| titleOfInvention | Method for recycling high-value materials from chemical wastewater |
| abstract | The invention belongs to the technical field of environmental protection wastewater treatment, and particularly relates to a method for recycling high-value materials from chemical wastewater, which at least comprises the following steps: the method comprises the steps of adjusting the pH of original wastewater, performing primary membrane separation treatment on the wastewater after the pH adjustment, performing secondary membrane separation treatment on filtrate, combining secondary membrane concentrated solution and primary membrane concentrated solution, performing pre-precipitation, removing sludge for dehydration, performing tertiary membrane separation treatment on secondary membrane filtrate, performing evaporation and concentration on tertiary membrane concentrated solution, and drying the concentrated solution after the evaporation and concentration to obtain an organic phase product. And (3) removing the resin adsorption process from the third-stage membrane filtrate for adsorption, removing the fourth-stage membrane process from the filtrate after adsorption for concentration, removing evaporation crystals from the filtrate after the filtrate is subjected to fourth-stage membrane concentration to obtain semisolid strong brine, and removing centrifugal separation from the strong brine to obtain solid salt. The process can ensure that 100 percent of wastewater reaches the standard and is discharged, more than 95 percent of valuable materials in the wastewater can be recovered, the purity of the recovered materials can reach more than 90 percent, and the recovered inorganic salt is solid sodium chloride. |
