Description
模擬原水1として、市水(野木町水:平均尿素濃度10μg/L、平均TOC濃度0.7mg/L、アンモニア性窒素濃度0.1mg/L未満、平均全残留塩素濃度0.6mg/LasCl2)に試薬尿素(キシダ化学社製)を必要に応じ適量添加したものを用いた。
実施例1において、第一の生物処理手段3を設けなかった以外は、同様にして模擬原水1及び模擬原水2の処理を行った。なお、この際、第二の供給機構7からは、塩化アンモニウムは添加したが、次亜塩素酸ナトリウムの添加は行わなかった。これらの模擬原水1及び模擬原水2の処理水W1の尿素濃度を測定した結果を表1に示す。
4…第二の生物処理手段
7…第二の供給機構(栄養源添加)
W…原水
W1…処理水
