Ecoprofit-Styria-prepare Thirteen pollution prevention case studies in the Styrian industry

The paper focuses upon the organization of a federal state-funded pollution prevention project in the Styrian industry. The project includes 13 companies from the textile, pulp and paper, machine building, wood working and printed circuit board manufacturing industries, covering most of the sectors and sizes in the Styrian industry. It started in January 1994 and will last for one year. It will demonstrate the possibilities of pollution prevention and the need for further research work. This project will make use of the methods and tools that were refined in the Austrian Prepare project. As a first step, a systematic balance of all the inputs and outputs of a company is made, after which the weak points and inefficiencies of material and energy use are identified and the options for improvements, both economical and ecological, are defined. Consequently, modifications in products and production lead to a situation with less waste and emissions. The preliminary lessons from these projects are presented: as a rule, the utilities (consumption of process materials and water, cleaning, energy, preparatory and finishing steps) are treated as black boxes and usually represent a considerable optimization potential. In these areas especially there is usually a lack of information and coordination as well as a need for a systematic and comprehensive approach. Leadership in the company and creative consultants are needed for starting lasting successful pollution prevention projects.     

SO2和氟化物对农作物的危害的鉴别与防治

SO2 和氟化物对农作物的危害可通过症状、镜检和受害叶片的化学分析来鉴别 ,并从风向、与污染源距离、障碍物和叶片成熟程度几方面与作物病虫等影响因素相区别。排放浓度、接触时和作物本身抗性是影响危害程度的主要因素。应从治理污染、选种抗性强树木、避开作物敏感生育期、合理种植、加强施肥等方面采取措施加以防治     

反静电场处理厌氧污泥的影响因素分析

在电场和电解副效应的共同作用下，选定0．5mA、1．0mA、1．5mA和1．95mA四种电流强度作为不同的运行条件，处理时间24h，分别测定反应开始和结束时厌氧污泥上清液COD、NH4^＋-N和VSS，其变化率随电流强度呈抛物线型变化。用反静电处理厌氧污泥时，电场对污泥参数的影响存在着最佳的工作电流强度，在本试验条件下，反静电处理厌氧污泥的最佳工作电流强度为1．5mA。反静电场可提高微生物的活性，使COD与NH4^＋-N得到一定程度的降解，同时，污泥的性质影响反静电场处理污泥的效果。     

绿色化学浅议

绿色化学是更高层次的化学，其产生是为了避免或减少化学过程对人类健康和环境造成的危害，由此出现的技术是环境友好的技术。绿色化学的发展能节省资源、减少环境污染，并将成为可持续发展战略的核心内容之一。

为防震减灾事业做好科普宣传--南京地震科学馆的建设与发展

从1989年江苏省第一届科普宣传周起,南京基准地震台都被列为宣传周期间重点对外开放单位.于是,南京地震台克服重重困难,筹建了地震科学馆.十多年来在江苏省地震局和有关单位的大力支持下,由最初腾出地震台的会议室和几间办公室发展到有530平方米的展室和多功能厅,展出内容也得到丰富.同时,地震科学馆在防震减灾宣传中取得了一定的社会效益.
