Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
nullAs shown in Figure 1，In the present embodiment，The extraction of a kind of amantadine waste water and the system of electrodialysis process，Including the neutralization reaction tank 3 passing sequentially through pipeline communication according to water (flow) direction、Sedimentation tank 7、Extraction equipment 11 and bipolar membrane electrodialysis device 13，Connection sedimentation tank 7 is provided with delivery pump 9 with the pipeline of extraction equipment 11，Extraction equipment 11 is circumscribed with extractant throwing device 12，Neutralize reaction tank 3 and have wastewater collection pond 1 by pipeline communication，Neutralize and be communicated with elevator pump 2 on the pipeline between reaction tank 3 and wastewater collection pond 1，Sedimentation tank 7 is communicated with intermediate pool 8，Intermediate pool 8 connects with delivery pump 9，Extraction equipment 11 is communicated with back extraction device 14，Back extraction device 14 is communicated with extractant medial launder 15，Extractant medial launder 15 connects with extractant throwing device 12，Extractant circulating pump 16 it is communicated with between extractant medial launder 15 and extractant throwing device 12.
Neutralize reaction tank 3 to be used for being neutralized precipitation process, due to diamantane (obsolete) amination waste water complicated components, in addition to containing a large amount of toxic organic compounds, the soluble solids such as the inorganic matter possibly together with high concentration, the existence of these soluble solids is easily caused extractive reaction process and produces emulsion, brings serious impact to two-phase laminated flow.Additionally, the extreme alkaline condition of waste water is also unfavorable for organic efficient extract and separate.Having a large amount of solid sediment during using acid solution regulation amination waste water pH to generate, the precipitation of these soluble solids not only can reduce the content of Pollutants in Wastewater, it is also possible to alleviates the emulsion in follow-up extraction process, accelerates phase process.But owing to amination waste water is strong basicity, pH regulator process needs to consume substantial amounts of acid solution, considerably increases the processing cost of waste water.And bromination waste water is a kind of strongly acid wastewater produced in amantadine production process, its contaminant component and amination waste water also have certain similarity, use in highly acid bromination waste water and the amination waste water of alkalescence, precipitated by the acid-base neutralization of two kinds of waste water, soluble solid and the content of other pollutant in waste water can be reduced, create conditions for follow-up complexometric extraction reaction.
Enter in sedimentation tank 7 neutralizing the reaction tank 3 liquid after neutralization precipitation processes, generation solid sediment is enable to be precipitated, remaining liquid enters in extraction equipment under the effect of delivery pump 9, extractant is made to contact formation complex with Organic substance in solution at extraction equipment inner utilization complexing abstraction, and make Organic substance be enriched with in organic facies, thus isolate target extract.Complexing abstraction technique is simple and convenient to operate, and has the highest selectivity and separation property for the polar organic matter in waste water, and extractant can recycle after back extraction.In the present embodiment, the complex obtained through complex reaction is adamantanamine hydrochloride.
The recovery of extractant and recycling are to determine that can extraction be applied to the key that actual waste water processes.The recycling of regeneration and extract solutes in order to realize extractant, it is contemplated that the recovery of the adamantanamine hydrochloride formed after back extraction, the present embodiment uses HCl solution as the amantadine in strippant back extraction load organic phases.By using the HCl solution of 2.0 mol/L to be obtained in that preferable back extraction effect, in load organic phases, the back extraction efficiency of amantadine can reach 45 ~ 47%.Back extraction adamantanamine hydrochloride out can be back to use in production technology, in order to realizes the recycling of valuables.For investigating the repeatable usability of extractant, under conditions of oil/water is in a ratio of 1: 1, use P204: n-octyl alcohol=3: the compounding extractant of 2 has carried out repeatedly extraction and back extraction test to diamantane (obsolete) amination waste water, the effect of extracting of amantadine in waste water is the most significantly reduced by the extractant after regeneration, the extraction efficiency of amantadine is all more than 98%, P204/ n-octyl alcohol compounds extractant process amantadine pharmacy waste water and shows good stability, can repeatedly use.
Bipolar membrane electrodialysis is a kind of novel membrane separation technique, under the effect of DC electric field, water is directly dissociated into H+ and OH-by Bipolar Membrane, then by the electrodialysis system formed with anions and canons exchange membrane, salt can be converted in the case of not introducing new component corresponding bronsted lowry acids and bases bronsted lowry.Compared with traditional electrodialytic technique, this technology has that operating cost is low, no coupling product produces, and can all reclaim bronsted lowry acids and bases bronsted lowry, is a kind of environmentally friendly water technology.Complexing abstraction and bipolar membrane electrodialysis technology are used for the process of amantadine pharmacy waste water, not only with pollution abatement and the difficulty processed further, and the recycling of valency pollutant can be capable of.
The work process of the present embodiment is as follows: after the amination waste water produced in amantadine production process and bromination waste water being collected by wastewater collection pond, acid-base neutralization is carried out to remove partial solubility solid and Organic substance in neutralizing reaction tank, then complexing abstraction is used to separate and recover the valuables such as the amantadine in waste water in extraction equipment, bipolar membrane electrodialysis device is used to reclaim bronsted lowry acids and bases bronsted lowry, to realize the collaborative process of amination waste water and bromination waste water, extraction back loading extractant carries out regeneration in back extraction device and reuses.
