description The invention belongs to the field of waste acid treatment and particularly discloses a method for increasing the concentration of titanium dioxide waste acid. The invention aims to solve problems ineffective increase of the concentration of titanium dioxide waste acid and reduction of production cost. According to the method for increasing the concentration of the titanium dioxide waste acid, agas-liquid reactor comprising at least three sub-reactors which are sequentially arranged from a low grade to a high grade is selected as treatment equipment to realize sufficient reaction of the titanium dioxide waste acid with acidolysis tail gas, thereby achieving the purpose of increasing the concentration of the titanium dioxide waste acid. According to the invention, production efficiency can be effectively improved; the titanium dioxide waste acid can absorb acid mist and sulfide in the acidolysis tail gas, so the concentration of the titanium dioxide waste acid is increased; more watervapor can be generated by
