Ingano y'Ikoreshwa: Kwanduzwa kwa peteroli mu bisigazwa byo mu mazi
Ibisobanuro by'igicuruzwa:Udukoko twa mikorobe twakozwe hakoreshejwe ubwoko bw’udukoko twa bagiteri gakondo twakuwe mu duce twagizweho ingaruka n’amavuta yo mu Nyanja ya Pasifika. Udukoko twa mikorobe twinjizwa mu gikoresho gitwara ibintu hanyuma tugashyirwamo ikintu gitanga filime kugira ngo dukore iyi mikorobe. Udukoko twose twakorewe isuzuma ry’umutekano w’ibinyabuzima. Udukoko twa mikorobe twakoreshejwe neza mu kuvura ubwandu bwa peteroli mu myanda iri mu mazi yagizweho ingaruka n’amavuta.
Ikibazo cyo Gusaba: Umushinga w'Imyigaragambyo yo Gutunganya Imiterere y'Imyanda mu Bidukikije mu Mugezi Rusange
Umushinga wo kwerekana uburyo bwo gutunganya ibisigazwa by’amazi mu mazi yakuwemo wakozwe ku buso bwa kilometero kare 670.000 z’amazi yo mu nyanja yagizweho ingaruka n’isuka rya peteroli. Toni zirenga 360 z’imikorobe zashyizwe mu bikorwa, hakurikiraho gukurikirana nyuma yo kuvugurura. Igipimo cya peteroli mu biro bigenzura ibidukikije aho peteroli yamenetse cyaragabanutse cyane, aho igipimo cyo kwangirika cyageze kuri 90%.
（1）Agace ko gusana
Agace ko gutunganya imyanda gaherereye mu karere ko hagati mu mazi, ku bujyakuzimu bw'amazi bwa metero 28. Umuvuduko w'amazi yo hasi ni nk'amanota 2. Imyanda yo mu nyanja igizwe ahanini n'ibitaka by'ibumba. Imbuga zo mu mazi n'imiyoboro yo munsi y'inyanja biri hafi y'agace ko gutunganya imyanda.
（2）Guteza imbere udukoko twangiza peteroli twizewe kandi dukora neza cyane
Iterambere ry’udukoko duto dushyira imbere ubwoko bw’udukoko gakondo bufite ingaruka nke ku bidukikije. Udukoko gakondo twakuwe mu bisigazwa by’amazi mu turere two mu nyanja twagizweho ingaruka na peteroli dushobora gukumira byimazeyo kwinjira kw’udukoko tutari utwo mu nyanja no kugabanya impinduka ku miterere n’imikorere y’ahantu ho gusana.
Mu bizamini bya laboratwari, ubwoko bw’ibimera bwageze ku musaruro urenga 80% mu minsi 7 bwatoranijwe. Muri byo harimo Bacillus subtilis (umubare w’ibimera: Bs), Bacillus amyloliquefaciens (umubare w’ibimera: Ba), Bacillus safensis (umubare w’ibimera: Bb), Bacillus cereus (umubare w’ibimera: KF8), Acinetobacter calcoaceticus (umubare w’ibimera: T32), Pseudomonas putida (umubare w’ibimera: SP1), Acinetobacter sp. (umubare w’ibimera: HC8-3 na LKG-A), Oceanimonos baumannii (umubare w’ibimera: N6), na Bacillus pumilus (umubare w’ibimera: BPL-1), n’ibindi.
Hashingiwe ku buryo bwuzuye ku mikoranire ihuriweho hagati y’udukoko, hasuzumwe ubwoko butandukanye bw’udukoko kugira ngo hamenyekane uburyo bwo kwangirika kw’ibikomoka kuri peteroli bukoreshwa neza cyane. Hakozwe ibizamini byo mu rwego rwa laboratwari n’ibyo mu rwego rw’icyitegererezo kugira ngo hamenyekane uburyo urwego rw’udukoko twatoranijwe rukoresha peteroli rukora. Umutekano w’udukoko na wo wasuzumwe, harimo ibizamini by’uburozi mu mbeba n’ibizamini by’uburozi ku dukoko two mu mazi.
（3）Uburyo bwo gutwika imikorobe no gutunganya ibikoresho bya mikorobe
Uburyo bwo gushyushya mikorobe bwakoreweho ubushakashatsi, harimo imiterere y’uburyo bwo gushyushya, pH, ubushyuhe bwo gushyushya, umwuka n’uburyo bwo guhumeka mu cyuma gishyushya, ubwinshi n’imiterere y’uburyo bwo gushyushya mu gihe cyo kwimura hagati y’ibigega byo gushyushya, igihe cyo gushyushya, no kumenya ibyiciro by’ingenzi byo gushyushya. Hakozwe gahunda yo gushyushya ibyiciro bitatu ku buryo bwo gushyushya mikorobe.
Mu gace gakorerwamo ibikorwa byo gusana ibikomoka kuri peteroli gakorerwamo n'uyu mushinga, ubujyakuzimu bw'amazi bungana na metero 25-30. Iyo ibyo binyabuzima bigezwa mu mazi, ni bike cyane byabyo byagera mu mazi. Kugira ngo ubwoko bwinshi bw'ibikomoka kuri peteroli bushobora kwangiza ibikomoka kuri peteroli bugere mu mazi yo mu mazi, ibyo binyabuzima byasembuye bigomba gukomeza gutunganywa.
Uburyo bwo gutunganya burimo gufata imiti, kuyiteranya no kuyishyira mu kabati. Ubu buryo bushobora kugabanya neza ikwirakwira no gutakaza udukoko mu gihe cyo kuyishyira mu bikorwa, ndetse bugagabanya ingaruka z’udukoko twinjijwe mu mazi ku bice byo mu nyanja bitanduye.
