Abstract
Description
生物担体としては、活性炭が好適である。
酸素含有ガスは空気、酸素富化空気、純酸素等、酸素を含む気体であればよい。通気する気体はフィルターを通過させて微細粒子を予め除去することが望ましい。
被処理水の反応槽内の流速はLV7m/hr以上とし、TOC濃度20mg/L以下の低濃度排水では処理水を循環せず、ワンパスで処理することもできる。一過式で処理するとポンプ動力削減することができる。
槽負荷0.5〜4kg−TOC/m3/dayとなるように滞留時間を設定するのが好ましい。
ブロワ26は、吐出風圧が水深からくる水圧以下のもので十分である。但し、配管等の圧損以上であることは必要である。通常、配管抵抗は1〜2kPa程度である。
