Iron Sulfide mumazi: Ubuyobozi BwuzuyeGusobanukirwa ahari ningaruka za icyuma cya sulfide mu mazi ni ngombwa mu nganda zitandukanye no gukurikirana ibidukikije. Iyi ngingo iracengera muburyo, imiterere, gutahura, no gukosora icyuma cya sulfide mu mazi, gutanga ubushishozi bufatika kubanyamwuga n'abashakashatsi. Tuzareba ingaruka zabyo ku bwiza bw’amazi, inzira z’inganda, n’ubuzima bw’ibidukikije. Wige uburyo bwo kumenya, gucunga, no kugabanya ingaruka zuru ruganda rwiganje.

Iron Sulfide mumazi: Igitabo Cyuzuye

Sulfide y'icyuma mumazi ni ikibazo gikunze kwibasira inzego zitandukanye, kuva gutunganya amazi munganda kugeza kurengera ibidukikije. Uru ruganda, rukunze kuboneka nka pyrite (FeS₂) cyangwa ubundi buryo, burashobora guhindura cyane ubwiza bwamazi nibikorwa byinganda. Gusobanukirwa imyitwarire n'ingaruka zayo nibyingenzi mugucunga neza no kugabanya. Aka gatabo gatanga incamake yuzuye ya icyuma cya sulfide mu mazi, ikubiyemo imiterere, imitungo, uburyo bwo gutahura, hamwe ningamba zo gukosora.

Imiterere ya Sulfide y'icyuma mumazi

Inkomoko ya geologiya

Sulfide y'icyuma cyane cyane bituruka kumasoko ya geologiya. Pyrite, imyunyu ngugu ya sulfide isanzwe, ikwirakwizwa cyane mu bitare no mu butaka. Ikirere n'isuri by'ibi bice birekura ion na sulfide ion mu mazi, bigatuma habaho gushonga sulfide cyangwa imvura yacyo nkibice bikomeye. Imiterere yihariye hamwe nibitekerezo biterwa nibintu nka pH, ubushobozi bwa redox, no kuba hari izindi ion. Gusobanukirwa n'amasoko ya geologiya ni ngombwa muguhishurira ubushobozi bwa sulfide kwanduza muri sisitemu y'amazi yihariye. Kurugero, uduce dufite ubunini bwinshi bwamabuye ya pyrite birashoboka cyane sulfide kwanduza amazi yo mu butaka.

Inzira y'ibinyabuzima

Inzira y'ibinyabuzima nayo igira uruhare sulfide kwibumbira mu mazi. Bagiteri zigabanya sulfate (SRB) ni mikorobe ikoresha sulfate nk'iyakirwa na electron mu bihe bya anaerobic, itanga ioni sulfide nk'umusaruro. Izi ion sulfide noneho zifata ibyuma byashongeshejwe, bigatuma habaho sulfide ferrous (FeS) cyangwa ibindi byuma bya sulfide. Igikorwa cya SRB giterwa nibintu nkibintu kama kiboneka, ubushyuhe, na pH. Mubihe byinshi, inzira yibinyabuzima igira uruhare runini mubitekerezo hamwe nuburyo bwa sulfide muri sisitemu yo mumazi, cyane cyane mubidukikije bya anaerobic nkibimera cyangwa amazi adahagaze.

Ibyiza n'ingaruka za Sulfide y'icyuma mumazi

Sulfide y'icyuma mumazi yerekana ibintu bitandukanye bigira ingaruka zikomeye kumiterere yamazi nibikorwa byinganda. Ubushobozi bwibintu bitandukanye bya sulfide ya sulfide biratandukanye cyane bitewe na pH na redox. Kurugero, sulfide ferrous (FeS) ntigishobora gukemuka mugihe kidafite aho kibogamiye cyangwa alkaline nkeya, mugihe uburyo bukomeye bushobora kwerekana imiterere itandukanye. Kubaho kwa sulfide mumazi arashobora gukurura ibibazo byinshi:

