Abstract
【解決手段】アナモックス菌を少なくとも含有し、水理的滞留時間(hydraulic retention time)を2時間以内とした場合において、窒素除去率80%以上の窒素除去能力を備えた混合微生物。この混合微生物はアナモックス菌を含有するため、廃水中などに含有するアンモニア性窒素及び亜硝酸性窒素を窒素ガスに変換する。これにより、廃水中から窒素を除去できる。このアナモックス菌又はアナモックス汚泥を集積培養することにより、窒素負荷5〜10kg/m3/dayで処理できるため、廃水中などに含有する窒素を、比較的大量、短時間、かつ効率的に処理できる。従って、この混合微生物を用いることにより、高度かつ大量な廃水処理が可能となる。
【選択図】図5
