Problems solved by technology

At present, most of the treatment of contrast agent mother liquor adopts evaporation and crystallization process. Due to the high content of organic matter in wastewater, organic iodine and salt cannot be separated during evaporation, and it is difficult to produce crystallized salt. In addition, multi-effect evaporators cannot be used, and kettles can only be used. Evaporation, high operating costs

Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] Such as figure 1 As shown, the present invention provides a contrast agent mother liquor organic iodine recovery device, comprising a pretreatment unit 1 for pretreatment of the contrast agent mother liquor, a desalination preconcentration unit 2 connected to the pretreatment unit 1, and a desalination preconcentration unit 2 connected concentration unit 3, brine tank 4 and organic iodine solution tank 5.

[0041] Wherein, the separated monovalent brine in the desalination pre-concentration unit 2 enters the brine tank 4 , and the treated monovalent brine in the concentrated desalination unit 3 also enters the brine tank 4 .

[0042] When the liquid in the desalination pre-concentration unit 2 meets the first predetermined condition, the desalination pre-concentration unit 2 and the concentration unit 3 are connected, so that the feed liquid in the desalination pre-...

Abstract

The invention relates to a contrast agent mother liquor organic iodine recovery device, relates to the technical field of water treatment, and aims to solve the problem of enrichment and recovery of contrast agent mother liquor organic iodine. According to the contrast agent mother liquor organic iodine recovery device, organic iodide and saline water can be effectively separated through a membrane method process, enriched organic iodine can be further recycled, the separated saline water can be further subjected to deepening treatment, and the problems existing in a traditional crystallization process can be thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a device for recovering organic iodine from mother liquid of contrast medium. Background technique [0002] During the treatment of contrast agent mother liquor wastewater, because it contains organic iodine, the precipitation of iodine elemental substance will destroy the biochemical system flora, which is not conducive to the operation of the biochemical system. At the same time, macromolecular organic matter is also difficult to biochemically treat. Therefore, organic iodine in enriched wastewater is A key question. Organic iodine can be effectively separated from other waste water through enrichment, and the enriched organic iodine can be recycled for further resource utilization, waste water can be reused after desalination treatment, and salt can be further resource treatment after evaporation and solidification treatment. At present, most of the treatment of contr...