(4) Gushyira mu bikorwa ibikoresho bya mikorobe
Ikiguzi cyo hejuru cy’ibikorwa byo mu mazi n’inyungu nke ku makosa bitera imbogamizi zikomeye ku bushakashatsi, ikoreshwa, n’iterambere ry’ikoranabuhanga ryo gutunganya ihumana ry’ibikomoka kuri peteroli yo mu mazi.
Mbere yo gushyiraho imiti igabanya ubukana bw’udukoko, hagomba gukorwa ibizamini birambuye byo kwigana, harimo no kwigana imibare n’igerageza ryo gushyira mu bikorwa ubushakashatsi ku rwego rwa laboratwari. Hashingiwe ku bisubizo byakozwe, ingano ikwiye yo gupakira n’agace gakwiye ko gushyirwamo bishobora kumenyekana, bityo bikarushaho kuba byiza umutekano n’ubushobozi bwo gukora ibikorwa byo mu nyanja.
Kugira ngo habeho ko ibikoresho bya mikorobe bishyirwa mu bikorwa neza kandi hagakorwa neza uburyo bwo gusana peteroli, igikorwa cyose—harimo ibikorwa byo gushyiraho ibikoresho, ingano y’ibikoresho bya mikorobe bikoreshwa, n’imikorere yo gutunganya ibikoresho—bishobora gukurikiranwa hakoreshejwe uburyo bwinshi, nko kureba kure mu kirere, kugenzura amashusho ku buso, no kugenzura munsi y’amazi. Izi ngamba zo gukurikirana zifasha kwemeza ko umushinga ushyirwa mu bikorwa neza, mu gihe zitanga imfashanyigisho z’ingirakamaro za tekiniki n’uburyo bwo gukoresha mu mishinga isa n’iyo mu gihe kizaza.
Ibikorwa byo mu mahanga
Ibikoresho byo kugenzura munsi y'amazi byakozwe ku giti cyabyo
(5) Isuzuma ry'Ingufu zo Gukosora Ibiyobyabwenge
Isuzuma ry’imikorere y’uburyo bwo kuvura indwara ryakozwe ryakozwe harimo isuzuma ry’ibanze rimwe mbere yo gukoresha imiti igabanya ubukana bw’udukoko ndetse n’isuzuma rikurikiraho rikurikira nyuma yo gukoresha imiti.
Ibipimo by'ingenzi byo kugenzura byari bikubiyemo ibipimo bisanzwe by'ubuziranenge bw'amazi (DO, fosifate, fosifate yose, azote idakomoka ku bimera, azote yose, nibindi); ubwinshi bwa peteroli mu mazi yo hejuru n'ibisigazwa; umubare wose wa bagiteri mu mazi n'ibisigazwa; ubwinshi bw'ubwoko bwa peteroli bwangiza mbere na nyuma yo kuvugururwa; hamwe n'impinduka mu bwinshi bw'udukoko n'ubwinshi mbere na nyuma yo kuvugururwa.
Nyuma yo gukosorwa, igipimo cya peteroli cyagabanutse kiva ku gipimo cy’ibanze cya 1.260 × 10⁻⁶ kigera kuri 210 × 10⁻⁶ mu bushakashatsi bwa mbere bwakozwe nyuma y’iminsi 70 bwo gushyirwa mu bikorwa. Mu bushakashatsi bwa kabiri bwakozwe nyuma y’iminsi 210 bwo gushyirwa mu bikorwa, igipimo cya peteroli cyagabanutse kigera kuri 155 × 10⁻⁶. Ku biro bigenzura hafi y’aho peteroli yamenetse, igipimo mpuzandengo cya peteroli cyari 56.34% nyuma y’iminsi 70 na 70.14% nyuma y’iminsi 210.
Imiterere y’umuryango w’ibinyabuzima bya macrobenthic na meiobenthic nta tandukaniro rigaragara byagaragaje mbere na nyuma yo guhindurwa. Nyuma yo guhindurwa, ibinyabuzima bya benthic, ubwinshi, n’ubwinshi byariyongereye gato, kandi imiryango y’ibinyabuzima ku bigo byasubiwemo yagaragaje ko bisa cyane n’ibiri mu turere two mu mazi tutanduye.
Ishyirwa mu bikorwa ry'uyu mushinga ryafashije gukemura ubwandu bwa peteroli mu bisigazwa byo mu mazi yo hagati mu karere ka [Location]. Byanakemuye ibibazo bitandukanye bijyanye no guhindura ibyavuye mu bushakashatsi bwa siyansi n'ikoranabuhanga mu bikorwa by'ubuhanga. Byongeye kandi, hari uburyo bushya bwasuzumwe mu gushushanya no gukoresha ibikoresho byo kwigana ibya laboratwari mu bikorwa byo mu nyanja.
Kugira ngo hashyigikirwe ishyirwa ry’imikorobe mu mazi yo mu nyanja no gukurikirana ibikorwa byayo nyuma yaho, hakozwe ibikoresho byo kugenzura hejuru no munsi y’amazi byigenga kandi byashyizwe mu bikorwa ku giti cyabyo. Mu gihe cy’ibikorwa byo mu nyanja, itsinda ry’umushinga ryanasuzumye imbogamizi zihari ku bikoresho byo kugenzura no gushakisha ibisubizo bishoboka byo kubikemura.
Nyuma yo gushyira mu bikorwa umushinga, ubwinshi bwa peteroli mu myanda hirya no hino mu gace kagenwe bwaragabanutse cyane, bijyana no kuvugurura ibidukikije mu rugero runaka. Uyu mushinga ugaragaza neza uburyo ibidukikije byo mu nyanja byasanwe, utanga inyungu zikomeye ku mibereho myiza no ku bidukikije.
