Problems solved by technology

[0003] However, due to the chemical surfactants used in existing dispersant products, such as fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate, etc., they will destroy the cell structure or metabolic enzyme activity of marine organisms, which are harmful to the ocean. The growth of organisms has high toxicity and poor biodegradability, so it is easy to cause secondary pollution to the marine ecological environment during use

Abstract

The invention belongs to the field of sea surface oil slick treatment, and in particular relates to an environmentally friendly oil dispersant capable of eliminating sea surface oil slicks, and also relates to a preparation method of the above-mentioned environment-friendly oil dispersant capable of eliminating sea surface oil slicks. The environmental protection oil dispersant capable of eliminating oil slicks on the sea surface of the present invention is composed of the following components in parts by weight: 20-30 parts of saponin, 15-25 parts of rhamnolipid, and 15-25 parts of starch-based surfactant , 7-15 parts of calcium lignosulfonate, 5-10 parts of ethylene glycol butyl ether, 20-30 parts of ethanol, 120-150 parts of purified water, and 3-6 parts of ethylene glycol. Compared with the prior art, the present invention has the advantages of low toxicity, high efficiency, elimination of oil slicks on the sea surface, and high biodegradation rate.

Description

technical field [0001] The invention belongs to the field of oil slick treatment on the sea surface, and in particular relates to an environment-friendly dispersant capable of eliminating oil slick on the sea surface, and also relates to a preparation method of the above-mentioned environment-friendly dispersant capable of eliminating oil slick on the sea surface. Background technique [0002] With the rapid development of my country's economy and the acceleration of the global industrialization process, maritime transportation is becoming increasingly busy, offshore oil exploration and development is rapid, oil spill accidents occur frequently, and the hazards of oil spill pollution are intensified. On the one hand, oil spilled pollutants float and adhere to marine animals, plants, and even human body surfaces, causing toxic damage to organisms; on the other hand, oil spilled pollutants are ingested by marine organisms during the process of diffusion and dissolution , passi...
