An integrated method for the rapid dewatering and solidification/stabilization of dredged contaminated

Hefu Pu, Aamir Khan Mastoi, Xunlong Chen, Dingbao Song, Jinwei Qiu, Peng Yang

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 4, doi: 10.1007/s11783-020-1359-1

Abstract: Using this method, dewatering and solidification/stabilization can be carried out simultaneously suchperformance compared to the conventional S/S method that uses Portland cement (PC) directly without prior dewatering

A full-scale integrated-bioreactor with two zones treating odours from sludge thickening tank and dewatering

Jianwei Liu, Kaixiong Yang, Lin Li, Jingying Zhang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 4, doi: 10.1007/s11783-017-0932-8

Abstract: A full-scale integrated-bioreactor consisting of a suspended zone and an immobilized zone was employed to treat the ordours emitted from a wastewater treatment plant. The inlet concentrations of H S and NH were 1.6–38.6 mg·m and 0.1–6.7 mg·m , respectively, while the steady-state outlet concentrations were reduced to 0–2.8 mg·m for H S and 0–0.5 mg·m for NH . Both H S and NH were eliminated effectively by the integrated bioreactor. The removal efficiencies of H S and NH differed between the two zones. Four species of microorganisms related to the degradation of H S and NH were isolated. The characteristics and distributions of the microbes in the bioreactor depended on the inlet concentration of substrates and the micro-environmental conditions in the individual zones. Product analysis indicated that most of the H S was oxidized into sulfate in the immobilized zone but was dissolved into the liquid phase in the suspended zone. A large amount of NH was converted into nitrate and nitrite by nitration in the suspended zone, whereas only a small amount of NH was transferred to the aqueous phase mainly by absorption or chemical neutralization in the immobilized zone. Different microbial populations dominated the individual zones, and the major biodegradation products varied accordingly.

Construction technology in huge caisson on the ground

Qiu Qionghai,Lin Fan,Jiang Jianghua

Strategic Study of CAE 2010, Volume 12, Issue 4,   Pages 14-20

Abstract:

Taizhou Changjiang River Highway Bridge is a suspension bridge with three towers, two spans and two anchorages. The main span is 2×1 080 m. The south and north foundation of the anchorages are deep water caisson with rectangular plane size 67.9 m×52.0 m. A great many of technical innovations are adopted to solve many technical problems including the disposal of the compound basement, manufacturing and installation of the caisson, fulfillment of concrete in the caisson etc, based on the conditions such as the thick overburden layer at the top of the caisson, the super dimension and the big sinking depth of the caisson. This article gives a brief introduction on construction technologies in huge caisson on the ground and can be taken as a reference during the construction of the super scale caisson on the ground in the future.

Keywords： suspension bridge     anchorage     caisson     assembly     deep-well dewatering     foundation settlement     air suction
