Njengamanje, i-COD evamile yamanzi angcolile idlula indinganiso ikakhulukazi ihlanganisa i-electroplating, ibhodi lesifunda, ukwenza iphepha, imithi, izindwangu, ukuphrinta nokudaya, amakhemikhali namanye amanzi angcolile, ngakho yiziphi izindlela zokwelashwa kwamanzi angcolile e-COD?Asihambe siyobona ndawonye.
Ukuhlukaniswa kwe-COD yamanzi angcolile.
Imithombo yokukhiqiza amanzi angcolile ihlukaniswe yaba: amanzi angcolile ezimbonini, amanzi angcolile ezolimo, kanye namanzi angcolile ezokwelapha.
Indle yasekhaya isho ingxube eyinkimbinkimbi yezinhlobo ezahlukahlukene zezinto eziphilayo ezakhiwe ngezinto ezingaphili neziphilayo, okuhlanganisa:
① Izinhlayiya eziqinile ezintantayo noma ezimisiwe
②Iziphazamisi ezifana nejeli
③Isixazululo esihlanzekile.
Izindlela zokwelashwa kwamanzi angcolile e-COD zihlanganisa:
Ukususwa kwe-COD ngendlela ye-coagulation: indlela ye-chemical coagulation ingasusa ngempumelelo izinto eziphilayo emanzini angcolile futhi yehlise i-COD ngezinga elikhulu.Inqubo ye-coagulation iyamukelwa, ngokungeza i-flocculant, kusetshenziswa i-adsorption kanye nebhuloho le-flocculant, ungqimba lukagesi oluphindwe kabili luyacindezelwa, ukuze i-colloid ne-suspended matter emanzini ingasebenzi, ingqubuzane, futhi ifinyezwe ibe yi-floc, bese kuba i-sedimentation noma umoya. flotation inqubo isetshenziselwa ukususa Izinhlayiya zihlukaniswa emanzini, ukuze kuzuzwe injongo yokuhlanza umzimba wamanzi.
Indlela yebhayoloji yokususa i-COD: Indlela yebhayoloji iyindlela yokwelapha amanzi angcolile ethembele kuma-enzyme e-microbial ukuze i-oxidize noma inciphise izinto eziphilayo ukuze kucekelwe phansi amabhondi angagcwele kanye nama-chromophore ukuze kufezwe injongo yokwelashwa.Eminyakeni yamuva nje, ama-microorganisms asetshenziswe kabanzi ekwelapheni ukukhuhla amanzi angcolile ngenxa yejubane lawo lokukhiqiza ngokushesha, ukuguquguquka okuqinile kanye nezindleko eziphansi.
Ukususwa kwe-Electrochemical COD: Ingqikithi yokwelashwa kwamanzi angcolile nge-electrochemical ukusebenzisa i-electrolysis ngokuqondile noma ngokungaqondile ukuze kukhishwe ukungcola emanzini, noma ukuguqula izinto ezinobuthi zibe izinto ezingenabo ubuthi nezinobuthi obuphansi.
Ukususwa kwe-COD nge-micro-electrolysis: Ubuchwepheshe be-Micro-electrolysis okwamanje buyindlela ekahle yokwelapha amanzi angcolile emvelo agxile kakhulu, aziwa nangokuthi i-electrolysis yangaphakathi.Ukusungulwa kusebenzisa izinto zokwenziwa kwe-micro-electrolysis ukugcwalisa amanzi angcolile ngaphansi kwesimo sokungabi bikho kukagesi, futhi kukhiqiza umehluko ongaba ngu-1.2V ngokwawo ukuze kusetshenziswe amanzi angcolile ngogesi ukuze kufezwe inhloso yokucekela phansi ukungcola kwemvelo.
Ukususwa kwe-COD ngendlela yokumuncwa: ikhabhoni ecushiwe, i-macroporous resin, i-bentonite nezinye izinto ezisebenzayo zokukhangisa zingasetshenziswa ukukhangisa nokwelapha i-organic matter kanye ne-chroma emanzini angcolile.Ingasetshenziswa njengokwelashwa kwangaphambili ukunciphisa i-COD okulula ukuyiphatha.
Indlela ye-oxidation yokususa i-COD: Eminyakeni yamuva, ukusetshenziswa kobuchwepheshe be-photocatalytic oxidation emkhakheni wokuhlanza amanzi angcolile kunamathuba amahle emakethe kanye nezinzuzo zezomnotho, kodwa zisenezinkinga eziningi ocwaningweni lwalo mkhakha, njengokuthola ama-catalysts asebenza kahle kakhulu. , ukuhlukaniswa nokubuyiselwa kwama-catalysts ukulinda.
