| 1 | Investigation of drinking water bacterial community through high-throughput sequencing显示文摘Delivery of safe and pathogen-free drinking water is crucial to public health.However,there exist challenges to the maintenance of the sterility of drinking water throughout the drinking water distribution systems(DWDS).Microbial growth in DWDS,such as growth of opportunistic pathogenic microorganisms,can lead to severe health problems in consumers(Berry et al.,2006;Brettar and Hofle,2006;Lu et al.,2014;Zhang et al.,2015). | Tsz Wai Ng Guocheng Huang Po Keung Wong | 2015 | Journal of Environmental Sciences2015，27，11： | 5 |
| 2 | Characterization of bacterial community and iron corrosion in drinking water distribution systems with O3-biological activated carbon treatment显示文摘Bacterial community structure and iron corrosion were investigated for simulated drinking water distribution systems(DWDSs) composed of annular reactors incorporating three different treatments: ozone, biologically activated carbon and chlorination(O_3-BAC-Cl_2);ozone and chlorination(O3-Cl_2); or chlorination alone(Cl_2). The lowest corrosion rate and iron release, along with more Fe_3O_4 formation, occurred in DWDSs with O_3-BAC-Cl_2 compared to those without a BAC filter. It was verified that O_3-BAC influenced the bacterial community greatly to promote the relative advantage of nitrate-reducing bacteria(NRB)in DWDSs. Moreover, the advantaged NRB induced active Fe(III) reduction coupled to Fe(II) oxidation, enhancing Fe_3O_4 formation and inhibiting corrosion. In addition, O_3-BAC pretreatment could reduce high-molecular-weight fractions of dissolved organic carbon effectively to promote iron particle aggregation and inhibit further iron release. Our findings indicated that the O_3-BAC treatment, besides removing organic pollutants in water, was also a good approach for controlling cast iron corrosion and iron release in DWDSs. | Xueci Xing Haibo Wang Chun Hu Lizhong Liu | 2018 | Journal of Environmental Sciences2018，30，7： | 4 |

| 6 | O_3-BAC-Cl_2: A multi-barrier process controlling the regrowth of opportunistic waterborne pathogens in drinking water distribution systems显示文摘Simulated drinking water distribution system(DWDS) treated with O_3-BAC-Cl_2(ozonebiological activated carbon-chlorine) was constructed to study its effects on the regrowth of five typical opportunistic pathogens(OPs). It was found that O_3-BAC-Cl_2 could significantly reduce the regrowth of target OPs in the effluents of DWDS compared with Cl_2 and O_3-Cl_2 with the same residual chlorine levels. However, the effect of O_3-BAC-Cl_2 on the average numbers of target OPs gene markers in the biofilms of DWDS was not apparent, suggesting that OPs in the biofilms of DWDS were tolerant to the upstream disinfection process. The quantification of target OPs in the BAC-filter column demonstrated that OPs decreased with the increase of depth, which was likely due to the organic nutrient gradient and microbial competition inside the BAC-filter. Increase in the ozone dose could further reduce the OPs at the bottom of the BAC-filter. Spearman correlation analysis demonstrated that some significant correlations existed between target microorganisms, suggesting potential microbial ecological relationships. Overall, our results demonstrated that the BAC-filter may act as a 'battlefield'suppressing the OPs through microbial competition. O_3-BAC-Cl_2 could be an effective multibarrier process to suppress the proliferation of OPs in the bulk water of DWDS. However, OPs protected by the biofilms of DWDS should receive further attention because OPs may be detached and released from the biofilms. | Lizhong Liu Xueci Xing Chun Hu Haibo Wang | 2019 | Journal of Environmental Sciences2019，31，2： | 1 |

| 8 | 饮用水管网生物膜中弧菌数量影响因素研究显示文摘研究饮用水管网中管材、管龄、管径等因素对生物膜弧菌数量的影响。采集中国东部某市管网生物膜样本12份,用硫代硫酸盐-柠檬酸盐-胆盐-蔗糖琼脂培养基分离培养弧菌,并用弧菌科细菌生化鉴定系统鉴定并计数。结果表明,弧菌检出率为50%(6/12)。在管龄相近的不同管材管壁生物膜中,弧菌数量为球墨铸铁管(212±39.40CFU/cm^2)>镀锌钢管(4.85±1.03CFU/cm^2)>不锈钢复合管(0.66±0.21CFU/cm^2),并且球墨铸铁管中的弧菌数量与其他管材间差异有统计学意义(P<0.05),而在塑料管中未检出弧菌;而不同管龄的球墨铸铁管以及镀锌钢管生物膜中弧菌数量变化不明显;在不同管径(公称直径为200、150和300mm)的球墨铸铁管生物膜中,弧菌数量分别为2.65×10~3±204、212±39.40和44.20±6.88CFU/cm^2。综上表明,管材对生物膜弧菌数量有较大的影响,其中,以球墨铸铁管中的弧菌数量最多;因此,饮用水管段的铺设应考虑铸铁管的潜在弧菌风险。 | 史亚 施晓峰 张永静 柳景青 程东庆 | 2016 | 浙江大学学报(农业与生命科学版)2016，42，6： | 0 |
