▎ 摘　　要

NOVELTY - river heavy metal sediment adsorption column, comprising a lower part sunk end and an upper part of the absorbing end, the countersunk end is a tip-shaped metal body for inserting and fixing in the riverway and the absorption end is formed on the countersunk end, comprising a shell and formed in the shell of the adsorption column, the shell is a ceramic shell and uniformly distributed micro-pore surface, in addition, with a gap interlayer is set between the shell and the adsorption column and the gap in the interlayer is provided with a micro-pore filtering membrane from the housing between the adsorption column; porous sorbent particles filling layer and a graphene film layer. The utility model is used for adsorbing river heavy metal sludge in the heavy metal and organic matter, has low energy consumption, low cost, wide application range, high processing efficiency, simple operation and so on.
