| titleOfInvention | Praseodymium oxide production waste liquid recovery treatment method |
| abstract | The invention discloses a praseodymium oxide production waste liquid recovery processing method, which belongs to the technical field of rare earth production, and comprises the following steps: the method comprises the steps of conducting primary filtration on production waste liquid, removing oil stains in the waste liquid, placing primary filtrate into a stirring tank, adding a heavy metal treatment agent, removing precipitates to obtain supernatant A, adding a biosurfactant, removing precipitates to obtain supernatant B, filtering by adopting a flat ultrafiltration membrane to obtain fine filtrate, conducting evaporation filtration treatment, and discharging the waste water after the evaporation filtration treatment after detection. According to the waste liquid treatment process, the praseodymium oxide production waste liquid is efficiently treated through the procedures of primary filtration degreasing, heavy metal treatment agent treatment, biological active agent treatment, steaming filtration treatment and the like, pollutants and heavy metal substances in the waste liquid can be sufficiently removed, the treatment effect is good, the efficiency is high, the treated waste water can reach the discharge standard, the process flow is simple and easy to operate, and the requirement of large-scale waste water treatment is met. |
