太原市地下水源挥发酚污染分析

Analysis on Underground Water Source Polluted by Volatile Phenol in Taiyuan

为了解地下水源中挥发酚的时空分布及污染原因，１９８８年１２月～１９９３年１２月对３９８眼地下水源井进行抽测，以汾河为中心，分别沿南北和东西各等间距划段，进行布点采样。研究结果表明：太原市地下水源中挥发酚污染的空间分布主要集中在汾河两岸，且以胜利桥至迎泽桥地段污染最为严重；在时间分布上并未有一个由轻至重逐渐增加的过程，而呈现突发性特点，具有不稳定性。

Underground water samples from 398 wells distributed in the east,west,north and south of Fenhe river with equal intervals respectively were detected to study the reason the time and space distribution of the volatile phenol pollution in the underground water and the reason for it's pollution during Dec.1988 to Dec.1993.The results showed that the volatile phenol pollution in the underground water sources mostly concentrated in the areas along the banks of Fenhe river.The pollution was the most serious in the areas between Shengli bridge and Yingze bridge along the river.It didn't showed a tendency that pollution deteriorated gradually with the increases of the years,but it accrued accidentally and unstably.It indicated that the main reason of the volatile phenol pollution in the underground water was directly due to surface water polluted by volatile phenol.
