生产型组织初始环境评审中环境因素的识别评价

环境因素的识别与评价是环境管理体系建立和实施的关键，生产型企业在初始环境评审时可以工程分析为重点，结合对正常和异常情况的分析，对生产过程和各部门涉及的环境影响进行全面分析，从而确定环境因素。在评价重要环境因素时，可先根据企业对外环境排放的接口情况、环境影响情况，结合商业方面的考虑制定重要环境因素评价准则，再利用评价准则评价出重要环境因素。     

A strategic design approach to develop sustainable product service systems: examples taken from the ‘environmentally friendly innovation’ Italian prize

The product service systems’ (PSS) sustainability potential is described in the framework of the new types of stakeholder relationships and/or partnerships, producing new convergence of economic interests, and a potential concomitant systemic resources optimization.In this perspective, it is argued that the design competencies should move towards those of the ‘strategic design’, thus introducing the concept of ‘strategic design for sustainability’: the design of an innovation strategy, shifting the business focus from designing (and selling) physical products only, to designing (and selling) a system of products and services which are jointly capable of fulfilling specific client demands, while re-orienting current unsustainable trends in production and consumption practices.Some examples of PSS are presented and discussed using the PSS categories ‘services providing added value to the product life cycle’, ‘services providing final results to customers’, and ‘services providing enabling platforms for customers’. The cases derive from an analysis of the ‘environmental friendly innovation’ yearly endowed prize submissions. The Politecnico di Milano University together with the Bocconi University and Legambiente (an environmental NGO) promotes the initiative in Italy.

Climate Change and Energy Technologies

The long time scale of the climate change problem and the inherent nature of the carbon cycle bring important implications for present technology development efforts. Even if major technology improvements are achieved for non-carbon-emitting technologies such as energy-intensity improvements, wind, solar, biomass, and nuclear over the course of the 21^st century, most examinations of potential future greenhouse emissions conclude that additional technology development will be required to stabilize greenhouse gas concentrations. The evelopment of an expanded suite of technologies including carbon capture and disposal, hydrogen systems and biotechnology hold the potential to dramatically reduce the cost of stabilizing greenhouse gas concentrations. This paper examines these technologies in the context of a global integrated assessment model of energy, agriculture, land-use, economics, and carbon cycle processes.

生物除磷机理及试验研究

介绍了生物除磷机理、生物除磷系统的积磷细菌、生物除磷所需的环境条件。SBR法除磷的试验研究表明,应用SBR活性污泥系统进行除磷,需要一定的厌氧条件;且须在厌氧阶段进行充足的曝气。试验结果证明,SBR法在时间上控制的灵活性非常适合生物除磷的环境条件。厌氧与好氧相结合,能够提高磷的去除率或降低出水磷的浓度,磷的去除率可达90%左右。
