炼油污水深度处理回用工艺实验研究

试验工艺流程的方案选定,充分吸收了各炼油厂进行的污水深度处理的成功试验经验,以原臭氧生物活性炭工艺单元为基础,提出了以混凝气浮与臭氧生物活性炭串联工艺为核心的总体工艺流程,以降低工程投资及处理成本,提高污水回用的经济效益;同时,指出试验过程中所存在的问题及其对策。因此,开展炼油污水深度处理回用工艺试验研究,必将为炼油污水深度处理提供强有力的技术支撑,可作为相关污水回用处理工艺选择的参考。     

如何应对发达国家的环境保护壁垒

20世纪90年代以来,环境保护已成为世界各国政府关注的首要问题之一.出于保护本国消费者生命健康和生态环境的考虑,发达国家纷纷把环境保护壁垒作为其贸易壁垒的主要组成部分.我国作为世界上最大的发展中国家,近年来在对美国等发达国家的贸易中保持了较大的顺差,且出口产品多为劳动密集型产品,因此受到发达国家环境保护壁垒的限制也较严重.从政府和企业两方面入手,讨论我国应如何应对发达国家的环境保护壁垒.     

城市光污染侵害案件法律适用问题的探讨

在城市光污染侵害案件日益增多的同时,我国光污染侵害的法律救济手段和救济结果却不尽人意。虽然我国在宪法、环境保护法等法律、法规及民法中都有处理光污染侵害案件的法律依据,但由于缺少直接的规定,使环境保护法律体系存在太大的缺陷。因此,亟待制定有关的标准和修改相关的法律,从而更好地防治光污染,维护受害人的合法权益。     

工业设施受恐怖袭击风险评价方法研究进展

鉴于全球范围恐怖活动日益猖獗的形势,无论从学术研究还是维护社会安全稳定的角度,恐怖袭击都应作为一个重要的风险因素加以深入研究.恐怖袭击事故是由恐怖分子策划和实施的,其风险机理不同于系统失效或人为失误造成的事故机理.科学地分析、预测和预防恐怖袭击的风险成为当前安全科学领域面临的新课题.本文对国内外相关研究的进展做了较详细的评述,提出了对重要工业设施和公共设施在加强传统安全管理的同时要加强脆弱性评价和保安管理体系建设等建议.     

Facile Preparation of Chitosan Films for High Performance Removal of Reactive Blue 19 Dye from Aqueous Solution

This study aimed at finding effective strategies for high-performance removal of reactive blue 19 (RB19) dye from aqueous solution. Chitosan (CS) films had been prepared by using solvent casting with mild drying for this purpose. The CS films were characterized by X-ray diffraction, field-emission scanning electron microscopy, and Fourier transform infrared (FTIR) spectroscopy. The performance of RB19 removal using CS were evaluated by varying contact time, solution pH, initial dye concentration, and adsorbent dosage. Adsorption isotherms, kinetics, and desorption were investigated by batch experiments. Results showed that CS films exhibited the optimal adsorption performance for RB19 removal and high maximum adsorption capacities of RB19, which were 799 and 822.4 mg g^?1 at 20 and 40 °C, respectively. Adsorption kinetic data were well described by the pseudo-second-order kinetic model. FTIR analyses further indicated that interactions between RB19 and the CS film occurred during adsorption. The CS films also exhibited satisfactory desorption of RB19 at about 80 % after 30 min of desorption at pH 11. Our study demonstrated that the CS films can be easily prepared and applied for effective removal of RB19 in treatment of wastewater.     

Report on the fifth meeting of INRA’s national network of ecotoxicologists,ECOTOX

The fifth meeting of INRA’s national network of ecotoxicologists took place on 25 to 27 November 2014 in Biarritz, France. The main aim of the meeting was to bring together ecotoxicologists from INRA and associated partners, providing them ample opportunity to share and discuss their latest scientific results as well as the national policy of research in ecotoxicology and to precise perspectives for the network.
