The invention discloses a
resource utilization zero-emission recycling process method of a
chemical waste nickel liquid. The
resource utilization zero-emission recycling process method is characterized by comprising the following steps: I, concentrating and separating the
chemical waste nickel liquid, namely, adjusting the pH value of the
chemical waste nickel liquid to be 3-5, performing low-temperature negative pressure
evaporation concentration, and rising the temperature to 95-110 DEG C, wherein the negative pressure condition is minus 0.09 - minus 0.1MPa and the boiling temperature is not greater than 70 DEG C; II, separating
sodium sulfate by an acid solution, namely, performing slow soaking
dissolution on chemical nickel residues by a
sulfuric acid solution in stirring so as to obtain a
sulfuric acid leaching agent; after sufficient cooling, and performing
filtration to obtain filtrate and
sodium sulfate crystal; III, extracting and separating nickel
sulfate, namely, adding
ethanol into the filtrate, leaving to stand to layer, and performing
solid-separation separation so as to obtain nickel sulfate
solid for resource recycling and reuse; IV, recycling
ethanol. By adopting the
resource utilization zero-emission recycling process method disclosed by the invention, the chemical
solid nickel waste can be completely recycled, the requirements of environment-friendliness of waste liquid recycling and
zero emission are met indeed, and the required social environment capacity is greatly reduced.
