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。     

尼尔基水利枢纽施工干扰区生态环境修复与景观规划设计

大型水利工程的建设无疑为人们的生产生活带来了安全与保障,但其施工对生态环境的破坏同样不可小觑。本文结合尼尔基水利枢纽施工干扰区的实际情况,探讨水利枢纽施工干扰区生态环境修复与景观规划设计的理念与指导思想,从植物选择、水体处理与分区设计3个方面介绍了尼尔基水利枢纽施工干扰区生态环境修复与景观规划设计的主体方案构思。     

底层设有商业服务网点的高层居民住宅楼 消防安全问题研究

高层建筑已经成为城市建筑中最主要的建筑形式,底层设有商业服务网点的高层居民住宅楼由于兼具商业和居住的功能而受到开发商和用户的青睐。由于对底层商业服务网点的使用需求不同进行的改建、扩建带来的较为突出的消防安全问题,给城市的消防安全管理增加了不确定因素。采用数值模拟的方法构建了底层商业服务网点改扩建后的火灾场景,研究了此类场所改扩建后的火灾危险性,对增设自动喷水灭火系统的消防设计方法可行性进行了论证。模拟结果显示,仅在改扩建网点增设自动喷水灭火系统可以达到阻止火灾蔓延并扑灭火灾的安全要求。     

Bordeaux: urban renovation,conservation and rehabilitation

Over the past thirty years Bordeaux's politicians and planners have played critical roles in both changing and conserving the inner environments of one of France's most attractive provincial cities. A succession of urban policies has been implemented to attempt to halt depopulation, economic decline and environmental degradation in the inner city. These policies reflect changing emphasis in national planning for urban areas and have ranged from slum clearance and total renovation in the Mériadeck district, to a recent more socially aware set of approaches that attempt to rehabilitate inner‐city housing and promote neighbourhood well‐being in the district of Saint Michel. Investment in architectural conservation continues apace and both private and public capital is being directed to improving housing stock in the inner city. Attempts to revitalise economic activities have achieved modest success but more socially orientated policies prove difficult to implement.     

Gentrification and housing improvement: the case of Nürnberg

A revival of interest among professional people in central and inner city residence appears to have occurred in West Germany since the late 1970s. In recent years, a selective programme of central area rehabilitation has successfully wedded public and private funding in Nürnberg, with consequent displacement of low‐income tenants. The further spread of upgrading and social change appears to have been halted in parts of the inner city designated as Urban Renewal Areas, where the federal and local authorities are apparently intent on stabilising and improving the much‐neglected housing and environmental conditions of the poorest “guestworker” communities.     

南京市内金川河治理对策和成效分析

自2015年起,南京市为贯彻落实国务院"水十条"行动计划,逐步开展和推进消除城市建成区黑臭水体整治行动,本文基于笔者近年参与的南京市黑臭河道整治工作,以南京市内金川河治理为例,首先介绍该区域水系现状,然后阐述了治理思路及对策,最后进行成效分析,为其他城市的河道水环境整治提供了一种借鉴。
