Ko Poly Aluminium Chloride inobvisa sei zvinosvibisa mumvura?

Poly Aluminium Chloride(PAC) ikemikari yemakemikari inoshandiswa zvakanyanya mukurapa mvura netsvina nekuda kwekushanda kwayo mukubvisa zvinosvibisa.Maitiro ayo ekuita anosanganisira akati wandei matanho akakosha anobatsira pakucheneswa kwemvura.

Chekutanga, PAC inoita seyakagwinya mukugadzirisa mvura.Coagulation maitiro ekudzikamisa macolloidal particles uye kumiswa mumvura, zvichiita kuti aungane pamwe chete uye kuumba zvidimbu zvakakura zvinonzi flocs.PAC inozadzisa izvi nekumisa mhosva dzisina kunaka pamusoro pezvimedu zvecolloidal, izvo zvinovatendera kuti vauye pamwechete uye vagadzire flocs kuburikidza nemaitiro anonzi charge neutralization.Aya flocs anobva aita nyore kubvisa kuburikidza neanotevera mafirita maitiro.

Kuumbwa kwemaflocs kwakakosha pakubviswa kwezvakasiyana zvinosvibisa kubva mumvura.PAC inobvisa zvine mutsindo zvinhu zvakaturikwa, senge zvidimbu zvevhu, silt, uye organic matter, nekuzvibatanidza mumaflocs.Izvi zvakamiswa zvakasimba zvinogona kukonzeresa kuvhiringika kwemvura, zvichiita kuti iite seine makore kana kuti murky.Nekuunganidza zvimedu izvi kuita zvidimbu zvakakura, PAC inofambisa kubviswa kwavo panguva yekunyungudika uye kusefa, zvichikonzera kujeka kwemvura.

Uyezve, PAC inobatsira mukubvisa zvinhu zvakanyungudutswa organic zvinhu uye zvinokonzeresa mavara kubva mumvura.organic zvinhu zvakanyungudutswa, senge humic uye fulvic acids, zvinogona kupa zvinonaka uye hwema zvisingafadzi kumvura uye zvinogona kuita nemishonga inouraya utachiona kuita zvinokuvadza zvekuuraya utachiona kubva kune-zvigadzirwa.PAC inobatsira kubatanidza uye kushambadza aya organic makomisheni pamusoro peiyo yakaumbwa flocs, nekudaro ichidzikisa kunyura kwavo mumvura yakabikwa.

Pamusoro peiyo organic matter, PAC inogona zvakare kunyatsobvisa zvakasiyana siyana inorganic tsvina kubva mumvura.Izvi zvinosvibisa zvinogona kusanganisira simbi dzinorema, dzakadai se arsenic, lead, uye chromium, pamwe nemamwe anion akaita sephosphate uye fluoride.PAC inoshanda nekugadzira isingagadzike simbi hydroxide precipitates kana neadsorbing maion simbi pamusoro payo, nekudaro ichidzikisa kunyura kwavo mumvura yakacheneswa kusvika kumatanho anoenderana nemirairo.

Uyezve, PAC inoratidza zvakanakira kupfuura mamwe macoagulants anowanzo shandiswa mukurapwa kwemvura, sealuminium sulfate (alum).Kusiyana nealum, PAC haichinji zvakanyanya pH yemvura panguva yekubatanidza, izvo zvinobatsira kudzikisa kudiwa kwepH kugadzirisa makemikari uye kuderedza mutengo wese wekurapa.Pamusoro pezvo, PAC inogadzira sludges shoma kana ichienzaniswa nealum, zvichikonzera kuderera kwemitengo yekurasa uye kukanganisa kwezvakatipoteredza.

Pakazere, Poly Aluminium Chloride (PAC) icoagulant inoshanda zvakanyanya inoita basa rakakosha mukubviswa kwezvakasiyana zvinosvibisa mumvura.Kugona kwayo kusimudzira coagulation, flocculation, sedimentation, uye adsorption maitiro anoita kuti ive chinhu chakakosha mumasitimu ekurapa mvura pasi rese.Nekuita kuti kubviswa kwezvakarembera zvakamira, zvakanyungudutswa organic zvinhu, mavara-akonzeresa makomisheni, uye inorganic tsvina, PAC inobatsira kuburitsa yakachena, yakajeka, uye yakachengeteka yekunwa mvura inoenderana nemirairo.Kudhura kwaro, nyore kushandisa, uye kushomeka kunokanganisa pamvura pH inoita kuti ive sarudzo inosarudzika yezvidyarwa zvekuchenesa mvura zvichitsvaga mhinduro dzakavimbika uye dzakasimba dzekuchenesa mvura.
