In order to solve the above problems, the present invention is composed of 5 to 10% by weight of quicklime of citrus sludge for the first reaction, and inorganic powder of 8 to 20% by weight of citrus sludge for the second reaction.
상기 생석회는 무기소재로 산성인 감귤스러지를 알카리성으로 만들어 준다. The quicklime is an inorganic material that makes the citrus acidic and alkaline.

이하, 본 발명의 바람직한 실시예로 형성된 감귤슬러지의 고형화 처리방법을 이용하여 감귤슬러지를 처리한 실험결과를 설명하면 다음과 같다. Hereinafter, the experimental results of treating citrus sludge using the solidification treatment method of citrus sludge formed by the preferred embodiment of the present invention will be described.
상기한 감귤슬러지에 생석회 및 무기물파우더를 투입하여 상기한 방법으로 실험하였을 경우의 고형물의 수분함유량은 8~16% 정도로 나타나고, 고형물의 PH는 11로 나타났다. When the quicklime and inorganic powder were added to the citrus sludge, the water content of the solids was about 8 to 16% and the pH of the solids was 11.
상기한 결과로 감귤슬러지는 수분함량이 매우 낮은 건조한 상태로 처리되었음을 알 수 있고, 고형물이 강한 알카리성을 띄고 있으므로, 산성화된 토양을 중화시키는 토질개량재로 활용될 수 있다.As a result, it can be seen that citrus sludge has been treated in a dry state with a very low moisture content, and since the solid has strong alkalinity, it can be used as a soil improver to neutralize acidified soil.
