How to recycle coconut waste

DETAILED DESCRIPTION OF THE INVENTION [

[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

The present invention relates to a coconut waste, and more particularly, to a method for adsorbing a microorganism useful for coconut fruit, which is a waste, for recycling for purifying water and improving soil.

Coconut is a fruit belonging to the palm, and it is widely inhabited in the tropics. The coconut tree grows up to 45㎝ in diameter and 30㎝ in height, and 10 to 12 clusters are produced in one tree. Fully mature coconut is egg-shaped about 30 cm long and has a thick, fibrous cortex and a hard inner shell. The core of the inner shell is a white oil-like flesh, and when they are dried, a copper is formed. Copra is used as an oil to produce soaps and candles. The fibrous coir of the envelope is produced to make the rope.

In the Philippine and Sri Lanka islands in the southern part of the Pacific Ocean where the above-mentioned coconut is produced, and in the Indian Ocean, a large amount of coconut waste is generated after removing the core of the coconut and coir fiber among the coconut.

These coconut wastes are mainly composed of lignin and cellulose, which are composed of organic material in an amount of 95-99% and have very high water retention due to the porous structure. In addition, the above-mentioned coconut waste has an extremely high absorption capacity and, in the case of a water content of 15-30%, has a characteristic that water absorbs water having a weight of 5-9 times its weight and also contains a large amount of lignin, It is close to Mars material. Accordingly, some of the coconut wastes are used for moisture control of the organic fertilizer or as a base material for the horticultural soil.

[Technical Problem]

It is an object of the present invention to provide a method for effectively recycling coconut waste generated in the above-described manner.

[Structure and operation of the invention]

In order to accomplish the above object, the present invention provides a method for producing a microorganism-adsorbed coconut carrier comprising the steps of adsorbing useful microorganisms in fibrous coconut waste, and drying the coconut waste adsorbed on the useful bacteria ≪ / RTI >

The present invention also provides a method of using the coconut carrier on which the microorganism is adsorbed according to the present invention as a soil improving agent or as a water purification agent.

The present invention also provides a method of purifying a coconut waste by recycling coconut waste, comprising the steps of adsorbing a useful microorganism to a fibrous coconut waste and adding the coconut waste adsorbed by the useful bacteria to a contaminated water source.

In the present invention, before the step of adsorbing the useful microorganisms described above, the coconut waste is pretreated with water to wash the jet containing tannin, or the lye containing tannin is washed, It is preferable to carry out a process of directly adsorbing a microorganism having a decomposing function to lye or adding a nutrient component.

The step of adsorbing the microorganisms of the present invention may be carried out by immersing the coconut waste in a microorganism culture solution or culturing the microorganism by adding nutritional components together with microorganisms.

It is preferable that the microorganism of the present invention is a photoautotrophic bacterium such as red non-sulfur bacteria or red-sulfur bacteria.

In the present invention, it is proposed to use photo-nutritional bacteria belonging to the red non-sulfur bacteria and the red-sulfur bacteria as effective bacteria for preparing the soil improving agent or the water quality purifying agent.

In the present invention, various bacterium other than phototrophic bacteria are selected and the culture is directly adsorbed on crushed coconut wastes. Alternatively, cultured bacterium is cultured on a carrier to which nutrients have been added, followed by drying, as a soil improving agent and a water purification agent .

Fresh coconut waste contains a large amount of tannins. If soaked in water, the reddish brown lye will dissolve, which may hinder crop growth. Therefore, when fresh coconut waste is used as a soil conditioner, it is preferable to wash it with water in advance to the point where the reddish brown lye is completely removed. However, coconut waste, which is exported from Sri Lanka, is called "Coir fiber dust" and is stored in a state where it is washed out with rainwater for a long time while it is outdoors and the colored lye is completely eluted and removed. If tannin is used as a carbon source, it can be directly adsorbed on the coconut waste, or if it is cultured inoculated, the lye that inhibits the growth of the crop can be decomposed and removed. Therefore, the above-mentioned coconut waste can be used as a carrier of bacteria without being immersed in water.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described. However, the following embodiments are merely preferred embodiments of the present invention in order to facilitate understanding of the present invention, and the present invention is not limited to the following embodiments.

[Example 1]

The coconut fruit with the nucleus removed was crushed to a diameter of 0.1-0.5 cm, immersed in water, and washed until the reddish brown lye disappears. The washed coconut fruit was dried to a moisture content of about 20% by weight, and then 100 g of the washed coconut fruit was immersed in 500 ml of a culture solution (10% / ml) of a photo-nutrient bacterium Rhodbacter capsulata to sufficiently absorb the microorganism. And then dried until it was 60% by weight. Five grams of the thus-prepared sample was placed in 1 liter of plastic, and 500 ml of medium for non-sulfur sulfur bacteria was injected, followed by incubation while being illuminated with an incandescent lamp of 200 watt (about 300 lux). Four days later, red color appeared in the culture medium and proliferation of photo - nutritional bacteria was confirmed.

[Example 2]

The culture medium for culture of photoautotrophic bacteria except for the organic acid was added to the lye eluted from the coconut waste, and the inoculum was inoculated with the above-mentioned species. As a result, the culture liquid turned red and the inoculated species was found to proliferate using organic components contained in lye .

[Example 3]

50 g of the coconut carrier containing the photoautotrophic bacterium prepared in Example 1 was added to a 2 L flask containing 1 liter of urine, and then the mixture was illuminated with a 200 watt incandescent lamp and cultured under aeration. From 2 days later, odor generation decreased and after 5 days no odor was detected. This indicates that the malodorous substance was decomposed and removed by the action of the photo-nutrient bacteria adsorbed on the coconut carrier.

[Example 4]

The coconut carrier was immersed in the deionized water treated to 500 ppm of BOD by using photoautotrophic bacterium Rhodbacter capsulata at a ratio of 5: 1, adsorbed, and dried until the water content became 60% by weight while ventilating at room temperature.

As shown in Example 1, these samples were inoculated into a culture medium of photo-nutritive bacteria and cultured for one week while being illuminated, resulting in a red color of the culture medium. When the supernatant was inoculated on the agar medium, a large amount of Rhodobacter capsulata was detected.

[Example 5]

0.1% by weight of a suspension of Rhobacter capsulata (bacterial number 10 '/ ml) was added to the deionized water treated with photoinotrophic bacteria and adsorbed on a coconut carrier to obtain substantially the same result as in Example 4. As a result, And it was found that phototrophic bacteria multiply more rapidly.

[Effects of the Invention]

As described above, since the coconut waste sees a very high adsorption ability against microorganisms, it can be used as a high-rate microorganism material by adsorbing various useful microorganisms as an organic carrier. When the above-mentioned microorganism material is administered to the soil, it is possible to exert a synergistic effect by the action of a bacterium which is adsorbed on its carrier by further asking for a unique soil improving ability of the coconut fiber itself.
