Abstract ：
A novel visible photocatalysis nanomaterials Bi2O3/rGO/TiO2 (BRGT) was combined with polyethersulfone membrane (PES) and ceramic membrane (CM), respectively, to investigate the natural organic matter (NOM) removal performance, membrane fouling behavior and interfacial interactions. The results showed that NOM removal mainly by superoxide radical-dominated photocatalysis followed by membrane rejection enhancing the removal of fluorescent humic and proteins. Compared with PES, CM could more effectively retain the low molecular weight acidic intermediates and transitional or/and hydrophilic organic fractionations generated by photocatalysis. The mixture of NOM with BRGT (without photocatalysis) reduced the reversible fouling of the PES, causing an increase in the interfacial energy barrier of the fouling layer, while the opposite phenomenon was observed for CM. The photocatalysis time affected the membrane fouling, with short photocatalysis times (5 min) causing an increase in irreversible fouling. Extending the photocatalysis time, the interfacial interaction of the PES dominated by Lewis acid-base repulsive interaction gradually increased. And the gradual decreased of interfacial interaction of CM dominated by Lewis acid-base and Lifshitz-van der Waals attractive interactions reduced the possibility of reversible and irreversible fouling, respectively. This study provided a deeper mechanistic understanding for the application of a novel photocatalyst in combination with ultrafiltration.

Abstract ：
Surfactants are increasingly used in systems that come into contact with the human body, such as food, pharmaceuticals, cosmetics and personal hygiene products. Increasing attention is being devoted to the toxic effects of surfactants in various human contact formulations, as well as the removal of residual surfactants. In the presence of ozone (O-3), anion surfactants-a characteristic micro-pollutant-such as sodium dodecylbenzene sulfonate (SDBS) in greywater, can be removed using radical advanced oxidation. Herein, we report a systematic study of the SDBS degradation effect of O-3 activated by vacuum ultraviolet (VUV) irradiation and the influence of water composition on VUV/O-3, and determined the contribution of radical species. We show a synergistic effect of VUV and O-3, while VUV/O-3 reached a higher mineralization (50.37%) than that of VUV (10.63%) and O-3 (29.60%) alone. The main reactive radicals of VUV/O-3 were HO center dot. VUV/O-3 had an optimal pH of 9. The addition of SO42- had almost no effect on the degradation of SDBS by VUV/O-3, Cl- and HCO3- slightly reduced the reaction rate, and NO3- had a significant inhibition on the degradation. In total, SDBS had three isomers, with which the three degradation pathways were very comparable. Compared with SDBS, the toxicity and harmfulness of the degradation by-products of the VUV/O-3 process decreased. Additionally, VUV/O-3 could degrade synthetic anion surfactants from laundry greywater effectively. Overall, the results show the potential of VUV/O-3 in safeguarding humans from residual surfactant hazards.

Abstract ：
Pre-ozonation is often used as an effective method to assist coagulation in removing organic contaminants. In this study, a new process that combining ozone (O-3) with vacuum ultraviolet (VUV/UV) process (VUV/UV/O-3) is investigated to enhance the removal of organic matters in greywater from public buildings or household. The influence of organic characteristics (molecular weight distribution, hydrophobicity, and fluorescence) in grey water on VUV/UV/O-3 enhanced coagulation has not been fully studied. Herein, organic matters of greywater were separated and classified, and fates of organic fractions by VUV/UV/O-3 enhanced coagulation were clarified. Greywater contains tryptophan-like and tyrosine-like proteins, and terrestrially derived humic-like substances. The highest UV254, LAS, DOC and CODCr removal efficiency from greywater could reach up to 47.54%, 58.92%, 17.96% and 15.76% in VUV/UV/O-3 enhanced coagulation, respectively. The removal efficiency of tryptophanlike and tyrosine-like in filtrates of varied molecular weight ranges by VUV/UV/O-3 enhanced coagulation was 93.59%-98.13% and 89.86%-95.53%, respectively. VUV/UV/O-3 enhanced coagulation was effective for the removal of bio-polymers, humic substances and low molecular weight acid <=& nbsp;30 kDa, while it was insignificant for that of 0.22 mu m 100 kDa. Particle size of flocs increased significantly in filtrates obtained from increasing membrane pore size, indicating that macromolecular organic matter was more likely to form flocs. Finally, the VUV/UV/O-3 could improve coagulation on the removal of varied organic pollutants and improve sedimentation by changing the flaky flocs to dense ones. Therefore, the results demonstrate VUV/UV/O-3 is an effective pre oxidation method to enhance the effect of coagulation on greywater treatment.

