Impamvu Sensorer za Nitrate ISE zo mu gihe nyacyo zisimbura ingero za buri gihembwe mu turere turindwa amazi yo munsi y'ubutaka mu Burayi

Dore uko ibintu bigenda buri gihembwe mu gupima nitrate yo mu mazi yo mu butaka. Umutekinisiye wo mu kigo cy’amazi agera ku iriba rigenzura ku ya 15 Werurwe, amanura umuntu ufata icyitegererezo, atora icyitegererezo cya mililitiro 500, maze acyohereza muri laboratwari yemewe. Raporo ya laboratwari igera ku ya 22 Werurwe. Igipimo cya nitrate kuri iryo riba, kuri uwo munsi umwe muri Werurwe, cyari 48 mg/L - 2 mg/L munsi y’umurongo ntarengwa w’amabwiriza ya EU Nitrates wa 50 mg/L. Raporo ya buri gihembwe iratangwa. Aho iriba rikomeje gukora.

Icyo raporo itagaragaza: imvura nyinshi yabaye ku ya 19 Werurwe yatumye azote iva mu murima w’ibigori wari uherutse gufumbirwa ijya mu mwobo muto. Ku ya 24 Werurwe, igipimo cya nitrate kuri iryo riba cyo kugenzura cyari 71 mg/L. Icyitegererezo gikurikiraho giteganijwe ku ya 15 Kamena. Mu minsi 83, amazi yo kunywa afite nitrate irenze urugero rwemewe n’amategeko yakuwemo, avurwa, kandi akwirakwizwa mu ngo. Nta muntu wari ubizi. Gahunda yo gufata ingero za buri gihembwe, ikurikije neza ibisabwa n’amategeko mu kugenzura, yafashe amakuru amwe yagaragaye hagati y’ingendo ebyiri.

Sensor: Icyo "Electrode itoranya ikoresheje ion" mu by'ukuri isobanura ku mazi yo munsi y'ubutaka

Imashini ipima nitrate ya ISE ntabwo ipima nitrate mu buryo bw'ijisho. Ntabwo ikoresha uburyo bwo kwinjiza UV nk'uko imashini ipima COD yo hejuru y'amazi ibikora. Ikoresha membrane ya polymer irimo ionophore - molekile ihuza iyoni za nitrate mu buryo bwihariye - kugira ngo ikore voltage potential ijyanye n'ibikorwa bya nitrate mu mazi ayikikije. Iyo voltage, ipimwa ukoresheje electrode reference kandi igasubizwa ubushyuhe, ihinduka igipimo cya concentration muri mg/L binyuze muri equation ya Nernst.

Guhitamo ni ingenzi kuko amazi yo munsi y’ubutaka atari igisubizo cya nitrate gusa. Irimo chloride, bicarbonate, sulfate, na karubone y’umwimerere ishongeshejwe, byose bishobora kubangamira gupima niba membrane idatoranyije bihagije. Uruhu rw’icyuma cya Honde sensor rufite coefficient ya nitrate ya hafi 0.001 ugereranije na chloride - bivuze ko rusubiza inshuro zigera ku 1.000 cyane kuri nitrate kuruta chloride ku rugero rungana. Mu mazi yo munsi y’ubutaka yo mu Buholandi, aho chloride mu mazi y’umucanga ikunze kuba hagati ya 20 na 80 mg/L, ibi bivuze ko chloride ibangamira 0.1 mg/L ya nitrate igaragara - ntabwo ikoreshwa cyane ugereranije n’urwego rugenwa na 50 mg/L.

Umusaruro wa digitale wa RS485 Modbus-RTU ukuraho kwangirika kw'ibimenyetso bya analog kuri metero 30 kugeza ku 100 z'umugozi uri hagati ya sensor iri munsi y'amazi y'iriba n'ikimenyetso cy'amakuru. Mu muyoboro wa analog wa 4-20mA unyura kuri metero 80 z'umugozi unyuze mu gisenge cy'iriba ritose, ikimenyetso gishobora gutemberaho 2-3% bitewe n'ingaruka z'umuyoboro wo hasi n'ubwinjirire bw'ubushuhe mu gasanduku k'amahuriro. RS485 y'ikoranabuhanga iratandukanye - ipima itandukaniro ry'amashanyarazi hagati y'insinga ebyiri z'amakuru, n'urusaku rusanzwe ruhagarika. Ishusho ku muyoboro isa n'ishusho ku kimenyetso.

