| 2 | Effects of ultrasonic pretreatment on sludge dewaterability and extracellular polymeric substances distribution in mesophilic anaerobic digestion显示文摘Effect of ultrasonic pretreatment on sludge dewaterability was determined and the fate of extracellular polymeric substances (EPS) matrix in mesophilic anaerobic digestion after ultrasonic pretreatment was studied. Characteristics of proteins (PN), polysaccharides (PS), excitation-emission matrix (EEM) fluorescence spectroscopy and molecular weight (MW) distribution of dissolved organic matters (DOM) in different EPS fractions were evaluated. The results showed that after ultrasonic pretreatment, the normalized capillary suction time (CST) decreased from 44.4 to 11.1 (sec·L)/g total suspended solids (TSS) during anaerobic digestion, indicating that sludge dewaterability was greatly improved. The normalized CST was significantly correlated with PN concentration (R2 = 0.92, p < 0.01) and the PN/PS ratio (R2 = 0.84, p < 0.01) in the loosely bound EPS (LB-EPS) fraction. Meanwhile, the average MW of DOM in the LB- EPS and tightly bound EPS (TB-EPS) fractions also had a good correlation with the normalized CST (R2 > 0.66, p < 0.01). According to EEM fluorescence spectroscopy, tryptophan-like substances intensities in the slime, LB-EPS and TB-EPS fractions were correlated with the normalized CST. The organic matters in the EPS matrix played an important role in influencing sludge dewaterability. | Liming Shao Guanzhao Wang Huacheng Xu Guanghui Yu Pinjing He | 2010 | Journal of Environmental Sciences2010，22，3： | 29 |

| 5 | Effect of ultrasonic pretreatment on anaerobic digestion and its sludge dewaterability显示文摘To investigate the effect of ultrasonic pretreatment on anaerobic digestion and sludge dewaterability and further to probe into the influencing factors on sludge dewaterability,sludge flocs were stratified into four fractions: (1) slime;(2) loosely bound extracellular polymeric substances (LB-EPS);(3) tightly bound EPS (TB-EPS);and (4) EPS-free pellets.The results showed that ultrasonic pretreatment increased the anaerobic digestion efficiency by 7%–8%.Anaerobic digestion without ultrasonic pretreatment deteriorated the sludge dewaterability,with the capillary suction time (CST) increased from 1.42 to 47.3 (sec·L)/g-TSS.The application of ultrasonic pretreatment firstly deteriorated the sludge dewaterability (normalized CST increased to 44.4 (sec·L)/g-TSS),while subsequent anaerobic digestion offset this effect and ultimately decreased the normalized CST to 23.2 (sec·L)/g-TSS.The dewaterability of unsonicated sludge correlated with protein (p = 0.003) and polysaccharide (p = 0.004) concentrations in the slime fraction,while that of sonicated sludge correlated with protein concentrations in the slime and LB-EPS fractions (p < 0.05).Fluorescent excitationemission matrix analysis showed that the fluorescence matters in the LB-EPS fraction significantly correlated with sludge dewaterability during anarobic digestion. | Huacheng Xu Pinjing He Guanghui Yu Liming Shao | 2011 | Journal of Environmental Sciences2011，23，9： | 13 |

