Turbidity mumvura yepamusoro

Chii chinonzi turbidity?
Turbidity (Turbidity) zvinoreva mwero wekuvharira kwemhinduro yekufamba kwechiedza, izvo zvinosanganisira kupararira kwechiedza nechinhu chakarembera uye kutorwa kwechiedza nemamorekuru ane solute.
Turbidity iparameter inotsanangura nhamba yezvimedu zvakaturikwa mumvura. Izvo zvine chekuita nezvinhu zvakaita sezviri mukati, saizi, chimiro, uye refractive index yezvinhu zvakamiswa mumvura. Mukuyedzwa kwemhando yemvura, turbidity chiratidzo chakakosha, chinogona kuratidza kusungirirwa kwezvakarembera zvakamira mumvura uye zvakare imwe yehwaro hwekunzwa kwevanhu kuongororwa kwemhando yemvura. Turbidity inowanzopimwa nekuyera huwandu hwechiedza chakaparadzirwa netwunhu mumvura kana chiedza chikapfuura nemumuenzaniso wemvura. Izvi zvidiki zvinhu zvinowanzova zvidiki, zvine saizi kazhinji pahurongwa hwema microns uye pazasi. Iyo turbidity inoratidzwa nezviridzwa zvemazuva ano inowanzoparadzira turbidity, uye unit iNTU (Nephelometric Turbidity Units). Chiyero che turbidity chakanyanya kukosha pakuongorora kunaka kwemvura yekunwa, nekuti haina hukama chete nekujeka kwemvura, asi zvakare nenzira isina kunanga inotaridza huwandu hwehuwandu hwema microorganisms mumvura, inokanganisa disinfection mhedzisiro.
Turbidity chiyero chinoenderana nekuwanda kwechiedza chinogona kupfuura nemumuenzaniso wemvura. Iyo yakakwirira iyo turbidity, iyo shoma mwenje ichapfuura nemumuenzaniso uye mvura ichaonekwa "cloudier". Kunyanya huturu hunokonzerwa nezvikamu zvakasimba zvakaturikwa mumvura, izvo zvinoparadzira chiedza panzvimbo yekuchipfuudza mumvura. Zvimiro zvemuviri zvezvimedu zvakamiswa zvinogona kukanganisa zvachose turbidity. Zvimedu zvakakura zvinoparadzira chiedza uye zvinonangisa mberi, nokudaro zvichiwedzera turbidity nekukanganisa kufambiswa kwechiedza mumvura. Particle size inokanganisawo kunaka kwechiedza; zvimedu zvihombe zvinoparadzira masaisai echiedza akareba zviri nyore pane mapfupi ewavelength, nepo zvidimbu zvidiki zvine mhedzisiro yakakura yekuparadzira pamasaisai mapfupi. Kuwedzera kugadzirwa kwechikamu kunoderedzawo kufambiswa kwechiedza sezvo mwenje uchisangana nenhamba yakawedzera yezvimedu uye uchifamba nzendo pfupi pakati pezvimedu, zvichikonzera kupararira kwakawanda pachikamu chimwe nechimwe.

Kuonekwa musimboti
Turbidity 90-degree scattering method inzira inowanzoshandiswa kuyera turbidity yemhinduro. Iyi nzira inobva pane chiitiko chekuparadzira chinotsanangurwa neLorentz-Boltzmann equation. Iyi nzira inoshandisa photometer kana photometer kuyera kusimba kwechiedza chinopfuura nemumuenzaniso pasi pekuedzwa uye kusimba kwechiedza chakaparadzirwa nemuenzaniso mu 90-degree scattering direction, uye inoverenga turbidity yemuenzaniso zvichienderana nechiyero chakayerwa. Theorem yekuparadzira inoshandiswa nenzira iyi ndeiyi: Mutemo weBeer-Lambert. Iyi theorem inotaura kuti pasi pekuita kwemhepo inopenya yakafanana, mhinduro ye electro-optical mukati meuniti urefu inoderera ne exponential function ye optical path urefu, unova mutemo wekare weBeer-Lambert. Mune mamwe mazwi, maranzi emwenje anorova zvimedu zvakamiswa mumhinduro anopararira kakawanda, nemimwe mwaranzi ichipararira pa90-degree angles. Paunenge uchishandisa nzira iyi, chiridzwa chinoyera chiyero chekusimba kwechiedza chakapararira nezvikamu izvi pa90-degree angle kusvika kuhukuru hwechiedza chinopfuura nemuenzaniso pasina kupararira. Sezvo kuwanda kwezvimedu zve turbidity kunowedzera, kusimba kwechiedza chakapararira chichawedzerawo, uye reshiyo ichave yakakura, saka, saizi yereshiyo inoenzana nenhamba yezvimedu mukumiswa.
Muchokwadi, pakuyera, sosi yemwenje inounzwa yakatwasuka mumuenzaniso uye sampuli inoiswa panzvimbo ine kona yekuparadzira ye90 °. Iko turbidity kukosha kwemuenzaniso inogona kuwanikwa nekuyera kusimba kwechiedza kuyerwa zvakananga pasina kupfuura nesainzi uye 90 ° yakapararira chiedza chechiedza chinogadzirwa mumuenzaniso ne photometer, uye yakasanganiswa ne colorimetric calculation method.
Iyi nzira ine hupamhi hwepamusoro uye inoshandiswa zvakanyanya mukuyera turbidity mumvura, tsvina, chikafu, mishonga uye minda yezvakatipoteredza.

