| titleOfInvention | A kind for the treatment of process of chemical nickel plating waste solution containing nitric acid and the treatment system of correspondence |
| abstract | The invention discloses a kind for the treatment of process of the chemical nickel plating waste solution containing nitric acid, it is a kind of eco-friendly treatment process, has considerable integrated environment and economic benefit.The method comprises the following steps: nickeliferous waste liquid filters by (1), removes mechanical impurity; (2) nickeliferous waste liquid is gone out nitric acid by diffusion dialysis membrane sepn; (3) pH regulator is carried out to the nickeliferous waste liquid after mistake film, regulate pH to 3.5 ~ 4.0, then filter; (4) nickeliferous waste liquid is crossed resin and reclaim nickel, then prepare nickelous chloride with the nickel that hydrochloric acid wash-out is adsorbed on resin; (5) add oxygenant to crossing in the waste liquid after resin, high temperature oxidation dephosphorization, then filters, and filters out the precipitation that calcium is formed with phosphoric acid salt, recovery calcium phosphate; (6) in filtrate, add heavy metal capturing agent, reaction 30min ~ 40min; (7) in filtrate, add flocculation agent PAC, PAM and carry out flocculating settling, supernatant liquor qualified discharge afterwards. |
