Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 汚水中に含有した磁性粒子の処理能力が大き く、永久磁石片４４に吸着した磁性粒子を確実に排出す ることができる汚水処理装置２０を提供する。 【構成】 下部に汚水の輸送管２８と上部に処理水の排 水用トラフ３６が配設されて汚水が上向流に流れる汚水 処理槽２２と、汚水処理槽２２の汚水中に水没配置され 回転軸２６に所定の間隔をもって並列装架された複数の 磁気円板２４と、磁気円板２４の表面に同心状に配設さ れた複数の永久磁石片４４と、汚水処理槽２２の汚水中 に水没配置されて永久磁石片４４の表面に傾斜して当接 された板状のレーキ４８と、汚水処理槽２２の汚水中に 水没配置されてレーキ４８の上方に集泥ガイド５０が形 成された汚泥排出管５４と、から構成する。 (57) [Summary] [Object] To provide a sewage treatment apparatus 20 having a large treatment capacity for magnetic particles contained in sewage and capable of reliably discharging the magnetic particles adsorbed on the permanent magnet pieces 44. [Structure] A sewage treatment tank 22 in which a sewage transport pipe 28 is disposed at a lower portion and a treated water drainage trough 36 is disposed at an upper portion to cause sewage to flow upward, and a sewage treatment tank 22 is submerged in wastewater and rotated. A plurality of magnetic discs 24 mounted in parallel on the shaft 26 at a predetermined interval, a plurality of permanent magnet pieces 44 concentrically arranged on the surface of the magnetic disc 24, and in the wastewater of the wastewater treatment tank 22. A plate-shaped rake 48 that was placed in water and abutted on the surface of the permanent magnet piece 44 in an inclined manner, and a mud collecting guide 50 formed above the rake 48 that was placed in water submerged in the sewage treatment tank 22 were formed. And a sludge discharge pipe 54.
