Authors: Wu Wen Zhong
Published: December 2014

Fire-proof paint thickness is of importance to steel structure fire safety, and the common programme iteratively solves its heat conduction equation in fire-insistence test, while by dimensional analysis in the equation, this paper constructs a function of steel structure section-material grouped parameter, and also a similarity form is employed to form a relationship between any two different transient fires, then solves the grouped parameters in two other transient fires. Parameter comparisons among these 3 fires conclude: with the same fire time, fire-proof paint and size, fire-proof paint thickness is necessary to be the biggest in fire-insistence test, and smaller in site fire, and the smallest in t-square fire. The key factor to decide the thickness is surface temperature outside fire-paint. The common programme is with some redundance, and more reasonable guard should add to the steel structure in t-square fire. The foregoing analysis to fire-proof paint thickness by the function of steel structure section-material grouped parameter and the similarity form between any two different transient fires, broadens the common programme to any transient fires.

Published: December 2014

The iterative formulas of spring forces for Circumferential Arc Spring Dual Mass Flywheel (DMF-CS) were derived by discrete method, involving friction forces. The computation program was designed, and the curves illustrating transmitted torques over deformation angles of the outer and inner arc springs were plotted, which showed linear torque behavior. Thus two stages of torsional stiffness of DMF-CS were figured out to be 465.9923Nm/rad and 631.7980Nm/rad. The two stages of torsional stiffness without friction forces were calculated by this method, which were 434.6408Nm/rad and 591.3652Nm/rad. The experiment of static torque characteristic of DMF-CS was completed, obtaining the experimental torsional stiffness, which were 455.9923Nm/rad and 620.9412Nm/rad. Comparing the above values of torsional stiffness, the values with friction forces show more precise than ones without friction forces, and the values without friction forces are smallest. The results show that the friction forces contribute to the torsional stiffness of DMF-CS.

According the living and breeding habits of key species, typical representatives are selected to establish the grading standards of ecological health and evaluate ecosystem health as well as the effect of eco-hydrology regulation under cascade development of typical reservoirs. Results show that the annual distribution of runoff tends to be balanced, with reduced amount of suspended sediment in downstream; species fond of shallow water and rapids suffered decreased habitat space and a decline in its number, resulting in decreased diversity of fish species; and the quality of some river segments failed to meet the standard.

A method of simulation modeling and virtual presentation of river evolution was proposed. The method used a variable scale modeling method to generate virtual environment and the data model of irregular triangle network to build the river channel. The virtual environment and the river channel are unified with seamless splicing algorithm to enhance the sense of immersion. And then digital river simulation platform was developed. It displayed the erosion and deposition of river channel with color mapping and presented an efficient algorithm to analyze the change of section shape. The proposed method is validated by application in analyzing the sediment deposition and erosion of Chongqing reach of Yangtze River.

Fate of POPs and its Laboratorial Technics under Combined Plants Cultivation
Authors: Lei Zhi Hua
Published: December 2014

The removal of persistent organic pollutants (POPs) in soils at initial concentrations ranging from 20.00 to 321.05 mg·kg-1 was investigated under different planting patterns, and enhancement mechanisms were analyzed. Results showed that the dissipation of POPs in soils growing Brassica campestris and Medicago sativa significantly exceeded those vegetating single species. During 70-day experiment, about 75.06% of Pyr and 68.22% of BaP was removed from the soils under mixed cropping; while only 31.8% and 64.03% of Pyr and 27.84% and 51.93 of BaP were removed under single rape and alfalfa cropping, respectively. Of all pathways enforcing POPs removal, plant-microbial interactions is the most predominant. These results suggested a feasibility of the establishment of multi-species phytoremediation for improvement of the remediation efficiencies of POPs, which may decrease accumulations of POPs in crops and thus reduce their risks.

Authors: Zhai Jian , Jiang Chun Hua , Zhou Jin
Published: December 2014

A biotrickling filter has been set up in WWTP of Nanjing petrochemical factory for about 6 months. The purpose of this project was to assess the ability of the biotrickling filter to remove hardly biodegradable VOCs such as benzene, toluene, ethylbenzene and xylene which are recalcitrant and poorly water soluble and commonly found in petrochemical factories. PUF cubes (1 cm3) were used as the packing media treated with large amounts of circulating mineral salt medium added with bacterial species which came from secondary sedimentation tank of WWTP of Nanjing petrochemical industry. The controlled empty bed retention time (EBRT) of 90 s was a key parameter for reaching a removal efficiency of 91.7 %, 88.3 %, 70.7 % and 63.5 % for toluene, ethylbenzene, benzene and xylene, respectively. The analysis of the bacterial community in the BTF during VOC removal showed that Pseudomonas putida and Klebsiella sp. phylum were dominant microbes.

There are many methods of municipal solid waste disposal, among them, one of the most convenient methods is landfill. However, leachate and landfill gas produced in the process of landfill cause secondary pollution and endanger human health. As landfill site working, there are some problems, such as fire and explosion, collapse of garbage body and other safety hidden trouble. In order to solve the safety problems during the process of landfill, the manuscript analyzed the reasons of the safety accidents from people’s unsafe behavior, unsafe status of machinery, material or environment, defect in safety management, also proposed the management strategies from landfill design and management .
Treatment of Coking Wastewater by a Submerged Membrane Bioreactor with Suspended Carriers
Authors: Gu Qi Yuan , Li Ming Yue
Published: December 2014

A renovated hybrid membrane bioreactor (HMBR) was investigated for its capability of coking wastewater treatment. The HMBR combined biofilm process and membrane filtration process. The system was efficient in degrading COD and phenol in coking wastewater and controlling membrane. It was found that the coking wastewater could be effectively treated with 88.6% of COD removal efficiency and 98.3% of phenol removal efficiency at hydraulic retention time (HRT) of 16 h. The removal efficiency of COD and phenol decreased gradually down to 83.2% and 97.7% when HRT decreased to 8 h. The long term experiments indicated that the degree of membrane fouling for HMBR was far lower than that for MBR. The scrubbing effect of suspended carrier in HMBR was observed to be capable of reducing the cake fouling of membrane. The operation time of HMBR was 8.4-fold longer than that with MBR.
