摘　　要：应用OilTech121便携式测油仪对某突发性水污染事件的小溪沟、长江水样进行石油类浓度检测,分析其石油类浓度沿程变化情况以及对小溪沟、长江水质的影响。结果表明,受含油废水的影响,小溪沟明显受到污染,入溪口d2石油类浓度高达24.9 mg/L,围油栏和吸油毡组成的拦截带对石油类的吸附处置效果明显,4道拦截带的油污拦截效率分别达到41%、34%、28%和18%,此外,长江水质也受到一定程度的影响,但下游水厂取水口水质未受污染,无需中断水厂取水。鉴于该仪器具有携带方便、操作简单、检测速度快等优点,并为判断拦截带吸附处置效率、水厂取水是否安全等重要决策领域提供了大量及时的第一手数据,建议在突发性水污染事件石油类浓度检测及预警中推广使用。The utility of an OilTech121 portable oil content analyzer was assessed during a sudden water pollution incident in the Yangtze River basin. Specifically,variations in oil concentrations along the receiving stream were quantified and impacts on water quality were evaluated. Results showed that the stream was obviously polluted by oil,and oil concentrations in the subcatchment d2 of the stream reached up to 24. 9 mg / L.Intercept devices consisting of oil boom and suction felts were deployed,and this equipment had obvious dissipation effects on the oil. In four interception zones,the oil interception efficiencies were estimated to be 41%,34%,28%,and 41%. In addition,while water quality was affected in the spill area and nearby waterways,the water at the downstream water intake was not contaminated. Hence,there was no need to interrupt water intake operations. With advantages including ease of transport,simple operations,fast testing capabilities,and the ability to collect a wealth of timely data for assessing the adsorption efficiency of intercept equipment,risks to water intakes,and other important decision areas,the portable oil content analyzer was found to be very useful for deployment in oil-related water pollution incidents.
