Method applied to filtration aiding of nickel-containing electroplating sludge acid dissolution leaching slurry

The invention discloses a method applied to the filtration aiding of nickel-containing electroplating sludge acid dissolution leaching slurry. The method comprises the following steps: 1) after nickel-containing electroplating sludge is subjected to acid dissolution, sending into a filtration aiding tank to be homogenized while being stirred so as to prevent the acid dissolution leaching slurry from precipitating; 2) regulating the pH (Potential of Hydrogen) of the acid dissolution leaching slurry to be 3.5-4.5; 3) adding hot water into medicament ox bone glue particles to stand and be dippedfor a period of time; 4) adding the medicament of S3) into the filtration aiding tank in S2), wherein the addition amount of the ox bone glue is controlled to 600-850 ppm; 5) carrying out stirring andhomogenization reaction on mixed slurry obtained in S4), wherein homogenization time is 30-35 min, and constant temperature is 40-60 DEG C; 6) carrying out solid-liquid separation on the mixed slurry, enabling separated filtr
