武宜运河小流域平原河网地区水环境质量现状分析及改善对策研究

文章分析了武宜运河沿线4个例行监测断面2011年至2013年水质变化情况,结果表明武宜运河水质污染情况逐年减轻.在武宜运河流域布设了42个监测断面,其中武宜运河沿程布设14个监测断面,相关河流布设28个监测断面.监测结果表明,武宜运河全线水质属于Ⅴ类~劣Ⅴ类,水质总体上表现为宜兴段稍好于武进段.相关河道水质基本属于Ⅲ类~劣Ⅴ类.目前该区域水质污染以总氮污染为主,且总氮超标最为严重.掌握了武宜运河小流域河网地区的水环境质量现状,从工业、生活、农业面源、船舶污染等方面提出了改善水环境质量的建议对策,为开展综合整治奠定了基础,对改善流域水环境具有十分重要的意义.     

Implementing SDG 15: Can large‐scale public programs help deliver biodiversity conservation,restoration and management,while assisting human development?

Among the Sustainable Development Goals (SDGs), the proposed SDG 15 promotes activities that, inter alia, “Protect, restore and promote sustainable use of terrestrial ecosystems”. An important potential contribution in achieving SDG 15 is through public programmes designed to jointly promote human development through poverty alleviation and improvement of human livelihoods and biodiversity conservation/management/restoration. An analysis of twenty public programmes with such joint objectives yielded twelve lessons learned. In addition to financial commitments, government and intergovernmental agency input for such public programmes includes ensuring political will and appropriate legal frameworks. Local communities and civil society provide input through traditional and indigenous ecological knowledge and stewardship. Appropriate shared inputs in development and the implementation of such public programmes, with communication between local community, broader civil society, the scientific community and governments will result in: better use and management of biodiversity; alleviation of poverty; security of livelihoods and better governance systems. The Ecosystem Approach of the Convention on Biological Diversity provides an ideal framework when planning and implementing new programmes. Application of the lessons learned to new public programmes will ensure that the answer to the question posed in the title is an emphatic “Yes”, and assist with the achievement of SDG 15.     

宁波月湖的水质改善与生态修复

随着浙江"五水共治"工作的深化,宁波作为浙江"五水共治"的中坚力量,始终把"五水共治"作为全市工作的首要任务和突破重点。自1999年进行清淤后,月湖水质得到短期改善,然而治标不治本的治理措施,并没有让月湖水质得到根本改善。因此,对月湖进行科学有效的生态修复,针对性地处理水污染问题,使之重新焕发活力具有十分重要的意义。     

Optimization of HSE in maintenance activities by integration of continuous improvement cycle and fuzzy multivariate approach: A gas refinery

Gas refineries have been continuously focusing on Health, Safety and Environment programs to improve maintenance activities. Several researches have studied on this area with different analysis methods. This study presents an integrated approach for optimization of factors contributing to the implementation of Health, Safety and Environment (HSE) in maintenance activities. HSE managers in each sector answered standard questionnaire whit respect to HES. The methodology is based on fuzzy data envelopment analysis (FDEA) and Deming's continuous improvement cycle. Also, this method is used to rank the relevant performance efficiencies in certain and uncertain conditions of each HSE sectors whit considering HSE in maintenance activities. It corresponds and integrates its registered HSE-MS with OHSAS 18001:2007 and ISO 14001:2004 to evaluate multiple inputs and outputs of over 36 subsidiary HSE divisions with parallel mission and objectives simultaneously. Also, it determines efficient target indices and could assure continuous improvement in the organization. This is the first study that introduces an integrated approach to improve HSE management programs in a gas refinery by a robust and continuous improvement approach.

城市分散式粪便颗粒化有机肥用作叶菜肥的肥力及环境影响

城市分散式粪便的处理已经成为现代化城市管理的一个难题.本研究在将城市分散式粪便经收集、除渣、絮凝脱水后制成颗粒肥;通过盆栽小青菜试验,评价了不同施肥量对小青菜的增产效果以及对土壤、淋溶水性质的影响,探讨了颗粒肥用于叶菜施肥的可行性.结果表明,施用颗粒肥可显著提高小青菜产量,试验条件下未对小青菜叶片造成大肠杆菌、大肠菌群等病原菌污染;在适当比例的施肥水平下,颗粒肥施用后淋溶水中的病原菌浓度低于对照组.施用颗粒肥能显著提高土壤氮、磷、钾、有机质等营养物质含量,提高土壤孔隙度水平,降低土壤容重,改善土壤理化性质;同时颗粒肥施用不会对土壤和淋溶水造成重金属离子污染,且能有效降低土壤氮、钾的淋溶.     

印染工业园区污水处理工程的运行及完善探讨

本文对某印染工业园区的混合废水处理装置开展了连续两年的运行调查,并对其进行了完善和提标改造的技术探讨。研究表明,污水处理装置的出水氨氮、总磷达标,BOD5、色度接近排放标准,而CODCr、SS难以达到一级排放要求。在现有工艺流程条件下对出水进行砂滤和二氧化氯强氧化能够保证出水达到一级A排放标准。
