The invention belongs to the technical field of sludge treatment, and particularly relates to a stabilization method for heavy metal in sludge and a special device. The special device comprises a ship body, a treatment box and a motor, wherein the interior of the ship body is fixedly connected with the treatment box; a treatment cavity is formed in the treatment box; an inlet is formed in the side surface of one side of the treatment box; a mud inlet pipe is fixedly connected into the inlet, and the other end of the mud inlet pipe is located at the bottom of the ship body; an outlet is formed in the side surface of the other side of the treatment box; the interior of the outlet is fixedly connected with a sludge outlet pipe; a mounting plate is fixedly connected to the inner top surface of the treatment box; and the bottom surface of the mounting plate is fixedly connected with first spray heads which are uniformly arranged. According to the invention, the efficient purification treatment of the sludge is effectively realized, the efficient stabilization of unstable heavy metal ions in the river bottom sludge is ensured, the sludge is disinfected, the treated sludge can be directly guided back to the river bottom, the sludge does not need to be cleared and transported, and the workload of sludge treatment is reduced.

    本发明属于污泥处理技术领域,具体的说是一种污泥重金属稳定化方法及专用装置,包括船体、处理箱和电机,所述船体的内部固连有处理箱;所述处理箱的内部开设有处理腔;所述处理箱的一侧侧面开设有进口;所述进口的内部固连有进泥管,且进泥管的另一端位于船体的底部;所述处理箱的另一侧侧面开设有出口;所述出口的内部固连有出泥管;所述处理箱的内部顶面固连有安装板;所述安装板的底面固连有均匀布置的第一喷头;通过本发明有效的实现了污泥的高效净化处理,保证了河底污泥中不稳定的重金属离子得到高效稳定化,同时对污泥进行消毒处理,并且处理后的污泥会直接导回到河底,无需对污泥进行清运,减轻污泥处理的工作量。
