Abstract

The invention discloses Sn / Sb-Mn-GAC particles. The particles are supported Sn / Sb-Mn-GAC particles prepared by supporting modified granular activated carbon onto metal ions such as Sn, Sb and Mn through an impregnation method. The method comprises the following steps: taking the supported Sn / Sb-Mn-GAC particles as a particle electrode, taking a dimensionally stable anode DSA as an anode, taking atitanium plate as a cathode, constructing a bipolar type three-dimensional electrochemical reactor, carrying out a three-dimensional electrochemical reaction under an electrochemical oxidation effect,and finally degrading 4-chlorophenol into carbon dioxide and water. The 4-chlorophenol wastewater is treated by using the Sn / Sb-Mn-GAC particles, so that the removal rate of the 4-chlorophenol can reach 99% or higher. Meanwhile, the particle preparation process is simple, the particles can be repeatedly used, the treatment cost of the 4-chlorophenol wastewater is greatly reduced, and the treatment efficiency of the 4-chlorophenol wastewater is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to the preparation of Sn / Sb-Mn-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 adsorben...
