Oil-water separator and method for separating oil and water by oil-water separator

Abstract

The invention discloses an oil-water separator and a method for separating oil and water by the oil-water separator, wherein the oil-water separator comprises a water inlet zone, a clapboard zone, a separating zone and a flotation zone which are connected in order; the clapboard zone comprises a plurality of diagonal upward clapboards; the water inlet zone is provided with a fluid inlet, and sewage in the water inlet zone is risen to the separating zone through the clapboard zone; the upper part of the separating zone is adjacently provided with a first oil absorbing roller and a first oil collecting tank; a first scraper blade is arranged on the first oil collecting tank, and the lower part of the flotation zone is provided with an aeration structure; the upper part of the flotation zone is adjacently provided with a second oil absorbing roller and a second oil collecting tank; a second scraper blade is arranged on the second oil collecting tank, the flotation zone is provided with a first fluid outlet. Through separating oil and water to be physical settlement, oil absorption by the oil absorbing roller, aeration oil absorption and multi-grade treatment processes, the oil-water separator structure is reasonably arranged, thus the separating efficiency and effect are improved.

Description

Technical field [0001] The present invention relates to the technical field of oily sewage treatment, in particular to an oil-water separator and a method for oil-water separation using the oil-water separator. Background technique [0002] With the rapid development of my country's industrialization, resource and environmental issues have become increasingly severe. In the production process of petroleum, chemical, steel, metallurgy, and other industries, a large amount of oily sewage will be produced. If oily sewage is not recycled, it will cause waste; discharge into rivers, lakes or bays will pollute water bodies and affect the survival of aquatic organisms. ; Used for agricultural irrigation, it will block the soil gaps and hinder the growth of crops. Existing oil-water separation equipment is often complicated in structure, and it is difficult to meet the requirements of water quality treatment. Therefore, how to rationally set the structure of the oil-water separator to i...

Problems solved by technology

In the production process of petroleum, chemical, steel, metallurgy, and other industries, a large amount of oily sewage will be produced. If the oily sewage is not recycled, it will cause waste; if it is discharged into rivers, lakes or bays, it will pollute the water body and affect the survival of aquatic organisms. ; Used for agricultural irrigation, it will block the soil voids and hinder the growth of crops

The existing oil-water separation equipment is often complex in structure, and it is difficult to meet the requirements of water quality treatment. Therefore, how to reasonably set up the structure of the oil-water separator to improve the separation efficiency and separation effect is a very important issue.
