of conditions that would maximize organic pollutant removal efficiency in the biofilm reactor. To achieve this research goals, an orthogonal test was conducted to investigate the optimal operation parameters, including carrier filling rate, hydraulic retention time, oxygen demand, and temperature, in order to enhance the removal of contaminants. Through a series of orthogonal experiments involving various factor levels, the most effective removal efficiencies were achieved under the following conditions: hydraulic retention time (HRT) of 10 hours, dissolved oxygen (DO) level of 3.0 mg/L, temperature of 35°C, and a filling rate (FR) of 65.0%. Throughout the treatment period, while maintaining the stable operation of the biofilm reactor, effluent samples were collected to assess the concentrations of chemical oxygen demand (COD), ammonia-nitrogen (NH4+-N), and total phosphorus (TP), along with their corresponding removal efficiencies. During the stable and optimal operational phase of the modified waste cotton cloth biofilm reactor, the average removal efficiencies for COD, NH4+-N, and TP were found to be 96.5±0.3%, 82.8±6.6%, and 60.1±0.5%, respectively. The outcomes of this study have significant implications for alternative approaches to solid waste reduction, optimal bioreactor operation, the production of value-added recycled products, the provision of clean water, and the promotion of a sustainable environment. © 2024, The Authors.

High Nitrogen Addition after the Application of Sewage Sludge Compost Decreased the Bioavailability of Heavy Metals in Soil

Nitrogen (N) fertilizer is highly significant in agricultural production. chemical nitrogen fertilizer is of great significance to agricultural production. However, long-term N addition causes changes in quality indicators, such as soil organic matter (SOM), thus, affecting the absorption and accumulation of organic pollutants. Therefore, paying more attention to organic fertilizers in the development of green agriculture is necessary. However, the accumulation of heavy metals (HMs) contained in organic fertilizers (especially sewage sludge compost (SSC)) in the soil can cause environmental contamination, but how this cumulative reaction changes with the long-term N addition remains unclear. Here the SSC impact on the bioavailability of five typical HMs (Cd, Cr, Cu, Pb, and As) in the soil-plant system without and after SSC application was demonstrated through a field study in soils with different application rates of 0, 100 and 300 kg N ha −1 yr −1 , respectively. Our results showed that SSC application increased the concentration of most HMs in soil profiles and plant systems (wheat roots and grains), but the accumulation rate of HMs and most bioaccumulation values (BAC-bioaccumulation coefficient and BCF-bioconcentration factor) in plant systems were both lower in high-N addition soil than that in the low-N group. Moreover, speciation distribution results further indicated that SSC application increased the LB (liable available form, including F1-water soluble, F2-ion exchangeable, and F3-bound to carbonates) form of HMs and decreased the PB (potentially available form, including F4-humic acids and F6-fraction bound to organic matter) form of HMs in high-N addition soil, respectively. Those results suggested that HM bioavailability was larger in high-N addition soil than in low-N addition soil when applied with SSC. Overall, this study found that increasing soil N content can inhibit the bioavailability of HMs when applying SSC, providing suggestions for optimizi
