Na tango oyo, ba méthodes ya traitement physicochimique na biochimique ezali kaka direction ya recherche principale ya mayi ya bosoto ya accélérant, pe ezali pe technologie ya minene ya traitement ya mayi ya bosoto oyo ezuami na ba entreprises accélérantes na mboka pe na poto.
1 Traitement physico-chimique .
Physicochemical treatment methods mainly include extraction, distillation and evaporation, coagulation, air floatation, adsorption, etc.These technologies are mainly in the laboratory research stage, and the corresponding research has a good effect on the removal of some pollutants in the waste water, these directional removal function also limited their industrial applications.Du huiling et al. [2] and bayer et al. [2] showed that the Méthode ya extraction ezuaki effet ya bolongoli malamu na ba composés organiques spécifiques na mayi ya bosoto ya promoteur, kasi ebongoli te teneur ya mungwa ya mayi ya bosoto, mpe quantité ya agent ya extraction ezalaki monene, ememi pollution secondaire mpe bongo na.distillation mpe évaporation ekoki kokitisa teneur ya ba salts inorganiques mpe ba composés organiques na mayi ya bosoto [{{7}], mpe na yango ezali na ba produits ya likolo, mpe na mayi ya likolo mpe na mayi ya likolo mpe na mayi ya likolo mpe na mayi ya likolo, mpe na mayi ya moke mpe na mayi ya likolo mpe na mayi ya monene mpe ezali na yango mpo na ko s’appulait mpo na ba produits ya likolo oyo ezali na yango mpo na ba coûts ya likolo mpe ya mayi ya likolo mpe ya mayi ya likolo mpe ya mayi ya likolo mpe ya mayi ya monene mpe ezali na yango. water.Flocculation test [5] shows that conventional flocculants have poor effect in the direct treatment of high concentration accelerator wastewater. Although diatomite compound coagulant [6] significantly improves the effect of coagulation pretreatment accelerator wastewater, it is difficult to prepare such coagulant.Adsorption method has a better effect on the removal of dissolved organic matter that is difficult to be oxidized and degraded by both conventional biological and chemical oxidation.Studies have found that activated carbon, a common adsorbent, has a better adsorption effect on wastewater with low COD concentration [7]. In addition, due to its high price, it is not economical to pretreat wastewater with high concentration, and it is generally used as the effluent control index for subsequent treatment.
2 Bosalisi ya biloko ya chimique .
Chemical treatment methods mainly include chemical precipitation, chemical oxidation and micro-electrolysis.Chemical oxidation is a method of oxidative degradation and removal of organic pollutants in wastewater.Several commonly used oxidants are Fenton reagents, chlorine oxidants and ozone.Studies [8-11] have found that these oxidants do not have a high ability to remove COD, and the amount of reagents added is large, the operation cost is high, and a large number of by-products will be produced after ozonation [12].Iron carbon micro-electrolysis process is simple, can achieve the purpose of "waste to waste".However, the disadvantage of this method is that pH needs to be adjusted before and after the reaction, and a large amount of iron sludge needs to be disposed after Réaction, oyo esali que ba coûts ya traitement ya likolo.yango wana, micro-électrolyse ya carbone-carbone esangani mingi mingi na ba technologies mosusu ya traitement, lokola coagulation mpe oxydation ya Fenton, mpo na kobongisa efficacité ya traitement mpe kokitisa coût ya traitement.
3 Méthode biochimique .
Traitement biologique ezali méthode traditionnelle et économique ya traitement ya mayi ya bosoto organique.Nzokande, mingi ya mayi ya bosoto ya accélérant ezali mpasi mpo na ko traité directement na ba méthodes biochimiques conventionnelles, mingi mingi mayi ya bosoto na mungwa ya likolo, azote ya ammoniac ya likolo mpe ba organiques ya toxique ya likolo, oyo ezali kaka bottleneck ya technologie ya traitement biochimique.