| 8 | 热活化过一硫酸盐调理强化厌氧消化污泥脱水的研究显示文摘为了解热活化过一硫酸盐(PMS)调理对厌氧消化污泥脱水性能的影响,本文以毛细吸水时间(CST)、污泥比阻(SRF)和泥饼含水率(WC)为评价指标,通过比较不同温度条件下(25~80℃)热活化PMS调理过程中PMS分解速率、自由基产生、胞外聚合物(EPS)含量和组成,以及污泥形貌特征和粒径分布等变化规律,探讨作用效果及机理.结果表明,热活化PMS调理能显著改善厌氧消化污泥的脱水性能,且温度的升高可增强脱水改善的程度.在温度80℃、PMS投加量4 mmol·g^(-1)DS(干物质)和处理5 min的条件下,厌氧消化污泥CST、SRF和WC分别从原始污泥的141 s、2.31×10^(13)m·kg^(-1)、85%降至35 s、1.95×10^(12)m·kg^(-1)和63%.热活化PMS调理过程中产生的SO_(4)^(-)·和·OH破坏了污泥絮体结构,大幅消减了TB⁃EPS中的蛋白质(尤其是芳香类蛋白和色氨酸类蛋白),同时污泥粒径的增大(100μm→1000μm)可能是厌氧消化污泥脱水性能提高的主要原因.该结果可为热活化过硫酸盐调理技术应用于厌氧消化污泥的高效脱水提供参考. | 吴秀 方迪 危亚云 顾成语 周立祥 | 2021 | 环境科学学报2021，41，11： | 10 |
| 9 | 活性污泥物理结构对呼吸过程的影响显示文摘物理性能和生物活性是活性污泥法中两个重要的关注方面,为解决运行控制中这两方面的矛盾,对不同活性污泥系统中的污泥物理结构和呼吸过程进行分析.利用7个不同活性污泥系统中的污泥,对其粒径、分形维数、压缩沉降性能、吸附性能和呼吸图谱等方面进行研究分析.结果表明,物理性能指标和呼吸速率之间存在较好的相关关系,其中污泥粒径(d)与内源比呼吸速率(SOUR_e)和最大比呼吸速率(SOUR_t)呈指数负相关(R^2>0.9);分形维数(D_f)与SOUR_e和SOUR_t呈线性负相关(R^2>0.8);压缩指数(SCI)和污泥指数(SVI)与SOUR^2_e呈对数正相关(R>0.9);平衡吸附量(Q_(max))与准内源比呼吸速率(SOUR_q)和SOUR_e呈线性负相关(R^2>0.9).从而得出活性污泥正常运行条件下的最佳物理性能和活性范围:SVI为50~120 mL·g^(-1),SOUR_e为6.27~7.55 mg·(g·h)^(-1),d为205.80~228.12μm,D_f为1.56~1.60,R_(n/t)为0.02~0.03,Q_(max)为508~636 mg·g^(-1). | 郭耀 李志华 杨成建 王慧娟 李亚明 姜阳 | 2019 | 环境科学2019，40，6： | 9 |
| 10 | Enhancement of thermophilic anaerobic digestion of thickened waste activated sludge by combined microwave and alkaline pretreatment显示文摘Pretreatment of thickened waste activated sludge (TWAS) by combined microwave and alkaline pretreatment (MAP) was studied to improve thermophilic anaerobic digestion efficiency. Uniform design was applied to determine the combination of target temperature (110-210℃), microwave holding time (1-51 min), and NaOH dose (0-2.5 g NaOH/g suspended solids (SS)) in terms of their effect on volatile suspended solids (VSS) solubilization. Maximum solubilization ratio (85.1%) of VSS was observed at 210℃ with 0.2 g-NaOH/g-SS and 35 min holding time. The effects of 12 different pretreatment methods were investigated in 28 thermophilic batch reactors by monitoring cumulative methane production (CMP). Improvements in methane production in the TWAS were directly related to the microwave and alkaline pretreatment of the sludge. The highest CMP was a 27% improvement over the control. In spite of the increase in soluble chemical oxygen demand concentration and the decrease in dewaterability of digested sludge, a semi-continuous thermophilic reactor fed with pretreated TWAS without neutralization (at 170℃ with 1 min holding time and 0.05 g NaOH/g SS) was stable and functioned well, with volatile solid (VS) and total chemical oxygen demand (TCOD) reductions of 28% and 18%, respectively, which were higher than those of the control system. Additionally, methane yields (L@STP/g-COD added , at standard temperature and pressure (STP) conditions of 0℃ and 101.325 kPa) and (L@STP/g VS added ) increased by 17% and 13%, respectively, compared to the control reactor. | Yongzhi Chi Yuyou Li Xuening Fei ShaopoWang Hongying Yuan | 2011 | Journal of Environmental Sciences2011，23，8： | 9 |
