Description
生物膜濾過処理装置３としては、ダイワ工業株式会社製の「ダイワエース（登録商標）」を使用するとよい。ダイワエース（登録商標）は、浮遊濾材３２の単位体積当たりの比表面積が大きいことにより懸濁物質の捕捉能力に優れており、懸濁物質の除去性能が高いという利点を有している。また、浮遊濾材３２の比表面積が大きいことにより、浮遊濾材３２の表面の総微生物量も多くなるので、ＳＳ、ＢＯＤ、ＣＯＤの除去性能が高いという利点もある。さらに、浮遊濾材３２が水よりも軽いポリプロピレンからなることにより流動性がよく目詰まりしにくいという利点も有している。したがって、逆洗頻度及び逆洗水量が少なくて済むので、作業効率やコストの面で好適である。 As the biofilm filtration apparatus 3, “Daiwa Ace (registered trademark)” manufactured by Daiwa Industry Co., Ltd. may be used. Daiwa Ace (registered trademark) has the advantage that the suspended filter medium 32 has a large specific surface area per unit volume, so that it has an excellent ability to trap suspended substances and has a high ability to remove suspended substances. In addition, since the specific surface area of the floating filter medium 32 is large, the total amount of microorganisms on the surface of the floating filter medium 32 is also increased, which has an advantage of high SS, BOD, and COD removal performance. Furthermore, since the floating filter medium 32 is made of polypropylene that is lighter than water, it has an advantage that it has good fluidity and is not easily clogged. Therefore, the backwashing frequency and the amount of backwashing water can be reduced, which is preferable in terms of work efficiency and cost.
