Oil pollution is one of the important types of water pollution, especially in some estuaries and offshore waters,There are a lot of oil discharged into the ocean every year.And this chapter of the water quality online monitoring instrument manufacturers to understand the related problems of oil pollutants on water bodies.
Oil pollutants are mainly from industrial emissions, as well as cleaning the cabins and machinery of oil carriers and some accidents, offshore oil production and other ways. Among them, oil tanker accidents belong to explosive concentrated pollution sources, which belong to devastating hazards!
So What kind of Harm Will Oil Pollution Bring?
Petroleum is a mixture of alkanes, alkenes and aromatic hydrocarbons, which is harmful in many ways after entering the water. For example, the formation of oil film on the water can hinder the role of water rehabilitation; Oil sticking to fish gills can cause them to suffocate; Adhesion to algae and floating matter will cause their death; In addition, oil can also inhibit the laying and hatching of water birds, resulting in a large number of bird deaths; There is also a significant reduction in the quality of aquatic products.
How Do You Know the Amount of Oil in Water?
Water quality can be tested by relevant instruments to detect the specific content of oil in water. An OIL-8000-in-water OIL analyzer produced by Hangzhou Modi is designed to measure the concentration of oil (hydrocarbons) in water. The instrument uses ultraviolet fluorescence method to measure the concentration of oil molecules in water. Oil molecules are activated into an excited state under specific ultraviolet light. This excited state is very unstable and will return to the ground state soon. In the process of returning to the ground state, radiation fluorescence will be produced, and the concentration of oil molecules in the water sample is proportional to the intensity of radiation fluorescence emitted. The water sample is sent to the colorimetric tank after the pretreatment device. The light source is parallel to the oil molecules in the colorimetric tank water sample, and the resulting fluorescence is irradiated on the fluorescence sensor. Before the ultraviolet light is emitted and the fluorescence sensor is received, an accurate filter system is installed to control the emission wavelength of ultraviolet light and select the specific fluorescence wavelength scattered back by the received oil molecules. The received fluorescence intensity corresponds to the concentration of oil in the water sample to a certain extent, and the linear relationship can be made clearer by the selection and control of the transmission and reception wavelength of the filter light system.
