Rare earth metal production waste liquid treatment method and device thereof

Abstract

The invention discloses a rare earth metal production waste liquid treatment method and a device thereof, and belongs to the technical field of rare earth metal waste liquid treatment, the rare earth metal production waste liquid treatment method and the device can effectively improve the oil stain adsorption capacity, through the arrangement of filter sand, the water tension is increased, the oil stain tension is reduced, oil dirt can easily penetrate through fine gaps between filtering sand, the oil dirt penetrates through a sealing film to be guided into the oil storage hemisphere through guidance of an introduced cotton thread, the oil dirt storage sealing capacity is remarkably improved, and after the adsorption ball adsorbs a certain amount of oil dirt, the quality of the upper hemisphere and the quality of the lower hemisphere are changed. Meanwhile, through arrangement of a saturation triggering mechanism, when a certain amount of oil dirt is stored in the oil storage funnel, the guiding effect of a triggering guiding line can be triggered, the floating light ball is made to be separated from the balance weight ball and float in the air, and a technician is prompted to recycle the device.

Description

technical field [0001] The invention relates to the technical field of rare earth metal waste liquid treatment, and more specifically, relates to a method and device for treating rare earth metal waste liquid production. Background technique [0002] Rare earth metals, also known as rare earth elements, are the general term for the 17 elements of scandium, yttrium, and lanthanide in group IIIB of the periodic table of elements, and are often represented by R or RE. From the discovery of the first rare earth element yttrium in 1794 to the discovery of the natural rare earth element promethium in 1972, it took 178 years for people to find all 17 rare earth elements in nature. The luster of rare earth metals is between that of silver and iron. The chemical activity of rare earth metals is very strong, and rare earths have the reputation of "industrial vitamins". Now it has become an extremely important strategic resource. [0003] In the rare earth metal extraction process, ...

Problems solved by technology

[0004] However, the existing oil pollution adsorption device has poor adsorption capacity for oil pollution. During the adsorption process, the moisture around the oil pollution will be absorbed together, which takes up a large amount of oil pollution storage capacity and reduces the oil pollution treatment efficiency. After it is full, it cannot serve as a reminder, so that the staff cannot collect the oil pollution adsorption device in time, which not only greatly reduces the treatment efficiency of oil pollution, but also reduces the oil pollution adsorption capacity of the device after soaking for a long time, causing oil pollution to leak. Therefore, a kind of rare earth metal production waste liquid treatment method and device are proposed
