Ko’ágã, umi método de tratamiento fisicoquímico ha bioquímico ha’e gueteri dirección investigación principal umi aguas residuales acelerantes, ha avei ha’e pe tecnología principal tratamiento de aguas residuales oadoptáva umi empresa acelerante tetãme ha tetã ambuére.
1 Tratamiento Físicoquímico rehegua .
Umi método tratamiento fisicoquímico rehegua oguereko principalmente extracción, destilación ha evaporación, coagulación, flotación aérea, adsorción, etc.ko’ã tecnología oĩ principalmente etapa de investigación laboratorio-pe, ha pe investigación correspondiente oreko efecto porã ojeipe’ávo algunos contaminantes y residual-pe, ko’ã función de remoción direccional avei umi aplicación industrial . the extraction method achieved a better removal effect on specific organic compounds in the promoter wastewater, but did not change the salt content of the wastewater, and the amount of extraction agent was large, bringing secondary pollution and so on.Distillation and evaporation can reduce the content of inorganic salts and organic compounds in wastewater [3-4], but this method has high energy consumption and operation cost, and is suitable for treating wastewater with high salinity and small amount of 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 Oñembyai mokõive oxidación biológica ha química convencional.Estudios ojuhu carbono activado, adsorbente común, oreko efecto adsorción iporãvéva umi y ky'a orekóva baja concentración COD [7]. además, péva hepyeterei rupi, ndaha'éi económico aguas residuales orekóva pretreat índice de alta consición {16 16 ary, ha it generalmente ojeporu índice {16.
2 Ñepohano químico rehegua .
Umi mba’e ojejapóva tratamiento químico-gui ha’e principalmente precipitación química, oxidación química ha micro-electrólisis.Oxidación química ha’e peteĩ método degradación oxidativa ha ojeipe’a umi contaminante orgánico y ky’ápe.Hetaiterei ojeporu jepi oxidante ha’e reactivo fenton, oxidante cloro rehegua ha ozona {4} {4}. 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 Opa rire pe reacción, osẽva costo de tratamiento yvate.Upévare, microelectrólisis hierro-carbono rehegua oñembojoaju generalmente ambue tecnología tratamiento rehegua ndive, ha’eháicha coagulación ha oxidación Fenton, omoporãve haguã eficiencia tratamiento rehegua ha oñemboguejy haguã tratamiento repykue..

Tratamiento biológico ha’e pe método tradicional ha económico tratamiento de aguas residuales orgánicas rehegua.Ha katu, hetave umi y ky’a acelerante hasy oñepohano directamente umi método bioquímico convencional rupive, ko’ýte umi y ky’a oguerekóva juky yvate, nitrógeno amoníaco yvate ha umi orgánico tóxico yvate, ha’éva gueteri pe cuello de botella aplicación tecnología de tratamiento bioquímico rehegua.
