Problems solved by technology

[0003] At present, the commonly used treatment methods for emulsified wastewater with better treatment effects include chemical dosing and process treatment. The chemical used in the dosing treatment is not effective in treating the emulsion at high temperature, and the process treatment basically uses two methods: grille and air flotation. This method is not effective for high-temperature emulsified sewage treatment, and when the oil content is high, the air flotation aerator head will be blocked and the normal production process will be affected.

Abstract

The invention discloses an emulsified waste water treatment oil removing agent and a preparation method and use method thereof. The emulsified waste water treatment oil removing agent is prepared from, by weight, 0.02% to 0.05% of glycerol, 0.06% to 0.08% of poly(diallyldimethylammonium chloride), 0.80% to 1.00% of sodium silicate, 1.00% to 2.00% of magnesium sulfate, 1.00% to 2.00% of aluminum potassium sulfate and 95.89% to 96.10% of water. The content of oil, suspended solids, COD and other pollutants in emulsified waste water treated through the emulsified waste water treatment oil removing agent is greatly reduced, and when the emulsified waste water treatment oil removing agent is used, the feeding quantity is small, and treatment cost is low. Waste oil can be recycled after being treated, the waste water reaches the standard, and benefits can also be created. When the emulsified waste water treatment oil removing agent is applied, equipment modification is very small, investment is small, and the treatment effect is remarkable. The treatment operation is easy, high reliability is achieved, and management is facilitated. The emulsified waste water treatment oil removing agent is free of toxins, harm and secondary pollution, and up-to-standard emissions of the waste water can be ensured. The treatment effect is good in stability, and popularization is facilitated. The application range is wide, the recovery rate of oil products can be increased, the oil content in drained water can be reduced, and stable running of subsequent treatment units is promoted.

Description

technical field [0001] The invention relates to an industrial emulsified wastewater treatment agent, in particular to an emulsified wastewater treatment deoiling agent and a preparation method and application method thereof. Background technique [0002] Some production units of refining and chemical enterprises will produce a large amount of high-temperature oil-containing emulsified sewage during the production process. The instability of the sewage will lead to serious emulsification of sewage and increase the difficulty of treatment. If the sewage is directly discharged, it will cause great pollution to the environment, and if it enters the sewage treatment plant, it will also have a relatively large impact on the sewage treatment plant. Therefore, it needs to be pretreated and then sent to the sewage treatment plant for advanced treatment, and discharged after reaching the standard. [0003] At present, the commonly used treatment methods for emulsified wastewater with...
