SLUDGE SITE STABILIZATION TREATMENT METHOD
PROBLEM TO BE SOLVED: To provide a sludge site stabilization treatment method at low cost, which is capable of performing a processing to solidify sludge which contains harmful heavy metals after absorbing organic toxic substances such as dioxin, and which enables selection of general purpose construction machines used at the site and sludge slurry transport facilities including a dredging pump used in the vicinity of the site, and which carries out a construction site preparation based on determination of the possibility of drainage at the site while preventing dioxin etc. from being flown out, discharged or diffused from the processing site out of the system to prevent expansion of environmental pollution.SOLUTION: The sludge site stabilization treatment method includes: a construction site preparation step to determine the possibility of drainage at the processing site, select applied mixing and stirring means and dispose the same based on the determination; an absorbent and fixation agent adding and stirring processing step to add additive agents to the sludge using an absorbent and fixation agent adding means disposed to the selected mixing and stirring means; and a site-curing step to cure improved soil which is obtained by the absorbent and fixation agent adding and stirring processing at the site or in a vicinity yard.
【課題】有害重金属を含む泥土状ヘドロ内に、ダイオキシン等の有機系の有害物を吸着した上で固化する処理を、現場での汎用の建設機械の選択又は現場近傍での浚渫ポンプを含む泥土スラリー送給設備の選択を可能とし、現場の水抜き可否判断を基礎として施工現場環境事前準備する工程等を施し、処理現場から、系外にダイオキシン等の流出、排出ないし拡散を防止し、環境汚染の拡大を防ぐ安価な工法を提供する。【解決手段】処理対象現場において、水抜き可否判定と該判定に基づく適用混合・撹拌手段を選択して配備する施工現場環境事前準備工程と、前記選択された混合撹拌手段及び当該混合撹拌手段に付設される吸着剤・固化剤添加手段により添加剤をヘドロに添加混入する吸着剤・固化剤混入撹拌処理工程と、前記吸着剤・固化剤混入撹拌処理により得られた改良土を現場又は近傍ヤードで養生する現場養生工程とを含むヘドロ現場安定化処理工法。【選択図】 図１