| 11 | 高铁酸钾破解剩余污泥的水解效能分析显示文摘为了有效提高污泥水解效率、缩短厌氧消化时间,以K2FeO4为氧化剂破解剩余污泥,考察K2FeO4投加量(50~500 g/kg,以干质量计)对污泥破解率的影响,分析水解液各项特征指标并对其可生化性能进行预测,探究该方法作为污泥厌氧预处理的可行性.结果表明:污泥水解效率随着K2FeO4投加量的增加而升高,当搅拌速率为500 r/min、反应时间为2 h、K2FeO4投加量为500 g/kg的条件下,可实现最高的污泥破解率(34.6%).污泥水解液中有机物以多糖、蛋白质为主,并有少量挥发性有机酸;污泥破解过程也伴随着P和NH4^+-N的释放,上清液中ρ(TP)最高可达496 mg/L,且以正磷酸盐为主(约310 mg/L),可对其进行回收.采用三维荧光体积积分的方法对污泥水解液的可生化性能进行预测,发现污泥经K2FeO4预处理后,水解液中RB(易降解有机质)和PB(难降解有机质)荧光强度均明显增加,当K2FeO4投加量为50 g/kg时,F digestion(生物可降解性指数)达到最大值(4.75),预测此时污泥的可生化性能最佳.以K2FeO4为氧化剂预处理污泥可有效提升污泥水解效率,但若作为厌氧消化预处理,应综合考虑污泥破解率和可生化性能.研究显示,搅拌速率为500 r/min、反应时间为2 h、K2FeO4投加量为50 g/kg预处理条件下污泥的可生化性能最佳. | 张皖秋 徐苏云 孙洋洋 张雨辰 | 2020 | 环境科学研究2020，33，4： | 8 |

| 13 | Fenton-絮凝联合调理对污泥脱水性能影响显示文摘为改善污泥脱水性能并比较不同调理方法的优劣,采用絮凝、Fenton氧化及Fenton-絮凝联合对城市污水处理厂剩余污泥进行调理。研究以滤饼含水率、污泥比阻(SRF)、上清液浊度、胞外聚合物(EPS)作为评价指标,综合考察试剂投加量、反应时间、污泥pH等因素对污泥脱水性能的影响及其最佳条件。结果表明:在H2O2、Fe2+的投加量分别为4 g/L、30 mg/L,Fenton反应时间为60 min时,Fenton氧化对污泥絮体的破解效果最佳。该最佳Fenton反应条件下进行污泥絮凝调理,投加CPAM 60 mg/L、调节初始pH为5,污泥调理效果最佳,使得滤饼含水率、上清液浊度、SRF分别降低了24.56%、42.12%、66.67%。Fenton-絮凝联合调理对于污泥脱水性能的改善显然优于单独絮凝调理。Fenton试剂可通过强氧化作用有效破解污泥絮体的EPS,进而有效降低污泥含水率;CPAM的絮凝作用使污泥比阻大大降低,提高了污泥脱水性能。 | 洪飞 孙文全 朱辉 孙永军 周俊 | 2020 | 南京工业大学学报(自然科学版)2020，42，2： | 8 |
| 14 | 污泥中蛋白类物质厌氧转化影响因素及其促进策略研究进展显示文摘蛋白类物质是剩余污泥中的主要有机组分(占有机质的50%~60%),是污泥厌氧消化产沼气的主要底物,其降解率的提升将对剩余污泥厌氧转化效率的提升和脱水性能的强化起到决定性作用。本文首先重点归纳了蛋白质的厌氧转化机制,蛋白质的厌氧降解主要包括蛋白质水解与氨基酸代谢两个重要的步骤,蛋白质的结构与氨基酸组分差异将决定其厌氧转化性能。其次总结了污泥中蛋白类物质厌氧转化的影响因素,包括蛋白质来源、污泥中其他有机物如多糖、无机物如微细砂(二氧化硅)和金属离子、代谢产物如氨氮等。在此基础上归纳了污泥中的蛋白类物质厌氧转化的促进研究,破坏蛋白质的构象、二级结构与氢键网络等将有效强化其厌氧转化性能,其中高温热水解技术能够发挥有效的作用并得到了广泛应用。最后,系统性总结了污泥中蛋白类物质的前沿解析方法包括氨基酸测定方法、荧光光谱法和宏蛋白组学。明晰污泥中蛋白类物质的厌氧转化机制和限制性因素,不仅可以从源头上强化剩余污泥的厌氧转化效率,完善污泥厌氧消化过程中的氮循环理论,还可能从减少亲水性物质的角度改善其后续的脱水性能。 | 陈思思 杨殿海 庞维海 董滨 戴晓虎 | 2020 | 化工进展2020，39，5： | 6 |
| 15 | Effects of activated sludge flocs and pellets seeds on aerobic granule properties显示文摘Aerobic granules seeded with activated sludge flocs and pellets (obtained from activated sludge flocs) were cultivated in two sequencing batch reactors and their characteristics were compared. Compared with granules seeded with activated sludge flocs, those seeded with pellets had shorter start-up time, larger diameter, better chemical oxygen demand removal efficiency, and higher hydrophobicity, suspended solid concentration, and Mg 2+ content. The different inocula led the granule surface with different microbial morphologies, but did not result in different distribution patterns of extracellular polymeric substances and cells. The anaerobic bacterium Anoxybacillus sp. was detected in the granules seeded with pellets. These results highlighted the advantage of pellet over activated sludge floc as the seed for aerobic granulation and wastewater treatment. | Huacheng Xu Pinjing He Guanzhao Wang Liming Shao | 2011 | Journal of Environmental Sciences2011，23，4： | 6 |
