Description

Method for Manufacturing Bed Soil Using Paper Mill Sludges and Rejected Wastes from Paper Making Process and Bed Soil Obtained by the Method}

The present invention relates to a horticulture artificial clay manufacturing method using the sludge generated in the paper mill and waste generated from the selection and sorting process of the papermaking process (hereinafter referred to as "paper waste") and horticultural artificial clay obtained therefrom More specifically, the present invention relates to a horticulture artificial clay manufacturing method adapted to cultivate crops by fermenting wastes generated from a paper mill using soil microorganisms and horticultural artificial clay obtained therefrom.

Many of the environmental problems caused by the acceleration of industrialization are related to the treatment of industrial waste, and the amount of domestic waste has recently increased by about 7% every year. Paper mill sludge, which is generated in large quantities in domestic paper mills, is one of these organic industrial wastes and generates the largest amount in a single industry. The amount of sludge produced at the paper mill is estimated to be about 1.6 million tons in 2002, but the treatment technology is insufficient. Waste generated from paper mill sludge and paper processing is continuously increasing due to the continuous expansion of paper companies and the increase of paper market. On the other hand, the wastes generated at the paper mills are 61% treated using their own incinerators, 27.8% commissioned by specialized treatment companies, 7.5% recycled, and 3.7% treated by landfill. Compared to waste, the recycling rate of wastes including wastes is significantly lower.

The incineration method can reduce the volume and quantity by incineration of the plant waste in the combustion boiler, but the byproduct of incineration ash remaining after incineration is treated as another by-product to be landfilled. The ever-increasing landfill system has caused serious environmental problems such as difficulty in securing the site, generation of leachate, odor, and ground subsidence of landfills, leading to an urgent need for new treatment technologies. Therefore, in Korea, the waste problem has been introduced to reduce waste, recycle, incinerate, and landfill in order to minimize the amount of landfill that is finally disposed of. In line with this management system, most of the waste generated by paper companies focuses on the reduction and solidification through dehydration process, and some of them rely on marine dumping methods.

However, this method of treatment cannot be a fundamental solution for the actual treatment of paper mill waste, and in particular, the London Convention has banned the dumping of industrial wastes since 2013, and it is time to urgently prepare a new method of treatment. have.

In Korea, the use of paper mill waste has been used as steelmaking agents, earthworm breeding, building materials, sidewalk blocks, landfill cover, and barrier wall materials in steel mills, but few commercialized technologies have been reported. As mentioned above, the most preferred method is to use waste to recover energy by incineration in the incinerator owned by the paper mill, and the ash produced is used as raw material for cement. In addition, in advanced countries such as the US, cellulose fibers contained in paper mill wastes are extracted and applied to soil or ethanol is produced by fermentation and enzymatic reaction. Is so complex that it presents a problem in economics.

Therefore, the inventors of the present invention examined the development of artificial soils for cultivation of horticultural crops using paper mill wastes generated in large quantities as part of the development of suitable technology for resource recycling and use of paper mill soils. When fermentation of process waste using microorganisms found that artificial clay for seedlings can be developed and completed the present invention.

In addition, in the fermentation step, it is preferable to ferment the paper waste by adding a fermentation promoter selected from the group consisting of animal amino acids, vegetable amino acids, herbal nutrients, lactic acid bacteria and rock minerals. In addition to the fermentation promoter, it may be fermented by further adding ocher, ink, urea fertilizer or wood vinegar.

In the manufacturing method of artificial horticultural clay according to the present invention, it is preferable that the water content after drying of the fermented papermaking waste is 10-15%.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a process chart showing a process for manufacturing horticultural artificial clay using papermaking waste according to the present invention.

Referring to Figure 1, the manufacturing method of horticultural artificial clay using paper waste according to the present invention comprises the step of fermenting by adding soil microorganisms to the paper waste (S11); Drying the fermented waste (S12); Molding the dried fermentation waste and sorting to have a predetermined size (S13); And a step (S14) for mixing the cocopite and other subsidiary materials in the selected fermentation waste.

In the step (S11) of adding the soil microorganisms to the paper waste, the paper waste is in the sludge of the dewatered cake state in the wastewater treatment plant of the paper mill and other sorting and selection process of the papermaking process Generated waste (reject) and the like may be used, preferably may be waste of paper mills producing good quality paper and feed art paper, the water content of the paper waste used in fermentation is 40 ~ 60% suitable for microbial activity It is preferable that it is the range of. In addition, the microorganisms for fermenting paper waste is a microorganism that rapidly decomposes lignocellulosic biomass, and is preferably collected at a place where deciduous ripening of the forest has progressed considerably. After collecting the microorganisms, it is preferable to prepare a microbial stock solution through a culture process, and add the microbial stock solution to 0.02 to 0.1% of the total weight of the papermaking waste and use it for fermentation.

