Semushonga unobatanidza mvura unoshandiswa zvakanyanya mukurapa mvura, PAC inoratidza kugadzikana kwakanaka kwemakemikari patembiricha yemumba uye ine pH yakawanda inoshandiswa. Izvi zvinobvumira PAC kuti iite nekukurumidza uye igadzire maruva ealum painorapa mvura yakasiyana-siyana, nokudaro ichibvisa zvinosvibisa mumvura. Mukurapa mvura yakasviba mumaindasitiri, PAC ine simba guru pakubvisa zvinhu zvinokuvadza zvakaita sephosphorus, ammonia nitrogen, COD, BOD uye heavy metal ions. Izvi zvinonyanya kukonzerwa nekukwanisa kwakasimba kwePAC kusanganisa mvura, iyo inokwanisa kusanganisa zvinhu izvi zvinokuvadza kuita zvidimbu zvikuru kuburikidza nekudzvanya nekukomba, zvichiita kuti zviite nyore uye kusefa.
PAM: chombo chakavanzika chekugadzirisa flocculation
Pamwe chete nePAC, PAM inoita basa rinokosha mukurapa mvura yakasviba. Senzira yepolymer flocculant, PAM inogona kuvandudza flocculation effect nekugadzirisa huremu hwayo hwemamorekuru, ionicity uye ionic degree. PAM inogona kuita kuti floc dzive dzakatetepa uye kuwedzera kumhanya kwesedimentation, nokudaro ichivandudza kuchena kwemvura. Kana dosage yePAM isina kukwana kana yakawandisa, floc dzinogona kusuduruka, zvichikonzera hunhu hwemvura ine madhaka.
Kutonga kushanda kwePAC nePAM kuburikidza nemamiriro ezvinhu efloc
Tarisa saizi yemaflocs: Kana maflocs ari madiki asi akapararira zvakaenzana, zvinoreva kuti chiyero chemuyero wePAM nePAC hachina kurongeka. Kuti mhedzisiro ive nani, chiyero chePAC chinofanira kuwedzerwa nemazvo.
Ongorora mhedzisiro yekunyungudika: Kana zvinhu zvakasimba zvakamiswa zvakakura uye mhedzisiro yekunyungudika yakanaka, asi supernatant yemhando yemvura yakasvibira, izvi zvinoratidza kuti PAC haina kuwedzerwa zvakakwana kana kuti chiyero chePAM chisina kukodzera. Panguva ino, unogona kufunga nezvekuwedzera dosage yePAC uku uchichengetedza chikamu chePAM chisina kuchinja uye kuramba uchicherechedza mhedzisiro yacho.
Tarisa chimiro cheflocs: Kana flocs dzakakora asi mvura yakasviba, chiyero chePAM chinogona kuwedzerwa zvakakodzera; kana dongo riri diki uye supernatant yakasviba, zvinoratidza kuti chiyero chePAM hachina kukwana, uye chiyero chayo chinofanira kuwedzerwa zvakakodzera.
Kukosha kwekuyedzwa kwechirongo (kunonziwo kuyedzwa kwechirongo): Mukuyedzwa kwechirongo, kana tsvina ikawanikwa pamadziro echirongo, zvinoreva kuti PAM yakawandisa yawedzerwa. Saka, chiyero chayo chinofanira kuderedzwa zvakakodzera.
Kuongororwa kwekujeka: Kana zvinhu zvakasimba zvakamiswa zvakanaka kana kuti zvakakora, kana supernatant yakajeka kwazvo, zvinoreva kuti chiyero chemuyero wePAM nePAC chakanakira.
Muchidimbu, kuti tiwane mhedzisiro yakanaka ye flocculation, chiyero chePAC nePAM chinofanira kudzorwa nekugadziriswa nokungwarira. Kuburikidza nekutarisa nekuyedza, tinogona kutonga nemazvo mhedzisiro yekushandiswa kwezviviri izvi, nokudaro tichigadzirisa maitiro ekuchenesa tsvina. Mukushandiswa kwazvino, zvakakosha kufunga zvakakwana nezvemamiriro chaiwo emhando yemvura, zvinodiwa pakurapa, zviyero zvemidziyo nezvimwe zvinhu kuti tigadzire hurongwa hwekuenzanisa makemikari. Pamusoro pezvo, kutarisisa kwakakwana kunofanirwa kupihwa pakuchengetwa, kutakurwa uye kugadzirira kwePAC nePAM kuti kuve nechokwadi chekushanda uye kuchengetedzeka kwemishonga.
