But at the same time, due to the poor hydrophilicity of the fiber itself, it sticks quickly after being stained with oil, making it difficult to wash off and regenerate.
In addition, due to structural d

Embodiment Construction

[0017] First of all, the hydrophilic modification is carried out on the long fiber filter material to improve the regeneration ability of backwashing.

[0018] The degreaser includes degreasing reactor cylinder 1, water inlet and overflow device 2, modified fiber bundle assembly 3, water outlet and backwashing device 4, degreasing cylinder connector 5, sampling port 6; The hydrophilic modified fibers are woven into component units in the form of fiber bundles, installed in the oil removal reactor (as shown in the attached picture), the upper part is fed with water, and the lower part is aerated to realize the agglomeration and coarse graining of oil droplets in oily wastewater. Reach the purpose of oil-water separation; Based on the characteristics of relatively cheap price, the present invention uses polyester fiber as filter material, and preferably modifiers such as polyvinyl alcohol, sulfamic acid, and polyethylene glycol carry out hydrophilic modification to this fiber, ch...

Abstract

Disclosed is a thick granulating grease intercepter with filament agglomeration, which leads oil dripping to be capable of floating upward in time along a filtering layer by lifting of bubbles through a reasonable filtering layer framework, thereby achieving double goal of thick granulating and filtering degreasing. The grease intercepter comprises a degreasing reactor barrel (1), an inflowing and overflowing unit (2), a modified fiber bundle assembly (3), a water-yielding and backwash unit (4), a degreasing barrel connector (5) and a sample port (6), wherein the degreasing reactor barrel (1) is divided into an upper portion and a lower portion which are integrated via the degreasing barrel connector (5), the modified fiber bundle assembly (3) is arranged in the degreasing reactor barrel (1), the sample port (6) is arranged on the side surface of the degreasing reactor barrel (1), and the upper portion and the lower portion of the degreasing reactor barrel (1) are respectively provided with the inflowing and overflowing unit (2) and the water-yielding and backwash unit (4). The upper portion of the degreaser feeds water, the lower portion of that aerates, thereby achieving the agglomeration and thick granulating of the oil dripping in oily wastewater and reaching water-oil separating.

Description

technical field [0001] The long-fiber agglomeration and coarse-grain degreaser of the present invention is an oil-water separation device for oily waste water, and belongs to the technical field of water treatment. Background technique [0002] Most of the existing oily wastewater treatment in my country is based on the old three sets of processes of "oil separation-air flotation-secondary biochemical", and supplemented by other treatment methods as needed. This process technology is mature, adaptable, and widely used, but it occupies a large area. The energy consumption and material consumption of the air flotation section of the core process are high, and the investment and operation costs are high, which is difficult for small and medium-sized enterprises to accept. Therefore, finding a technology that is efficient, stable, low in investment and operation costs, and reusable for oil removal has become an urgent problem to be solved. [0003] Studies in recent years have ...
