Problems solved by technology

These experiments have not started from the perspective of establishing immobilized microbial ecology, and what is fixed is often a single fungus or algae, and the materials are expensive, which is difficult to achieve in large water bodies
It is worth mentioning that biofilm treatment of sewage, although a certain micro-ecological system has been established on the membrane, is still not comprehensive. The treatment method adopts the ex-situ treatment method, which is used to treat large-scale polluted water bodies, and the project volume is very large. ,High expense

Embodiment 1

[0023] Embodiment 1: prepare polyester composite material

[0024] Take an appropriate amount of polyester staple fiber, with a length of 1 cm, a diameter of 3 μm, and colors such as white, black, and gray. The above-mentioned fibers are formed into a net with a carding machine, and then fixed on both sides of the polyethylene foam EPE (Expand aple polyephylene, pearl cotton) with a needle punching machine. The grammage of the composite material is 50g / m 2, wherein the polyethylene foam gram is 20g / m 2 . The composite material is divided into two sides, one side is darker, gray-black; the other side is lighter, gray-white. Different colors can naturally select microorganisms with different characteristics.

[0025] The prepared composite material was placed in 5% NaOH solution, kept at 90°C for 10 minutes, washed until neutral, and then dried. Under this condition, the surface structure of the fiber changes, such as figure 2 as shown, figure 1 It is a control photo of u...

Embodiment 2

[0026] Embodiment 2: prepare polyester composite material

[0027] Take an appropriate amount of polyester staple fiber, the length is 10cm, the diameter is 50μm, and the color is white, black and gray. The above-mentioned fibers are formed into a net with a carding machine, and then fixed on both sides of the polyethylene foam EPE (Expand aple polyephylene, pearl cotton) with a needle punching machine. The grammage of the composite material is 500g / m 2 , wherein the polyethylene foam gram is 300g / m 2 .

[0028] Put the prepared composite material in 30% NaOH solution, keep it warm at 50°C for 120min, wash until neutral, and dry. Under this condition, the surface structure of the fiber changes, such as image 3 as shown, figure 1 It is a control photo of unmodified fiber. .

Embodiment 3

[0029] Embodiment 3: Preparation of polypropylene fiber composite material

[0030] Take an appropriate amount of polypropylene staple fiber, the length is 3.5cm, the diameter is 20μm, and the color is white, black and gray. The above fiber is formed into a net with a carding machine, and then fixed on both sides of the polyethylene foam EPE (Expand aple polyephylene, pearl cotton) with a needle punching machine. The grammage of the composite material is 230g / m 2 , wherein the polyethylene foam gram is 90g / m 2 .

[0031] The above composite material is suspended in the plasma processing chamber, the frequency of the excitation electrode of the plasma gas is 13.56MHz, the vacuum pumping valve is opened, and the working gas is introduced. The working gas is oxygen, the working pressure is 15Pa, and the power of the radio frequency power supply is 50W.

Abstract

The invention discloses a making method and application of composite artificial fiber material, which comprises the following steps: netting the polypropylene or polyester staple fiber with length at 1-10cm and diameter at 3-50um through cotton carding machine; fixing the net on the polyethylene foam through needing machine; disposing the needling material through 5-30% NaOH for 10-120 min under 50-90 deg. c; washing to neutral; dehydrating; drying; obtaining the product; or using plasma technique to dispose the composite material; modifying the surface to obtain the product; fitting for harnessing pollution of eutrophication water body to form good micro-ecological system; balancing the producer, consumer and decomposer in the water body; reinforcing the natural purifying ability of system; reducing the harnessing cost; accelerating the restoration of ecological system of entire water body to main the sustainability.

Description

technical field [0001] The invention relates to a preparation method and application of a composite artificial fiber material. Background technique [0002] The key to the control of water eutrophication is to remove nitrogen, phosphorus and organic matter from the water ecosystem, that is, to control eutrophication from two basic ways: the external environment and the internal environment: one is to adopt external environmental control measures to cut off or reduce the eutrophication of the water body. External pollution loads mainly include sewage interception + construction of sewage treatment plants, water replenishment technology and other methods; the second is to adopt internal environmental control measures, mainly including sediment dredging, artificial circulating water treatment, and the use of aquatic organisms, microorganisms or artificial aquatic organisms to affect the water body ecology. system control methods. The above methods are sometimes used simultaneo...