Abstract ：
Vacuum ultraviolet/persulfate (VUV/PS) has been a prospective method for antibiotics removal, however, the enhanced degradation mechanism is still unclear. This study compared the sulfamethazine (SMT) degradation by VUV/PS and ultraviolet/persulfate (UV/PS) processes using a photoreaction system. Results showed that the SMT degradation rate and PS activation rate by VUV/PS was 1.36 times and 1.39 times those of the conventional UV/PS process under the same dosage of PS, respectively. VUV/PS also achieved a high SMT mineralization. SO4 center dot(-) and HO center dot played important roles in the degradation of SMT by both processes, while the role of center dot O-2(-) was little. SMT concentration changed the distributions of 185 nm and 254 nm photons absorbed by solution components and altered the initiated photolysis reaction. Both processes had faster degradation rates at low initial SMT concentrations and the optimum reaction condition was at solution pH of 5. The inhibited level of the SMT degradation in both processes by four anions was in the following order: NO3- > Cl- > HCO3- > SO42-. VUV/PS process was also more efficient than UV/PS for degrading environmental (200 mu g/L) and high (5 mg/L) concentration of SMT from three kinds of typical water matrices (tap, river and lake water). Finally, ten photo-products of SMT degradation by VUV (or UV) were identified, which were mainly the oxidized products of C-N, -NH2 and S-C on SMT molecules, and four degradation pathways were proposed. Overall, these findings could provide useful insights into the application of VUV/PS in efficient antibiotics removal from water.

Abstract ：
Constructed wetlands (CWs) usually exhibit limits in functional redundancy and diversity of microbial community contributing to lower performances of nutrients removal in decentralized domestic sewage treatment. To address this quandary, heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria was added in tidal flow CWs (TFCWs) developing for nitrogen (N) and phosphorus (P) removal. With addition of HN-AD bacteria, TFCWs could be setup more rapidly and obtained better removal efficiencies of 66.9%-70.1% total nitrogen (TN), and 88.2%-92.4% total phosphorus (TP) comparing with control systems (TN: 53.9%; TP: 83.9%) during stable operation. Typical-cycles variations showed that TFCWs with addition of HN-AD bacteria promoted NO3--N and NH4+-N removal respectively under hydraulic retention time (HRT) of 14 h and 8 h with slight NO2--N accumulation. Activated alumina (AA) coupled with HN-AD bacteria decreased P release and relieved its poor removal performance in CWs. Based on metagenomic taxa and functional annotation, Pseudomonas and Thauera played pivotal roles in N removal in TFCWs. Furthermore, gradient oxic environments by 8 h-HRT promoted co-occurrence of heterotrophic nitrifiers (mostly Pseudomonas stutzeri) and autotrophic nitrifiers (mostly Nitrosomonas europaea. and Nitrospira sp.) which potentially accelerated NH4+-N transformation by elevated nitrification and denitrification related genes (e.g. amoABC, hao, napA and nirS genes). Meanwhile, the addition of HN-AD bacteria stimulated nirA and gltD genes of N assimilation processes probably leading to NH4+-N directly removal. The conceptual model of multi-metabolism regulation by HN-AD process highlighted importance of glk, gap2 and PK genes in glycolysis pathway which were vital drivers to nutrients metabolism. Overall, this study provides insights into how ongoing HN-AD bacteria addition effected microbial consortia and metabolic pathways, serving theoretical basis for its engineered applications of TFCWs in decentralized domestic sewage treatment.

研究了山东地区引黄水库水水厂存在的季节性铝超标问题。结果表明,出厂水中铝主要来自进水所含及铝盐混凝剂引入,出厂水铝超标的主要原因为进水pH变化造成的混凝效果不佳导致的溶解性铝过量。当进水pH小于8.2时,现用的聚合氯化铝不会造成出厂水铝超标;当pH在8.2～8.4时,更换为铁盐混凝剂可取得较高的效果,其中聚合硫酸铁具有更佳的pH适应性;当pH大于8.4时,先降低进水pH才能取得有效的调控效果。采用聚合氯化铝铁有效地解决了水厂铝超标问题,为引黄水库水水厂出厂水的铝含量保障提供了技术支持。

Abstract ：
In-situ collection, purification and reuse of indoor greywater of public buildings or household is an effective way to save water resources. Refractory organic micropollutants in greywater, such as antibiotic sulfamethazine (SMT), can be potentially removed by sulfate radical-advanced oxidation process (SR-AOP) in the presence of peroxymonosulfate (PMS) or peroxydisulfate. Herein, vacuum ultraviolet (VUV) with irradiation at 185 nm and 254 nm activating PMS was systematically investigated in terms of degradation efficacy and influences of water constituents, and the contribution of photolysis and radical oxidative species was determined. We show that SMT removal efficiency and PMS photolysis efficiency of VUV/PMS were 2.2-fold and 1.45-fold compared to UV/PMS, respectively, and VUV/PMS reached a higher mineralization. The main active radicals of VUV/PMS were HO center dot, SO4 center dot-, and center dot O-2(-) . Compared to UV/PMS, VUV/PMS resulted in a higher proportion of oxidative degradation and a lower proportion of photolysis. Higher SMT concentrations competed for absorption of VUV or UV-generated photons with H2O and PMS molecules, resulting in a less efficient reaction. VUV/PMS was more efficient at lower initial SMT concentrations and had an optimal pH of 5. The presence of SO42- slightly accelerated degradation performance while HCO3- and NO3- inhibited both processes; the inhibitory effect of HCO3- and NO3- on VUV/ PMS are more significant than on UV/PMS. In contrast, the presence of Cl- had no significant effect on each process. In total, 13 intermediates of SMT were identified and four degradation pathways were proposed. VUV/PMS had an advantage over UV/PMS in removing the produced harmful and toxic intermediates. Furthermore, VUV/PMS could remove SMT from real water matrix more effectively than UV/PMS. Generally, the results demonstrate the potential of VUV to displace UV for more effective in-situ treatment of indoor greywater.
