Problems solved by technology

The key to realizing the coalescence degreasing technology is that the coalescence material component is lipophilic and has a large specific surface area. The current coalescence degreasing is mainly based on wetting and coalescence, which cannot effectively break the oil-in-water in the emulsified oil. And the water-in-oil structure, resulting in the emulsified oil removal effect is not obvious; a small number of amphiphilic materials have unsatisfactory results due to their own material problems and process design problems in water treatment applications

Abstract

The invention relates to a biparental high polymer coalescence degreasing material as well as preparation and an application thereof. The mass ratio of polyethylene to polyvinyl chloride to polypropylene to silica is (20-60): (30-50): (20-60): (20-40), and the materials are mixed evenly for 20-60 minutes at 45-70 DEG C; injecting the mixture into a wave-shaped die under the drying condition at 150-210 DEG C, solidifying and cooling; dipping the upper surface of the material into a solution with strong oxidizing property at 20-50 DEG C for 2-10 minutes, wherein intense rubbing and collision happen to the sewage on the upper surface with hydrophily, of the material, so as to smash the structure of water in oil and oil in water of the emulsified oil to release fine oil drop, and then a wetting action happens on the lower surface with lipophilicity, of the material, the fine oil drops form big oil drops continuously, and then the big oil drops float on the liquid level under the action ofself or outer buoyancy, thereby realizing the cracking and separating of the emulsified oil.

Description

technical field [0001] The invention relates to a high molecular polymer coalescence degreasing material with strong lipophilicity and strong hydrophilicity and its preparation and application. Background technique [0002] In oil extraction, petroleum refining, leather, paper, textile, food, catering and other industries, there will be a large amount of oily sewage that needs to be treated and discharged, and oil removal is one of the most critical treatment links. In particular, the emulsified oil contained in sewage is very harmful. How to remove emulsified oil efficiently and environmentally friendly is an important topic in the research of oily sewage treatment. [0003] The oil droplet size of the emulsified oil is less than 10 μm, generally 0.1-2 μm. The oil droplets often form a stable emulsion due to the surfactant in the water, which has two structures: water-in-oil (O / W) and oil-in-water (W / O). The stability of emulsified oil depends on the nature of wastewater ...
