1.Chidule cha Zamalonda:
Nayitrogeni yonse m'madzi makamaka imachokera ku zinthu zomwe zimawonongeka ndi nayitrogeni m'zimbudzi zapakhomo ndi tizilombo toyambitsa matenda, madzi otayira m'mafakitale monga ammonia yopangidwa ndi coking, ndi ngalande za m'minda. Pamene nayitrogeni yonse m'madzi ili yochuluka, imakhala yoopsa kwa nsomba ndipo imavulaza anthu m'njira zosiyanasiyana. Kuzindikira nayitrogeni yonse m'madzi kumathandiza kuwunika kuipitsa madzi ndi kudziyeretsa, kotero nayitrogeni yonse ndi chizindikiro chofunikira cha kuipitsa madzi.
Chowunikirachi chimagwira ntchito chokha komanso mosalekeza kwa nthawi yayitali popanda kuwonetsedwa malinga ndi malo omwe ali. Chimagwiritsidwa ntchito kwambiri m'madzi otayira omwe amatuluka kuchokera ku mafakitale, madzi otayira m'malo oyeretsera zinyalala, madzi otayira pamwamba pa malo oyeretsera zinyalala, ndi zina zotero. Malinga ndi zovuta za momwe malo amayeretsera, njira yoyenera yoyeretsera isanakwane ikhoza kusankhidwa kuti iwonetsetse kuti njira yoyesera ndi yodalirika, zotsatira za mayeso ndi zolondola, komanso kukwaniritsa zosowa za zochitika zosiyanasiyana.
2.Mfundo Yogulitsa:
Pambuyo posakaniza chitsanzo cha madzi ndi chophimba nkhope, nayitrogeni yonse mu mawonekedwe a ammonia yaulere kapena ammonium ion m'malo amchere komanso pamaso pa chowunikira, imagwira ntchito ndi potassium persulfate reagent kuti ipange mtundu wosiyanasiyana. Chowunikiracho chimazindikira kusintha kwa mtundu ndikusintha kusinthako kukhala mtengo wa ammonia nayitrogeni ndikutulutsa. Kuchuluka kwa mtundu wopangidwa ndi mtundu ndi kofanana ndi kuchuluka kwa ammonia nayitrogeni.
Njira iyi ndi yoyenera madzi otayira okhala ndi nayitrogeni yonse pakati pa 0-50mg/L. Ma calcium ndi magnesium ions ochulukirapo, chlorine yotsala kapena turbidity zitha kusokoneza muyeso.
3.Magawo aukadaulo:
| Ayi. | Dzina | Magawo aukadaulo |
| 1 | Malo ozungulira | Yoyenera madzi otayira okhala ndi nayitrogeni yonse yomwe ili pakati pa 0-50mg/L. |
| 2 | Njira Zoyesera | Kutsimikiza kwa spectrophotometric kwa potassium persulfate digestion |
| 3 | Mulingo woyezera | 0~50mg/L |
| 4 | Kuzindikira Malire otsika | 0.02 |
| 5 | Mawonekedwe | 0.01 |
| 6 | Kulondola | ± 10% kapena ± 0.2mg/L (tengani mtengo wokulirapo)） |
| 7 | Kubwerezabwereza | 5% kapena 0.2mg/L |
| 8 | Kuthamanga Kosalekeza | ±3mg/L |
| 9 | Kuthamanga kwa Span | ± 10% |
| 10 | Kuzungulira kwa muyeso | Nthawi yocheperako yoyesera ndi mphindi 20. Nthawi yoyerekeza mtundu wa chromogenic imatha kusinthidwa mu mphindi 5-120 kutengera malo omwe ali. |
| 11 | Nthawi yoperekera zitsanzo | Nthawi yosinthira (yosinthika), ola limodzi kapena njira yoyezera zinthu ingathe kukhazikitsidwa. |
| 12 | Kuzungulira kwa calibration | Kuyesa kokha (kusinthidwa masiku 1-99), malinga ndi zitsanzo zenizeni zamadzi, kuyesa kokha kumatha kukhazikitsidwa. |
| 13 | Nthawi yokonza | Nthawi yosamalira ndi yoposa mwezi umodzi, pafupifupi mphindi 30 nthawi iliyonse. |
| 14 | Kugwira ntchito kwa makina a anthu | Kukhudza chophimba chowonetsera ndi malangizo olowera. |
| 15 | Chitetezo chodziyang'anira | Kugwira ntchito kumadziyesa wekha, kusakhala bwino kapena kulephera kwa magetsi sikutaya deta. Kumachotsa zokha zinthu zotsalira zomwe zimagwirira ntchito ndikuyambiranso ntchito pambuyo pobwezeretsa kapena kulephera kwa magetsi. |
| 16 | Kusunga deta | Kusunga deta kosachepera theka la chaka |
| 17 | Mawonekedwe olowera | Sinthani kuchuluka |
| 18 | mawonekedwe otulutsa | Zotulutsa ziwiri za digito za RS232, Chotulutsa chimodzi cha analog cha 4-20mA |
| 19 | Zikhalidwe Zogwirira Ntchito | Kugwira ntchito m'nyumba; kutentha 5-28℃; chinyezi chocheperako ≤90% (popanda kuzizira, palibe mame) |
| 20 | Kupereka Mphamvu ndi Kugwiritsa Ntchito | AC230±10%V, 50~60Hz, 5A |
| 21 | Miyeso | 355×400×600(mm) |
