Method for fuel-water separation:

Chemical method

The chemical method, also known as the chemical method, is a method of adding chemicals to convert the pollutants in the wastewater into harmless substances by chemical action, so that the wastewater can be purified. Commonly used chemical methods are neutralization, precipitation, coagulation, redox and so on. Coagulation is mainly used for oily wastewater. The coagulation method is to add a certain proportion of flocculant to the oily wastewater. After hydrolysis in the water, a positively charged micelle and a negatively charged emulsified oil are formed to generate electrical neutralization, the oil particles aggregate, the particle size becomes larger, and flocculation is formed at the same time. The oil-like substance adsorbs fine oil droplets, and then separates oil and water by means of sedimentation or air flotation.

Biological oxidation

Biological oxidation is a method of purifying wastewater by using the biochemical action of microorganisms. Oil is a hydrocarbon organic matter that can be broken down into carbon dioxide and water by life activities such as metabolism by microorganisms. The organic matter in the oily wastewater is mostly in the dissolved and emulsified state, and the BOD5 is high, which is beneficial to the biological oxidation.

Flotation

Flotation method, also known as air flotation method, is a water treatment technology that is being researched and promoted continuously at home and abroad. The method is to introduce air or other gases into the water to generate fine air bubbles, so that some small suspended oil droplets and solid particles in the water adhere to the air bubbles, and float to the water surface together with the air bubbles to form scum (oil-containing foam layer), and then use an appropriate The oil skimmer skims the oil.
