完善、合理、科学的城市排水系统关系到市民的切身利益和城市的安全,关系到城市生态环境改善和可持续发展,建立良好的城市排水系统是解决中国水资源短缺和水环境恶化问题的优化途径。随着中国国民经济的高速发展,城市化进程不断加快,大多数城市陈旧的排水系统已经不适应发展要求。在此以杭州城市排水系统作为背景,针对目前的运行管理模式进行分析,期待能够为其他城市排水管理者提供一些帮助与建议。 相似文献

城市污水收集处理在保障公共卫生与健康等方面发挥着重要作用。近期有研究指出,城市排水系统和污水处理厂在运行过程中会直接或间接地产生温室气体排放。如何精准地监测评估城市排水系统与污水处理厂的碳排放水平,从而科学地提出污水治理碳减排路径与碳中和模式,是城市水污染控制协同实现"碳达峰、碳中和"目标的关键突破口,也是当前环境领域的科技前沿和重点。结合文献调研和前期研究基础,以城市排水系统和污水处理厂为主要对象,总结当前温室气体排放监测与量化评估的研究现状,并探讨影响碳排放监测评估技术发展的关键瓶颈问题,提出碳减排路径构建的科学思路,为研发新一代城市污水收集与处理系统碳排放监测评估技术提供建议路线。 相似文献

针对当前城市污水处理厂进水浓度偏低,进而影响其污水处理潜力发挥和经济效益等问题,以昆明市为例,构建了基于系统动力学的城市排水系统模拟仿真模型.依据昆明市“十三五”规划目标,以2015年为基准年,设计4种减排情景,模拟预测了不同时期下不同情景的污水处理厂减排潜力及费用效益.结果表明:城市排水管网改造与强化管理对提高污水处理厂运行效率,充分挖掘其污水处理潜力至关重要,该情景近期与远期污水处理厂COD削减量较基准情景分别提高了314772,389126t;NH3-N削减量较基准情景分别提高24223,27234t;费效比较基准情景分别降低0.2和0.17,污水处理潜力得到充分挖掘,经济效益明显改善. 相似文献

在城市排水许可中,切实保护污水处理厂的权利,不但是依法行政的必然要求,而且对于保障污水处理厂的正常运行,防治水污染意义重大。文章从界定污水处理厂在城市排水许可中的法律主体资格入手,论证其作为城市排水许可行政相关人的合理性与正当性;继而深入分析污水处理厂的权利体系;在阐述污水处理厂权利保护的理论根基和现实意义的基础上,从立法完善、行政制度和司法保护等三方面提出城市排水许可中污水处理厂权利保护的应对之策。 相似文献

子汇水区的划分对SWMM模拟结果的影响研究 总被引:5,自引:0,他引:5
利用SWMM模型可以对城市排水系统进行动态模拟,可以辅助解决与城市排水系统相关的水量与水质问题.在使用SWMM进行模拟时,子汇水区划分方式和子汇水区之间流经路径的不同,将对模拟结果的时间过程曲线有很大的影响.本文主要分析在进行子汇水区划分时,考虑汇水区地形数据空间分布不均匀性,子汇水区划分的细致程度以及之间的流经路径对模拟结果中坡面径流总量、坡面径流量峰值以及峰值出现的时间产生的影响.并在此基础上,以简化SWMM输入数据并保证模拟结果的精度为原则,对子汇水区的合理划分程度进行了探讨. 相似文献

This paper reviews the tools and methodologies used for incorporating sustainability considerations into the design of mineral processing operations. It was found that while there is a range of tools and methodologies that contribute to Design for Sustainability, there is no consistent, integrated approach to support the mineral industry in incorporating a greater level of sustainability into the design process. This paper identifies the required elements in such an approach and discusses the ways in which its development would progress the industry towards sustainability. 相似文献

Solutions to the economic and environmental impacts of the automotive industry have largely focused on technological innovation at the level of products or processes. This paper argues that, in order to achieve sustainability, change processes must be undertaken at the functional and systemic level.The concept of product-service systems (PSS) represents a valuable opportunity to introduce such changes. PSS is predicated on new forms of product ownership, stewardship, design and producer–consumer interaction. The challenge now is to investigate ways in which the PSS concept might be introduced at the empirical level.The paper suggests that the adoption of micro-factory retailing (MFR) ideas offer a means of introducing such a system-level change in the automotive industry. MFR is based on novel approaches to vehicle design that facilitate the economic viability of small-scale localised manufacturing sites. It is argued that such an approach to vehicle production, allows the adoption of a full scale PSS at local levels. Furthermore, via aspects such as the unification of the commerce and manufacturing function, and the proximity of manufacturing and servicing sites to users, the MFR approach may also offer distinct advantages compared with prevailing visions of PSS. 相似文献

This paper summarises the contributions made to the special issue on The automobile Industry & Sustainability. Taking a life-cycle perspective, the contributions are allocated into the automotive life-cycle phases of design, manufacture (and supply chain management), use, and disposal or ‘end of life vehicle’ management. The contributions are also set into the broader context of research into the global automotive industry, and the economic, social and environmental pressures confronting the industry. In doing so, this introductory paper provides a brief assessment of the ways in which the papers in the special issue have furthered our understanding of the difficulty in achieving a sustainable automotive industry, and some of the measures that might be taken as progress towards that difficult goal. 相似文献

Acid Mine Drainage (AMD): causes,treatment and case studies 总被引:1,自引:0,他引:1
《Journal of Cleaner Production》2006,14(12-13):1139-1145
This paper describes Acid Mine Drainage (AMD) generation and its associated technical issues. As AMD is recognized as one of the more serious environmental problems in the mining industry, its causes, prediction and treatment have become the focus of a number of research initiatives commissioned by governments, the mining industry, universities and research establishments, with additional inputs from the general public and environmental groups. In industry, contamination from AMD is associated with construction, civil engineering mining and quarrying activities. Its environmental impact, however, can be minimized at three basic levels: through primary prevention of the acid-generating process; secondary control, which involves deployment of acid drainage migration prevention measures; and tertiary control, or the collection and treatment of effluent. 相似文献
