Identification of gale weather with doppler weather radar data 用多普勒天气雷达资料识别大风天气
Jinliang Zhou, M. Wei, Tao Wu, Nan Li
With high temporal and spatial resolution, Doppler weather radars are important means for revealing structures and revolution of meso-micro scale weather processes. This article uses reflectivity characteristics to identify convective gale weather. 6 promising identification parameters are proposed (CR, VIL, DVIL, SWP, DCRH and SPEED), and an automated identification algorithm for convective gale is established based on fuzzy logic principles. 6 typical cases are used to obtain probability distribution characters based on the statistics of volume scan data, and then it is determined that CR, VIL, DVIL and SWP that have more concentrated probability densities are used as the input variables of the fuzzy logic technique for the identification of the convective gale. According to the statistics, these parameters can effectively identify convective gale. The algorithm identifies 150 from 174 gale wind events in 6 weather processes, with a POD probability 86.21%.

Polarimetric roll-invariant three-component scattering model and application to terrain classification 偏振滚动不变三分量散射模型及其在地形分类中的应用
Hong-zhong Li, Liming Jiang, Lin Liu
Inspired from the Freeman-Durden three-component model, a roll-invariant three-component scattering decomposition model is proposed for polarimetric SAR data in this paper. Three points of modification are included in the model. Firstly, the deorientation procedure is introduced into the scheme to make the decomposition results roll invariant. Secondly, a modified volume scattering covariance matrix is proposed to better match the deorientation volume scattering. Lastly, the symmetry test is introduced to measure the reflection symmetry of the scatterer. Then the roll-invariant model is combined with the maximum likelihood classifier to apply to the terrain and land-use classification.

Zhiquan Yang, G. Liu
A modified oxidation ditch process is applied in a full-scale municipal wastewater treatment plant. Compared with the conventional oxidation ditch, the modified oxidation ditch adds some microporous aerators to improve oxygen utilization. The measures bring about a further improvement of nitrogen and phosphorus in the urban wastewater. The monitoring results for one year show that the influent concentrations of SS, COD, NH4-N and TP are 160–320, 170–320, 8–16, 2.5–4.0 mg/L, respectively. And the influent pH and temperature are 7.0–8.5 and 17–27 °C. Afte the treatment of modified oxidation ditch process, the average effluent concentrations of SS, COD, NH4-N, TP are 18, 20, 2.4, 0.8 mg/L, and the average removal rates are 92%, 90%, 80%, 60%, respectively. The effluent pH is consisted with the influent pH. The removal efficiency of nitrogen and phosphorus can be kept at good efficiency, in spite of the fluctuation of temperature. The effluent quality meets the 1 B level discharging criteria in China.

Junmin Gao, Ying Zhang, Jinsong Guo, Ke Zhang, R. Yuan, Fen Jin
The occurrence and fate of organotins compounds in drinking water plant in Chongqing of southern China was investigated for the first time. Water samples were extracted by solid phase micro-extraction (SPME) and measured by gas chromatograph (GC) with mass spectrum (MS). Results showed the presence of organotin pollution in drinking water plant in Chongqing and most of organotins was MBT with the highest level of 120.78ngSn/l. Sometimes DBT, MPT and DPT were found. Little endocrine disruptors of TPT (2.77 ngSn/l) was also found occasionally, but TBT was not found. Conventional water treatment process could not removed organotins effectively.

