废旧锂离子电池回收利用的研究现状

目前废旧锂离子电池的回收利用，重点是电极材料中有价金属的回收，主要是应用酸浸和溶剂萃取相联合的湿法冶金技术，其次将电化学技术用于浸出液中金属的沉积和对失效电极材料的直接修复也有相关的研究报导。根据锂离子电池的发展和未来的环境要求，今后的回收利用将朝综合处理和多元化处理技术的方向发展。

天津市环境空气SO2污染现状及分析

天津环境空气SO2的年均浓度始终超过国家二级标准。年均浓度超标主要因为采暖期SO2浓度过高所至，采暖期SO2平均浓度是非采暖期浓度的3倍左右；在2002--2005年的三个采暖期里，SO2污染逐年加重，导致了年均SO2浓度的逐年升高。天津SO2污染与采暖期增多的低烟囱排放、不利的气象条件有关，也与流动源的隐性排放、能源利用效率低下有关。结合天津经济发展速度、每年煤耗增量、现有环境治理手段来做预测，空气SO2浓度要在未来几年内达到国家二级标准仍是不可能的。     

生活污水回用作循环冷却水补充水处理方案的研究

分析了自来水及经膜生物反应器处理后的生活污水的水质指标，计算了水质判断指数，结果表明两者均为腐蚀性水质。通过静态缓蚀实验筛选合理的药剂，结果表明HEDP，ATMP，PBTCA的最高缓蚀率均高达90％以匕，HEDP，PBTCA与Zn^2＋复配的协同效果较好，复配后最高缓蚀率提高到98％以上。研究了考虑阻垢问题时的水处理药剂配方，通过正交试验筛选出最佳药剂浓度配方为：T-325：PBTCA：Zn^2＋=8：4：3。

Study of Pollution of the Plitvice Lakes by Water and Sediment Analyses

The process of eutrophication in form of intense plant growth has been observed in some lakes and water streams at the Plitvice Lakes National Park in central Croatia. Here we investigate whether this phenomenon is a consequence of anthropogenic pollution or due to naturally produced organic matter in the lakes. We applied chemical analysis of water at two springs and four lakes (nutrients, dissolved organic carbon (DOC), trace elements) and measurements of surface lake sediments (mineral and organic fraction analyses, trace elements) in four different lakes/five sites. The chemical composition of water does not indicate recent anthropogenic pollution of water because the concentrations of most trace elements are below detection limits. The concentrations of DOC and nutrients are slightly higher in the area of increased eutrophication-plant growth. Also the content of organic matter in the sediment is at the highest level in areas with highest C/N ratio indicating that the organic fraction of this sediment is mainly of terrestrial origin. There is no significant difference among the trace element concentration in the upper segment of all cores, deposited approximately during last 50 years when higher anthropogenic influence is expected due to development and touristic activity, and the lower part of the cores, corresponding to the period approximately 100–200 years before present. The content of trace elements and organic matter in sediments decreases from the uppermost lake downstream. According to our results there is no indication of recent anthropogenic pollution in water and sediment. Higher concentrations of DOC in water as well as phosphorus and some other elements in the lake sediment can be a consequence of input of natural organic matter to the lake water.     

基于无线传感物联网技术的泥石流造成道路中断概率评估

为减少泥石流中断道路对人类生命财产的危害，该文提出基于无线传感物联网技术的泥石流中断道路概率评估方法。首先构建包括感知层、传输层、数据层与应用层的物联网技术泥石流中断道路评估系统，然后通过分析泥石流中断道路的影响因素，选取出评估泥石流中断道路概率的指标并创建评估指标体系，对评估指标实行分级，最后以灰色关联度分析法确定指标权重，采用因素叠加法创建评估模型实现评估概率等级划分。实例分析结果表明:此方法可准确、有效评估汶川县的5条道路的泥石流中断道路概率，其中道路a概率较高，道路e的概率较低，其余三条道路的概率中等；且此方法具备数据采集时耗时短、效率高优势；可为及时治理泥石流灾害、规避道路中断风险提供有效依据。
