| titleOfInvention | A kind of pickling method for turmeric hydrolysis filter residue |
| abstract | The invention discloses an acid washing method for turmeric hydrolysis filter residue, which belongs to the acid washing technology and comprises the following steps: (1) cleaning the first batch of filter residues, collecting and detecting the acid washing water for each cleaning, and ending with the last acid washing water The pH value is 6.0 to 7.0; (2) Wash the next batch of filter residues in sequence from the second to the last acid wash water of the previous batch of filter residues, and collect the acid wash water separately; (3) The last wash in the detection step (2) If the pH value of the acid water is 6.0 to 7.0, proceed to step (4), if it is less than 6.0, then wash with clear water until the pH value of the last pickling water is 6.0 to 7.0, and collect each pickling water for cleaning; (4) Repeat step (2) and step (3). The present invention uses the pickling water of the previous batch of filter residues as the cleaning water of the next batch of filter residues, thereby improving the utilization of water resources, reducing the waste of water, and reducing the amount of pickling water as a whole, which is beneficial to the later pickling Reduced water treatment costs. |
