The Major Root Causes of Smog in China and Technologies and Solutions to Reduce It

Ke Liu

Frontiers of Engineering Management 2016, Volume 3, Issue 4,   Pages 343-348 doi: 10.15302/J-FEM-2016053

Abstract: This paper discusses the two major root causes of smog in China. The first one is the distributed coal combustion in many small and medium sized boilers which have no emission control systems installed. To resolve this problem, there are several ways, such as increasing the centralized coal combustion for heat and power cogeneration; or converting coal to SNG in areas where there is enough water resource and removing the pollutants of the coal in the centralized coal to SNG plant, or refining the coal and making it cleaner first before combustion. The second major cause of smog is the low quality diesel and outdated diesel engines used in China. To solve this problem, there are some ways, such as improving the diesel quality to meet the national V standard, and meanwhile, enhancing the law enforcement to eliminate these outdated diesel engines that do not meet the national emission standards; in addition, combusting cleaner and cheaper fuel such as methanol or DME in the diesel engines is also an option for certain areas where there are abundant alternative fuels such as methanol to replace diesel.

Key problems and solutions in arch dam heightening

Zuoguang FU, Yunlong HE, Sheng SU

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 1,   Pages 98-104 doi: 10.1007/s11709-010-0004-7

Abstract: The dam heightening, which is an effective way to increase reservoir volume, has been paid close attention by engineers. Three problems should be dealt with when an arch dam needs to be heightened: stress state getting worse at dam heel, cracking on new added concrete dam surface, and weak bonding between new added concrete and old dam. Taking Geba arch dam as an example, these problems are examined in details through simulation analysis by the finite element method. The tensile stresses on dam’s surface and joint face that have certain relations to the dam heightening can be controlled by some measures.

Possible solutions for sludge dewatering in China

Wei WANG, Yuxiang LUO, Wei QIAO,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1,   Pages 102-107 doi: 10.1007/s11783-010-0001-z

Abstract: In China, over 1.43×10 tons of dewatered sewage sludge, with 80% water content, were generated from wastewater treatment plants in 2007. About 60% of the COD removed during the wastewater treatment process becomes concentrated as sludge. Traditional disposal methods used by municipal solid waste treatment facilities, such as landfills, composting, or incineration, are unsuitable for sludge disposal because of its high water content. Disposal of sludge has therefore become a major focus of current environmental protection policies. The present status of sludge treatment and disposal methodology is introduced in this paper. Decreasing the energy consumption of sludge dewatering from 80% to 50% has been a key issue for safe and economic sludge disposal. In an analysis of sludge water distribution, thermal drying and hydrothermal conditioning processes are compared. Although thermal drying could result in an almost dry sludge, the energy consumption needed for this process is extremely high. In comparison, hydrothermal technology could achieve dewatered sewage sludge with a 50%–60% water content, which is suitable for composting, incineration, or landfill. The energy consumption of hydrothermal technology is lower than that required for thermal drying.

Controlled synthesis of uniform silver nanowires with high aspect ratios in aqueous solutions of gemini

XU Jian, LIU Weijun, LIU Honglai, HU Ying

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 3,   Pages 221-227 doi: 10.1007/s11705-007-0040-6

Abstract: A simple solution-phase approach has been demonstrated for the large-scale synthesis of silver nanowires with diameters in the range of 15 25 nm, and lengths usually in the range of tens of micrometers. In the presence of gemini surfactant 1,3-bis(cetyldimethylammonium) propane dibromide (16-3-16), the growth of silver could be directed into a highly anisotropic mode to form uniform nanowires with aspect ratios up to about 2,000. X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), X-ray powder diffraction (XRD), electron diffraction (ED), and UV-vis absorption spectroscopy, were used to characterize the as-prepared silver nanowires, indicating the formation of a highly pure phase, good crystallinity, as well as a uniform diameter.
