Description

Technical Field

[0001] The present invention relates to the technical field of oil detection in water, and in particular to a detection device and method for detecting oil in water. Background Art

[0002] Oil pollution mainly comes from industrial wastewater discharge, ship oil leakage, oil extraction and transportation, etc. These oil substances have a serious impact on the water ecology. Oil substances can cause poisoning to aquatic organisms, plants and ecosystems, affecting water quality and biodiversity. Oil pollution of water sources will directly threaten the safety of drinking water, so monitoring oil substances in water is an important measure to protect public health. In addition, many industrial processes produce oily wastewater, such as petrochemicals, food processing, etc. Monitoring oil substances in water helps control emissions and comply with environmental regulations.

[0003] In water treatment facilities, oil in water needs to be tested to optimize the treatment process and improve water quality. By real-time monitoring of oil in water, companies can more effectively manage resources, reduce waste, and improve production efficiency. Traditional detection methods, such as spectrophotometry and gas chromatography, usually require a long time and complex sample processing, and require manual operation, wasting manpower and detection efficiency.

[0004] According to the different particle sizes of oil droplets, oil substances in water can be classified into the following types: Microemulsion: The particle size is usually less than 1μm, the mixing state of oil droplets and water is relatively stable, and the oil is dispersed in the water to form a transparent liquid; Emulsion: The particle size is generally between 1μm and 100μm, and the oil droplets are dispersed in the water in the form of small particles to form an opaque liquid. Emulsions may be relatively unstable due to their large particle size and are easy to stratify; Crude oil: The particle size is usually between 100μm and several millimeters, and the oil droplets are clearly visible, usually appearing as oil floating on the water surface. Due to the large particle size, the stability of crude oil is low and it is easy to float or settle; Oil droplets: The particle size is less than 100 microns, which is common when the water body is polluted by oil, forming small oil droplets that may float on the water surface or suspend in the water. Oil droplets of different particle sizes have different behaviors and absorbance values ​​in water bodies. Therefore, when detecting oil substances in water, it is necessary to classify and detect the particle size of the oil droplets to optimize the treatment process and improve water quality.
