渣油－水乳化液作为路面抑尘剂的研究

为了有效抑制汽车运输路面的扬尘，选择低浓度渣油－水乳化液作为抑尘剂，通过在实验室大量的试验，掌握了一组渣油乳化的最佳配方及其制备工艺，即渣油３％－６％，乳化剂约０．５％，水９３．５％－９６．５％，制备温度＞７０℃．经过室内和现场大规模试验表明，当路面喷洒量达到２．２ｋｇ／ｍ２时，其有效抑生时间达到１０ｄ以上，并且在一定程度起到养路的作用，长期使用可取得显著的综合经济效益．     

不同生物接触氧化方法对藻类的去除效果比较及其途径分析

比较了3种生物接触氧化法对富营养化水源水中藻类的去除效果，探讨其去除藻类的途径。试验结果表明：淹没式曝气生物陶粒滤池（I型）在4-6m/h过滤速度条件下，对藻类总数的去除效率稳定，平均为70%左右；采用YDT弹性立体填料的中心导流筒曝气生物接触氧化法（Ⅱ型）与直接微孔曝气生物接触氧化法（Ⅲ型），在试验初期对藻类总数的去除率较低，平均去除率分别为60.2%、51.6%。但随着生物膜厚度的增加，试验后期对藻类的去除效果逐步得到提高，平均达70%以上。生物膜对藻类的生物絮凝、吸附、生物膜的脱落沉降等是生物接触氧化法去除藻类的主要途径。

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.

铁路专用线声环境影响评价

针对新建铁路专用线沿线的环境特征，提出了铁路专用线声环境影响评价的程序、内容和方法。在目前缺乏新建铁路噪声预测模式的情况下，提出了应对铁路边界噪声、不同距离处的铁路噪声、敏感点噪声、鸣笛噪声进行预测，并以某铁路专用线声环境影响评价为例，对上述四种噪声进行了预测，通过预测得到铁路两侧的声环境状况，并以此为依据提出了铁路噪声的防治对策，以保证铁路专用线沿线声环境质量。

Connecting sources, fractions and algal availability of sediment phosphorus in shallow lakes: An approach to the criteria for sediment phosphorus concentrations

Although point and nonpoint sources contribute roughly equal nutrient loads to lakes, their relative role in supporting algae growth has not been clarified. In this research, we have established a quantitative relationship between algae-available phosphorus (P) and P chemical fractions in sediments; the latter indicates the relative contribution of point versus nonpoint sources. Surface sediments from three large shallow lakes in eastern China, namely, the Chaohu, Taihu and Hongzehu Lakes, were sampled to assess their algae-available P and chemically extracted P fractions. The algae-available P primarily comes from iron/aluminium (hydr)oxide-bound P (Fe/Al-bound P), 45% of which is algae-available P. The ratio of Fe/Al-bound P to calcium compound-bound P (Ca-bound P) indicated the relative contribution of point to nonpoint sources, with the point sources contributing the majority of increased Fe/Al-bound P in sediments. Therefore, the reduction of point sources from urbanized areas, rather than nonpoint sources from agricultural areas that primarily contribute to the Ca-bound P fraction, should be prioritized to alleviate cyanobacterial algal blooms (CyanoHABs) in shallow lakes with sediment P as a potential source to support algae growth. With these important results, we proposed a conceptual model for “P-pumping suction” from sediments to algae to aid in the development of the criteria for sediment P concentrations in shallow lakes.     

关于环境教育的思考

目前，我国专业环境教育毕业生供需基本平衡，但有专业设置过繁之弊；中小学环境教育处实验阶段，尚未普及；社会环境教育滞后则多由经济和文化落后所致。必须针对存在问题，借鉴国外成功经验，办好中国的环境教育。
