Poly Aluminium Chloride inoshanda sei?

Munyika yekuchenesa mvura,Poly Aluminium Chloride(PAC) yakabuda seyakasiyana-siyana uye inoshanda coagulant.Nekushandiswa kwakawanda mukuchenesa mvura yekunwa uye zvidyarwa zvekuchenesa mvura, PAC iri kugadzira masaisai ekugona kwayo kujekesa mvura nekubvisa zvinosvibisa.Muchinyorwa chino, tinoongorora mashandiro ePAC uye kukosha kwayo mundima yekuchenesa mvura.

Iyo Chemistry Kuseri kwePAC:

Poly Aluminium Chloride ikemikari inoumbwa nealuminium uye chlorine, ine fomula AlnCl(3n-m)(OH)m.Hunhu hwayo hwakasiyana-siyana hunobva pakuti inogona kuvapo nenzira dzakasiyana-siyana zvichienderana nehuwandu hwealuminium-kune-chloride uye dhigirii repolymerization.Misiyano iyi inobvumira PAC kuti ienderane neyakasiyana-siyana yematambudziko ekugadzirisa mvura.

Coagulation uye Flocculation:

Basa rekutanga rePAC mukurapa kwemvura kugadzikana uye kuyerera.Kana PAC yawedzerwa kumvura yakasvibirira, inoenda kune hydrolysis.Munguva iyi, inoumba aluminium hydroxide flocs, iyo inoshanda zvakanyanya pakubata tsvina yakamiswa mumvura.Iyo aluminium hydroxide flocs inoita semagineti madiki, inokwezva uye inosunga pamwechete zvimedu zvakaita setsvina, mabhakitiriya, uye organic zvinhu.

Kubvisa Kusvibiswa:

PAC's coagulation-flocculation mechanism inobatsira mukubviswa kwetsvina dzakasiyana kubva mumvura, kusanganisira yakamiswa yakasimba, colloids, uye kunyangwe zvimwe zvakanyungudika.Sezvo flocs dzichikura uye dzichiremerwa, dzinogara pasi petangi rekurapa kuburikidza nesedimentation kana kubatwa zviri nyore nemasefa.Izvi zvinoguma nekugadzirwa kwemvura yakachena uye yakachena.

pH Kusarerekera:

Imwe yemabhenefiti akakosha ePAC ndeye pH kusarerekera kwayo.Kusiyana nechinyakare coagulants senge aluminium sulfate kana ferric chloride, inogona kuchinja zvakanyanya pH yemvura, PAC inochengetedza pH mazinga akagadzikana.Izvi zvinoderedza kudiwa kwemamwe makemikari kugadzirisa pH, kurerutsa maitiro ekurapa uye kuderedza mitengo.

Zvakanakira Kushandisa PAC:

Kunyatsogona: PAC inoshanda zvinobudirira muhuwandu hwakawanda hwehunhu hwemvura uye turbidities.

Versatility: Inogona kushandiswa kune ese ekutanga uye epamusoro mvura kurapwa.

Yakaderera Residuals: PAC inogadzira mashoma sludge ne-zvigadzirwa, ichideredza mari yekurasa.

Mutengo-Unoshanda: Kushanda kwayo uye kusarerekera kwepH kunoita kuti ive sarudzo inodhura-inoshanda kune zvidyarwa zvekuchenesa mvura.

Chengetedzo: PAC inowanzoonekwa yakachengeteka kubata kupfuura mamwe macoagulants.

Zvikumbiro zvePAC:

PAC inowana kushandiswa kwakakura mumaindasitiri akasiyana, anosanganisira kurapwa kwemvura yemunisiparati, maindasitiri emarara emvura, uye kunyangwe mumaindasitiri emapepa nemachira.Kukwanisa kwayo kubvisa huwandu hwakawanda hwehutachiona hunoita kuti ive chinhu chakakosha chekuchengetedza mvura yakachena uye yakachengeteka.

Mukupedzisa, Poly Aluminium Chloride (PAC) inoshamisa yekurapa mvura mhinduro inoshanda kuburikidza nekubatana uye flocculation.Kushanda kwayo, kuita kwakasiyana-siyana, uye kusarerekera kwepH kwakaiisa sesarudzo yakasarudzika yezvivakwa zvekurapa mvura pasi rese.Sezvo kudiwa kwemvura yakachena kuri kuramba kuchikura, PAC inoramba iri mutambi akakosha mukuona kuwanikwa kwemvura yakachengeteka uye inonwika kunharaunda dzepasirese.
