Comparison of startup and anaerobic wastewater treatment in UASB, hybrid and baffled reactorAbstractAn experimental study was carried out to compare the performance of selected anaerobic high rate reactors operated simultaneously at 37 °C. The three reactors,namely up¯ow anaerobic sludge bed reactor (UASB), hybrid of UASB reactor and anaerobic ®lter (anaerobic hybrid reactor ± AHR) and anaerobic baf¯edreactor (ABR), were inoculated with the anaerobic
摘要:本文從四個層面探討了景觀的含義:(1)景觀作為視覺審美的對象,在空間上與人物我分離,景觀所指表達了人與自然的關系、人對土地、人對城市的態度,也反映了人的理想和欲望;(2)景觀作為生活其中的棲息地,是體驗的空間,人在空間中的定位和對場所的認同,使景觀與人物我一體;(3)景觀作為系統,物我徹底分離,使景觀成為科學客觀的解讀對象;(4)景觀作為符號,是人類歷史與理想,人與自然、人與人相互作用與關系在大地上的烙印。因而,景觀是審美的、景觀是體驗的、景觀是科學的、景觀是有含義的。 關鍵詞: 景觀, 場所, 風景Meanings of Landscapes Yu Kongjian Beijing University Center for Landscape Architecture and PlanningTuren Design InstituteAbstract: This paper discussed the meanings of landscapes in four aspects: (1)Landscape
