Abstract ：
Antibiotic resistance genes (ARGs) as emerging contaminants, often co-occur with mobile genetic elements (MGEs) and are prevalent in drinking water treatment plants (DWTPs). In this study, the characteristics of freeliving (FL) and particle-associated (PA) ARGs associated with bacterial communities were investigated along two processes within a full-scale DWTP. A total of 13 ARGs and two MGEs were detected. FL-ARGs with diverse subtypes and PA-ARGs with high abundances displayed significantly different structures. PA-MGEs showed a strong positive correlation with PA-ARGs. Chlorine dioxide disinfection achieved 1.47-log reduction of FL-MGEs in process A and 0.24-log reduction of PA-MGEs in process B. Notably, PA-fraction virtually disappeared after treatment, while blaTEM, sul2, mexE, mexF and IntI1 of FL-fraction remained in the finished water. Moreover, Acinetobacter lwoffii (0.04 % - 45.58 %) and Acinetobacter schindleri (0.00 % - 18.54 %) dominated the 16 pathogens, which were more abundant in FL than PA bacterial communities. PA bacteria exhibited a more complex structure with more keystone species than FL bacteria. MGEs contributed 20.23 % and 19.31 % to the changes of FL-ARGs and PA-ARGs respectively, and water quality was a key driver (21.73 %) for PA-ARGs variation. This study provides novel insights into microbial risk control associated with size-fractionated ARGs in drinking water.

Abstract ：
The effect of combined antibiotics exposure on nitrogen removal, microbial community as-sembly and proliferation of antibiotics resistance genes (ARGs) is a hotspot in activated sludge system. However, it is unclear that how the historical antibiotic stress affects the subsequent responses of microbes and ARGs to combined antibiotics. In this study, the ef-fects of combined sulfamethoxazole (SMX) and trimethoprim (TMP) pollution on activated sludge under legacy of SMX or TMP stress with different doses (0.005-30 mg/L) were inves-tigated to clarify antibiotic legacy effects. Nitrification activity was inhibited under higher level of combined exposure but a high total nitrogen removal (-70%) occurred. Based on the full-scale classification, the legacy effect of past antibiotic stress had a marked effect on community composition of conditionally abundant taxa (CAT) and conditionally rare or abundant taxa (CRAT). Rare taxa (RT) were the keystone taxa in the microbial network, and the responses of hub genera were also affected by the legacy of antibiotic stress. Nitrifying bacteria and genes were inhibited by the antibiotics and aerobic denitrifying bacteria (Pseu-domonas, Thaurea and Hydrogenophaga) were enriched under legacy of high dose, as were the key denitrifying genes (napA, nirK and norB). Furthermore, the occurrences and co-selection relationship of 94 ARGs were affected by legacy effect. While, some shared hosts (eg., Cit-robacter) and hub ARGs (eg., mdtD, mdtE and acrD) were identified. Overall, antibiotic legacy could affect responses of activated sludge to combined antibiotic and the legacy effect was stronger at higher exposure levels.

Abstract ：
Rainwater recycling is a hot issue in recent years, but polypropylene (PP) module as a new type of rainwater storage facility has not received extensive attention. This study investigated the impact of rainwater pollution level, storage time (ST) and operation mode (alternate replenishment of rainwater and reclaimed water) on the pollutants removal performance and bacterial community characteristics of PP module. Chemical oxygen de-mand (COD) removal efficiency increased from 24.58%-26.52% to 33.23%-42.23% with prolonged ST. Oper-ation mode changed the purification performance, but the COD removal efficiencies in rainwater and reclaimed water were always above 28% and 42%, respectively. Operation mode exhibited the greatest impact on bacterial community structure, followed by rainwater quality and ST. The bacterial community classification in biofilm was different from that in water, but Klebsiella was always the dominant genus. Conditionally rare and abundant taxa (CRAT) and conditionally rare taxa (CRT) were identified as the hub taxa of biofilm-network and water -network, respectively. The potential pathogens in biofilm exhibited more complex interactions with non-pathogenic taxa than those in water. Klebsiella pneumoniae was the most dominant species and identified as the hub potential pathogen together with Escherichia coli in both networks. Bacterial communities in biofilm and water were significantly correlated with COD removal efficiency. These results elucidate the biological function and risk of PP module, and provide a reference for the optimization and operation management of the rainwater reuse system.

Abstract ：
Effect of copper (Cu) on antibiotic resistance genes (ARGs) and bacterial/archaeal community of activated sludge under gradient increasing (0.5-10 mg/L) or decreasing exposure (10-0.5 mg/L) modes was explored. Here, 29 genes were detected among 48 selected ARGs and mobile gene elements (MGEs). Two exposure modes showed dissimilar effects on ARGs and distribution was more affected by environmental concentrations of Cu, which promoted transmission of ARGs (multiple drug resistance and sulfonamide). Cellular protection was main resistance mechanism, which was less inhibited than efflux pumps. The tnpA-02, as main MGE, interacted closely with ARGs (sul2, floR, etc.). Gradient increasing exposure mode had more effects on bacterial/archaeal structure and composition. Bacteria were main hosts for specific ARGs and tnpA-02, while archaea carried multiple ARGs (cmx(A), adeA, etc.), and bacteria (24.24 %) contributed more to changes of ARGs than archaea (19.29 %). This study clarified the impacts of Cu on the proliferation and transmission of ARGs.

Abstract ：
This study aimed to explore the impacts of ciprofloxacin (CIP, 0.05-40 mg/L) and copper (3 mg/L) combined pollution on nitrification, microbial community and antibiotic resistance genes (ARGs) in activated sludge system during stress-and post-effect periods. Higher CIP concentration inhibited nitrification and an average of 50% total nitrogen removal occurred under 40 mg/L of CIP pressure. The stress-and post-effects on bacterial diversity and structure were obviously distinct. Abundant genera were more sensitive to combined pollution than rare genera based on full-scale classification and conditionally rare or abundant taxa were keystone taxa in their interactions. Ammonia oxidation genes were inhibited under high CIP level, but some aerobic denitrifying bacteria (Thauera, Comamonas and Azoarcus) and key genes increased. 96 ARG subtypes were detected with complex positive relationships and their potential hosts (abundant-rare-functional genera) changed in two periods. This study highlights the different stress-and post-effects of combined pollution on activated sludge.

Abstract ：
The membrane fouling triggered by biofouling layer is the critical factor limiting the application of biofiltration-facilitated gravity-driven membrane (GDM) system in decentralized drinking water treatment. Powdered acti-vated carbon (PAC) and alumina (AA) were used to mitigate membrane fouling by pre-deposition. Pre-deposited PAC and AA improved the stable flux of the biofiltration-facilitated GDM systems, increasing by 9.6% and 17.0%, respectively. The removal of dissolved organic carbon, UV254 and protein-like material was sequentially enhanced by pre-deposition of PAC and AA, respectively. Pre-deposited AA performed better than pre-deposition of PAC in restricting the adhesion of soluble microbial products to the membrane. After pre-deposition of PAC and AA, the porosities of the biofouling layers increased by 0.78% and 2.51%, and the protein/polysaccharide ratio in extracellular polymeric substances (EPS) decreased from 111.8% to 53.4% and 39.8%, respectively. The protein in tightly bound EPS showed a significant positive (p < 0.05) relationship with the total membrane resistance and genus Acidovorax. Zoogloea was the core genus among the bacterial communities related to EPS production. Overall, pre-deposition of PAC and AA can be a simple and effective strategy to alleviate membrane fouling in biofiltration-facilitated GDM.
