摘要：机织滤布的透水性能会直接影响过滤设备的生产效率。为理清滤布材质、微观结构与过水通量之间的相互关系,定制一批控制变量的滤布用于实验。对不同材质的滤布进行了FTIR,动、静态接触角和表面能测定,从机理分析了材质影响过水通量的关键性指标。对滤布微观结构进行了SEM表征,并分析了编织方式、厚度、孔径对过水通量的影响,建立了滤布微观结构与过水通量的半经验模型。结果表明:材质亲水性大小顺序为聚丙烯>聚碳酸酯>聚酰胺,对应的过水通量分别为6.34、5.75、5.46 m/min,亲水性强的材质具有更大的过水通量;微观结构中,过水通量大小顺序为缎纹滤布>斜纹滤布>平纹滤布,孔径、厚度分别与过水通量呈正、负相关关系,拟合的微观结构与过水通量的半经验模型可以为机织滤布的选型提供理论参考。

杨雅琼等：3种固定式填料在中试IFAS系统中的性能比较及菌群结构解析
摘要：为考察固定式填料在生物膜-活性污泥工艺(IFAS)中的性能和菌群结构,选取弹性立体填料、组合填料以及自制填料3种固定式填料投入中试级别的IFAS反应器好氧池中进行对比,另于小试系统中进行3种填料的脱膜实验。结果表明:组合填料的亲水性最高(接触角为38°),生物膜厚且致密,加上结点的存在,易结团,脱膜率最高为63%;弹性填料21 d基本可以完成生物膜的更新;而自制填料脱膜速率先快后慢,第24天时脱膜率高达80%。在系统运行期间,3种填料对COD、氨氮去除率均在90%以上,出水均达到一级A排放标准。自制填料和组合填料系统的总氮去除率高于弹性填料。当自制填料系统运行27 d以后,TN出水可稳定达到一级A排放标准。与组合填料和弹性填料相比,由于自制填料结构的特殊性,其负载的生物量最多,生物多样性最高,同时,对硝化细菌、反硝化菌和反硝化除磷菌均表现出富集优势。

李云辉等：A/O工艺曝气充氧性能的评估和优化潜力分析
摘要：以上海市某污水处理厂A/O工艺好氧池为研究对象,在线监测好氧池沿程的耗氧速率和氧利用率(OTE),结合好氧池的曝气量、DO、进出水污染物指标,对曝气充氧性能进行综合评估。通过核算该污水处理厂实际需氧量和实际供氧量,计算曝气系统的节能潜力。结果表明:(1)该污水处理厂好氧池OTE为22.54%～28.82%,曝气量为4.24～9.63m~3/h。曝气量与OTE的变化呈明显的负相关,说明好氧池中的曝气器可能受到一定程度的污染。(2)距好氧池进水口5～45m,活性污泥比耗氧速率(SOUR)在12～16mg/(g·h)内波动,在实际经验值8～20mg/(g·h)内。60、100、140m处SOUR低于8mg/(g·h),处理负荷偏低,存在曝气过量和池容浪费的情况。(3)好氧池供气量、需气量分别为89 968.99、76 885.15m~3/d,节能潜力较大。

莫惠珺等：型式结构对双曲面搅拌器流场影响的数值模拟
摘要：基于多重参考系法（multiple reference frame model,MRF）,采用标准k-ε模型对双曲面搅拌器的流场分布特性开展了数值模拟研究,重点对实心、空心、有孔和高叶片4种不同型式结构的双曲面搅拌器的流场结构、流速分布、湍动能分布、有效搅拌体积以及功耗特性进行了对比分析。结果表明,高叶片结构的双曲面搅拌器更有利于形成对称且均匀的流场,底部湍动更强烈,搅拌范围更广且混合效果最佳。在转速为200 r·min-1时,高叶片双曲面搅拌器达到搅拌要求时单位能耗分别仅为前3种结构的74.09%、61.19%和61.88%,其节能效果显著。

穆云松等：3D-QSARs and molecular dynamics simulation studies on induced fit binding of flavones to human aldose reductase.
ABSTRACT: Flavones, natural compounds found in plant, are one of emerging endocrine disrupting chemicals, but little is known about potential inhibition of structurally diverse flavones towards human aldose reductase (hALR2). In the present study, three-dimensional quantitative structure-activity relationships (3D-QSARs) models, comparative molecular similarity indices analysis (CoMSIA) and comparative molecular field analysis (CoMFA) were established to explore the structural specificity and

ABSTRACT: Natural adsorbent was optimized from four natural adsorption materials (kaolin, bentonite, diatomite, and natural zeolite) through the comparison of their ability to recover organic matter from an ultra-short-sludge-retention-time (ultra-short-SRT) activated sludge process effluent. Natural zeolite was modified by the loading of three types of chemical coagulants (Fe2(SO4)3, Al2(SO4)3, and ZnSO4) and was used for the study of the advanced recovery of organic matter. The results of B
