PROBLEM TO BE SOLVED: To provide an active ingredient for biological activation capable of effectively solving a problem of an inferior activity of microorganisms for subjecting a hardly decomposable organic matter to biodegradation treatment in microorganism treatment of organic matter-containing water having a high CODvalue of 500 mg/L or more which is not measured by a CODvalue containing also a more hardly decomposable or more slowly decomposable organic matter, and a biological treatment method for hardly decomposable organic matter-containing water by using the same.SOLUTION: There is provided: a biological activating agent for improving a biological treatment performance which is used for biological treatment of an aqueous system having a CODvalue of 500 mg/L or more containing a biologically hardly decomposable or slowly decomposable organic matter, in which an iron salt is contained as a principal ingredient; and a biological treatment method for hardly decomposable organic matter-containing water using the biological activating agent.SELECTED DRAWING: None 【課題】ＣＯＤMn値の測定値では測定されない、より難分解性或いはより遅分解性である有機物をも含む、ＣＯＤcr値が５００ｍｇ／Ｌ以上と高い有機物含有水の微生物処理において、この難分解性有機物を生物分解処理する微生物の活性不良の問題を効果的に解決することができる、生物活性化の有効成分の提供、これを用いた難分解性有機物含有水の生物処理方法。【解決手段】生物難分解性又は遅分解性の有機物成分を含有するＣＯＤcrが５００ｍｇ／Ｌ以上の水系の生物処理に使用される、生物処理性能を向上させるための生物活性化剤であって、鉄塩を主成分とすることを特徴とする生物活性化剤、及び、該生物活性化剤を用いる難分解性有機物含有水の生物処理方法の提供。【選択図】なし
