Construction technology of Three Gorges Project ship lift hydraulic self-climbing formwork

Dai Zhiqing

Strategic Study of CAE 2013, Volume 15, Issue 9,   Pages 22-26

Abstract:

The construction time limits for the tower column concrete of Three Gorges Project ship lift is pressed for time and require high accuracy. In order to ensure the construction progress and quality, the hydraulic self-climbing formwork is used. This paper focuses on the construction technology of hydraulic self-climbing formwork, improvement measures of self-climbing formwork as well as structural measures made in the plate girders and corbels department of tower to meet the rising-up of self-climbing formwork on Three Gorges Project ship lift tower column concrete. It has been found that application and improvement of the hydraulic self-climbing formwork construction technology meet the design requirements of the tower column cylinder concrete of the Three Gorges ship lift, effectively improve the construction efficiency, save cost, ensure the engineering quality and improve the safety of the construction,can provide reference for other hydropower project construction.

Nitrifying population dynamics in a redox stratified membrane biofilm reactor (RSMBR) for treating ammonium-rich wastewater

Rongchang WANG, Xinmin ZHAN, Yalei ZHANG, Jianfu ZHAO

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 1,   Pages 48-56 doi: 10.1007/s11783-011-0305-7

Abstract: Nitrogen removal performance and nitrifying population dynamics were investigated in a redox stratified membrane biofilm reactor (RSMBR) under oxygen limited condition to treat ammonium-rich wastewater. When the loading rate increased from 11.1±1.0 to , the nitrogen removal in the RSMBR system increased from 18.0±9.6 mgN·d to 128.9±61.7 mgN·d . Shortcut nitrogen removal was achieved with nitrite accumulation of about . Confocal micrographs showed the stratified distributions of nitrifiers and denitrifiers in the membrane aerated biofilms (MABs) at day 120, i.e., ammonia and nitrite oxidizing bacteria (AOB and NOB) were dominant in the region adjacent to the membrane, while heterotrophic bacteria propagated at the top of the biofilm. Real-time qPCR results showed that the abundance of gene was two orders of magnitude higher than the abundance of gene in the MABs. However, the gene was always detected during the operation time, which indicates the difficulty of complete washout of NOB in MABs. The growth of heterotrophic bacteria compromised the dominance of nitrifiers in biofilm communities, but it enhanced the denitrification performance of the RSMBR system. Applying a high ammonia loading together with oxygen limitation was found to be an effective way to start nitrite accumulation in MABs, but other approaches were needed to sustain or improve the extent of nitritation in nitrogen conversion in MABs.
