Abstract
본 발명은 악화된 폐쇄성 수역의 수질 및 바닥 침전물의 개질을 도모하 수 있는 개선제를 제공한다. 고토계 분말 과립체 원료로 구성되는 재료로서, 그 크기가 입자 직경으로 20㎜ 이하이고, 또한 물안에 투입후 자기 붕괴하여, 투입 60분 후에 있어서의 0.1㎜ 이하의 입자가 10중량% 이상인 것을 특징으로 한다.The present invention provides an improver capable of modifying the water quality and bottom sediment in deteriorated closed waters. A material composed of a high-molecular powder granule raw material, the size of which is 20 mm or less in particle diameter and self-collapses after being introduced into water, wherein particles having a diameter of 0.1 mm or less after 60 minutes of incorporation are 10% by weight or more. It is done.
