Description

Lock of vegetable fiber for purification of the polluted water and waste water}

The present invention relates to a plant fiber material lock for sewage and wastewater purification. More specifically, the surface area per unit volume to allow the microorganisms used for sewage and wastewater to fully grow is significantly larger than that of other contact materials, and the porosity is high. In addition, the removal load is greater than that of any standard media, and it has a large porosity, so that the resistance to air, waste, and waste water passage is very low, and the surface area acting upon the collision adsorption of particulates or gases is very large, and the current is collected by special surface treatment. The present invention relates to a plant fiber material rock for filthy and wastewater purification, and to a method for producing the same, which facilitate and optimize microbial habitat.

In general, the lock (lock) is a small elastic body made by curling (curling) the flora and fauna fibers and synthetic fibers, etc. in a spring shape and bonded to the surface, microorganisms responsible for oxidative decomposition and reduction of organic matter for the treatment of wastewater This is to allow for formatting.

Conventionally, as a lock as described above, only a synthetic fiber yarn was cut to a predetermined length, and then a nonwoven fabric or the like was used, which was dissolved or fixed by fixing an adhesive.

However, if the conventional lock having the above-described configuration is installed in water for a long time, loosening and sagging occur, not only the function is significantly degraded, but the habitat environment of microorganisms that decompose waste and waste water is poor, and the reproduction of microorganisms is reduced. There is a problem that effective wastewater treatment cannot be expected, and synthetic fiber yarns are used, which requires the cost of purchasing raw materials, and when discarded, landfilling or incineration should be carried out. When the components are discharged and landfill is hardly decomposed, there was a problem causing environmental pollution.

In addition, in the case of a rock manufactured using animal and plant fibers, the animal and plant fibers, which are the material of the rock, are decomposed or deteriorated by the wastewater and wastewater introduced therein. As a result, it was cumbersome and costly to maintain.

Accordingly, an object of the present invention is to solve the problems of the prior art described above, and by using natural plant fibers, it has excellent affinity with microorganisms and is well suited for the incubation of microorganisms that oxidatively decompose and reduce organic matters. It does not cause environmental pollution, does not cause loosening or sagging in the water, has a large porosity, activates the propagation and activity of microorganisms, enables more efficient wastewater treatment, and there is little risk of decomposition or deterioration. It is to provide a vegetable fiber lock for the purification of wastewater, which can be used at low cost.

It is another object of the present invention to provide a method for easily manufacturing the above-mentioned wastewater purification plant fiber material lock.

In order to achieve the above objects as well as other objects that are easily expressed, the present invention uses a shell of coconut having a thin fiber shape, such as synthetic fiber, with little pretreatment as a material of the rock, but drying the coconut shell to a certain length. After cutting into pieces, coconut shells are laminated in an amount of 0.5 to 2 kg per unit area, compressed, and then activated carbon adsorbing foreign substances, bio-ceramic for activating the activity of microorganisms by radiating far infrared rays, and the activated carbon and bio-ceramic coconut Mixing the adhesive in a suitable proportion to the shell by spraying on both sides of the laminated coconut shell to be evenly distributed and dried to produce a rock, and has excellent affinity with microorganisms due to the use of natural plant fibers, oxidative decomposition and It is well suited for the habitat of reducing microorganisms, It does not cause environmental pollution at the time of disposal, does not cause loosening or sagging in the water, has a large porosity, activates the growth and activity of microorganisms, enables more efficient wastewater treatment, and almost no risk of decomposition or deterioration. It can be used for a long time, so it is possible to obtain a vegetable fiber lock for purification of wastewater and wastewater, which is inexpensive to maintain.

The present invention is described in more detail as follows.

The waste water purification lock of the present invention is laminated with a coconut shell per 1 m 2 in an amount of 0.5 to 2 kg and pressed, and then, 40 to 65% by weight of the adhesive, 20 to 45% by weight of activated carbon, and 15 to 40% by weight of the bio-ceramic. The resulting mixture is characterized as sprayed and dried on both sides of the pressed coconut shell to be 40-50% by weight relative to the coconut shell weight.

In addition, the manufacturing method of the rock for purification of wastewater of the present invention includes a processing step of selecting a coconut shell and cutting it to a size of 5 to 10 cm after drying; Stacking coconut shells in an amount of 0.5 to 2 kg per m 2; Compressing the laminate at a pressure of 1,000 to 5,000 kg per m 2 after lamination is completed; Separately preparing a mixture comprising 40 to 65% by weight of adhesive, 20 to 45% by weight of activated carbon, and 15 to 40% by weight of bio-ceramic and adding 10% by weight of diluent based on the total weight of the mixture; Spraying evenly on both sides of the compressed coconut shell laminate such that the mixture is 40-50% by weight relative to the weight of the coconut shell; It is characterized by consisting of a step of natural drying for a predetermined time.

Coconut husk used in the present invention is a coconut palm bark, and the coconut is a soft brown jelly in the soft brown fibrous husk is used in various dishes, but the coconut shell is superheated and recycled as activated carbon at all Since recycling is not performed and manufacturing of activated carbon requires a lot of manufacturing costs, almost all of the waste is discarded because it is rarely used but is used only in a special case.

However, in view of the fact that the coconut shell has an excellent effect as activated carbon in the present invention, it was found that the shell is suitable for use as a wastewater purification lock, although it is not as effective as the overheated activated carbon when used as a lock after drying. The present invention has been completed.

In particular, compared to the lock made of synthetic fiber yarn, water is much less turbid, like milky color, and the smell of water is significantly reduced, and organic matter floats on the water or bubbles occur in the tank. The incidence of P is significantly reduced, which is estimated to be the effect of filtration and deodorization on the coconut shell itself.

