Problems solved by technology

[0002] Aiming at the defects of the conventional separation methods of oily industrial wastewater at home and abroad, such as incomplete oil treatment due to unsatisfactory demulsification, high consumption of oil regeneration and recycling process and low oil-water reuse index, etc., the vacuum demulsification and corrugated membrane are proposed. A method and process for purifying oily industrial sewage by integrating macromolecule coarse-graining and hollow fiber ultrafiltration membrane. The corrugated film plate used in this process is usually made of pure polypropylene extrusion molding. The disadvantage is that when it is used for oil-water separation treatment of oily sewage, the plate is easy to be stained with oil, the oil-water separation effect is not good, and it is not conducive to the regeneration of the plate

Embodiment 1

[0017] Example 1, a corrugated film plate for oil-water separation, by weight, 72 parts of polypropylene, 14 parts of impregnated activated carbon, 10 parts of molybdenum disulfide, and 4 parts of chlorinated paraffin were evenly mixed, and then the mixture was melted at 170 ° C After filling the mold, wherein, the impregnated activated carbon is the filtration after immersing the activated carbon in 0.1 part of dilauryl thiopropionate, 0.85 part of ammonium oleate, 0.05 part of dioctyl sebacate, and 99 parts of ethanol solution for 3 hours. Dry the charcoal.

Embodiment 2

[0018] Example 2, a corrugated film plate for oil-water separation, by weight, 70 parts of polypropylene, 20 parts of impregnated activated carbon, 5 parts of molybdenum disulfide, and 5 parts of chlorinated paraffin were evenly mixed, and then the mixture was melted at 165 ° C After filling the mold, wherein, impregnated activated carbon is the filtration after impregnating activated carbon in 0.3 parts of dilauryl thiopropionate, 1.5 parts of ammonium oleate, 0.06 parts of dioctyl sebacate, and 98.14 parts of ethanol solution for 4 hours. Dry the charcoal.

Embodiment 3

[0019] Example 3, a corrugated film plate for oil-water separation, by weight, mix 80 parts of block copolymer polypropylene, 10 parts of impregnated activated carbon, 7 parts of molybdenum disulfide, and 3 parts of chlorinated paraffin, and then put the mixture at 168 ° C After hot-melting, mold filling, wherein, impregnating activated carbon is to impregnate activated carbon in 0.2 parts of dilauryl thiopropionate, 1.72 parts of ammonium oleate, 0.08 parts of dioctyl sebacate, and 98 parts of ethanol solution for 5 hours filter-dried activated carbon.

Abstract

A thin curve-corrugated plate for the separation of soil and water relates to water treatment materials and is molded by a compound of polypropylene, impregnated activated carbon, molybdenum disulphide and chloroparaffin which are melt under 165-170 DEG C, wherein, the impregnated activated carbon is activated carbon dip treated by alcohol solution containing dilauryl thiodipropionate, oleamide and di-n-octyl sebacate. The obtained thin curve-corrugated plate is characterized in that the thin curve-corrugated plate is oleophilic but sticks no oil, and can be regenerated in real time. By utilizing the thin curve-corrugated plate in industrial oil-bearing industrial waste water, oil is easy to be demulsified and polymerized, thus improving the elimination efficiency of oil droplet and leading the quality of separated purified water to achieve reclaimed water reusing standard.

Description

technical field [0001] The invention relates to a water treatment material, in particular to a corrugated film plate, a water treatment material capable of rapidly separating oil and water in oily sewage, and provides a preparation method for the corrugated film plate. Background technique [0002] Aiming at the defects of the conventional separation methods of oily industrial wastewater at home and abroad, such as incomplete oil treatment due to unsatisfactory demulsification, high consumption of oil regeneration and recycling process and low oil-water reuse index, etc., the vacuum demulsification and corrugated membrane are proposed. A method and process for purifying oily industrial sewage by integrating macromolecule coarse-graining and hollow fiber ultrafiltration membrane. The corrugated film plate used in this process is usually made of pure polypropylene extrusion molding. The disadvantage is that when it is used for the oil-water separation treatment of oily sewage,...
