在我国海上石油迅速发展、海洋环境保护日益严格、新《环境保护法》颁布实施(2015年1月1日起)的新形势下,海上钻完井废弃物处理处置问题日益突出,已成为发展的重要瓶颈之一。加拿大国家能源局等共同制定的《近海废物处理指南》,对于我国海上钻完井废弃物处理处置具有重要的参考借鉴意义,本文重点分析该指南的核心技术规范如钻井泥浆和钻屑等的处理处置技术。 相似文献

ABSTRACTAn under-investigated impact of urbanisation is the decrease in green spaces like domestic gardens, which does not bode well for urban sustainability. To this end, research was conducted in a suburb of Cape Town, South Africa to ascertain the degree to which residents use their garden spaces for the cultivation of edibles and to establish their management practices regarding garden waste. A mixed-methods approach determined that potential gardening space occupied, on average, about two-thirds of the area of residential plots. However, the 129 selected respondents were cultivating lawns, not food. Where the cultivation of edibles did occur, it was predominantly fruit with minimal vegetable production. The residents of the middle-class suburb had a penchant for using private gardening services who disposed of the garden waste elsewhere. Some home-composting activities were recorded. A municipal-driven composting programme will provide the impetus for increasing the rate of home composting. The study established that food production in the middle-class suburb has the potential to contribute to sustainable urban green spaces through increased home-garden cultivation. However, on-site techniques of disposing with garden waste must be promoted. 相似文献

In 1996, Thames Water launched a range of peat-free compost products based on biosolids. In order to keep up with demand and to maintain the high standards of product quality, the company has investigated higher-rate composting processes and optimisation of the maturation stage. Agitated-bay composting systems are the preferred in-vessel technology for large sludge treatment centres using woodchip as a bulking agent. These automated systems (i) accelerate the composting process, (ii) maximise throughput on a smaller footprint, and (iii) achieve better control of odour emissions.
A maturation trial with composted material from the US Filter agitated-bay system confirmed that a horticultural-grade product could be attained. Small-scale maturation trials showed that seeding with mature green waste compost can accelerate nitrification to such a rate that near zero levels of ammonia can be achieved after one month of maturation. 相似文献

国内绿色建筑的设计与实践取得了长足进步,但也存在一些问题。许多建筑过分强调绿色建筑的概念与技术,盲目追求绿色建筑的指标,反而忽视了与建筑的整合,缺乏建筑学的价值。文章通过几个项目实践,探索如何在绿色建筑作品中体现技术科学和设计文化的整合,让绿色建筑能回归到建筑设计的本源,进行了一些尝试和思考。 相似文献

建筑领域一直都是环境、能源方面的问题户,建筑能耗大、环境污染严重和可持续发展战略之间的矛盾也越来越激烈。在此背景下,我国绿色建筑水平相对比较薄弱,究其原因,关键在于绿色建筑相关政策法规的缺失。对发达国家的相关绿色建筑推动政策法规和我国相关绿色建筑政策法规进行综述,采用对比分析法对我国现行政策分别从强制性政策、激励性政策两方面分析,寻找我国绿色建筑发展过程中的政策问题,希望为今后中国绿色建筑相关政策的修改与拟定提供帮助。 相似文献
