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.

滇池水污染总量控制中污染源系统特征研究

湖泊流域同入湖水系的流域单元组成，本文以滇池流域单元为基础，进行了污染源总量控制片区划分，并对各片区进行了污染源系统特征研究，从而为滇池主要污染物总量控制提出了工作重点和具体对象。     

沈阳张士污灌区镉循环的分室模型与污染防治对策研究

对沈阳张士污灌区大气、水、土壤和生物各分室中Ｃｄ的库存量和各分室间Ｃｄ的循环通量进行了研究，建立了土壤－水稻系统中Ｃｄ流分室模型。该模型表明，Ⅱ闸和Ⅲ闸地区土壤分室中Ｃｄ的库存增量均为正值。可见，该污灌区近年来Ｃｄ污染程度由于污水灌溉仍然处于加剧的趋势。研究最后指出，该污灌区Ｃｄ的污染防治对策主要是减少污水灌溉量、进一步降低灌溉水中Ｃｄ的浓度和通过富Ｃｄ植物收获带走Ｃｄ．其中，以野生苋的收获带走Ｃｄ最有意义，它可使Ⅱ闸和Ⅲ闸地区Ｃｄ的下降速率分别依次达到２９．４９和２２．８１ｍｇ／（ｍ￣２·ａ）。