Chii chinonyanya kukonzera turbidity mumvura yepamusoro?
Turbidity iri pamusoro pemvura inonyanya kukonzerwa nezvinhu zvakamiswa mumvura. 12
Zvinhu zvakaturikwa izvi zvinosanganisira silt, ivhu, organic matter, inorganic matter, floating matter and microorganisms, etc., izvo zvinodzivirira chiedza kupinda mumvura yemvura, nokudaro zvichiita kuti mvura iite turbid. Idzi zvinhu zvinogona kubva mumaitiro echisikigo, semadutu, kutsvaira kwemvura, kuvhuvhuta nemhepo, zvichingodaro, kana kubva muzviitiko zvevanhu, sekurima, maindasitiri, uye kusvibiswa kwemaguta. Chiyero che turbidity chinowanzova mune chimwe chikamu kune zviri mukati mezvakarembera zvimedu mumvura. Nekuyera kusimba kwechiedza chakapararira, kuwanda kwezvakarembera mumvura zvinogona kunzwisiswa.
Kuyera turbidity
Lianhua turbidity mita LH-P305 inoshandisa nzira ye90 ° yakapararira yechiedza, ine chiyero chekuyera 0-2000NTU. Iwo maviri wavelengths anogona kuchinjika otomatiki kudzivirira kukanganiswa kwemvura chromaticity. Chiyero chacho chiri nyore uye migumisiro yakarurama. Nzira yekuyera sei turbidity
1. Batidza handheld turbidity mita LH-P305 kuti utange kupisa, iyo unit iNTU.
2. Tora 2 yakachena colorimetric tubes.
3. Tora 10ml yemvura yakasvibiswa uye uiise muNo. 1 colorimetric tube.
4. Tora 10ml yemuenzaniso uye uiise mu colorimetric tube Nhamba 2. Pukuta rusvingo rwekunze rwakachena.
5. Vhura tangi ye colorimetric, isa muNo.
6. Bvisa iyo Nhamba 1 colorimetric tube, isa muNo.
Kushandisa uye pfupiso
Turbidity chiyero chakakosha chemhando yemvura nekuti ndicho chiratidzo chinonyanya kuoneka chekuti "kuchena" kwetsime remvura. High turbidity inogona kuratidza kuvepo kwemvura inosvibisa iyo inokuvadza kuhupenyu hwevanhu, mhuka nezvirimwa, kusanganisira mabhakitiriya, protozoa, zvinovaka muviri (senge nitrate uye phosphorus), mishonga yezvipembenene, mercury, lead uye mamwe masimbi. Kuwedzera turbidity mumvura pamusoro pemvura kunoita kuti mvura isakodzere kudyiwa nevanhu uye inogona kupawo hutachiona hwemvura hwakadai sehutachiona hunokonzera zvirwere kune pamusoro pemvura. Kuwanda kwemarara kunogonawo kukonzerwa nemvura yetsvina inobva mumasuweji, kuyerera kwemumaguta, uye kukukurwa kwevhu kubva mubudiriro. Naizvozvo, kuyerwa kwe turbidity kunofanirwa kushandiswa zvakanyanya, kunyanya mumunda. Zviridzwa zviri nyore zvinogona kufambisa kutariswa kwemamiriro emvura nezvikamu zvakasiyana uye pamwe chete kuchengetedza kuvandudzwa kwenguva refu kwezviwanikwa zvemvura.
