电解法处理高含硫气田水

本文详细介绍了川南矿区含硫气田水电解法处理的试验情况，用自己研制的电解反应器对电解时间、pH值、电流密度等工艺条件进行了考察，提出了电解法处理含S~(2-)200mg／L的气田水的最佳工艺条件。试验结果表明：该方法是成功的，它可以使气田水中硫化物的脱除率达99％以上，达到国家排放标准（GB8978—88：S~(2-)＜5mg／L）。该方法的主要特点是投加处理药剂少，操作简便，设备小型，占地面积小，特别适用于产水量不大的井站使用。     

全息理论与灾害周期性

利用煮茧废水培养钝顶螺旋藻的初步研究

本文对缫丝厂煮茧废水和Ｚａｒｒｒｏｕｋ培养基的主要营养成份进行了分析比较，筛选出了适合钝顶螺旋藻（Ｓｐｉｒｕｌｉｎａｐｌａｔｅｎｓｉｓ）在煮茧废水中生长繁殖的培养基和与之相适应的驯化藻种。经室外１５０升煮茧废水扩大培养，干藻生物量可达１６．０３克／米￣２·天，粗蛋白含量达５８．６％，含有１７种氨基酸。比用Ｚａｒｒｏｕｋ培养基培养的螺旋藻产量提高１５．７８％，成本减少８０％以上。培养后的煮茧废水ＣＯＤ和ＢＯＤ＿５浓度低于我国污水综合排放标准。研究结果表明：采用本实验室筛选的煮茧废水培养基和驯化藻种，在煮茧废水中大量培养螺旋藻，实现废水资源化是可行的，具有明显的经济效益和环境效益。     

Flood area and damage estimation in Zhejiang,China

A GIS-based method to estimate flood area and damage is presented in this paper, which is oriented to developing countries like China, where labor is readily available for GIS data collecting, and tools such as, HEC-GeoRAS might not be readily available. At present local authorities in developing countries are often not predisposed to pay for commercial GIS platforms. To calculate flood area, two cases, non-source flood and source flood, are distinguished and a seed-spread algorithm suitable for source-flooding is described. The flood damage estimation is calculated in raster format by overlaying the flood area range with thematic maps and relating this to other socioeconomic data. Several measures used to improve the geometric accuracy and computing efficiency are presented. The management issues related to the application of this method, including the cost-effectiveness of approximate method in practice and supplementing two technical lines (self-programming and adopting commercial GIS software) to each other, are also discussed. The applications show that this approach has practical significance to flood fighting and control in developing countries like China.     

INVESTIGATION OF TURBIDITY MAXIMUM IN A MESOTIDAL ESTUARY,TAIWAN1

ABSTRACT: To comprehend the distributions of salinity, temperature, and suspended sediment in the Danshuei River estuary in Taiwan, monthly field surveys were conducted in 2003. These included several high and low slackwater surveys and intensive surveys. The results show that the Danshuei River estuary is predominately a partially mixed estuary. The highest concentration of suspended sediment is typically observed at the Chung‐Hsin Bridge, the most upstream sampling station. The suspended sediment concentration exhibits a general decreasing trend in the downstream direction. It may be concluded that the sediments mostly come from the upstream reach. A locally high concentration of suspended sediment is found at the Kuan‐Du station because of the local deep channel bathymetry and two‐layered estuarine circulation. A vertical two‐dimensional hydrodynamic and sediment transport model is applied to investigate the tidally averaged salinity distribution, residual circulation, and suspended sediment concentration. The modeling results reveal that, under the Q₇₅ flow condition (i.e., low flow), a turbidity maximum occurs at the Kuan‐Du station due to the strong estuarine circulation. The model simulation with a much higher river flow condition results in a weaker residual circulation and weaker turbidity maximum.

树脂吸附法处理对硝基苯乙酮生产废水

采用AM-1吸附树脂和ND-900络合树脂对硝基苯乙酮生产废水进行吸附处理，试验结果表明，使用2种树脂串联的处理效果优于单独使用某一种树脂，而且ND-900络合树脂在前，AM-1吸附树脂在后串联处理的效果最好，废水体积为30BV时，COD去除率为92.8%；脱色率为100%，出水由原废水的橙红色变为无色，采用质量分数为8%的NaOH溶液作为脱附剂，脱附效果良好。
