Chii chinonzi Ferric Chloride inoshandiswa pakurapa mvura?

Ferric Chlorideikemikari inosanganiswa ine fomula FeCl3. Inoshandiswa zvakanyanya mumagadzirirwo ekurapa kwemvura se coagulant nekuda kwekubudirira kwayo mukubvisa tsvina uye tsvina kubva mumvura uye kazhinji inoshanda zvirinani mumvura inotonhora kupfuura alum. Chikamu che93% cheferric chloride chinoshandiswa mukuchenesa mvura, kureva mvura yetsvina, tsvina, mvura yekubikisa uye yekunwa. Ferric chloride inonyanya kushandiswa mune yakasimba fomu semushonga wemvura uye tsvina yemvura.

Kushandiswa kweferric chloride mukurapa kwemvura:

1. Coagulation uye Flocculation: Imwe yekushandiswa kwekutanga kweferric chloride mukurapwa kwemvura ndeye coagulant. Kana yawedzerwa kumvura, ferric chloride inopindirana nemvura kuti ibudise ferric hydroxide uye iyo yekupedzisira adsorbs yakamiswa zvimedu, organic matter, uye kumwe kusvibiswa kuumba zvidimbu zvakakura, zvinorema zvinonzi flocs. Aya ma flocs anogona kuzogara zviri nyore panguva yekusevha kana kusefa, zvichibvumira kubviswa kwetsvina kubva mumvura.

2. Phosphorus Removal: Ferric chloride inonyanya kushanda pakubvisa phosphorus kubva mumvura. Phosphorus chinhu chakajairika chinowanikwa mumvura yetsvina, uye mazinga akawandisa anogona kutungamira kune eutrophication mukugamuchira miviri yemvura. Ferric chloride inoumba insoluble complexes ine phosphorus, iyo inogona kubva yabviswa kuburikidza nekunaya kana kusefa, zvichibatsira kuderedza phosphorus mazinga mumvura.

3. Heavy Metal Removal: Ferric chloride inoshandiswawo kubvisa simbi inorema, yakadai se arsenic, lead, uye mercury, kubva mumvura. Masimbi aya anogona kuve ane muchetura zvakanyanya uye anokonzeresa njodzi dzehutano kana aripo mumvura yekunwa. Ferric chloride inoumba insoluble metal hydroxides kana simbi oxychlorides, iyo inogona kubva yabviswa kuburikidza nekunaya kwemvura kana kusefa, zvichinyatso kudzikisa kuwanda kwesimbi inorema mumvura.

4. Ruvara uye Kunhuhwirira Kubviswa: Ferric chloride inoshanda mukubvisa ruvara uye kunhuhwirira-kunokonzera masanganiswa kubva mumvura. Inopa oxidizes organic compounds inokonzera ruvara uye kunhuwa, ichiiputsa kuita zviduku, zvisingarambiki. Iyi nzira inobatsira kuvandudza kunaka kwemvura, ichiita kuti ive yakakodzera kunwa, maindasitiri, kana nhandaro.

5. pH Kugadziriswa: Nokudzora pH, ferric chloride inogona kukwidziridza kushanda kwemamwe maitiro ekurapa, akadai sekubatanidza, flocculation, uye disinfection. Yakanaka pH renji inogona kubatsira kugadzira iyo yakanaka mamiriro ekubvisa tsvina uye zvinosvibisa kubva mumvura.

6. Disinfection Byproduct Control: Ferric chloride inogona kubatsira kudzora kuumbwa kwe disinfection byproducts (DBPs) panguva yekurapa kwemvura. Kana yakashandiswa pamwe chete nemishonga inouraya utachiona seklorini, ferric chloride inogona kuderedza kuumbwa kweDBPs yakadai se trihalomethanes (THMs) uye haloacetic acids (HAAs), iyo inogona kukonzera kenza. Izvi zvinovandudza kuchengetedzwa kwese uye kunaka kwemvura yekunwa.

7. Sludge Dewatering: Ferric chloride inoshandiswawo mukugadzirisa sludge dewatering mumiti yekuchenesa mvura. Inobatsira kugadzirisa sludge nekusimudzira kuumbwa kwehombe, denser flocs, iyo inogara nekukurumidza uye kusunungura mvura zvakanyanya. Izvi zvinoguma nekuvandudzwa kwekuita kwemvura uye kuderedza sludge volume, zvichiita kuti zvive nyore uye zvakanyanya mari-inoshanda kubata uye kurasa tsvina.

Ferric Chloride inobata basa rakakosha mune dzakasiyana siyana dzekugadzirisa mvura, kusanganisira coagulation, phosphorus uye inorema simbi kubviswa, ruvara uye kunhuwa kubviswa, pH kugadzirisa, disinfection byproduct control, uye sludge dewatering. Kusarudzika kwayo uye kushanda kwayo kunoita kuti ive kemikari yakakosha mukurapa kwesese mvura yekunwa uye mvura yetsvina, ichibatsira kuve nechokwadi chekuchengetedza, kunaka, uye kusimba kwezviwanikwa zvemvura.
