Abstract

The invention provides a washing liquid for treating light oil product polluted mud and sand and recovering oil, and a use method thereof, wherein the washing liquid comprises 68-92 parts by weight oftap water, 1-10 parts by weight of a water-soluble inorganic salt, 1-7 parts by weight of a gemini surfactant, 5-10 parts by weight of a cosurfactant and 1-5 parts by weight of hydrocarbons or lightoil. According to the invention, the washing liquid can be used at normal temperature; oil can be removed through simple mixing or stirring and mixing, and after cleaning is completed, the separated liquid phase is subjected to standing or centrifugation so as to be divided into an oil layer and a mixture layer containing effective components of the washing liquid, so that the oil is recycled while efficient oil removal is achieved, repeated cyclic utilization of the washing liquid can be achieved, the cost is low, and good economic value and application prospects are achieved.

Description

technical field [0001] The invention relates to a lotion for treating mud sand polluted by light oil products and recovering oil and its usage, belonging to the technical field of environmental pollution control. Background technique [0002] With the rapid development of the economy, especially the wide application of petroleum products, people's living standards have been greatly improved, life has become more and more convenient, and the demand for oil products has continued to expand. However, due to the leakage of oil products in the process of oil processing, oil exploration, oil transportation, etc., and the untimely discovery and improper treatment after the leakage, more and more mud and sand are polluted by oil products. Among them, light oil products are highly volatile, It will enter the human body through the food chain and accumulate, causing great harm to human health. Emergency treatment is required after the leak, and finding a fast and efficient treatment p...