Paper waste to which the soil microorganisms are added may be fermented into an automatic fermentation tank, and fermentation may be carried out by anaerobic fermentation for 10 to 20 days with periodic stirring in a low temperature of 25-30 ° C. and a medium temperature area of 50-65 ° C. It is preferable to aerobic fermentation together. The reason for changing the fermentation temperature to low and medium temperature is because the type of microorganism used in the fermentation is composed of microorganisms that are active in various temperature ranges.

Before the fermentation step through the periodic stirring at low and medium temperature, the fermentation may be performed in a fast time (about 15 days) while periodically stirring for 10 minutes per hour at 40 to 60% water content using an automatic fermenter.

On the other hand, in order to ferment papermaking waste, fermentation accelerators may be added in addition to soil microorganisms. In this case, fermentation accelerators include fermentation broths (animal amino acids) made by fermenting animals and fish for at least one year, fermentation broths (vegetable amino acids) made by fermenting plants such as buttercups for at least 6 months, garlic, ginger, donkey, cinnamon, licorice, etc. A fermentation broth made by fermenting the same herbal medicine for 6 months or longer, and finely crushed gravel around mountains or rivers for the purpose of preventing crop disturbances and seedling pests, and then selected from the group consisting of minerals collected by passing water through them and lactic acid bacteria. The fermentation promoter is preferably used in the range of 0.01 to 0.05%, respectively, based on the total weight of the paper waste.

In addition, in addition to the fermentation promoter, ocher, ink, urea fertilizer or wood vinegar may be added. The loess, ink or urea fertilizer can improve physical properties such as density of artificial clay, water retention. It is preferable to add in the range of 10 to 30% and the urea fertilizer in the range of 0.01 to 0.02% based on the total weight of the yellow soil and the papermaking waste.

In addition, wood vinegar may be added to supplement the alkalinization of artificial clay made from paper waste, wood vinegar may not only control the acidity (pH) of artificial clay, but also suppress the generation of odor generated during waste fermentation. After diluting the wood vinegar by 1,000 times, it is preferable to use within 1.0 to 2.0% of the total weight of papermaking waste.

In the step (S12) of drying the fermented papermaking waste may be dried in the air while being careful not to mix the foreign matter. Drying can be dried to about 10 to 15% water content is easy to form topsoil.

Forming the dried fermentation waste, and sorting to have a predetermined size (S13) in the molding using a general molding apparatus in this field, the paper waste topped through the molding process for sorting to a suitable size for horticultural soil, It can be screened into those having a predetermined size by using a standard mesh of a screen form having holes of a certain size, and is preferably screened to have a size of 4 mm or less in diameter.

In step S14 of mixing the selected fermentation wastes with cocoot, cocoite is mixed in order to improve the physical properties or plant growth suitability of the fermentation waste. The coco peat may improve physical properties such as moisture retention as well as density, and may be mixed to compensate for relatively insufficient components such as K, N, and Mg.

The coco pit may be mixed in a volume ratio of 3: 7 to 5: 5 with respect to the fermentation waste. Pearlite or the like may be mixed in addition to the cocoite.

Horticultural crop cultivation experiments were conducted to verify the efficacy of the horticultural artificial clay prepared by the above process, which will be described in detail below.

Example 1

75 kg of the dehydrated cake paper with 45% moisture content is added to the automatic fermenter, stirred and crushed.The microbial stock used for fermentation is added 0.05% to the total weight of the paper waste to adjust the water content to 50%. Then, the mixture was stirred periodically with temperature changes at 20 ° C., 35 ° C. and 60 ° C., and then fermented for 35 days. Subsequently, the sample was taken out from the auto fermenter and dried in the air to have a water content of 12%. Then, the dried waste was ground and powdered to an average diameter of 4 mm or less to prepare a circular artificial clay.

Example 2

In addition to the microbial fermentation broth, 1,000 times diluted wood vinegar is added about 1.2% to the total weight of waste, and animal and vegetable amino acids are added in the same manner as in Example 1 except that 0.04% is added to the total weight of waste. Was prepared.

Example 3

Horticultural artificial clay was prepared by mixing cocopites in the circular artificial clay obtained in Example 2 in volume ratios up to 0%, 30%, and 50% with respect to the circular artificial clay.

Test Example 1

Comparison of Physical Properties of Circular Artificial Clay

In order to grasp the physical characteristics of the circular artificial clay obtained from Example 2, the density, true density, porosity and water retention capacity are measured and shown in Table 1 below. The characteristics are also shown.

