采用生物接触氧化/混凝沉淀/BAF/微絮凝过滤工艺处理广东省某大型牛仔洗水厂的洗水废水,运行结果表明,该工艺处理此类牛仔洗水废水技术可靠,经济合理,当进水COD、色度、SS平均浓度分别为360 mg/L、480倍、380 mg/L时,处理出水分别为25 mg/L、5倍、5 mg/L,与处理过的河水按1:1混合后可稳定回用于生产. 相似文献

采用化学沉淀预处理/人工快渗工艺深度处理酸洗磷化废水。运行结果表明:当进水磷酸盐为80~90 mg/L时,出水磷酸盐浓度<0.12 mg/L,去除率达到99.8%以上。出水水质能稳定达到《污水综合排放标准(》GB 8978—1996)的新扩改二级标准。该新工艺具有处理效果好、运行费用低、出水水质稳定等优点,为酸洗磷化废水的工程设计提供了一种新思路。 相似文献

广东某万头规模化猪厂废水主要为猪粪水和猪栏冲洗水,其COD和NH3-N浓度高,常规工艺难以处理达标。针对该水质特点,采用EGSB/生物接触氧化/MBR组合工艺进行处理。调试运行结果表明,该组合工艺处理效果良好,对COD和NH3-N去除率高,出水水质稳定达到广东省《畜禽养殖业污染物排放标准》(DB 44/613—2009)珠三角地区标准。 相似文献

以船舶含油废水重力除油罐出水为研究对象,采用混凝沉淀/好氧生物处理组合工艺对其进行处理,重点考察了高浓度的Cl-对好氧生物系统处理效果的影响,以及由高浓度Cl-引起的活性污泥生物相演替规律。结果表明,该组合工艺能在Cl-浓度高达9 256 mg/L的条件下稳定运行,系统出水COD、TOC和石油类可分别降至(80~85)、(25~30)和(1.0~1.5)mg/L,达到了《污水综合排放标准》(GB 8978—1996)的一级标准。高浓度的Cl-对生物处理系统的影响较大,Cl-为4 000 mg/L是对未驯化活性污泥产生抑制作用的转折点;在高Cl-浓度下,降低Cl-浓度比增加Cl-浓度对生物处理系统的影响更大,良好的驯化过程和稳定的进水水质是高浓度Cl-废水实现有效生物处理的重要保证。 相似文献

‘Fabric is the perfect mediator between the firm and the flowing.’ Nigel Coates celebrates the textile's rediscovery as a metaphor for the architectural envelope, liberating it from its reputation as having only a supporting, ‘comfort role’ in the interior. He describes his own experiments with textiles at Branson Coates Architecture and the Royal College of Art (RCA), in which they alternately become skin, weave and pattern operating at every scale from the individual body to the urban plan.

Design-build has been receiving much attention from both the profession and academia in recent years. However, there seems to be many differences in the way that the term is interpreted and applied. This paper reflects upon the results of a conference entitled "Designing/Building/Learning" that sought to explore the issues surrounding this topic through paper sessions, workshops, keynote addresses, and panel discussions. Hands-on approaches to pedagogy in the form of full-scale construction exercises have emerged in schools across the country, but these activities continue to resist theorizing. The Designing/Building/Learning Conference demonstrates this resistance, as well as the compelling role of design-build in education. 相似文献

While attention was riveted on the results of an international design competition for a site over the 34th Street rail yards west of Pennsylvannia Railroad Station, another study was taking place. Working with the community, local multidisciplinary design teams explored an adjacent site through a different process. This process, and its findings, are illuminating. 相似文献

AA第5单元媒介课的任务是设计一个地处伦敦的旅馆,并且用电影预告片作为主要设计的工具.我们相信在通过影像来提炼虚拟场景的过程中.可以产生建筑思维.这些景象并不仅仅关注空间的物质实体,而且包含着与行为有关系的特定空间环境的情节.为了解读所有这些传统建筑讨论中(大多只是平面一立面一模型的联系)常被忽略的空间维度.电影媒介是一个理想的工具.在不同种类的电影表现方式中.我们选择了"预告片".预告片并不讲述电影本身,而是通过激起电影的氛围来诱惑观众.制作一个预告片描述一个还不存在的旅馆,我们打算通过激发氛围、暗示可能的场景等这些超越传统建筑设计过程的做法,得到一个非常复杂的空间. 相似文献