Ubushyuhe bwikora bwubatswe mu mutwe w’imashini zipima ubushyuhe. Ubushyuhe bw’amazi yo munsi y’ubutaka mu mazi maremare yo mu Buholandi burahinduka bitewe n’ibihe kuva kuri dogere selisiyusi 8 muri Werurwe kugeza kuri dogere selisiyusi 14 muri Nzeri. Igereranya rya Nernst rikubiyemo imiterere y’ubushyuhe ishingiye ku bushyuhe itanga ikosa rya 2% kuri dogere selisiyusi iyo idasubijwe. Thermistor ihuriweho ikosora ibi mu gihe nyacyo.

Kuki Ubuholandi bwaba, kuki ubu

Ubuholandi bugendera ku mabwiriza ya Nitrates yo kwanga ifumbire y’amatungo - uruhushya rwihariye rwo gukoresha ifumbire y’amatungo menshi kuri hegitari ugereranyije n’ingano isanzwe ya azote kuri hegitari 170 ku mwaka - bitewe n’ubuhinzi bw’ubwatsi butanga umusaruro mwinshi mu gihugu. Iyi nyunganizi yongeye kuvugururwa, hanyuma irakomezwa, maze ibaruwa ya Komisiyo y’Ubumwe bw’u Burayi yo mu Ukuboza 2025 yandikiye Minisitiri w’Ubuhinzi w’u Buholandi, Femke Wiersma, igaragaza neza ko hakenewe "gukurikirana neza" nitrate yo mu mazi mu turere tw’umucanga. Isuzuma rya Komisiyo ryo muri Nyakanga 2026 ryemeje ko aya mabwiriza "akomeje kuba ngombwa, afite akamaro kandi afite akamaro" kugira ngo arinde amazi y’Umuryango w’Ubumwe bw’u Burayi.

Muri Mata 2026, hashyizweho uburyo bwo gupima imiterere y’amazi yo mu mazi ya Honde RS485 nitrate ISE, mu mwobo 25 ugenzura ibidukikije mu turere turinzwe amazi yo munsi y’ubutaka twa Groningen na Drenthe, dukorerwamo n’ikigo cy’amazi yo kunywa cya Vitens.

Uburyo Urugaga Rukora mu Bigo 25 Bishinzwe Gukurikirana

Amariba 25 afite uburebure bwa metero 15 kugeza kuri 45, yose ari mu mazi y’umucanga ya Pleistocene afite ubushobozi bwo gutwara amazi menshi - bivuze ko akira vuba cyane ku mazi akomoka kuri nitrati kandi agakira vuba iyo isoko ya azote ikuweho. Gusubiza vuba bikora mu buryo bwombi: ikigero cy’amazi kirimo kwiyongera kuva kuri 30 kugeza kuri 70 mg/L mu minsi itatu nyuma y’imvura nyinshi, kandi gishobora kugabanuka kikagera kuri 35 mg/L mu cyumweru nyuma y’aho umwuka unyuze. Ingero ya buri gihembwe ishobora kubura ubwiyongere n’ubwiyongere, ikagaragaza ko ari 42 mg/L nk’aho nta cyabaye.

Buri sensor ya nitrate ya Honde ishyirwa ku gice cyometseho cy'icyobo cyo kugenzura, ishyizwe ku mugozi w'icyuma kitagira umugese ku bujyakuzimu aho amazi yo munsi y'ubutaka yinjira mu gisenge cy'icyobo. Insinga ya RS485 igera ku mugozi ushyira amakuru mu gikoresho cyo kugenzura. Ku mariba 18 muri 25, uyu mugozi uhuza na module ya 4G yohereza ibipimo bya nitrate mu minota 15 muri MQTT Json kuri platforme ya Vitens yo hagati y'amazi meza. Ku mariba 7 asigaye - aherereye mu bubiko bw'ibidukikije bwa kure aho itumanaho rya telefoni ritaboneka - module ni LoRaWAN, yohereza amakuru ku irembo riri kuri sitasiyo ya pompe iri hafi, mu birometero 8 kugeza kuri 14.

