| Abstract: |
| This article has carried out a detailed study on the process of coalescing and removing mercury from pollutant acid, and investigated the influence of coalescing agent addition, temperature, mixing time, air flotation time and acidity on the mercury removal effect. According to the above test, it is recommended The process conditions are: M201 reagent concentration 50g/L, addition amount 6mL/L-soil acid solution, temperature at room temperature, mixing time 5min, air flotation time 10min, aeration rate 0.1L/min, acidity 33.67 g/L, deodorization The mercury rate can reach more than 99%, and the residual mercury content is 2mg/L; the arsenic removal rate is 31.56%, and the residual arsenic content is 21.9 mg/L; arsenic and mercury can be separated well, and mercury can be removed in one step. |
