It is well-known that the conventional supported catalyst powders usually suffer from a large flow resistance, and the poor heat transfer through the powders will easily lead to unacceptably non-uniform temperature distributions.However, the structured catalyst have smaller characteristic lengths, larger surface to volume ratio, and more compact size, and therefore have the advantages of intensified heat and mass transfer, improved reaction efficiency, and ease of use in portable applications.Typical examples include the microreactors [1], mieorfibrous composites bed [2] reactor and monolith structured reactor [3], which supported Ru or Ni catalysts exhibiting good activity for ammonia decomposition.

本文建立了水中草甘膦残留的高效液相色谱-柱后衍生检测法,该方法省却了繁琐以及对环境不友好的前处理步骤,直接进样测定.该方法的最小检出限为0.005mg/L,回收率在82％-95％之间,准确灵敏,在实际生产中应用非常广泛.
本文以淮河中段H市为例,沿淮河垂向设置试验井,研究了试验井与河岸间距离对岸滤除污染效能的影响规律.研究结果表明,岸滤是一种自然、可靠、运行成本低的预处理工艺,能有效降低河流水源水中的污染物浓度,同时缓解河流水污染高峰对后续处理工艺的冲击负荷,起到较好的屏障作用.岸滤对有机物、氨氮和浊度的平均去除率分别为：57.0％～84.0％,45.4％～92.9％以及85.4％～98.6％.针对水质波动性较大的
本研究采集天然含藻原水并配制特定藻类数量水样进行前氧化搭配混凝程序实验，探讨加氯前氧化(次氯酸钠及二氧化氯)对藻类细胞特性(藻体结构、叶绿素a与藻类破损程度)之影响，并了解前氧化搭配不同混凝剂(聚硅酸铁及硫酸铝)对含藻原水之混沉效能及上澄液过滤性之影响。研究结果显示，在氧化程序中，次氯酸钠与二氧化氯氧化均能破坏藻类细胞，致使藻类活性降低，提升藻类之沉降性，因二氧化氯氧化对藻类之破坏性较次氯酸钠氧化
本研究主要针对惠勒式快滤池进行丰水期与枯水期两不同时期之TRI值实场试行以探讨在不同水质情况下之试行结果.藉由实场两个快滤操作好坏差异较大滤池(1号池与2号滤池)在枯水期间(水质变动小)各别的三次滤程比较发现,TRI值皆为在0.5-0.6之间,整体变动性相当稳定,因此TRI值无法有效辨别两者之差异进而反映滤床状况差异,所以不利于作为过滤效能操作指标探讨.于丰水期(或水质变动大)时两滤池之TRI值则
为增加净水污泥之再利用价值及广度,增加净水污泥之再利用方法,落实本公司资源永续利用之政策。台水公司与中华民国轻质骨材协会合作,成功开发以净水污泥制作成新的环保绿建材—轻质骨材。研究成果显示,净水污泥制作之轻质骨材,其混凝土的抗压强度超过50 MPa,可用于建造如台北101的超高层建筑物或大型的桥梁,更重要的是,可使整个结构物至少降低1/4的重量,对于抑制地层下陷有很大之帮助,亦可提高结构物的耐震度
