Nzira yekuyera sei salinity yetsvina?

Nzira yekuyera sei salinity yetsvina inyaya yekunetseka kukuru kune wese munhu. Chikamu chikuru chinoshandiswa kuyera salinity yemvura ndeye EC/w, inomiririra mafambisirwo emvura. Kusarudza conductivity yemvura inogona kukuudza kuti yakawanda sei munyu mumvura ikozvino.

TDS (inotaridzwa mumg/L kana ppm) inoreva huwandu hweiyoni iripo, kwete conductivity. Zvisinei, sezvambotaurwa, conductivity inowanzoshandiswa kuyera nhamba yeion iripo.

TDS metres inoyera conductivity uye shandura kukosha uku kuita kuverenga mumg/L kana ppm. Conductivity zvakare inzira isina kunanga yekuyera salinity. Pakuyera salinity, zvikamu zvinowanzoratidzwa mu ppt. Zvimwe zviridzwa zve conductivity zvinouya zvakagadzirirwa nesarudzo yekuyera salinity kana zvichidikanwa.

Kunyange zvazvo zvingave zvakaoma kunzwisisa, mvura yemunyu inoonekwa semutungamiri akanaka wemagetsi, izvo zvinoreva kuti paunenge uchiedza kuchengetedza kemikari yakarurama yemamiriro ekunze, kuverenga kwako kweEC / w kunofanira kunge kwakakwirira. Kana izvi zviverengero zvadzikira zvakanyanya, ingava nguva yekuchenesa mvura.

Nyaya inotevera inonyatso nyatsoongorora munyu uye kuti ungaiyera sei nemazvo.

Chii chinonzi munyu mumvura?

Munyu zvinoreva kuwanda kwemunyu wakanyungudika zvakanaka mumvura. Chikamu chekutanga chinoshandiswa kuyera salinity yemvura iEC/w, inomiririra mafambisirwo emagetsi emvura. Zvisinei, kuyera salinity yemvura ine conductivity sensor inokupa imwe chiyero chekuyera mu mS/cm, inova nhamba yemamilisiemens per centimeter yemvura.

Imwe millimita Siemens pacentimita yakaenzana ne1,000 micro Siemens pacentimita, uye chikwata iS/cm. Mushure mekutora chiyero ichi, chimwe-chiuru che micro-Siemens yakaenzana ne1000 EC, iyo magetsi emvura. Chiyero che1000 EC zvakare chakaenzana nezvikamu 640 pamiriyoni, inova chikamu chinoshandiswa kuona salinity mumvura yekushambira. Kuverengwa kwemunyu padziva remvura yemunyu kunofanirwa kuita 3,000 PPM, zvichireva kuti mamillisiemens pacentimita kuverenga kunofanirwa kuve 4.6 mS/cm.

Munyu unogadzirwa sei?

Kurapa kwemunyu kunogona kuitwa kuburikidza nenzira nhatu dzinosanganisira munyu wekutanga, munyu wechipiri, uye munyu wepamusoro.

Primary salinity ndiyo nzira yakajairika, inoitika kuburikidza nemaitiro echisikigo, sekuumbwa kwemunyu nekuda kwekunaya kwemvura kwenguva yakareba. Kana kunaya, mumwe munyu uri mumvura unobuda kubva pambiru yemvura kana muvhu. Mimwe munyu inogonawo kupinda mumvura yepasi kana muvhu. Mvura shoma inoyerera ichipinda munzizi nehova yozopedzisira yava mumakungwa nemumadziva.

Kana iri salinity yechipiri, rudzi urwu rwemunyu runoitika apo tafura yemvura inokwira, kazhinji semugumisiro wekubviswa kwezvinomera kubva kune imwe nzvimbo.

Munyu unogona kuwanikwa kuburikidza nemunyu wepamusoro, unoitika kana mvura ichishandiswa kurima gadheni uye zvirimwa pamusoro pematenderedzwa akawanda. Pese painodiridzwa mbesa, mvura shoma inopfava zvinoreva kuwedzera kwemunyu. Kana mvura ikashandiswazve nguva nenguva, munyu uri muchirimwa unogona kuva wakanyanya.

Chengetedzo kana uchishandisa iyoconductivity mita

1. Pakuyera mvura yakachena kana ultrapure mvura, kuitira kuti udzivise kukukurwa kwehuwandu hwakayerwa, zvinokurudzirwa kushandisa groove yakavharwa kuita kuyerwa kwekuyerera munzvimbo yakavharwa. Kana beaker ikashandiswa kuenzanisa uye kuyerwa, zvikanganiso zvakakura zvichaitika.

2. Sezvo muripo wekushisa unotora chiyero chekushisa chakagadziriswa che2%, kuyerwa kwe-ultra- uye yakakwirira-yakachena mvura inofanira kuitwa pasina muripo wekushisa zvakanyanya sezvinobvira, uye tafura inofanira kuongororwa mushure mekuyera.

3. Chigaro chepuragi che electrode chinofanira kuchengetedzwa zvachose kubva kuhunyoro, uye mita inofanira kuiswa munzvimbo yakaoma kudzivirira kubuda kana kuyerwa kukanganisa kwemamita nekuda kwekupfachuka kwemadonhwe emvura kana unyoro.

4. Chiyero chekuyeresa chikamu chakanyatsojeka, chisingagoni kuparadzaniswa, chimiro uye ukuru hwe electrode haigoni kuchinjwa, uye haigoni kucheneswa neasidhi yakasimba kana alkali, kuitira kuti irege kushandura electrode nguva dzose uye inokanganisa kururamisa kwekuyera kwechiridzwa.

5. Kuti uve nechokwadi chekuyera kwechiyero, electrode inofanira kushambidzwa kaviri nemvura yakasvibiswa (kana mvura yakasvibiswa) isingasviki 0.5uS / cm isati yashandiswa (platinum black electrode inofanira kunge yakanyoroveswa mumvura yakasvibiswa isati yashandiswa mushure mokunge yakaoma kwenguva yakati), Zvadaro simesa nemvura yakaedzwa yakaedzwa katatu musati wayera.