An experimental study of sulphur capture with cement raw meal and its volatility at a high temperature 水泥生料捕硫及其高温挥发性的实验研究
Y. Ji, Delong Xu, Shaowu Jiu, Kang Yang, Aiwu Yang
Experiments were carried out to study the process of sulphur dioxide capture with cement raw meals, and effects of sulphur evaporation (i.e. the captured sulphur in the raw meal evaporates into SO2 at a calcination temperature) on the efficiency such a process. In the study, four samples of raw meals with various ingredients were prepared; with a combined application of DSC-TGA-FTIR, the amount /degree of SO2 released from those samples under normal atmosphere were measured /analysed based on measurements results with TG, DSC, DTG and IR 3D imaging / mapping. Results as obtained showed that: 1. the amount of released SO2 increased with an increase of sulphur content in raw meals when temperature increases from 35 °C to 1450 °C; 2. a higher temperature is required to initiate SO2 releases when the sulphur content in raw meals is lower. Such results are in an agreement with a fact that a decrease sulphur content in a raw meal leads to a significant increase its melting and calcinating temperature, and preventing the formation of liquidus, and sulphur from evaporating.
通过实验研究了水泥生料捕集二氧化硫的过程,以及硫蒸发(即生料中捕获的硫在煅烧温度下蒸发成SO2)对捕集二氧化硫效率的影响。在这项研究中,准备了四种不同成分的生食样品;结合DSC- tga - ftir技术,利用TG、DSC、DTG和IR三维成像/测绘的测量结果,对正常气氛下样品中SO2的释放量/程度进行了测量/分析。结果表明:1。当温度从35℃升高到1450℃时,生料中二氧化硫的释放量随着硫含量的增加而增加;2. 当生料中的硫含量较低时,需要较高的温度来启动二氧化硫的释放。这些结果与这样一个事实是一致的,即生料中硫含量的减少会导致其熔化和煅烧温度的显著提高,并阻止液相的形成和硫的蒸发。

Non-isothermal kinetic analysis of sewage sludge from wastewater treatment plant 污水处理厂污泥的非等温动力学分析
Ruihua Shao, P. Fang, Juan Ren, Q. Si
The thermal decomposition kinetics of sewage sludge was investigated by means of non-isothermal TG at different heating rates of 5 K·min−1, 10 K·min−1, 15 K·min−1, 20 K·min−1 and 30 K·min−1. The non-isothermal kinetic parameters and mechanical functions were analyzed by means of Flynn-Wall-Ozawa equation and Coats-Redfern equation. Before and after DTG peak, Flynn-Wall-Ozawa and Coats-Redfern were used to determine the kinetic parameters. Before and after DTG peak, Eα→0=102.17 kJ·mol−1, 88.17 kJ·mol−1 respectively. Before DTG peak, the most probable kinetic function was No.3 G-B Equation, and the corresponding mechanism was controlled by Three-Dimensional Diffusion (cylindrical symmetry). The apparent activation energy and the pre-exponential constant (A) were Eβ→0=107.44KJ·mol−1, lnAβ→0=12.64 respectively. After DTG peak, the most probable kinetic function was No.13 Avrami-Erofeev Equation (n=4), and the corresponding mechanism was controlled by random nuclear producing and growing process. The apparent activation energy and the pre-exponential constant (A) were Eβ→0=88.34 KJ·mol−1, lnAβ→0=14.25 respectively.

The non-isothermal kinetic parameters and mechanical functions were analyzed by means of Flynn-Wall-Ozawa equation and Coats-Redfern equation. Before and after DTG peak, Flynn-Wall-Ozawa and Coats-Redfern were used to determine the kinetic parameters. Before and after DTG peak, E<inf>α→0</inf>=102.17 kJ·mol<sup>−1</sup>, 88.17 kJ·mol<sup>−1</sup> respectively. Before DTG peak, the most probable kinetic function was No.3 G-B Equation, and the corresponding mechanism was controlled by Three-Dimensional Diffusion (cylindrical symmetry). The apparent activation energy and the pre-exponential constant (A) were E<inf>β→0</inf>=107.44KJ·mol<sup>−1</sup>, lnA<inf>β→0</inf>=12.64 respectively. After DTG peak, the most probable kinetic function was No.13 Avrami-Erofeev Equation (n=4), and the corresponding mechanism was controlled by random nuclear producing and growing process. The apparent activation energy and the pre-exponential constant (A) were E<inf>β→0</inf>=88.34 KJ·mol<sup>−1</sup>, lnA<inf>β→0</inf>=14.25 respectively.","PeriodicalId":6296,"journal":{"name":"2011 International Conference on Remote Sensing, Environment and Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73462081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
