Oil stain online monitoring method and device based on hydrophobic oil absorption material

Abstract

The invention relates to an oil stain online monitoring method based on a hydrophobic oil absorption material. The method comprises the following steps that (1) oil stain types are changed to obtain atime-varying curve of signal values of different oil stains under the condition of different use amounts, wherein different oil stains have different signal value change slopes in the adsorption stage; (2) the temperature is changed, and a time-varying curve of fluorescence signal values of different oil stains at different temperatures under different dosage conditions is obtained according to the method in the step (1); (3) the change of the signal value is monitored in the hydrophobic material on line, a time-varying curve of the signal value is drawn, after equal signal value stabilization, the signal value is compared with V0, if the signal value changes, oil contamination exists, the oil contamination category is determined according to the signal value change slope of the absorption initial stage at the temperature, and then the measured signal value change curve is matched with the determined time-varying curve of the signal values of the oil contamination at different dosagesat the temperature to determine the content of the oil contamination. The invention further comprises a device for implementing the online oil stain monitoring method.

Description

technical field [0001] The invention belongs to the field of water body oil spill monitoring, in particular to an oil pollution online monitoring method and a device thereof. Background technique [0002] The ocean area accounts for about 71% of the total area of ​​the earth, and it contains a large amount of oil resources. Since the 20th century, the world's economy and technology have achieved unprecedented development, and human beings have increasingly exploited and utilized the ocean. Offshore oil exploration and transportation With continuous development, the ensuing marine oil spill pollution problem has become more and more serious, causing immeasurable damage to the marine environment, and the form is very serious. [0003] The common and traditional marine oil spill monitoring methods include gravimetric method, suspension method and ultraviolet absorption method. However, these methods all need to be extracted, the operation is complicated, and the on-line measur...

AI Technical Summary

Problems solved by technology

However, the remote sensing optical monitoring method is used for oil pollution monitoring, and the monitoring period is long, and the initial oil spill accident may not be discovered in time

The advantage of the dissolved oxygen monitoring method is that it can quickly monitor oil spill pollution, but because the monitoring factor oxygen content is greatly affected by the environment, the accuracy is not very high
