[0002] The composition of chemical nickel wastewater is relatively complex, mainly nickel, hypophosphite, phosphite and organic matter, and chemical nickel wastewater contains complexes. A large amount of nickel exists in the form of complexes, which is difficult to remove by forming nickel hydroxide precipitation. Therefore, the chemical nickel wastewater needs to be decomplexed first to convert the nickel into ionic nickel ions, and then removed by forming hydroxide precipitation. However, due to the high nickel and phosphorus contents in chemical nickel wastewater, the treatment of chemical nickel wastewater is difficult and costly, and the nickel and phosphorus contents of the treated effluent are difficult to stably meet the emission standards, and both nickel and phosphorus will cause harm to the environment.
