Chii chinonzi ferric chloride chinoshandiswa pakurapwa kwemvura?

Ferric chlorideiri kemikari yakafanana neiyo formula fec3. Iyo inoshandiswa zvakanyanya mumvura yekurapa kwemvura seyakaitwa nekuda kwekushanda kwayo mukubvisa kusvibiswa uye zvinosvibisa kubva mumvura uye kazhinji zvinoshanda zviri nani mumvura inotonhora kupfuura alum. Vanenge 93% yeFerric Chloride inoshandiswa pakurapwa kwemvura, kureva kuti yakatsva mvura, sewage, mvura yekubheka uye kumwa mvura. Ferric chloride inonyanya kushandiswa muchimiro chakasimba semhinduro yemvura uye kurapwa kwemvura.

Kushandiswa kweFerric Chloride mumvura kurapwa:

1. Cogulation uye flocculation: imwe yeiyo yekutanga kushandiswa kweFerric chloride mukurapwa kwemvura kwakafanana nekukasira. Kana uwedzeredzwa kumvura, Ferric Chloride anowana nemvura kuti igadzire Ferric Hydroxide uye maAdter Adsorbs akamiswa zvimedu, zvine hungwaru, uye zvimwe zvinhu zvakakura zvinonzi zviyero zvehombodo. Aya maFlocs anogona kubva pakugadzirisa zviri nyore panguva yekunyora kana maitiro efaira, achibvumira kubviswa kwekusachena kubva mumvura.

2. Phesphorus kubvisa: Ferric Chloride inoshanda zvakanyanya mukubvisa phosphorus kubva mumvura. Phosphorous huwandu hwakajairika hunowanikwa mumvura ine marara, uye huwandu hwakawanda hunogona kutungamira mukushanduka kwemvura mukugamuchira miviri yemvura. Ferric chloride mafomu ezvekuita zvisikwa ne phosphorous ne phosphorous, iyo inogona kubviswa kuburikidza nekutsvaira kana kuti filtration, ichibatsira kuderedza phosphorus maza emvura.

3 Aya masimbi anogona kuve ane chepfu uye anoisa njodzi dzehutano hombe kana iripo mumvura yekunwa. Ferric chloride mafomu ezvemukati medhazhi ehuswa

4 Iyo oxidize compic compound yemavara uye kunhuhwirira, kuvapwanya pasi mune zvidiki zvidiki, zvisingakoshi zvinhu zvinopesana. Kuita uku kunobatsira kuvandudza hunhu hwemvura, zvichiita kuti ive yakakodzera kunwa, maindasitiri, kana ekuvaraidza.

5. PH Adernment: Nekudzora iyo pH, ferric chloride inogona kuongorora mashandiro emamwe maitiro ekurapa, akadai sekubatanidzwa, uye kusagadzikana. Yakakodzera pP range inogona kubatsira kugadzira mamiriro akakodzera ekubviswa kwekusachena uye zvinosvibisa kubva kumvura.

6. Kukundwa Byproduct Kudzora: Ferric Chloride inogona kubatsira kudzora kuumbwa kwekunyepedzera nekudonha) panguva yekurapwa kwemvura. Kana ichishandiswa pamwe chete nevanovhiringidza senge chlorine, ferric chlorine inogona kuderedza kuumbwa kweDBPs (TME) uye haloacetic acids (Haas), ayo anogona kunge ari carcinogens. Izvi zvinovandudza kuchengetedza kwakazara uye kunaka kwemvura yekunwa.

7 Inobatsira kumamiriro ezvinhu nekusimudzira kuumbwa kweakakura, denser flocs, iyo inogadzirisa zvakanyanya nekukurumidza uye kusunungura mvura zvakanyatsoshanda. Izvi zvinoguma zvaitika mukuvandudzwa kwekuita uye kuderedza sludge vhoriyamu, zvichiita kuti zvive nyore uye zvakanyanya mutengo wekubata uye kurasa sludge.

Ferric Chloride anotora basa rakakosha mune dzakasiyana siyana dzekurapa kwemvura, kusanganisira kabhuku uye phesphorus nekubvisa simbi, ruvara nekubvisa, kusatadza kudzora, uye kutsvedza. Kuwanikanya uye kushanda kwaro kunoita kuti ive yakakosha kamiriri mukurapa kwemvura nemvura uye marara, kubatsira kuve nechokwadi chekuchengetedza, hunhu, uye hwekutsigira zviwanikwa zvemvura.
