SEDIMENT DREDGING FLOCCULATION TREATMENT SYSTEM AND CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a sediment dredging flocculation treatment system that dredges a floating mud layer and a deposit surface layer by using a pump without disrupting a deposit and generating turbidity with the work, efficiently performing solid-liquid separation treatment of muddy water generated in large quantities to the dredging sediment, and enabling re-use or land temporary storage of the enriched flocculated sediment containing organic matter.SOLUTION: A sediment suction dredging device A (submersible pump with breaker) mounted in a back hoe C is operated by the positional information of GPS and the water depth information of the ultrasonic wave depth gauge, and the suction removal of the floating mud layer is managed along with the thin layer dredging. The muddy water generated in large quantities is efficiently treated by the solid-liquid separation treatment using a high-performance mineral hydrophobicity flocculating agent and a sediment flocculation precipitation separation device M of a voluntary design. The coagulum concentrated by the solid-liquid separation is charged in a receiving bag mounted with a filtration inner bag having a filtering function, and furthermore the decrease of capacity by filtration is promoted. A low-cost device and a processing technology are provided which are constituted of the thin layer dredging, the flocculation treatment and solid-liquid separation, and the natural dewatering in the receiving bag.
【課題】底質を乱たり作業に伴う濁りを発生させずに浮泥層と底質表層をポンプ浚渫し、浚渫底泥に対し大量に発生する泥水を効率良く固液分離処理し、有機物も含めて濃縮した凝集底泥を再利用或いは陸上仮保管できる底泥浚渫凝集処理システムを提供する。【解決手段】ＧＰＳの位置情報および超音波測深器の水深情報により、バックホーＣに取付けた底泥吸引浚渫装置Ａ（破砕器付水中ポンプ）を操作し、浮泥層の吸引除去とともに薄層浚渫を管理する。大量に発生する泥水は高機能無機質疎水性凝集剤と自主設計の底泥凝集沈殿分離装置Ｍにて効率良く固液分離処理を行う。固液分離により濃縮した凝集体は、フィルタリング機能のある濾過内袋を装着した収容バックに投入され、更に濾過による減容化を促進する。薄層浚渫から凝集処理と固液分離および収容バックでの自然脱水からなる低コストな装置と処理技術である。【選択図】図１
