摘要
利用现场动态实验对影响吹脱塔除污染的因素进行了实验研究 ,确定最佳气水比为 5∶ 1、淋水密度为 1 0 .0 m3/( m2 · h) ;在最佳运行状况下 ,吹脱法对地下水中油类物质的去除率可达 50 %左右 ,还能去除水中的 NH3- N、高锰酸钾指数等污染物质 ,是一种非常有效的预处理方法 .同时采用色 -质联机方法 ,分析了吹脱单元进出水中有机物质组分的变化 ,并探讨了去除油类有机物质的机理 .
The tests on factors which influencing air stripping tower to remove polluteants were carried out.According to field situation optimum air to water ratio is 5∶1 and liquid loading rate is 10 m3/(m2·h).The experimental results also show that air stripping not only can remove more than 50% total oil in the groundwater,but also can remove pollutants such as amino nitrogen,potassium permanganate index in the groundwater.Air stripping is an effective preliminary method at the oil treatment.The varieties of the organic was analyzed in the influent and effluent of the air stripping tower by using GS/MS,and the removal mechanism of petroleum pollutants is discussed.
