Yakaturikwa yakaoma, sekureva kwazvinoreva, zvinhu zvidiki zvinoyangarara zvakasununguka mumvura, kazhinji pakati pe 0.1 microns uye 100 microns muhukuru. Zvinosanganisira asi zvisingagumiri kune silt, ivhu, algae, microorganisms, high molecular organic matter, nezvimwewo, zvichiita mufananidzo wakaoma wepasi pemvura microcosm. Zvimedu zvakaturikwa mumvura pamusoro pemvura uye pasi pevhu kazhinji zvinobva mumaitiro echisikigo, senge silt inotakurwa nenzizi uye plankton mumadziva; nepo zvimedu zvakaturikwa mutsvina yemuguta uye mvura yetsvina yemumaindasitiri inotaridza kukanganisa kwemabasa evanhu, kubva kuguruva panzvimbo dzekuvaka kusvika kune mafiibhi uye zvimedu zvepurasitiki zvinoburitswa nemafekitari, izvo zvinoumba chokwadi chekusvibiswa kwemvura kwemazuva ano.
Nzira dzekukurumidza kuona dzakaturikwa dzakasimba dzinosanganisira kushandiswa kwemamita akarembera akasimba, membrane/sefa bepa filtration method, centrifugal separation method, weighing method (calculation method) uye qualitative dispersion analysis method. Idzi nzira dzine maitiro adzo uye dzakakodzera kune zvakasiyana-siyana zvekuona zvinodiwa uye mamiriro. .
1. Chimbo chekuyeresa chakambomiswa: Iyi inzira yekuyeresa iri nyore uye iri nyore. Nekushandura iyo wavelength absorbance yesampuli kuita data, mhedzisiro inoratidzwa zvakananga paLCD skrini. Inokodzera kukurumidza kuwana iyo yakayerwa kukosha kwekumisikidzwa nyaya. .
2. Sefa membrane/sefa bepa sefita nzira: Nzira iyi inosanganisira kuisa sefa membrane kana sefa bepa mubhodhoro rinoyeresa, woiomesa pane imwe tembiricha uye kuiyera, uyezve kudurura mvura kuti iedzwe mubhodhoro rekuyera nesefa. membrane kana sefa bepa, kurisefa nekuriomesa, wobva wariyera. Zviri mukati menyaya yakamiswa inotsanangurwa nekuenzanisa mutsauko wehuremu pamberi uye shure. .
3. Centrifugal separation method: Yakaturikwa nyaya inoparadzaniswa ne centrifugal force yobva yapimwa. Iyi nzira iri nyore kushanda uye yakayerwa data ndeyechokwadi. Ndiyo imwe yedzakajairwa kumiswa nyaya yekumisikidza nzira. .
4. Nzira yekuyera (calculation method): Iyi nzira inoda kushandiswa kwesefa membrane, iyo yakafanana neye membrane filtration method, asi haidi nzira yekusefa. Iyo sefa membrane ine sampuli inoomeswa zvakananga uye kuyerwa. Inokodzera kukurumidza kuona zviri mukati menyaya yakamiswa. .
5. Qualitative dispersion analysis method: Iyi inzira yekuongorora yakanyatsojeka, inogona kusanganisira matanho ekushanda akaoma uye midziyo, uye yakakodzera mamiriro ezvinhu anoda kuongororwa kwakadzama. .
Paunosarudza nzira yakakodzera, zvinhu zvakadai sehukuru hwezvikamu, zvinyorwa, kugovera uye morphology, pamwe chete nekururama kwekuedzwa uye nyore kwekushanda kunoda kutariswa. Nekusarudza zvine musoro nekushandisa nzira idzi, zviri mukati mezvinwiwa kana magasi zvinogona kuongororwa uye kuyerwa nemazvo.
Zvakakosha sei kukurumidza kuona zvinhu zvakamiswa mumvura?
Yakamiswa nyaya haingokanganisa chete kujeka uye runako rwemitumbi yemvura, asi zvakare inogona kuve mutakuri wezvinhu zvinokuvadza, zvinotyisidzira chiyero che ecological uye hutano hwevanhu.
Kukosha kwekuonekwa kwezvinhu zvakamiswa mumvura:
1. Kuongorora kwezvakatipoteredza. Yakaturikwa nyaya mumvura ndechimwe chezviratidzo zvakakosha zvekuongorora hutano hwemvura uye hutano hwe ecosystem. Nekushandisa detector yakamiswa kuti ione kusungirirwa uye kuumbwa kwechinhu chakamiswa mumvura, pachena, turbidity uye mutoro wezvikafu zvemitumbi yemvura zvinogona kuongororwa, uye chiyero chekusvibiswa kwemvura uye kukanganisa kwekuchinja kwezvakatipoteredza pane ecosystem kunogona kunzwisiswa. .
