滇池水环境污染的工程治理综述

滇池污染治理工作已经进行了20多年，各级政府实施了60个治理项目，投资了几十个亿，但至今滇池水质改观并不明显。这主要是由于近年来滇池流域的社会经济发展迅速，城市及经济规模的急剧扩大，各种污水及固体废弃物的产生量也急剧增加。加上滇池地处盆地最低点，污染物基本上都随水流入滇池。而滇池所处地域地貌条件，决定了其径流面积小，水资源量少，蒸发量大，使滇池富营养化及生态恶化问题日趋严重，使滇池处于严重污染与水资源短缺的双重困难之中。滇池污染治理面临十分严峻的形势，需要在加大污染治理力度的同时，采取更直接有效的措施－－通过建设主城区截污工程和外流域引水工程，来改善滇池水环境质量，加快污染治理进程。
