摘要: 采用以沸石为填料的侧向流曝气生物滤池(LBAF)处理生活污水,考察了水力负荷
和气水比对其除污效果的影响。结果表明,在气水比为10:1、水力负荷为0.43 m /(m ·h)的最佳工况下,LBAF对COD、SS、氨氮、总氮和总磷的去除率分别为88.01%、95.18%、78.97%、52.58%和21.02%;将滤池水位增高导致出水氨氮恶化的突变点作为运行终点,开始反冲洗;当在
水力负荷为O.43 m /(m2·h)下运行时,LBAF的反冲洗周期为5 d。
Hybrid Coupled Walls (HCW) are comprised of two or more reinforced concrete wall piers
connected with steel coupling beams distributed over the height of the structure. Extensive
research over the past several decades suggests that such systems are particularly well suited for use in regions of moderate to high seismic risk. This paper reviews the state-of-the-art in seismic modeling, analysis and design of hybrid coupled wall systems. Design methodologies are
presented in both prescriptive and performance-based design formats and a discussion of alterative types of hybrid wall systems is provided.
