| titleOfInvention | Method for self-cleaning arsenic removal in waste acid through ultrasonic waves |
| abstract | The invention relates to a method for removing arsenic by ultrasonic self-cleaning in waste acid, which can achieve the aim of efficiently removing arsenic by only utilizing an ultrasonic device which is independently developed to carry out ultrasonic strengthening treatment on the waste acid without adding any reagent, and comprises the following specific steps: adding ultrasonic wave into the waste acid for strengthening, reacting for a certain time to generate precipitate, and performing solid-liquid separation to obtain filtered solution and precipitate impurities. According to the arsenic removal method provided by the invention, arsenic impurities in the waste acid can be efficiently removed, the process is simple, the cost is greatly reduced, and meanwhile, the treated acid and water can be recycled to a zinc oxide smoke dust recovery working section, so that the pollution to the environment is reduced; meanwhile, waste of a large amount of acid and water in the waste acid is avoided, no arsenic removal reagent is added, the treatment cost is reduced, other impurities are not introduced, and the method is energy-saving and environment-friendly. |
