我国城市降雨径流污染控制模式探讨

随着城市的发展与点源污染控制的不断完善,城市降雨径流污染日益突出,对城市水体构成严重威胁,必须得到有效的控制。对国内外城市降雨径流污染控制模式进行了比较,并结合我国的实际情况,首次提出了双重控制模式,以期为我国城市降雨径流污染的控制与决策提供参考和借鉴。     

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.

环境污染纠纷技术仲裁监测方法探讨

以某铝厂环境空气氟化物污染纠纷的技术仲裁监测为实例，总结出了一套环境污染纠纷技术仲裁监测的工作程序和方法，从法律程序、技术路线、质量保证，监测指标体系等方面对环境污染纠纷技术仲裁监测工作如何开展进行了探讨。     

东太湖渔业发展对水环境的影响及其生态对策

东太湖网围养殖始于1984．至今养殖面积达3200hm^2。占东太湖面积的24％以上。网围养殖的盲目发展带来了湖泊的水质污染．沼泽化等环境问题。为保护东太湖水域环境。必须明确湖泊功能定位。减少湖泊污染源。并在此基础上进行人工调控．合理放养。完善湖泊生态系统结构。针对东太湖水生植被退化的趋势。应恢复和加强对优质水生植被的保护。促进湖泊生物多样性。恢复其良性生态。     

滇池草海蓝藻清除应急措施总体方案

我国首例大型湖泊蓝藻清除工程中，制订了由湖泊应急治理措施、水资源应急调控措施和行政管理强化措施构成的注重时空需要、突出治标应急和多专业、多技术相互配合的综合应急方案。     

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）。

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
