Problems solved by technology
However, because the non-dispersive infrared spectrophotometry does not take aromatic compounds into account, when the aromatic content in the oil exceeds 25%, its absorption coefficient is very different from that of ordinary oil (in which the aromatic content does not exceed 15%)
[0015] However, no matter which method is used, it only measures the oil content in the water. When solid particles, oil, and air bubbles are contained at the same time, it is difficult to achieve the purpose of simultaneous online measurement.

Abstract
The invention provides a water micro-oiliness and pollution degree on-line analysis method based on a CCD (charge coupled device) scattered refraction spectrum method. The water micro-oiliness and pollution degree on-line analysis method is characterized by comprising the steps that a parallel light beam is subjected to a transparent container containing liquid to be analyzed and is received by a CCD linear array detector; and the oil content and the solid particle content of the liquid are calculated by combining the scattering and refracting properties of water oil drops and solid particles according to the scattering and refracting conditions reflected by spectral distribution received by the CCD linear array detector. By utilizing the water micro-oiliness and pollution degree on-line analysis method and device, the contents of water oil and solid pollutants can be simultaneously detected on line, and the operation is simple and convenient, and fast.
Description
technical field [0001] The invention relates to an on-line analysis method and device for micro-oil content and pollution degree in water based on CCD scattering refraction spectroscopy. The invention is used for sewage detection and can simultaneously detect oil and solid particles contained in discharged sewage on-line. It can be used in water quality testing, chemical sewage, drilling platforms, cooling water, tanker terminals, etc. Background technique [0002] With the development of industry, sewage treatment and discharge has become a serious problem currently facing, and the indicators and detection of sewage discharge have also become an important topic at present. [0003] The most important component of environmental pollution in sewage is oil, which seriously damages the ecological environment, affects the safety of drinking water, and affects the living environment of rivers and oceans. [0004] At present, the common detection methods of oil concentration in w...
