摘　　要：滇池北岸入湖河流水质皆为劣V类,致使草海水质逐年恶化。依据河流所处地理区域特征提出受污染河流城内段、城郊段和河口区的不同处理技术。城内段河流适宜采用原位治理技术;城郊段可充分利用土地和鱼塘等有效处理空间:河口区宜用湿地系统加强对入湖河水的净化。截污工程是防治河流污染的最有效的方法之一,可以布设于任何河段,在适宜的条件下与其它的技术组合运用。The water quality of all the rivers in north lakeside of Dianchi lake are less than the fifth grade of national water quality standard, which lead to more and more serious water problems in Caohai lake. The different treatment technologies are pointed out to different rivers which are located at different geographic position including ur- ban rivers and suburban rivers and estuarine rivers. The in - situ treatment technology is suitable for rivers in urban areas, and land and fish pond near outskirt should be applied for rivers, and wetland system can strengthen the purification of wastewater in estuarine rivers. The Interception Project is one of the most effective ways to control fiver pollution, which can be placed at any river sections and applied with other technologies under suitable conditions.
