| titleOfInvention | Treatment method of chemical nickel wastewater |
| abstract | The invention discloses a method for treating chemical nickel wastewater, which comprises the following steps: s1, adjusting the pH value of the wastewater to 5-6, and then adding H into the wastewater 2 O 2 Carrying out a complex breaking reaction on the solution; s2, adjusting the pH value of the system after the reaction in the step S1 to 6-8, and then adding a mixture of (1-2): 1, a mixed agent of 4-amino-3-mercapto-1, 2, 4-triazole and dimethyldithiocarbamate; s3, adding a flocculating agent into the system after the reaction in the step S2 for flocculation and sedimentation, and then carrying out solid-liquid separation. According to the invention, the nickel in the wastewater is treated by adopting a treatment process of firstly breaking the complex and then chelating the precipitate, the chelating agent is compounded by adopting 4-amino-3-mercapto-1, 2, 4-triazole and dimethyl dithiocarbamate, and the proper pH value condition is matched, so that the removal effect of the nickel in the wastewater is greatly improved, and the precipitate with larger particles is obtained by flocculation and sedimentation, thereby facilitating the subsequent solid-liquid separation. |
