PROBLEM TO BE SOLVED: To provide an apparatus for feeding a solid organic matter decomposition type liquid fertilizer that efficiently feeds a nutrient and avoids environmental deterioration by solid organic matter.SOLUTION: The apparatus for feeding the solid organic matter decomposition type liquid fertilizer includes a first elution water tank 3 for eluting iron fulvate in water, a second elution water tank 4 that decomposes solid organic matter in polluted water by a massive cleaning material 20 put inside the tank and prepares a nutrient liquid fertilizer and an elution component-containing water feeding apparatus that selects elution component-containing water in one or both of the elution water tanks of the first elution water tank and the second elution water tank and supplies the water to the sea and supplies the elution component-containing water to the sea. The second elution water tank is arranged so that an aerobic region in which oxygen-containing bubbles rise in water and an anaerobic region apart from the aerobic region alternately appear in the middle of a flow, a cleaning zone is filled with a massive cleaning material, polluted water is alternately passed through the aerobic region and the anaerobic region while being brought into contact with the massive cleaning material in the middle of passing the cleaning zone to decompose solid organic matter in sludge water.【課題】栄養塩を効率良く供給することができ、しかも固形有機物による環境悪化を回避することができる固形有機物分解型液肥供給装置を提供する。【解決手段】フルボ酸鉄を水に溶出可能な第1溶出用水槽3と、内部に入れた塊状浄化材20により汚濁水の固形有機物を分解して栄養塩液肥を調整する第2溶出用水槽4と、第1溶出用水槽と第2溶出用水槽とのいずれか一方または両方の溶出用水槽内の溶出成分含有水を選択して海に供給可能な溶出成分含有水供給装置とを設置し、溶出成分含有水を海中に供給する固形有機物分解型液肥供給装置であって、第2溶出用水槽は、酸素含有気泡が水中を上昇する好気性領域と該好気性領域から外れた嫌気性領域とが流れの途中に交互に出現するように配置し、浄化域には塊状浄化材を充填し、浄化域を通過する途中で汚濁水を塊状浄化材に接触させながら好気性領域と嫌気性領域とを交互に通過させて汚泥水中の固形有機物を分解する。【選択図】図1
