Chii chinoshandiswa neFerric Chloride pakuchenesa mvura?

Ferric Chlorideikemikari ine fomura yeFeCl3. Inoshandiswa zvakanyanya mukurapa mvura se coagulant nekuda kwekushanda kwayo mukubvisa tsvina nemvura uye inowanzo shanda zviri nani mumvura inotonhora pane alum. Inenge 93% ye ferric chloride inoshandiswa mukurapa mvura, kureva mvura yakasviba, tsvina, mvura yekubikisa nemvura yekunwa. Ferric chloride inonyanya kushandiswa muchimiro chakasimba semhinduro yekurapa mvura netsvina.

Kushandiswa kwe ferric chloride mukurapa nemvura:

1. Kubatanidza uye Kubatanidza: Imwe yenzira huru dzekushandisa ferric chloride mukuchenesa mvura ndeyekusanganisa mvura. Kana yawedzerwa mumvura, ferric chloride inosangana nemvura kuti igadzire ferric hydroxide uye yekupedzisira inonyudza zvidimbu zvakamiswa, zvinhu zvakasikwa, nezvimwe tsvina kuti igadzire zvidimbu zvakakura, zvinorema zvinonzi flocs. Maflocs aya anogona kugara nyore nyore panguva yekusefa kana kusefa, zvichibvumira kubviswa kwetsvina mumvura.

2. Kubviswa kweFosforasi: Ferric chloride inonyanya kushanda mukubvisa phosphorus mumvura. Phosphorus chinhu chinowanikwa mumvura yakasviba, uye huwandu hwakawanda hwezvinhu hunogona kukonzera kuumbwa kwemvura yakawanda mumvura. Ferric chloride inoita phosphorus isinganyunguduke, iyo inogona kubviswa kuburikidza nemvura inonaya kana kusefa, zvichibatsira kuderedza huwandu hwephosphorus mumvura.

3. Kubviswa kwesimbi inorema: Ferric chloride inoshandiswawo kubvisa simbi dzinorema, dzakadai searsenic, lead, uye mercury, mumvura. Simbi idzi dzinogona kuva nechepfu zvakanyanya uye dzingave nenjodzi huru kuhutano kana dziri mumvura yekunwa. Ferric chloride inogadzira simbi isinganyungudike kana metal oxychlorides, iyo inogona kubviswa kuburikidza nekunaya kwemvura kana kusefa, zvichideredza huwandu hwesimbi dzinorema mumvura.

4. Kubvisa Ruvara Nekunhuhwirira: Ferric chloride inoshanda mukubvisa zvinhu zvinokonzera ruvara nehwema mumvura. Inooxidize zvinhu zvinokonzera ruvara nehwema, ichizviparadzanisa kuita zvinhu zvidiki, zvisinganyanyi kuipa. Maitiro aya anobatsira kuvandudza kunaka kwemvura, zvichiita kuti ive yakakodzera kunwa, maindasitiri, kana kunakidzwa.

5. Kugadziriswa kwepH: Nekudzora pH, ferric chloride inogona kugadzirisa mashandiro emamwe maitiro ekurapa, akadai sekuvharika, kupwanyika, uye kuuraya utachiona. Huwandu hwakanaka hwepH hunogona kubatsira kugadzira mamiriro akakodzera ekubvisa tsvina nemvura.

6. Kudzora Kuuraya Mabhakitiriya: Ferric chloride inogona kubatsira kudzora kuumbwa kwezvipembenene zvinouraya mabhakitiriya (DBPs) panguva yekurapa nemvura. Kana ikashandiswa pamwe chete nemishonga inouraya mabhakitiriya yakaita sechlorine, ferric chloride inogona kuderedza kuumbwa kweDBP dzakadai setrihalomethanes (THMs) uye haloacetic acids (HAAs), izvo zvinogona kukonzera kenza. Izvi zvinovandudza kuchengetedzeka kwese uye kunaka kwemvura yekunwa.

7. Kubvisa Mvura muMarara: Ferric chloride inoshandiswawo mukubvisa mvura mumasango ekuchenesa mvura. Inobatsira kugadzirisa matope nekukurudzira kuumbwa kwematope makuru, akasimba, ayo anogadzikana nekukurumidza uye anoburitsa mvura zviri nani. Izvi zvinoita kuti mvura ishande zvakanaka uye kuderedza huwandu hwematope, zvichiita kuti zvive nyore uye zvisingadhuri kubata nekurasa tsvina.

Ferric Chloride inoita basa rakakosha mukurapa mvura, kusanganisira kuonda, kubvisa phosphorus nesimbi inorema, kubvisa ruvara nekunhuhwirira, kugadzirisa pH, kudzora hutachiona kubva pakugadzirwa, uye kubvisa tsvina. Kushanda kwayo kwakasiyana-siyana uye kushanda kwayo kunoita kuti ive kemikari inokosha mukurapa mvura yekunwa nemvura yakasviba, zvichibatsira kuona kuchengetedzeka, mhando, uye kugara kwenguva refu kwezviwanikwa zvemvura.
