上向きの混合溶液流ｅを発生させる。First, the sewage d is supplied to the sewage treatment tank 21 and is oxidized by microorganisms in the activated sludge in the tank 21. On the other hand, the air bubbles discharged from the aeration pipe 23 to which aeration air is supplied by the blower 24 supply oxygen for growth to the microorganisms, and
Generate an upward mixed solution flow e.
さらに、この槽２１内に塩化第２鉄や硫酸バンドなどの
凝集剤ｆが投入されＣＯＤや色成分などを凝集させる。Furthermore, a flocculant f such as ferric chloride or sulfuric acid is added to the tank 21 to flocculate COD, color components, and the like.
ここで、ポンプ２６に祉りろ退部２５を働かせて、ろ退
部２５を上向きに通過する混合溶液２２をろ過して清澄
水を取り出す。Here, the pump 26 is operated to operate the filtering and retracting section 25, and the mixed solution 22 passing upward through the filtering and retracting section 25 is filtered to take out clear water.

設備を簡素化することができる。Therefore, in one sludge tank 21, oxidation treatment of sewage by microorganisms and substances and coagulation treatment for removing COD, color components, etc. in the sewage can be performed simultaneously, and the mixed solution 22 treated with these can be transferred to the filtration section. 25, the wastewater treatment equipment can be simplified.
なお、このとき、凝集剤を投入しすぎると、微生物が死
滅して汚水の酸化処理ができなくなるので、この汚水処
理装置２７は凝集剤を投入すべき量が比較的少ないとき
のみ有効となる。Note that if too much flocculant is added at this time, microorganisms will die and the sewage cannot be oxidized, so the sewage treatment device 27 is effective only when the amount of flocculant to be added is relatively small.
