Ubushakashatsi bwa siyansi bwerekana ko azote nyinshi yinjira mu mazi bizatera eutrophasi y’umubiri w’amazi kandi bikagira ingaruka ku bwiza bw’amazi y’amazi ku rugero runaka. Ibisabwa mu micungire y’ibidukikije mu Bushinwa byiyongera buri mwaka, kubera ko igihugu cyanjye gisohora imyanda y’imyanda A yo mu rwego rwa A ibuza cyane ibirimo N, kandi n’imyanda y’imyanda yo mu cyaro nayo isabwa na azote. Uyu munsi, Kurengera Ibidukikije bizatangiza muri make tekinoroji yongerewe ubumenyi kuri wewe.
Kunoza ikoranabuhanga rya denitrification bivuga kunoza ubushobozi bwo kwangirika kwibintu birimo azote, kongera igipimo cyo kwangirika no kuzamura ubwiza bw’imyanda hifashishijwe imiti ya mikorobe, kongeramo uburyo bw’umubiri n’imiti no kunoza inzira mugihe cyo gutunganya umwanda. Kwangiza ibinyabuzima mu gutunganya imyanda byakuruye abantu, ariko uburyo bwo gukora neza uburyo bwo kuvura umwanda biracyari ikibazo kitoroshye mu gutunganya imyanda.
Bio-yongerewe ubumenyi bwa denitrification ikoreshwa cyane mugutunganya imyanda yo mucyaro. Mugushyiramo bagiteri zihariye, intungamubiri cyangwa insimburangingo igereranya no kuvura ibinyabuzima, biomass mu kuvura irashobora kwiyongera, ubushobozi bwo kwangirika kwumubiri ku myanda ihumanya irashobora gutezwa imbere, kandi igipimo cyo kwangirika gishobora kunozwa, bityo kikaba gishobora kugera ku ntego y’imyanda. kwivuza. Ikoranabuhanga rifite ibiranga igiciro gito, imikorere myinshi n’umwanda muke. Usibye ibimera gakondo, mikorobe zagize uruhare rugaragara mu kuzenguruka kwa azote muri kamere zirimo na bagiteri ya anammox, denitrifiers yo mu kirere, hamwe na bagiteri ikuraho fosifore hamwe na mikorobe ikomeye ya azote-metabolizing.
Mu rwego rwo kwemeza ko irekurwa ry’ibintu bya azote muri sisitemu y’imyanda bigera ku gipimo ngenderwaho, ingamba nko kongera igipimo cy’imiterere y’imiterere, kongera igihe cyo gufata hydraulic, kongera igipimo cy’imyunyu ngugu, kugabanya umutwaro w’amazi, guhindura ubushyuhe bwa reaction , cyangwa kongera umubyimba wuzuza birashobora gukoreshwa mumushinga. Nyamara, iki gikorwa kizongera amafaranga yo kubaka no gukoresha ibikorwa byo gutunganya imyanda, bikavamo ingaruka zikomeye mu bukungu. Nubwo uburyo bwa fiziki-chimique bwongereye tekinoroji ya denitrification yatejwe imbere hakiri kare, hariho ibibazo nkigiciro cyinshi, byoroshye kubyara indwara zanduza, hamwe n’umwanda wa kabiri. Ibikorwa bishya byongerewe imbaraga muburyo bwo kubitandukanya harimo inzira ngufi ya nitrification-denitrification, inzira ya heterooxygenation-aerobic denitrification, aerobic granular sludge, intera ngufi ya nitrification-anammox, nibindi.
Ibyo aribyo byose kuri iki kibazo, kubindi byinshi, nyamuneka witondere kugabana kwa Liding mu nomero itaha. Kurengera Ibidukikije byiyemeje gushushanya, gukora ubushakashatsi no guteza imbere, gukora no gukoresha ibikoresho byo gutunganya imyanda yegerejwe abaturage mu karere k’ibidukikije mu myaka icumi. Kwishingikiriza kumurongo wumwuga usanzwe kandi wuburyo bwikora, Ibicuruzwa bitwara bifite ibyiza bigaragara mubwiza no mubikorwa. Ibikoresho byifashishwa mu gutunganya imyanda yo mu rugo birashobora gukoreshwa neza mu cyaro gitatanye. Niba ukeneye ibisubizo byibicuruzwa ninama za tekiniki, ikaze kubaza.