| 16 | Relationship between physicochemical properties and dewaterability of hydrothermal sludge derived from different source显示文摘Sewage sludge(SS) and deinking sludge(DS) were used to comparatively study the hydrothermal dewatering of sludge with different components. For a better overview, an insight into the relationship between physicochemical properties and dewaterability of hydrothermal sludge was provided. Results found that not all kinds of sludge were suitably conditioned by hydrothermal treatment(HT) in term of the elevation of dewaterability.Higher hydrothermal temperature tended to enhance the dewaterability of SS rather than DS, which was supported by the variation of their physicochemical properties(including water distribution, bonding energy, extracellular polymeric substance(EPS), particles size,acid functional groups and zeta potential in this study). In addition, the changes in surface morphology suggested that the reverse effect of HT on sludge dewaterability was mainly due to their dewatering behavior. For SS, the destruction of EPS structure leaded to the release of bound water, thereby strengthening sludge dewatering. Conversely, 'Bridging effect' generated by lignocellulose in DS was beneficial for sludge dewatering; however, the increasing hydrothermal temperature degraded part of lignocellulose and weakened'bridging effect', finally resulting in worse dewaterability of DS. | Xiuzheng Zhuang Yanqin Huang Huacai Liu Hongyou Yuan Xiuli Yin Chuangzhi Wu | 2018 | Journal of Environmental Sciences2018，30，7： | 5 |

| 18 | The effect of salinity on waste activated sludge alkaline fermentation and kinetic analysis显示文摘The effect of salinity on sludge alkaline fermentation at low temperature(20°C) was investigated, and a kinetic analysis was performed. Different doses of sodium chloride(Na Cl, 0–25 g/L) were added into the fermentation system. The batch-mode results showed that the soluble chemical oxygen demand(SCOD) increased with salinity. The hydrolysate(soluble protein, polysaccharide) and the acidification products(short chain fatty acids(SCFAs), NH+4–N, and PO_4^(3-)–P) increased with salinity initially, but slightly declined respectively at higher level salinity(20 g/L or 20–25 g/L). However, the hydrolytic acidification performance increased in the presence of salt compared to that without salt.Furthermore, the results of Haldane inhibition kinetics analysis showed that the salt enhanced the hydrolysis rate of particulate organic matter from sludge particulate and the specific utilization of hydrolysate, and decreased the specific utilization of SCFAs. Pearson correlation coefficient analysis indicated that the importance of polysaccharide on the accumulation of SCFAs was reduced with salt addition, but the importance of protein and NH+4–N on SCFA accumulation was increased. | Baodan Jin Shuying Wang Liqun Xing Baikun Li Yongzhen Peng | 2016 | Journal of Environmental Sciences2016，28，5： | 4 |
| 19 | 生物产氢过程中厌氧污泥耐酸响应的生物化学机制显示文摘生物质厌氧发酵产氢过程中积累的大量酸性物质,会对厌氧微生物产生抑制作用,进而制约氢气的持续产生。作者采用不同浓度丁酸对污泥进行胁迫,结果表明:当丁酸胁迫质量浓度为6g/L时,污泥厌氧发酵过程中丁酸、乙酸以及氢气产量最高,分别达到1 071mmol/mol,462mmol/mol和3 690mL/mol,比对照组分别提高了110%,54%和65%;此外,产氢过程中谷氨酸脱羧酶(glutamic acid decarboxylase,GAD)、脱氢酶以及DNA总量活性最高达到11.6μmol/(g·TS·h),6 982.12μg TF/(g.TS.h),14.72ng/mL,相对于对照组分别提高了48%,50%,10.7%;同时,经过酸胁迫后,厌氧污泥胞外聚合物(extracellular polymeric sub-stances,EPS)含量有明显提高,与空白对照组相比松散型多糖和蛋白质以及紧密型多糖和蛋白质分别提高了147%,34.8%,35%,21.6%。因此,适宜浓度的丁酸胁迫可激发厌氧污泥的相关耐酸响应机制(Acid tolerance response,ATR),进而提高污泥的耐酸性能,并最终提高厌氧产氢效率。 | 孟影 张光生 王爱杰 严群 | 2012 | 食品与生物技术学报2012，31，3： | 3 |
