    • A method for reducing recalcitrant chemical oxygen demand (COD) of a liquid in a water system is provided. The method comprises pretreating the liquid in a pretreatment unit (12) to remove indigenous bacteria or microbes to a population level below which the indigenous organisms can interfere with the screened and externally introduced microorganisms. The liquid is then provided to a reactor (20) that has a filter bed (22) formed with a carrier material (26). Special microbes are screened and used to colonize the carrier material (26) to remove recalcitrant COD. A biofilm is cultured on the surface of the carrier material (26) to immobilize the screened microbes in the reactor (20). The method further comprises adding a co-substrate as the liquid enters the reactor (20) and percolating the liquid through the filter bed (22) colonized with the screened microbes to degrade at least part of the recalcitrant COD under aerobic conditions. The screened microbes comprise at least one microbial species selected from the group consisting of Bacillus, Comamonas, Arthrobacter, Micrococcus, Pseudomonas, Pediococcus, Achromobacter, Flavobacterium, Mycobacterium, Rhodanobacter, Stenotrophomonas and yeast.
    • 提供了一种降低水系中液体的难溶化学需氧量(COD)的方法。 该方法包括将预处理单元(12)中的液体预处理以将本地细菌或微生物除去至低于该水平的本地生物可能干扰被筛选和外部引入的微生物的群体水平。 然后将液体提供到具有形成有载体材料(26)的过滤床(22)的反应器(20)。 将特殊微生物筛选并用于定植载体材料(26)以除去顽固的COD。 在载体材料(26)的表面上培养生物膜,以将筛选的微生物固定在反应器(20)中。 该方法还包括当液体进入反应器(20)时加入共底物,并将液体渗透通过筛选的微生物定殖的过滤床(22),以在有氧条件下降解至少部分顽固性COD。 所筛选的微生物包含至少一种选自芽孢杆菌属,科马矛菌属,节杆菌属,微球菌属,假单胞菌属,类球菌属,无色杆菌属,黄杆菌属,分枝杆菌属,罗丹霉属,嗜麦芽寡养单胞菌属和酵母菌的微生物。

    • A rotor blade for a turbine (12) of a gas turbine (10) includes an airfoil (25). The airfoil (25) may have a leading edge (28), a trailing edge (29), an outboard (31), and an inboard end that attaches to a root (21) configured to couple the rotor blade to a rotor disc. The airfoil (25) may have a cooling configuration that includes elongated cooling channels (33) for receiving and directing a coolant through the airfoil (25). The rotor blade may further include: a tip shroud (55) connected to the airfoil (25); outlet ports (37) formed through an outboard face (60) of the tip shroud (55) that fluidly communicate with the cooling channels; and flow directing structure formed on the outboard surface (60) of the tip shroud (55). The flow directing structure may be positioned relative to the outlet ports (37) and configured for directing the flow of coolant discharged from the outlet ports (37). The rotor blade may be useful to reduce local tip shroud temperature as well as improved stage aerodynamic efficiency by reducing the coolant supply needed to maintain the component at desired temperature levels.
    • 一种用于燃气轮机(10)的涡轮机(12)的转子叶片包括翼型件(25)。 机翼(25)可以具有前缘(28),后缘(29),外侧(31)和内侧端部,该内侧端部连接到构造成将转子叶片耦合到转子盘的根部(21)。 翼型件(25)可以具有冷却构造,其包括用于接收和引导冷却剂通过翼型件(25)的细长的冷却通道(33)。 转子叶片还可以包括:连接到翼型件(25)的尖端罩(55); 通过与冷却通道流体连通的末端罩(55)的外侧面(60)形成的出口(37) 以及形成在尖端罩(55)的外侧表面(60)上的流动引导结构。 流动引导结构可以相对于出口(37)定位并且被配置为引导从出口(37)排出的冷却剂流。 转子叶片可用于通过减少将组件保持在所需温度水平所需的冷却剂供应来减少局部尖端护罩温度以及改善的阶段空气动力学效率。
