Abstract

The invention relates to a processing system for extracting organic matters in wastewater by rare earth elements, and a processing method for extracting the organic matters in the wastewater by the rare earth elements with application of the system. According to the invention, oxidation efficiency in extraction of the organic matters in the wastewater with the rare earth elements is increased, so processing efficiency is increased, secondary pollution caused by residual ozone is solved, and thus field applicability of an ozone oxidation processing technology is further enhanced.

Description

technical field [0001] The invention relates to a system for treating organic matter in rare earth element extraction wastewater and a method for treating organic matter in rare earth element extraction wastewater using the system. Background technique [0002] Rare Earth Elements (Rare Earth Elements) is a collective name for 17 elements including 15 lanthanum (lanthan) elements with atomic numbers 57 to 71, scandium (Sc) with atomic number 21, and yttrium (Y) with atomic number 39. [0003] In the process of extracting such rare earth elements, waste water containing organic matter, etc. is generated, and many studies have been made to treat organic matter contained in waste water, and ozone, penton, and ozone have been developed as energy utilization treatment methods and chemical treatment methods. / H 2 o 2 , ozone / UV, ozone catalyst and other various types of high oxidation treatment technology. [0004] Among the high oxidation treatment processes, the most applicab...

Problems solved by technology

[0011] In order to solve the above problems, the object of the present invention is to provide a novel rare earth element extraction organic matter treatment system in the wastewater, that is, the system introduces the organic matter treatment system in the rare earth element extraction wastewater by introducing the hydrodynamic cavitation (hydrodynamiccavitation) process In this way, the injection concentration of ozone is reduced, and the generation of OH radicals with strong oxidizing power is increased. In addition, the solubility of ozone gas is increased by miniaturizing the bubble size of ozone, thereby increasing the oxidation ability, so it can not only increase Oxidation efficiency of organic matter, also solves the problem of residual ozone and secondary pollution caused by ozone
