摘　　要：为保障三峡水库生态环境良性循环和库区内的用水安全,在库区内的各污染点源建立近红外光谱分析监测点,实时快速检测排放废水的污染物耗氧量(Total Oxygen Demand,TOD)这项综合指标,有助于实时监测污染防治和污染突发的应急性快速检测。近红外光谱分析方法优势在于实时检测,快速简便,同时可以推定化学需等量(Chemical Oxygen Demand,COD)、生化需氧量(Biochemical Oxygen Demand,BOD)和总有机碳(Tofal Organic Carbon,TOC),结果可信可靠。随着这个方法的研究推广,将弥补原有的其他方法的繁杂预处理、耗时周期长、程序繁琐等弱点。将会给环境安全和实时监控带来实际的经济效益。To ensure the benign circulation of ecological environment and water quality in the Three Gorges Res-ervoir area, several monitoring sites were set up, and the TOD index was measured with near infrared spectrumanalysis for the point source waste-water pollution of the reservoir area. The observations are helpful for the es-tablishment of capability for real-time and rapid monitoring of the pollutions, especially for emergency diagnosisand management. In addition, the NIR spectrum analysis can also simultaneously measure other indices such asCOD, BOD and TOC etc., and the results are reliable. In comparison with other methods, the NIR measurementscan avoid some weaknesses, such as tedious pretreatments with long time period and complicated procedures,and it will benefit environment security and monitoring for the pollutions.
