A／O-MBR工艺处理校园生活污水中水回用工程的设计与运行

针对Et处理量为1500m3的高校中水处理设施,论述了缺氧／好氧-MBR（A／O—MBR）处理工艺运行特性,完成了长效监测及经济性评价。系统MBR池污泥浓度（MLSS）控制在8～12g／L,缺氧池和好氧池水力停留时间（HRT）分别为3h和7h,污泥回流比为200％～300％。当进水COD、总氮、氨氮平均浓度分别为481．3、75．1和65．8mg／L时,出水COD、总氮、氨氮平均浓度分别为16．5、13．4和0．7mg／L,平均去除率分别为96．4％、81．9％和99．0％。在进行化学除磷的情况下,出水总磷的平均浓度为0．8mg／L,平均去除率86．5％。出水水质优于《城市污水再生利用城市杂用水水质》（GB／T18920—2002）中的相应水质指标要求。经济性分析结果显示,该中水站的电耗为0．58kWh／m3。     

构建防灾科技学院和谐校园

高等学校是文化、知识和人才的聚集地,我院作为培养德、智、体、美全面发展的防震减灾专业人才的摇篮,是构建社会主义和谐社会的前沿阵地.构建和谐校园是时代社会发展的需要,是摆在各级领导和全体师生员工面前的一个重大问题.文章认为,构建和谐校园应从思想认识、运行机制、校园文化建设、管理创新等方面着手进行.

Stratification and Tidal Current Effects on Larval Transport in the Eastern English Channel: Observations and 3D Modeling

We study how the combination of tides and freshwater buoyancy affects the marine organisms accumulation and horizontal transport in the ROFI system of the eastern English Channel. The Princeton Ocean Model coupled with a particle-tracking module is used to study the migration of fish eggs and larvae under different forcing conditions. Results of modeling are validated against observed concentrations of Flounder (Pleuronectes flesus) larvae. Numerical Lagrangian tracking experiments are performed with passive and active particles, representing sea-water organisms. Passive particles are neutrally buoyant whereas active particles are able to exercise light dependent vertical migrations equating to the swimming behavior of larvae. The experiments reveal that the strongest accumulation of particles occurs along the French coast on the margin of the ROFI. This happens because the interaction between the turbulence, the freshwater buoyancy input, and tidal dynamics, produces particle trapping and vertical spreading within the frontal convergence zone. Tides and freshwater input induce net alongshore horizontal transport toward the North. Tidal currents modulate the magnitude of horizontal transport whereas the fresh water input controls more the location of accumulation zones. Tracking experiments with active particles indicate that the vertical migration leads to a significant departure from the passive particle transport pattern. Differences lie in the shape of the particle transport pattern and the rate of the northward migration. In particular, vertically migrating particles travel slower. To find possible Flounder migration pathways, particles are released within the assumed spawning area of Flounder. The model predicts larvae drift routes and demonstrates that throughout the entire particle-tracking period the horizontal structure of the particle distribution is consistent with the larvae concentrations observed during the field experiments.     

"How near were we to Ruine": the effects in England of the earthquake of 8th September 1692

This paper attempts to Illustrate some of the advantages and disadvantages of using contemporary evidence in the study of historical seismicity. The event considered here is doubly significant—it was a large event by British standards, as well as arguably the best documented earthquake to have occurred before the mid-eighteenth century. At a time when an interdisciplinary approach to historical seismicity is still in its infancy this paper identifies those areas where the available sources can assist in the evaluation of early macroseismic data.

大学生健康与头发中铅含量的关系

通过实验、调查、查资料的方式，对“大学生发铅与人体健康”这一课题展开讨论。用实验法、问卷调查和社会调查、查资料3种方式进行研究，分析了铅对人体健康的影响及大学生健康与头发中铅含量的关系，提出开发应用天然产物预防铅中毒。结果均与现代医学理论相一致。在教学中开展此项研究，对于复合型人才的培养具有积极的作用。     

基于SPSS软件对大学生寝室用电安全意识的分析 ——以四川师范大学为例

为探究大学生寝室用电安全意识的现状及分析性别和年级两个变量对其的影响,本文采用问卷调查的方法对大学生进行调查。调查步骤分为预试问卷编制、预试、问卷可靠度分析、正式问卷确定和正式调查。利用SPSS24.0软件对调查结果进行独立样本t检验、单因子独立样本变异数分析(ANOVA分析)等操作,使分析结果更加科学和准确。最终得出结论:大学生寝室用电安全意识在安全认知知识方面较为深刻,在安全认知体验方面有一定的察觉能力,在安全认知监测方面还急需加强学习。另外,性别因素对安全意识有一定影响,年级因素对安全意识没有显著影响。并根据以上结论提出提了高大学生用电安全意识的对策。     

高职学生参加社区志愿活动的几点思考

高职院校大学生参加社区志愿活动具有重要的意义,有助于提高学生综合素质、增强学生社会责任感,但是其存在缺乏科学指导、缺乏持续性和学生及社区居民对其认识不足等问题。为了使高职院校学生顺利开展社区志愿服务活动,应该加强引导和管理,提高学生志愿服务意识,政府应该出台激励社区志愿活动政策,切实增强高职院校学生参加社区志愿活动的实效性。