In addition, since coconut shell is a natural vegetable fiber, it has excellent affinity with microorganisms, and thus, the activity of microorganisms is excellent when compared to rock made of synthetic fibers.

First, the coconut shell is collected to remove the keratinous portion and various foreign matters that are not fibrous, completely dried and then cut into a size of 5 to 10 cm. However, the completely dried coconut husk is hard and not easy to cut, so the cutting and drying process may be altered.

When cutting the coconut shell to a size of less than 5cm it is not easy to manufacture a coconut shell into a laminate, if it exceeds 10cm there is a problem that the adsorption of fine particles or filtration efficiency of the suspended matter deteriorated Occurs.

The cut coconut shells are laminated in an amount of 0.5 to 2 kg per 1 m 2.

At this time, if the amount of coconut shell used is less than 0.5 kg per 1㎡, the thickness of the laminate produced is thin, so that the degree of filtration, adsorption, and microbial film formation is weak, and the overall efficiency of wastewater purification is lowered. There is a weak initial price synergistic effect, which is not economical.

The laminate is pressed at a pressure of 1,000 to 5,000 kg per m 2.

Separately, the adhesive was composed of 40 to 65% by weight, activated carbon 20 to 45% by weight, bio-ceramic 15 to 40% by weight, and after preparing a mixture in which 10% by weight of the diluent was added to the total mixture weight, both sides of the laminate were prepared. Spray to 40 to 50% by weight based on the weight of the coconut shell.

Although the adhesive agent is not specifically limited in this invention, The 701SP (product name) of Ogong Bond Co., Ltd. was used.

The amount of the adhesive is preferably 40 to 65% by weight based on the total weight of the mixture composed of activated carbon, bio-ceramic and adhesive, and when the amount of the adhesive is less than 40% by weight, the adhesion of the coconut shells is not easy. It is difficult to manufacture as, and if it exceeds 65% by weight, the porosity of the laminate is lowered, the filtration rate is not good, and there is a disadvantage that the amount of activated carbon, bio-ceramic is relatively reduced and the deodorizing effect is lowered.

Activated carbon and bio-ceramic are adsorbed and attached to the rock to activate the activity and reproduction of the inhabiting microorganisms as well as to obtain the effect of deodorization and serves to prevent the decay and degeneration of the coconut shell.

Activated carbon is a material that is made of carbon (carbide such as wood, coconut shell, lignite, bituminous coal) so that the micropores are well developed by high activation, and has a large internal surface area connected to the path of countless microspaces developed during the activation process. Used for various purposes such as decolorization, deodorization, removal of solvent recovery harmful gases, the present invention exhibits the effects of filtration, decolorization, deodorization of organic matter.

The amount of activated carbon is preferably used in an amount of 20 to 45% by weight based on the total weight of the mixture composed of the adhesive, the bio-ceramic and the activated carbon. When the amount of the activated carbon is less than 20% by weight, the effect of filtration, decolorization, and deodorization of organic matter is weak. One disadvantage is that if it exceeds 45%, the activated carbon is more likely to be detached from the surface of the lock, and thus the durability of the effect due to the use of activated carbon is lowered, and the activated carbon itself acts as a pollution source.

Bio ceramics are inorganic materials such as oxides, nitrides, carbides, etc., and generally have much higher corrosion resistance, heat resistance, and abrasion resistance than metal materials and organic materials. It has a variety of functions, such as function, optical function, biological function, in the present invention improves the corrosion resistance of the coconut shell, and serves to activate the activity and reproduction of microorganisms by far-infrared rays emitted from the bio-ceramic.

The amount of the bio-ceramic is preferably used in an amount of 15 to 40% by weight based on the total weight of the mixture composed of the adhesive, the activated carbon, and the bio-ceramic. When the amount of the bio-ceramic is less than 15% by weight, the corrosion resistance of the coconut shell is deteriorated. There is a disadvantage in that it does not show an effect on the activity and reproduction of microorganisms by far-infrared rays emitted from bio-ceramic. If it exceeds 40%, the synergistic effect of addition is weak, and it is not economical, and it may detach from coconut shell and form a precipitate. .

Mixing of the adhesive, bio-ceramic and activated carbon is a diluent commonly used in the technical field to which the present invention belongs, 10 to 30% of the total weight of the adhesive, bio-ceramic and activated carbon is added and mixed, and the mixing method is a technique to which the present invention belongs Although all methods commonly used in the art may be used, in the present invention, the solids, that is, the bio-ceramic and the activated carbon, are first mixed in a stirrer to homogeneously mix, and then a diluent and an adhesive are added and stirred to prepare a mixture.

By preparing a mixture as described above, sprayed on both sides of the coconut shell laminate, and then air-dried for two days to complete the manufacture of the vegetable fiber rock for purification of wastewater of the present invention.

As described above, in the present invention, pretreatment is hardly required as the material of the lock, and the coconut shell is dried after cutting to a certain length by drying the coconut shell using a thin shell of fiber having a thin fiber shape such as synthetic fibers. Laminated and compressed in an amount of 0.5 to 2 kg per unit area, and activated carbon that adsorbs foreign substances, bio-ceramic for activating microbial activity by radiating far infrared rays, and adhesive for attaching the activated carbon and bio-ceramic to coconut shell are suitable. It is very suitable for incubating microorganisms which oxidize and reduce organic matters because it has excellent affinity with microorganisms due to the use of natural plant fiber by spraying the mixture in proportion to the laminated coconut shells so that it is evenly distributed and dried to produce rock. Underwater, without causing environmental pollution during disposal It does not cause loosening or sagging, and has a high porosity, and enables more efficient waste and wastewater treatment by activating the propagation and activity of microorganisms, and it can be used for a long time because there is little risk of decomposition or deterioration. Vegetable fiber locks for wastewater purification were obtained.