Density
(g / cm3) True density
(g / cm3) Porosity
(%) Water retention capacity
(%) Paper waste 0.62 3.08 79.97 44.58 Example 2 0.75 1.62 53.61 62.35 Commercial soil 0.11 0.41 74.36 51.63

When the paper waste was produced from the circular artificial clay through the table, the density of the physical property was slightly increased, but it was about 7 times higher than the density of the commercial clay used in the market. Density is deeply related to the growth of the roots of crops among the physical properties of the soil. The growth of these roots not only has a physical effect of supporting the top part of the crop, but also absorbs the nutrients necessary for the entire growth of the crop. Therefore, it can be seen that the physical improvement of the circular artificial clay prepared for the root growth is necessary. have.

Comparison of Physical Properties of Horticultural Artificial Clay

Physical properties of the horticultural artificial clay of Example 3 and the circular artificial clay of Example 2 in which cocoite was mixed with the circular artificial clay in order to improve the manufactured circular artificial clay to have physical properties suitable for fabric growth The results are shown in Table 2 below.

Density
(g / cm3) True density
(g / cm3) Porosity
(%) Water retention capacity
(%) Example 2 0.75 1.62 53.61 62.35 Example 3 0.53 1.39 58.62 111.44

In Table 2, the artificial horticultural clay mixed with coco peat was confirmed that the physical properties were improved as the soil density such as low density and moisture retention ability.

Changes in Nutritional Components of Horticultural Artificial Clay

On the other hand, in order to determine the growth suitability of the artificial clay for horticulture prepared according to Example 3 of the present invention, the essential nutrient content was measured and the results are shown in Table 3, and for comparison, circular artificial clay and commercial clay were compared. Shown together.

Major nutrients (%) Micronutrients (mg /%) P K Ca Mg Fe Cu Zn Mn Mo B Example 2 0.22 0.09 1.01 2.23 8960 10.8 58.18 60.02 62.82 10.38 Example 3 0.23 0.48 0.89 2.52 8463 120.8 11.69 63.95 20.22 13.45 Commercial soil 0.11 0.60 0.52 1.10 4495 198.4 224.8 259.2 12.88 332.2

Through Table 3, it can be seen that the addition of cocopite is effective in replenishing nutritional deficiencies as well as changes in physical properties. In other words, the K component, which was lacking in circular artificial soil, could be raised to a level comparable to that of commercial soil by mixing cocopite.

Test Example 2

Crop cultivation experiment 1

Each of the circular artificial clays obtained in Example 2 was placed in a tray for growing hair, sowing cucumber and cabbage seeds to show growth according to the cultivation time, and the results are shown in FIG. 2. Through Figure 2, it was confirmed that the growth of plants in artificial soil made of waste paper mill was fermented.

Crop cultivation experiment 2

Seedlings of cucumber seedlings by seeding cucumber seeds in circular artificial clay obtained in Example 2 and horticultural artificial clay obtained in Example 3, commercially available fertilizer-containing ubiquitous and fertilizer-free clay, Leaf length and leaf width were measured and the results are shown in Table 4.

As can be seen from Table 4, it was confirmed that the growth of the plant also in the artificial artificial circular soil of Example 2, the horticultural artificial clay of Example 3 mixed with coco peat and almost the seedlings grown in ubiquitous soil Similar growth is shown.

Example 4

75 kg of dehydrated cakes with 45% water content are added to the auto fermenter and stirred to crush them.Then, the loess is added to 10% of the waste weight and the microbial stock used for fermentation is 0.05% of the total weight of the waste. After addition, the water content was adjusted to 58%, and then stirred periodically with temperature changes at 25 ° C., 35 ° C. and 60 ° C. to proceed with fermentation for 35 days. Subsequently, the sample was taken out from the auto fermenter and dried in the air to have a water content of 10%. Then, the dried waste was powdered to an average diameter of 4 mm or less using a laboratory blender to form a circular artificial clay. Prepared.

Example 5

The artificial artificial clay for horticulture was prepared by mixing circular artificial clay and cocoite in a volume ratio of 7: 3.

Example 6

The artificial artificial clay for horticulture was prepared by mixing the circular artificial clay and cocoite in a volume ratio of 5: 5.

Example 7

A circular artificial clay was prepared in the same manner as in Example 4 except for adding 20% by weight of loess.

Example 8

A circular artificial clay and coco peat obtained in Example 7 were mixed with a volume ratio of 7: 3 to prepare a horticultural artificial clay.

Example 9

The artificial artificial clay for horticulture was prepared by mixing circular artificial clay and cocoite in a volume ratio of 5: 5.

Test Example 3

Comparison of Physical Properties of Horticultural Artificial Clay

The physical properties of artificial clays prepared from Examples 4 to 9 were compared and the results are shown in Table 5 below.

