Abstract

The invention discloses a Sn / Sb-GAC particle. The Sn / Sb-GAC particle is a carrier type Sn / Sb-GAC particle prepared by loading and modifying granular activated carbon with metal ions of Sn and Sb through an impregnation method. The carrier type Sn / Sb-GAC particle serves as a particle electrode, a dimensionally stable anode (DSA) serves as the anode and a titanium plate serves as the cathode to structure a repolarized three-dimensional electrochemical reactor for three-dimensional electrochemical reaction under the action of electrochemical oxidation so that 4-chlorophenol can be degraded into carbon dioxide and water, when applied to treating 4-chlorophenol waste water, the Sn / Sb-GAC particle can achieve a 4-chlorophenol eliminating rate up to higher than 83%. Meanwhile, the Sn / Sb-GAC particle is simple in preparation process, reusable and capable of reducing the treating cost of the 4-chlorophenol waste water and improving the treating efficiency of the 4-chlorophenol waste water.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to the preparation of Sn / Sb-GAC particles and its application in three-dimensional electrochemical reaction treatment of 4-chlorophenol wastewater. Background technique [0002] With the rapid development of petrochemical, plastic, synthetic fiber and other industries, phenolic wastewater generated in production is discharged into nature, causing water pollution and affecting the growth and reproduction of aquatic organisms. Phenol-containing wastewater is a refractory toxic organic substance, and it is also a difficult point in environmental governance. The discharge of phenolic substances is strictly controlled at home and abroad. [0003] The treatment of phenolic industrial wastewater has also become one of the hot research topics. At present, the adsorption method can generally be used for the treatment of wastewater containing phenolic substances, and the adsorbent o...