Ku mutwe w'amazi, icyuma gipima amakuru gifite ecran kigaragaza ingano ya nitrate iriho ubu, icyerekezo cy'amasaha 24, n'amateka y'iminsi 30. Mu gihe cyo kugenzura imiterere y'amazi buri kwezi, umutekinisiye w'umurima akoresha Handmeter kugira ngo arebe neza icyuma gipima amazi cyashyizweho n'ingero yafashwe na laboratwari yakusanyijwe icyarimwe iva mu mwobo umwe. Iyo icyuma gipima amazi cyarenze ± 2 mg/L, gisimbuzwa aho kiri mu mwanya wacyo mu minota iri munsi ya 20 hanyuma kigasubirwamo muri laboratwari nkuru ya Vitens.

Seriveri ya Cloud na porogaramu bihuza amadirishya yose 25 mu dashibodi imwe. Umuyobozi w'ibikorwa ashobora kubona amakuru y'igihe nyacyo n'amateka y'amadirishya yose. Ariko dashibodi si bwo buryo bw'ibanze bwo kurinda umutekano.

Sisitemu yo kugarura amazi mu kirere ni. Buri riba rifite ingano ebyiri zagenwe. Ingano ya mbere, kuri 40 mg/L, itangira gutanga imenyesha ry’ubuziranenge bw’amazi hakiri kare - ikimenyetso cy’uko iriba riri hafi kugera ku rugero rwemewe na leta rwa 50 mg/L kandi rishobora gusaba ko habaho ihinduka ry’uruvange ku ruganda rutunganya amazi. Ingano ya kabiri, kuri 50 mg/L, itera ingano ifatika ishobora kuzimya ipompo y’iriba cyangwa igakoresha irindi riba rikura amazi, igahindura amazi mbere y’uko amazi yanduye agera aho akoreshwa.

Ibisubizo ku murima: Uduce turinda amazi yo munsi y'ubutaka twa Groningen-Drenthe, Mata–Nyakanga 2026

Ibisubizo by'ibikorwa nyuma y'iminsi 100:

• Utumashini dupima ibintu dukomeza twabonye ko hari ubushyuhe 31 bwa nitrate buri hejuru ya 50 mg/L bwaguye neza mu gihembwe hagati y’itariki yo gufata ingero. Ibi bikorwa 31, bingana n’amasaha agera ku 1.800 yo gupimwa nitrate ku buryo burenze urugero, ntibyari kugaragara kuri gahunda yo gufata ingero buri gihembwe.
• Ku byuma 6, sisitemu yo gusubiza alarm yatumye pompe ifunga byihuse ubwo nitrate yarengaga 50 mg/L. Kuri buri byuma 6, igipimo cya nitrate cyari cyaragabanutse kiri munsi ya 40 mg/L mu gihe icyitegererezo cya buri gihembwe cyari kuba cyarafashwe - bivuze ko urugendo rwari kuba rudakurikije amabwiriza yabanje yo kugenzura.
• Uburinganire bwa sensor ya ISE, bwemejwe hakurikijwe isesengura rya laboratwari ry’ingero zafashwe buri kwezi, bwageze kuri ± 1.8 mg/L kuri sensor zose 25 mu gihe cy’iminsi 100. Sensor imwe yavuye hanze y’ubushobozi bwa ± 2 mg/L mu kwezi kwa kabiri - drift yabonetse hakoreshejwe igenzura rya Handmeter rya buri kwezi maze sensor irasimburwa.
• Itsinda rya Vitens rishinzwe ubuziranenge bw'amazi ryakoresheje amakuru y'umuburo wa mbere yavuye ku rugero rwa 40 mg/L kugira ngo rihindure mbere y'uko rivanga ibikoresho ku nganda eshatu zitunganya amazi, birinda ko hashobora kurenza urugero rw'amazi 12 mbere yuko agera ku rugero rwa 50 mg/L.
• Hashingiwe ku makuru y’igerageza, Vitens yasabye ko habaho kongera igenzura rihoraho rya nitrate kugeza ku bindi byobo 60 byo kugenzura mu turere twayo twa Gelderland na Overijssel mu 2027.