Density
(g / cm3) True density
(g / cm3) Porosity
(%) Paper waste 0.62 3.08 79.97 Example 4
(0% of coco feet) 0.79 1.3 39.23 Example 5

(50% of coco feet) 0.57 0.9 36.66 Commercial soil 0.105 0.41 74.36

As can be seen from Table 5, as the addition ratio of cocopit is increased, the density and the true density are lowered proportionally, but when the cocoite is added at 50% or less, the density and the true density are higher than those of conventional paper waste. It is high.

Analysis of Nutritional Components and Heavy Metals in Artificial Horticulture

Essential plant nutrients of horticultural artificial clay obtained from Examples 4 and 7 were analyzed, and the results are shown in Table 6 below, and the heavy metal content was analyzed and the results are shown in Table 6 below.

Major nutrients (%) Micronutrients (mg /%) P Al K Ca Mg Fe Cu Zn Mn Mo B Paper waste 0.22 0.19 0.10 1.01 2.63 9429 6.9 0.9 62.0 61.30 9.9 Example 4 0.02 0.01 0.02 2.43 0.70 107 0 0 0.2 0.04 0 Example 7 0.46 19.18 0.13 20.66 0.88 131 0 0 0.5 0.02 0 Commercial soil 0.12 0.21 0.67 0.52 1.10 4495 198.5 224.8 259.8 12.88 332.23

Through Table 6, although the phosphorus and calcium components, which are the main nutrients essential for plant growth, showed higher or better values than commercial soils, potassium and magnesium components tended to be somewhat lower than general commercial soils. Boron component was not detected at. Therefore, it was confirmed that supplementation of potassium component is necessary by adding cocoite to artificial clay.

As can be seen from Table 7, the growth rate of corn between commercial and artificial soils was not large until about 15 days in corn, but after 15 days, cocotite and fermentation in 20% of ocher The growth rate of the sprouted corn was the fastest in artificial clay mixed with 5: 5 by volume. In case of cucumber, germination progressed about 1 day in commercial soil, but there was no significant difference in growth rate between commercial soil and artificial soil. The growth rate was highest in the topsoil.

Example 10

75 kg of dehydrated cakes with 45% water content are added to an automatic fermenter and stirred to crush them.Then, 20% ocher, 10% salted and 1.5% urea fertilizer are added to fermentation. The microbial stock solution was added 0.05% of the total weight of the waste, the water content was adjusted to 60%, and then stirred periodically with temperature changes at 25 ° C., 35 ° C. and 60 ° C., followed by fermentation for 35 days. Subsequently, the sample was taken out from the auto fermenter and dried in the air to have a water content of 10%. Then, the dried waste was powdered to an average diameter of 4 mm or less using a laboratory blender to form a circular artificial clay. Prepared.

Example 11

A circular artificial clay was prepared in the same manner as in Example 10, except that 1.5% of wood vinegar diluted 1000-fold with respect to the total weight of waste was added to the automatic fermentation tank.

Comparison of Physical Properties of Horticultural Artificial Clay

The physical properties of the artificial clay prepared from Example 10 are compared with paper waste and commercial clay, and the results are shown in Table 9 below.

Density

As can be seen from Table 9, the addition of ocher and ink was higher than the density of commercially available soil, but it was confirmed that the improvement was greatly. In addition, in the case of the porosity, the porosity is falling due to the effect of filling the pores of artificial clay as the fine particles of ocher are added, but the water retention ability is equivalent to that of commercial soil. It is believed that the addition of ink affected not only the removal of odor during fermentation but also the improvement of physical properties such as water retention.

Analysis of Nutritional Components and Heavy Metals in Artificial Horticulture

Analysis of essential plant nutrients of the artificial horticultural clay obtained from Example 10 is shown in Table 10, and the results of analyzing the heavy metal content is shown in Table 11 below.

Major nutrients (%) Micronutrients (mg /%) P Al K Ca Mg Fe Cu Zn Mn Mo B Paper waste 0.22 0.19 0.10 1.01 2.63 9429 6.9 0.9 62.0 61.30 9.9 Example 10 0.46 19.20 0.75 23.55 1.90 3500 1.26 0 0.5 0.02 0 Example 11 0.49 18.31 0.75 24.55 3.54 3670 2.10 0 0.46 0.02 0 Commercial soil 0.12 0.21 0.67 0.52 1.10 4495 198.5 224.8 259.8 12.88 332.23

Through Table 10, all of the essential nutrients necessary for plant growth exceeded commercially available soils by adding ink, urea fertilizer or wood vinegar, but boron was not detected in terms of trace elements. However, trace elements do not have a significant effect on plant growth, and the addition of cocopites can fully compensate the trace elements.
