Description

Manufacturing methods of protection a block of an ecosystem and the block that use of corrosiveness aggregate of favoring environment}

The present invention relates to a method for producing environmentally corrosive aggregates using construction waste soil generated during the production of recycled aggregates produced during the recycling of food wastes and construction wastes. And eco-friendly corrosive aggregates solidified into granules by using construction waste soil produced in the production process of recycled aggregates produced during the recycling process of cement and construction wastes. It is related to a method of manufacturing " ecological block "

In recent years, our country has rapidly increased the type and amount of garbage due to the increase of organic waste such as food, paper, wood, construction waste caused by the construction of new buildings and the expansion of roads.

Among these, food wastes containing a large amount of water are easily decayed in a natural state, so that odors and rotten water are generated.

As of 2003, the amount of food waste in our country is 11,400 tons per day. As a treatment method, it is mixed with household waste or landfilled or recycled as feed or compost for livestock, but the concentration of salt is about 0.5 ~ 6%. The food waste of Korea, which is very high, has a fundamental problem in its disposal.

Construction waste is produced and used as aggregate in the process of being landfilled or recycled. As of 2003, the daily generation amount is 145,000 tons.

In the past, various methods of recycling food waste have been proposed. For example, Korean Patent Publication No. 10-2001-38363 (published on Feb. 15, 2001) proposes a soil production method using food waste and waste lime. While removing a large amount of water contained in food wastes, the process of decaying, mixing 5-10g of embadomonas bacteria and E. coli marcianos bacteria in the debris of food debris and then aged 65-80 ℃ while aging for 14-28 days A method of stirring the soil by adding 49% of general soil, wood, and other leaves was suggested.

In addition, Korean Patent Publication No. 10-2000-24612 (published May 6, 2000) was used to dry fermentation of food wastes for use as feed or to dry the residues to be used as a mixture of the floor packaging material.

In addition, construction waste is produced as recycled aggregate in the recycling process, and only a part of it is used for compaction and packing of floors, and a considerable amount of landfill is still buried due to the lack of diversity of use. Productivity inventory through the situation is not achieved.

On the other hand, although rivers are natural resources that have a great impact on human life and culture and have ecologically important values, they cannot be considered for long-term and specific environmental problems due to rapid urbanization and industrialization. It has been going on.

Recently, however, various attempts have been made to maintain the natural nature of rivers. However, there is still insufficient application of methods that are easy to preserve or restore the unique ecosystem while maintaining structural stability in existing concrete river maintenance methods.

In particular, the development of materials suitable for environment-friendly river maintenance and the development of construction methods using them require a long-term experimental monitoring of the environment, including ecological and landscape characteristics, as well as the hydraulic characteristics of a specific area. Has been accompanied by many difficulties.

Accordingly, the present invention has been made to solve such a conventional drawback, and aims at the development of a simple and environmentally friendly product in the process of recycling a large amount of food waste and construction waste.

Accordingly, the present invention has been made to provide a corrosive aggregate produced by mixing the ground food waste, Portland cement, construction waste soil, and the natural corrosive ecological block produced by using the same.

According to a first aspect of the present invention, there is provided a step of crushing the food debris from which foreign substances have been removed into a mesh size of 1 to 2 mm using a mixed grinder; Stirring and uniformly mixing 60 to 90% by weight of the ground food waste, 5 to 20% by weight of Portland cement, and 5 to 20% by weight of construction waste soil; Solidifying the mixture into granules having a particle size of 1 to 5 mm; It provides an environmentally friendly corrosive aggregate manufacturing method comprising the step of curing the granular material through a drying process.

In such a manufacturing method, as a method for removing foreign matters such as iron and vinyl from the collected food wastes, a sifting method, iron strip separation using an electromagnet, attraction screening and high speed wind screening methods are used.

The food debris from which the foreign matter is removed is pulverized using a mixer grinder so that the size of the pulverized particles can pass through a mesh having a size of 1 to 2 mm.

The waste collected at the construction site is cleaned of impurities during the intermediate treatment recycling process, and then the coarse recycled aggregate (size of about 6 to 15 mm) and the construction waste soil (0.3 mm or less) are prepared.

Stir to pellet or granulate 60 to 90% by weight of ground food waste, 5 to 20% by weight of Portland cement and 5 to 20% by weight of construction waste soil (sludge, pH 9-11) through agitation (mixing). Follow the steps.

In the stirring step, dehydration effect, odor removal is performed, a large amount of water is required in the Portland cement during the stirring, and the sterilization effect by heat generated during the hydration reaction appears.

In addition, the pH of the cement (12.5), the construction waste soil sludge is pH (9-11), the food waste pH (3-7) of the deodorizing effect due to the neutralization reaction in the stirring process, the dehydration effect and It is to provide a deodorant effect.

When the granulation is completed by stirring food waste, Portland cement, and construction waste soil, it is dried naturally for 1 ~ 3 days in summer and 7 days in winter, and the humidity is 60 ~ 70% for hay treatment using steam. 12 to 24 hours while maintaining the temperature at 150 ~ 180 ℃ to perform a solidification completion step to have a granule size of 1 to 5mm to obtain a corrosive aggregate granules.

 Since the granular material prepared by the above method provides strength of about 20 to 30 kg / cm 2, it can be packaged and distributed as a material capable of producing an ecological block. That is, the present invention provides a corrosive aggregate that can be shaped into various forms of ecological blocks in a second aspect.

In a third aspect, the present invention is 10 to 30% by weight of the corrosive aggregate produced according to the above-described manufacturing method and 60 to 80 weight of relatively thick recycled aggregate having a size of 6 to 15 mm mesh of recycled aggregate produced in the middle of construction waste treatment. %, 10 to 20% by weight of Portland cement and an amount of water necessary for imparting moldability, and a step of molding the mixture into blocks.

The ecological block molded through this method is installed in the river, where the food residues are used as the food chain of plants as the process of corrosion and extinction (weathering) caused by aerobic microorganisms of natural bacteria or fungi occurs. will be.

In addition, the root of the plant is to be vegetated through the pore having a pore ratio of about 10 to 30%.

Since the portland cement acts as a factor for determining the strength, it is possible to control the strength by varying the blending ratio, and when manufactured in the same manner as described above, the strength is about 100 to 150 kg / cm 2.

In addition, in order to increase the strength it is possible to improve the strength by increasing the number of times the portland cement is coated on the surface of the finished ecological block.

In a fourth aspect, the present invention provides an ecological block having a porosity of about 10-30% by being prepared according to the above-described manufacturing method.

Such an ecological block may be installed in a retaining wall, a stone wall, a raft block, etc. installed to prevent and protect the loss of waterways such as coasts, rivers, rivers and lakes.

On the other hand, the present invention can be produced in a variety of products, such as for example nude nude to be exposed to the outside without coating Portland cement when manufactured according to the above-described manufacturing method.

The present invention recycles food waste and construction waste discharged in large quantities to prevent the loss of waterways such as coasts, rivers, rivers, lakes, etc. The ecological block of the present invention useful for ecological protection replaces moisture by using food waste as it is Environmental pollution can be prevented, and the dewatering effect of portland cement and construction waste soil, odor removal and neutralization can be neutralized.

In addition, after manufacturing and installing various types of ecological blocks, weathering such as long-term corrosion and extinction caused by aerobic microorganisms of natural bacteria and fungi can be used as a food chain of plants. Very preferred.