2. Biological impact (Biological impact) Nyaya yakaturikwa mumvura ine simba rakananga pautano nemararamiro ezvipenyu zvemumvura. Kukwirira kwakanyanya kwezvakarembera zvimedu zvinogona kukonzera kusakwana kwechiedza mumvura, zvichikanganisa photosynthesis ye phytoplankton uye ecological mabasa e benthic organisms. Pamusoro pezvo, zvakaturikwa zvakasimba zvinogonawo kushambadza uye kutakura zvinhu zvine muchetura, zvichikonzera kukanganisa kuhove nezvimwe zvipenyu zvemumvura.
3. Utano hwevanhu. Zvimwe zvakamiswa zvakasimba, zvakaita sechepfu algae kana extracellular zvinhu zvehudiki, zvinogona kutyisidzira hutano hwevanhu. Nekutarisa zvakamiswa zvakamira mumvura, kunyanya izvo zvingave zvine hutachiona hunokuvadza, njodzi dzinogona kuitika pahutano dzinogona kuyambirwa kuve nechokwadi chekuchengetedza mvura uye hutano hwevanhu. Nokudaro, zvakakosha zvikuru kugadzirisa detector yakamiswa yakamiswa.
4. Zvekurima neindasitiri. Yakaturikwa yakaoma mumvura inewo zvakakosha pamabasa ekurima nemaindasitiri. Kunyanya kuomeswa kuoma kwemvura kunogona kukanganisa kunaka kwemvura yekudiridza, kuderedza kunaka kwevhu uye goho. Nekuburitsa maindasitiri, kutarisa zvakamiswa zvakamira mumvura kunogona kubatsira kuronda nekudzora kuvhiringika uye kusvibiswa mukubuda kwetsvina.
Naizvozvo, zvakakosha kuve nechokwadi chechokwadi uye kuvimbika kwekumisikidzwa kwezvakaoma solids. Nekuenzanisa mita yemhando yemvura yakamiswa, kurongeka uye kuenderana kwezviyero zvawanikwa zvinogona kuvandudzwa, zvichipa hwaro hwakavimbika hwekutarisira nharaunda yemvura uye kutarisa kwemhando yemvura. .
Muchidimbu, chinangwa uye kukosha kwekuona zvakamiswa zvakasimba hakugumiri pakunzwisisa kunaka kwemvura, asi zvinosanganisirawo kuchengetedza zviwanikwa zvemvura, kuchengetedza kuenzanisa kwezvakatipoteredza, kuve nechokwadi chehutano hwevanhu, uye kuongorora kunaka kwemvura. Icho chikamu chakakosha chekutarisa kunaka kwemvura.
Nekufambira mberi kwe tekinoroji, mamwe magadzirirwo ari nyore uye anoshanda akaunzwa. Iyo inotakurika yakamiswa solids mita LH-P3SS chiridzwa chakagadzirwa uye chakagadzirwa neLianhua kuona zviri mukati mezvakarembera zvimedu mumvura. Iyi mita yemhando yemvura inoshandiswa zvakanyanya mukugadzwa kwezvakaremerwa zvimedu mutsvina, kuchengetedza kwezvakatipoteredza, simbi, inotenderera mvura, indasitiri yemakemikari uye mamwe maindasitiri. Ichi chiridzwa chinotora advanced spectrophotometric tekinoroji kuti isarudze otomatiki yakanakisa wavelength, kurerutsa maitiro ekushanda, kunatsiridza kunyatsoona kwekuona, uye nekuvandudza zvakanyanya kushanda zvakanaka.
Zvinokosha kucherechedza kuti kutsunga kwezvakarembera zvakaomeswa mumvura kuri kure nemutambo wakapfava wenhamba. Izvo zvinoenderana nehutano hwezvakatipoteredza nharaunda uye kugara kwevanhu. Kukwirira kwezvakaremerwa zvimisikidzwa hakungodzikisi chete kugona kuzvichenesa kwemitumbi yemvura, kuderedza kupihwa kweokisijeni yakanyungudika mumvura, uye kuisa njodzi kune zvipenyu zvemumvura, asi zvakare kuwedzera mutoro pazvivakwa zvekuchenesa tsvina uye kukanganisa kushanda uye mutengo we kuchenesa tsvina. Naizvozvo, kutarisisa kwepedyo kwezvakaremerwa zvimedu hazvisi chinhu chakakosha chekuchengetedzwa kwezvakatipoteredza, asiwo chivimbiso chakakosha chekusimudzira kwakasimba.
