The utility model discloses a novel wastewater light component removal tower structure which comprises a light component removal tower, the bottom end of the light component removal tower is connected with a reboiler, the light component removal tower is in the shape of a cylindrical tank, the light component removal tower is formed by sequentially connecting a top shell, an adsorption shell, a plurality of slow flow shells and a bottom shell from top to bottom, the top shell is in the shape of a cylindrical shell with an opening in the bottom end, and the adsorption shell is connected with the slow flow shells. The adsorption shell and the flow slowing shells are each in a cylindrical shell shape with openings in the upper end and the lower end, and the bottom shell is in a cylindrical shell shape with an opening in the top end. The edge of the bottom end of the top shell, the edges of the two axial ends of the adsorption shell, the edges of the two axial ends of the slow flow shell and the edge of the top end of the bottom shell are all provided with connecting flanges and are in bolt connection through the connecting flanges. An adsorption assembly is arranged in the adsorption shell, and a flow guide part is arranged below the adsorption assembly; a plurality of blocking pieces are arranged in the flow slowing shell and arranged at equal intervals in the axis direction of the flow slowing shell.

The application provides a system treatment process for fluorine-containing wastewater, which comprises the following steps: a fluorine-containing wastewater treatment process, a sludge treatment process, a defluorination filter material regeneration process and a sludge waste liquid treatment process. The system treatment process for fluorine-containing wastewater has the advantages of low sludge yield, low flocculant consumption, low treatment cost, high adsorption capacity, greatly prolonged adsorption time of the adsorbent, reduced regeneration frequency, no discharge of regeneration liquid, and effectively solved problem of difficult treatment of by-products of traditional treatment processes.
