Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing:
[0027] In the picture:
[0028] as attached figure 1 shown
[0029] A method for recovering P507 from raffinate wastewater specifically comprises the following steps:
[0030] S101: Collect the raffinate waste water through a waste water bucket, then introduce it into the waste water tank, determine the weight of the raffinate waste water, and add a filter medium with a weight of 100g-150g;
[0031] S102: Stand still and stir the raffinate wastewater with the filter medium added to make the ingredients mixed, the stirring can be carried out with a stirrer, or manually with a stirring rod, until it is fully mixed and kept at room temperature;
[0032] S103: Stand still until the tiny oil particles aggregate and float on the surface of the mixed liquid. You can observe the floating situation of the tiny oil particles in real time through the observation window. You can sti...

The invention provides a method for recovering P507 from extraction raffinate wastewater and belongs to the field of P507 recovery from extraction raffinate wastewater. The method for recovering P507from extraction raffinate wastewater comprises the specific steps that the extraction raffinate wastewater is collected and guided into a wastewater tank, a filtering medium is added, to make tiny oilparticles polymerized and floating on the surface of a material; standing is performed, and suspending organic matter is recovered by adopting a vacuum device after oil-water layering; P507 recyclingis achieved through squeezing of a plate-and-frame filter press. The extraction agent P507 is effectively recovered from extraction raffinate wastewater, the extraction agent consumption is reduced,the treatment cost for follow-up wastewater is also reduced, and stable wastewater up-to-standard discharge is well guaranteed.
Description
technical field [0001] The invention belongs to the technical field of methods for recovering P507 from raffinate wastewater, in particular to a method for recovering P507 from raffinate wastewater. Background technique [0002] The raffinate waste water produced in the extraction workshop enters the wastewater treatment system after being degreased by the existing oil separation device. The degreasing efficiency of the existing oil separation device is not very good, so that the degreasing waste water entering the waste water treatment system also contains tiny oil particles , which not only wastes the extractant, but also increases the difficulty of subsequent COD removal in wastewater. [0003] The prior art patent announcement number CN105152388A discloses a method for advanced treatment and recovery of raffinate wastewater from nickel and cobalt production enterprises. Pump and filter device, the first and second adsorption stirring tanks are equipped with agitators, t...
