KR970021039A - Manufacturing method of fertilizer using waste rock wool - Google Patents

Abstract

The present invention relates to a method of manufacturing fertilizer using waste rock wool after cultivation of rock wool for cultivation and construction rock wool, and stops the supply of nutrient solution after the end of crop cultivation, and repeats the salt accumulated in the rock wool to supply water and to wash, After measuring the electrical conductivity to confirm the washing of salts and dried until the water is removed, the dried rock wool is granulated to 2-lOmm size using a grinder, sterilized by heat sterilization at 100 ℃ or more by direct or indirect drying method Alternatively, the construction waste rock wool is cut into 2-lOmm by a crusher, but in order to remove the water repellency of the rock wool and impart hydrophilicity, a surfactant is sprayed onto the fiber and the coated rock wool is dried by direct or indirect drying method. Waste rock consisting of livestock containing in this way the rock wool and adding fermentation agent and leaving it until the fermentation is completed. It relates to a method for producing fertilizer using cotton.

The rock wool treated by the present invention exhibits an excellent effect as a soil improver when used alone without mixing with livestock, as well as mixed with clay, diatomaceous earth, vermiculite, and can be usefully used as a soil for cultivation in all directions. .

Claims (3)

In the method of manufacturing fertilizer by treating waste rock wool after use of cultivated rock wool for nutrient solution, the supply of nutrient solution is stopped after crop cultivation, and the salts accumulated in rock wool are repeatedly supplied with water and washed, and electrical conductivity is measured. After confirming the washing of the salt and dried until the water is removed, granulated dried rock wool to a size of 2-10 mm using a grinder, sterilized by heating and sterilizing the granulated rock wool at 100 ℃ or more by direct or indirect drying method The method of manufacturing fertilizer using waste rock wool, characterized in that the mixed rock wool such as gyebun, pig flour, milk powder and so on treated as such and left until the fermentation is completed by adding a fermentation agent. In the method for manufacturing fertilizer by treating waste rock after use of building rock wool, the waste rock wool is cut into 2-10 mm by a crusher, and at this time, the surfactant is sprayed evenly to remove water repellency and impart hydrophilicity. It is composed of coating on the fiber, drying the coated rock wool by direct or indirect drying method, and mixing livestocks such as poultry meal, pig meal, and cow flour on the treated rock wool, and adding fermentation agent to leave it until the fermentation is completed. Fertilizer manufacturing method using waste rock wool. According to claim 1 or 2, instead of mixing livestock such as poultry, pig meal, milk powder, etc. to the treated rock wool, clay, diatomaceous earth, vermiculite, etc. are mixed to prepare a mixed culture soil useful as a soil for cultivation of grass. Fertilizer manufacturing method using waste rock wool. ※ Note: The disclosure is based on the initial application.
