Description

Manufacturing method of organic fertilizer based on seaweed waste {MANUFACTURING METHOD OF THE MANURE MADE FROM BROWN SEAWEED WASTES}

The present invention relates to a method for manufacturing seaweed waste as organic fertilizer, and in particular, the collection of seaweed waste consisting of stems, spores, roots, etc. of seaweed in the collection process and wash them with high water by washing process to include them in seaweed waste. Remove the base and crush the above seaweed waste finely by crushing process, and then mix the quicklime with the seaweed waste in the quicklime mixing process and inject the seaweed waste and the quicklime mixture into the container in the natural digestion process. The theme is seaweed waste, which can prevent pollution of the marine environment and contribute to agricultural production by reducing harmful bacteria contained in seaweed waste by natural heat generation, stabilizing seaweed waste, and obtaining organic fertilizers that are good for spraying on soil. Regarding manufacturing method of organic fertilizer .

In general, the cultured seaweed harvests only the leaves and dumps the roots, spores and stems into the sea.

The seaweed waste reaches 15-180,000 tons, which is 5-60% of the total seaweed production of 300,000 tons, and the seaweed waste is concentrated in the period of February to April.

However, the seaweed wastes dumped into the sea as described above is deposited on the bottom of the sea to block the oxygen inflow of water, causing the problem of killing marine plants and organisms.

In addition, the suspended matters decomposed in the seaweed waste had a significant problem of reducing the transmitted light of the sea water and at the same time sinking in the seaweed leaf in culture, causing not only the physiology of the seaweed but also causing pests to ravage the fishery.

Despite the above serious situation, the reason for dumping seaweed waste into the sea as it is is because there is no way to treat the large amount of seaweed waste, but rather it creates another environmental pollution on land. The city just dumped into the sea.

In addition, since the seaweed waste is composed of more than 25% of the polysaccharide alginic acid and mucosa and more than 80% of the water contained in seaweed ears, it is quickly decayed in the form of porridge (gel) on land, so the waste is collected It becomes impossible.

Therefore, the method of utilizing the seaweed waste should be developed first to prevent the marine pollution by seaweed waste.

The purpose of the present invention for solving and solving these conventional problems,

It provides the purpose of contributing to agricultural production by blocking marine pollution and ultimately by making seaweed waste into organic fertilizer.

In order to achieve the above object, the present invention,

In the collection process, the seaweed waste consisting of stems, spores and roots of seaweed is collected and washed with high water by the washing process to remove the bases contained in the seaweed waste and finely shredded the seaweed waste by crushing process. In the next quick-lime mixing process, the quick-waste is mixed with the seaweed waste, and in the natural digestion process, the sea-weed waste and the quick-lime mixture are put into the container, and the natural heat of the quick-lime reduces the harmful bacteria contained in the sea-waste waste and stabilizes the seaweed waste. It is possible to achieve the purpose of the present invention by obtaining a water-soluble organic fertilizer to the soil.

The method for producing seaweed waste of the present invention as a calcined fertilizer will be described in detail by process by the accompanying drawings as follows.

A collection process for collecting seaweed waste consisting of stems, spores and roots of seaweed,

Washing process of washing or depositing seaweed wastes by high water to remove the base contained in the seaweed waste collected in the collection process,

Shredding process for finely crushing the seaweed waste washed in the washing process in the crusher,

A mixing process of mixing about 5-25% by weight of quicklime with finely crushed seaweed waste in the crushing process;

The seaweed waste and quicklime mixture, which have undergone the mixing process, are put into a container and sealed to kill harmful bacteria contained in the seaweed waste by natural heat of about 50-95 ° C. generated from quicklime and stabilize the seaweed waste at the same time. It is composed of digestive spontaneous pyrogenic process to obtain organic fertilizers in water with good moisture content of 25-40%.

When explaining an embodiment for carrying out the present invention as described above is as follows.

First, in the collection process, only the seaweed leaves hanging from the seaweed rope are collected from the seaweed farm, and the seaweed waste consisting of stems, spores and roots of seaweed remaining on the rope is separated through a separate mold.

That is, the seaweed wastes can be separated from the rope by inserting one end of the rope into the separating mold and extracting only the rope.

And, the seaweed waste separated from the rope is transported in a fishing net or a collection ship.

As described above, the seaweed waste collected by the collection process contains many bases, thereby removing the bases by washing.

In other words, during the transfer of the seaweed waste to the conveyor to remove the base by spraying fresh water with a spray or to remove the base by depositing the seaweed waste in a tank containing fresh water.

In addition, the seaweed waste washed in the washing process is transferred to the crusher of the crushing process to be finely crushed to a size of about 5-10mm horizontally.

And, finely crushed seaweed waste in the shredding process is mixed by adding about 5-25% by weight of quicklime to the seaweed waste in the mixing process.

In addition, the seaweed waste and quicklime mixture after the mixing process is put into the container in the natural heat of digestion process by killing harmful bacteria contained in seaweed waste by the natural exotherm of about 50-95 ℃ that is generated from the quicklime to stabilize the seaweed waste At the same time, it is possible to obtain organic fertilizers with good water solubility in soil with acidity pH 12-14 and moisture content 25-40%.

In the digestive natural heating process, quicklime is used together with shellfish to neutralize soil acidified by chemical fertilizer abuse in agricultural production. Lime refers to hydrated lime and hydrated lime is made through digestion. .

In addition, the above digestion is dry digestion and wet digestion, but in the natural exothermic process of the present invention, the quicklime is digested by moisture contained in seaweed waste having water content of 80-90% instead of water used for wet digestion. The heat generated during the digestion process is used to kill harmful bacteria and stabilize seaweed waste.

Therefore, the mixed and digested seaweed waste organic fertilizer as described above is made in a very good state to use because it does not need to be dried, so it does not scatter in the wind and there is no lump.

Thus, the present invention collects seaweed waste consisting of stems, spores and roots of seaweed in the collection process and washes them with high water by washing process to remove the bases contained in the seaweed waste and crushed seaweed Finely crush the waste and then mix the quicklime with the seaweed waste in the quicklime mixing process, and in the natural digestion process, put the seaweed waste and the quicklime mixture into the container and reduce the harmful bacteria contained in the seaweed waste by the natural heat of quicklime It is possible to stabilize the wastes and to obtain organic fertilizers that are good to be sprayed on the soil. The seaweed wastes contain a large amount of trace elements and the organic matters of the seaweed wastes themselves are good, but are deficient in crops. Absolute ingredient that cures disorders of microelement deficiency (Magnesium, phosphorus, potassium and manganese) are contained in seaweed waste as shown in Table 1 below.

Mineral content in seaweed waste (mg in 100 g) calcium magnesium sign potassium iron Yod copper manganese zinc nickel chrome Seren Ca Mg P K Fe I Cu Mn Zn Ni Cr Se 1,300 1,170 420 5,500 7 36 34 9.5 3.1 2.4 7 3

Therefore, by using the seaweed waste as a fertilizer by the present invention, it is possible to fundamentally block the environmental pollution source, to preserve fish farms to provide a stable farming environment to fishermen, and high quality organic fertilizers can greatly contribute to agricultural production. .

In particular, food waste, sewage waste, and sea sediment, which have been used as organic fertilizers until now, contain salts, so they have limited disadvantages in open-air crops due to the salt damage. Since the salt can be used continuously and stably in large amounts with the salt completely removed, the utilization as a resource increases.

In addition, the organic fertilizer using the seaweed waste has a useful effect that the industrialization is guaranteed and high profitability and added value can be obtained because the amount of the organic fertilizer is very large.
