西藏羊八井地热试验电厂地热废水污染研究
- POLLUTION OF GEOTHERMAL WASTEWATER PRODUCED BY TIBET YANGBAJING GEOTHERMAL POWER STATION
- 摘要：西藏羊八井地热试验电厂位于拉萨市西北90余公里的当雄县羊八井镇, 海拔4300 m, 该厂以地热水为动力发电.拉萨河最大的支流堆龙河(又名藏布曲)流经羊八井热田区, 既是该厂的冷却水源, 又是地热废水受纳水体, 该厂每年向堆龙河排放地热废水约2000万t;电厂排放口下有26个村庄以堆龙河水作为其生产用水和部分人畜饮用水.地热废水的排放造成了水污染, 为此, 国家投资近3000万元人民币研究和修建了该厂地热废水的全封闭回灌工程系统, 并于1994年投入使用, 但未能正常运行.本文依据监测结果, 对其未回灌而
- Abstract：The levels of As and F - in river water polluted by the discharge of geothermal wastewater produced by Tibet Yangbajing Geothermal Power Station were investigated. The results show that without treatment, the discharge causes As and F - pollution to Duilong River, the largest tributary of Lhasa Rvier. It may get even worse during the dry season. The pollution can be detected 90 km downstream from the source and the water quality of Lhasa River is effected.
