Lei SHEN,Yuntao GUAN,Guangxue WU,Xinmin ZHAN

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 776-783 doi: 10.1007/s11783-013-0586-0

Abstract: N O emission from a sequencing batch reactor (SBR) for biological nitrogen and phosphorus removal fromO emission and to study the effects of heterotrophic activities on N O emission during nitrification.The results showed that N O emission was mainly attributed to nitrification rather than to denitrificationN O emission during denitrification mainly occurred with stored organic carbon as the electron donor.The ratio of N O emission to the removed ammonium nitrogen (N O-N/NH -N) was 2.5% in the SBR system with

Abstract: The N O production in two nitrogen removal processes treating domestic wastewater was investigated inResults showed that N O emission happened in the aerobic phase rather than in the anoxic phase.The dissolved N O was reduced to N in the anoxic denitrification phase.Higher nitrite accumulation resulted in higher N O emission in the short-cut nitrogen removal processPulse-wise addition of 20 mg gave rise to 3-fold of N O emission in the conventional N-removal process

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 6, doi: 10.1007/s11783-017-0976-9

Abstract: N O is a powerful greenhouse gas and plays an important role in destructing the ozone layer.This present work investigated the effects of Pd doping on N O formation over Pt/BaO/Al O catalyst.Compared with Pt/BaO/Al O , (Pt/BaO/Al O +Pd/Al O ) produced less N O and more NH during NO storageN leading to a decrease in N O formation.Most of N O formed over (Pt-Pd/BaO/Al O +Al O ) was originated from Pd/BaO/Al O component.

Frontiers of Engineering Management 2019, Volume 6, Issue 3,   Pages 395-405 doi: 10.1007/s42524-019-0019-2

Abstract: Recycled concrete is a material with the potential to create a sustainable construction industry. However, recycled concrete presents heterogeneous properties, thereby reducing its applications for some structural purposes and enhancing its application in pavements. This paper provides an insight into a solution in the deformation control for recycled concrete by adding supplementary cementitious materials fly ash and blast furnace slag. Results of this study indicated that the 50% fly ash replacement of Portland cement increased the rupture modulus of the recycled concrete. Conversely, a mixture with over 50% cement replacement by either fly ash or slag or a combination of both exhibited detrimental effect on the compressive strength, rupture modulus, and drying shrinkage. The combined analysis of environmental impacts and mechanical properties of recycled concrete demonstrated the possibility of optimizing the selection of recycled concrete because the best scenario in this study was obtained with the concrete mixture M8 (50% of fly ash+ 100% recycled coarse aggregate).
