Problems solved by technology

The performance of commonly used filter materials in the sewage treatment of the petroleum industry is single, and only physical and mechanical methods can be used to remove impurities with large particle sizes and a small amount of oil. The oil removal effect is not good, and the filtration efficiency is not high. With continuous use or water quality Changes, the oil content of the filtered water is high, and it cannot meet the requirements of sewage reinjection or further resource utilization

Abstract

The invention relates to a modified filter material for sewage treatment in petroleum industry. The technical solution is that the modified formula is made of the following components by weight: 0.5 parts of polyvinyl alcohol PVA, 6.2 parts of polyethylene glycol PEG, 0.12 parts of polydiallyl dimethyl ammonium chloride PDDA; Sodium styrene sulfonate PSS: 5.3 parts. The beneficial effects are: 1. The coating has the property of self-cleaning and anti-oil adhesion; 2. The modified filter material has surface activity, is hydrophilic and oleophobic, and the effect of degreasing sewage is significantly improved; 3. After the surface activity of the filter material is reduced It can be re-modified to prolong the service life; 4. The filter material has a wider application range and wider application field, and the modified filter materials of different materials can be mixed to improve the overall effect; 5. The backwashing water consumption is small, the pressure is low, and it can be broken 6. Greatly shorten the oilfield sewage treatment process, simplify the sewage treatment process, save costs and reduce energy consumption; 7. Pressure resistance, wear resistance, and low maintenance costs in the later period.

Description

technical field [0001] The invention relates to modification treatment and application of a filter material, in particular to a modified filter material for petroleum sewage treatment. Background technique [0002] Filter material is the general term for water treatment filter materials, and it is a filter medium commonly used in water treatment. When water flows through the filter layer composed of filter material, the suspended particles in the water are filtered into the gaps of the filter material through interception and adsorption. The water is purified. The types of filter materials usually include quartz sand, gravel, pebbles, manganese sand, magnetite filter material, fruit shell filter material, porcelain sand filter material, ceramsite sand, fiber ball, etc. The performance of commonly used filter materials in the sewage treatment of the petroleum industry is single, and only physical and mechanical methods can be used to remove impurities with large particle siz...
