Problems solved by technology

[0004] 1. The production cost of traditional packing is high and the performance is low;
[0005] 2. Traditional packing has low specific surface area and poor adsorption capacity;
[0006] 3. The surface of traditional fillers has poor biocompatibility, is perishable, easy to store sludge, and the speed of biofilm formation is slow;
[0007] 4. Traditional fillers have low hydraulic scouring force and low load resistance, so the biofilm can only fall off by itself;
[0008] 5. Traditional packing is not easy to clean and regenerate, and has a short service life;
[0009] 6. Traditional fillers have poor degradability of pollutants, unstable biological phase, and single types of microorganisms

Embodiment 1

[0038] Such as figure 1 Shown, the preparation steps of a kind of disc-shaped biological carbon fiber water treatment filler of the present invention are as follows:

[0039] Step 1: Wind the carbon fiber into a bundle structure and put it into a Soxhlet extractor and degumming the surface with acetone for 10 hours;

[0040] Step 2: Rinse the degummed carbon fiber with deionized water to remove the acetone on the surface and the carbon fiber glue remaining on the surface of the carbon fiber to obtain bio-carbon fiber;

[0041] Step 3: cutting the bio-carbon fiber obtained in step 2 into several sections with a length of 40 cm to obtain a disc-shaped bio-carbon fiber water treatment filler 2;

[0042] Step 4: Place the prepared disc-shaped bio-carbon fiber water treatment filler 2 vertically in the water to form a biomimetic structure in the shape of aquatic plants, which floats with the flowing water.

[0043] Among them, the specific production method of the disc-shaped bio...

Embodiment 2

[0054]Another preparation method (not shown in the figure) of the bio-carbon fiber water treatment filler of the present invention, wherein, the disc-shaped bio-carbon fiber filler in Example 1 is replaced by a bundle-shaped bio-carbon fiber filler, and the bundle-shaped bio-carbon fiber water treatment filler The specific production method is as follows: the symmetrical center of the bio-carbon fiber cut into several sections is pasted horizontally on a non-woven fabric with a width of 64 cm and a width of 4 cm, and the non-woven fabric is used as a benchmark for fixing the carbon fiber to obtain a bundle-shaped bio-carbon fiber water treatment filler. , and a total of 55 parts of truncated bio-carbon fibers are pasted thereon. Other preparation methods are the same as Steps 1 to 4 of Example 1, and will not be described in detail here.

[0055] The above two biological carbon fiber water treatment fillers prepared by the present invention have better hydrophilicity, biocompa...

Abstract

The invention relates to a preparation method and application of a biological carbon fiber water treatment filler, and belongs to the field of water treatment in environmental engineering. High-strength biological carbon fiber is subjected to a surface degumming treatment by acetone by a Soxhlet's extractor to obtain high-strength carbon fiber with good biocompatibility; and the high-strength carbon fiber treated with degumming is prepared into a bundle or disc shape. The biological carbon fiber water treatment filler can be applied to purification treatment of freshwater aquaculture water, printing and dyeing wastewater, oily wastewater, pharmaceutical wastewater and effluent from sewage treatment plant, so as to produce good economic benefits, social benefits and environmental benefits.

Description

technical field [0001] The invention relates to a preparation method and application of biological carbon fiber water treatment filler, belonging to the field of environmental engineering water treatment. Background technique [0002] At present, most of the research on fillers at home and abroad is concentrated on the material, shape, and surface properties of the filler, mainly from the perspective of increasing biomass and enhancing the efficiency of biological reactions, and from the perspective of the spatial structure, installation method and packing density of the filler. That is to say, there are still few studies on enhancing mass transfer efficiency and improving fluid flow state, and there are not many related literatures and reports. Therefore, based on the mass transfer mechanism of multiphase fluid dynamics systems and from the perspective of enhancing mass transfer efficiency, the research and development of high mass transfer biological carrier packing is not...