Ibibazo byubuziranenge bwamazi

Urwego rwo hejuru rwa sulfide irashobora gutanga uburyohe budashimishije numunuko kumazi, bigatuma bidakwiriye kunywa no gukoresha ibindi murugo. Kubaho hydrogène sulfide (H.₂S), gaze ya gaze ya fer sulfide yangirika, igira uruhare mumpumuro mbi. Byongeye kandi, sulfide ya fer irashobora kwanduza ibikoresho byo kumashanyarazi hamwe nigitambara, bigatera ibibazo byuburanga. Ibi nibibazo byumwihariko mubikorwa byinganda bisaba amazi meza.

Ingaruka mu nganda

Mu nganda, sulfide irashobora gutera ibibazo bikomeye. Irashobora kwangiza imiyoboro, reaction, nibindi bikoresho, biganisha ku kugabanya imikorere no kongera amafaranga yo kubungabunga. Sulfide y'icyuma Irashobora kandi guhagarika reaction yangirika, yangiza ibyuma. Ibikorwa byinshi byinganda bisaba amazi hamwe nubushyuhe buke cyane bwashonze sulfide, gusaba uburyo bukomeye bwo gutunganya amazi.

Kumenya no Gukosora Sulfide Yuma mumazi

Kumenya neza no gukosora neza nibyingenzi mugucunga sulfide mu mazi. Uburyo butandukanye bukoreshwa mugushakisha no kuvanaho uru ruganda mumazi.

Uburyo bwo Kumenya

Uburyo butandukanye bwo gusesengura bukoreshwa kugirango tumenye icyuma cya sulfide mu mazi. Harimo uburyo bwa colimetricique, atomic absorption spekitroscopi (AAS), hamwe na plasma mass mass spectrometrie (ICP-MS), buri kimwe gitanga urwego rutandukanye rwimyumvire kandi yihariye. Guhitamo uburyo biterwa nurwego rusabwa rwukuri hamwe nibikoresho bihari. Kumenya kwizewe kandi neza nibyingenzi muburyo bwiza bwo kuyobora. Gukurikirana buri gihe ni ngombwa mu kumenya no gucunga ubushobozi sulfide ibibazo.

Ingamba zo gukemura

Ingamba nyinshi zo gukosora ziraboneka mugukuraho cyangwa kugabanya sulfide kuva mu mazi. Mubisanzwe birimo okiside, imvura, hamwe nubuhanga bwo kuyungurura. Oxidation inzira ihindura iseswa sulfide muburyo buke bwo gushonga, kuborohereza kubikuramo binyuze mumvura cyangwa kuyungurura. Uburyo bwihariye burimo guhinduranya, okiside yimiti ukoresheje okiside nka chlorine cyangwa potasiyumu permanganate, hamwe na okiside yibinyabuzima ukoresheje mikorobe yihariye. Ubuhanga bwo kuyungurura, nko kuyungurura umucanga, gukora karubone ya adsorption, hamwe no kuyungurura membrane, birashobora kandi kuvanaho amazi ya sulfide yaguye mumazi. Guhitamo ingamba zifatika zo gukosora biterwa nibiranga amazi, ubwinshi bwa sulfide, hamwe nubuziranenge bwamazi yifuzwa.

Kubindi bisobanuro kubisubizo byo gutunganya amazi, tekereza gushakisha uburyo bwiza butangwa namasosiyete nka Imbere muri Mongoliya Xinxin Silicon Inganda Co, Ltd.. Bafite ubuhanga bwo gutanga ikoranabuhanga rigezweho ryo kweza amazi.

Aka gatabo gatanga incamake yuzuye ya icyuma cya sulfide mu mazi. Wibuke guhora ugisha inama abanyamwuga babishoboye kugirango basuzume neza ningamba zifatika zo gukosora zijyanye nibihe byihariye. Ibisobanuro byatanzwe hano bigomba kurebwa kubikorwa byuburezi gusa kandi ntabwo bigize inama zumwuga.
