Inqubo yokwelashwa kwamanzi angcolile aqukethe i-cyanide kanye namanzi angcolile e-sodium cyanide

Emkhakheni wokuvikelwa kwemvelo, ukwelashwa kwe i-cyanide - equkethe amanzi angcolile kanye I-sodium cyanide amanzi angcolile sekuyisikhathi eside eyisihloko esibalulekile. Ngokuthuthuka okusheshayo kokukhiqizwa kwezimboni, ikakhulukazi ezimbonini ezifana ne-electroplating, i-metallurgy, namakhemikhali, ukuchithwa kwe-cyanide - aqukethe amanzi angcolile bekulokhu kwanda unyaka nonyaka, okubeka usongo olukhulu emvelweni. Ngakho-ke, ukuhlolwa kobuchwepheshe bokwelapha obusebenzayo, obuyongayo, kanye nobungane nemvelo be-cyanide - equkethe amanzi angcolile kubaluleke kakhulu.

Izici Nezingozi Ze-Cyanide - Iqukethe Amanzi Angcolile

I-Cyanide - equkethe amanzi angcolile ngokuvamile iqukethe izinto ze-cyanide ezigxilile, ezitholakala emanzini ngamafomu amahhala noma ayinkimbinkimbi. Phakathi kwazo, i-metal - cyanide complexes, njenge-copper - cyanide complexes kanye ne-zinc - cyanide complexes, izinzile futhi kunzima ukuyisusa ngokusebenzisa izindlela zokwelashwa ezivamile. Ngaphezu kwalokho, amanzi angcolile angase futhi aqukathe amanye ama-ion ensimbi, izinto eziphilayo, ama-acids, ama-alkali, nezinye izinto, ezinokwakheka okuyinkimbinkimbi, okwandisa ubunzima bokwelashwa. Ukukhishwa kwe-cyanide - equkethe amanzi angcolile akugcini nje ngokungcolisa imizimba yamanzi kodwa futhi inqwabelana ngochungechunge lokudla, kube usongo lwesikhathi eside endaweni ezungezile nempilo yabantu.

Ubuchwepheshe Bokwelapha be-Cyanide - Equkethe Amanzi Angcolile

Uma kubhekwa izici ze-cyanide - eziqukethe amanzi angcolile, ubuchwepheshe bokwelapha obusetshenziswa kakhulu njengamanje buhlanganisa izindlela zokwelashwa kwe-oxidation, izindlela zokwelapha i-electrolytic, izindlela zokushintshanisa i-ion, izindlela zokwelapha zebhayoloji, kanye nokusetshenziswa okuhlangene kobuchwepheshe obuningi.

Izindlela Zokwelapha I-Oxidation

Indlela ye-Alkaline Chlorination

Ngaphansi kwezimo ze-alkaline (ngokuvamile enenani le-pH eliphakathi kuka-10 no-11), ama-oxidants afana ne-chlorine noma i-sodium hypochlorite ayengezwa ukuze axube izinto ze-cyanide zibe yi-nitrogen engeyona enobuthi kanye I-Carbon i-dioxide. Le ndlela kulula ukuyisebenzisa, inemiphumela yokwelapha eqinile, futhi imithi itholakala kalula futhi ayibizi kakhulu. Kodwa-ke, ingabangela ukungcola kwesibili futhi inomphumela othile wokugqwala emishinini.

I-Hydrogen Peroxide Oxidation Indlela

Ngaphansi kwezimo ezine-acidic noma ze-alkaline, i-hydrogen peroxide isetshenziswa njenge-oxidant ukuze i-oxidize izinto ze-cyanide zibe i-nitrogen namanzi. Ifaneleka kakhulu ukwelapha amanzi angcolile ngezinto ezisezingeni eliphezulu ze-cyanide, kodwa izindleko zokwelashwa ziphezulu, futhi izimo zokusabela zidinga ukulawulwa ngokuqinile.

Indlela Ye-Ozone Oxidation

Ngokusebenzisa impahla eqinile ye-oxidizing ye-ozone, izinto ze-cyanide zikhishwa zibe yizinto ezingezona ezinobuthi. Ukusebenza kahle kokwelashwa kuphezulu futhi akukho ukungcoliswa kwesibili, kodwa utshalomali lwemishini kanye nezindleko zokusebenza ziphezulu.

Indlela ye-Fenton Oxidation

I-Fenton reagent eyakhiwe nge-hydrogen peroxide kanye nosawoti wensimbi isetshenziselwa ukukhishwa kwamakhemikhali ukuze kucekelwe phansi izinto ze-cyanide.

I-Electrolytic Treatment Method

I-electrochemical oxidation reaction isetshenziselwa ukubhubhisa izinto ze-cyanide emanzini angcolile. Ngaphansi kwezimo ezithile, ama-ion e-cyanide emanzini angcolile afakwa i-carbon dioxide, i-nitrogen, ne-ammonia. Ilungele ukwelapha amanzi angcolile ngama-ion e-cyanide aphezulu, kodwa idla amandla kagesi futhi ingase ikhiqize igesi enobuthi ye-cyanogen chloride.

I-Ion - Indlela Yokushintshanisa

I-anion eqinile - isisekelo - ama-resin okushintshaniswa asetshenziselwa ukushintshanisa ne-cyanide ions esixazululweni, ukufeza ukususwa kwe-cyanide ions. Ilungele ukwelapha i-cyanide - equkethe amanzi angcolile anezinga eliphakathi nendawo neliphansi, inokwelashwa okuphezulu okusebenzayo, futhi ingabuyisa ama-ion ensimbi abalulekile, kodwa izindleko zokwelashwa ziphezulu uma kuqhathaniswa.

Indlela Yokwelapha Ngebhayoloji

Ngokucekelwa phansi kwama-microorganisms, izinto ze-cyanide ziguqulwa zibe izinto ezingezona ezinobuthi noma ezinobuthi obuphansi. Ihambisana nemvelo futhi iyasimeme, kodwa idinga izimo zemvelo ezifanele (ezifana nezinga lokushisa, inani le-pH, njll.) kanye nesikhathi eside sokwelashwa. Izindlela zokwelashwa ezijwayelekile zebhayoloji zifaka indlela yodaka ecushiwe kanye nendlela ye-biofilm.

Izinqubo Ezihlanganisiwe

Uma kubhekwa inkimbinkimbi ye-cyanide - equkethe amanzi angcolile, ukusetshenziswa okuhlangene kobuchwepheshe obuningi kuvame ukwamukelwa. Isibonelo, "indlela ye-alkaline chlorination + ion - exchange method", "electrolytic treatment method + ion - exchange method", "hydrogen peroxide oxidation method + biological treatment method", njll. Ngezinqubo ezihlangene, ukujula kokwelashwa kwamanzi angcolile kungafinyelelwa, futhi izinga lokungcola lingathuthukiswa.
