Gwaro Rakakwana Rekurapa Mvura Zvinobudirira
Masisitimu ekurapa mvura anonyanya kushandisa nzira dzekubatanidza mvura nedzekupwanya mvura kuti abvise zvidimbu zvakasungirirwa, zvinhu zvipenyu, uye kuvhuvhuta mumvura. Mamwe emakemikoro anoshandiswa zvakanyanya mukuita uku ndeayaPolyaluminum Chloride (PAC)uyePolyacrylamide (PAM).
Kana zvikashandiswa pamwe chete nemazvo, PAC nePAM zvinogona kuvandudza kushanda zvakanaka kwemvura, kuderedza huwandu hwemakemikari, uye kuwedzera kushanda kwetsvina. Zvisinei, kusanganiswa kusina kunaka—sekutevedzana kwedosi kana huwandu hwayo—kunogona kuderedza kushanda zvakanaka kwekurapa.
Chinyorwa chino chinopa gwara rakakwana rehunyanzvi rekuti ungabatanidza sei PAC nePAM mukubatanidza ropa, kusanganisira misimboti, nzira dzekuyedza, nzira dzekugadzirisa, uye zvikanganiso zvakajairika zvekudzivisa.
Kunzwisisa Mabasa ePAC nePAM muCoagulation
Usati wakurukura kuti ungazvisanganisa sei, zvakakosha kunzwisisa kuti kemikari yega yega inoshanda sei mukuita kwe coagulation-flocculation.
Polyaluminum Chlorideipurasitiki inosanganiswa nepolymer inoshandiswa zvakanyanya mukurapa mvura yekunwa, kurapwa kwemvura yakasviba mumaindasitiri, uye masisitimu etsvina yemaguta.
PAC inonyanya kushanda kuburikidza nekudzora simba remagetsi uye kunyungudutsa mvura. Munzvimbo zhinji dzemvura dzechisikigo, zvidimbu zvakasungirirwa zvine machaji asina kunaka, izvo zvinoita kuti zvirambe zvakapararira uye zvichidzivirira kuti zvisagadzikane. PAC inoburitsa maion ealuminium ane charge yakanaka anodzima machaji aya. Kana zvangobviswa simba, zvidimbu zvinotanga kuungana kuita ma microflocs madiki.
Mabhenefiti ePAC
- Kugona kwakasimba kwekuonda
- Kubvisa tsvina zvinobudirira
- Kushanda kwepH yakafara
- Huremu hwetsvina hwakaderera kana tichienzanisa nemunyu wearuminiyamu wekare
- Yakakodzera kushandiswa mumvura inonwiwa uye mvura yakasviba
Zvisinei, PAC yoga inogona kuumba tumiti tudiki tunodzika zvishoma nezvishoma, ndipo panotanga kukosha PAM.
Polyacrylamideipurasitiki inonyungudika inoshandiswa kusimudzira kutenderera nekudzika. PAM inonyanya kushanda kuburikidza nekubatanidza polymer. Maketani ayo marefu emolekyuli anobatanidza ma microflocs akawanda pamwe chete, achigadzira ma flocs makuru uye akakora anodzika nekukurumidza.
Mhando dzePAM dzinoshandiswa mukurapa mvura
Kune mhando nhatu huru:
- Anionic PAM (APAM)
- Cationic PAM (CPAM)
- PAM Isina Ionic (NPAM)
Mumazhinji masisitimu ePAC + PAM, anionic PAM ndiyo inowanzo shandiswa nekuti PAC yatove ichipa positive charge neutralization.
Mabhenefiti ePAM muhurongwa hwekuvharisa ropa
- Inowedzera saizi yefloc
- Inokurumidza kudonha kwevhu
- Inovandudza kubviswa kwemvura mumarara
- Inoderedza muyero wePAC
- Inowedzera kushanda zvakanaka kwekusefa
Nei PAC nePAM Zvichishandiswa Pamwe Chete
Kushandisa PAC nePAM pamwe chete kunoita kuti pave nekubatana kwemasero eropa (synergistic coagulation-flocculation effect).
Maitiro ekuita nhanho nhanho
PAC inokanganisika zvidimbu, inodzima machaji, uye inogadzira micro-flocs.
Maketani ePAM anobatanidza ma microfloc kuita ma floc makuru.
Matanda makuru anonyura nekukurumidza mumatangi emvura.
Zvakanakira kushandisa polyaluminum chloride nepolyacrylamide pamwe chete
- Kubviswa kwetsvina yakawanda
- Nguva yekugadzikana nekukurumidza
- Kushandiswa kwemakemikari kwakaderera
- Kuderedzwa kwehuwandu hwetsvina
- Kushanda kwefirita kwakavandudzwa
Nekuda kwezvibatsiro izvi, kusanganiswa kwePAC + PAM kunoshandiswa zvakanyanya mu:
- Nzvimbo dzekuchenesa mvura yetsvina dzemuguta
- Kurapa mvura yakasviba mumaindasitiri
- Kujekesa mvura yakasviba yemugodhi
- Kurapa kwemvura yakasviba muchina wepepa
- Kujekesa mvura yekunwa
Kutevedzana Kwakarurama Kwemushonga wePAC nePAM
Chimwe chezvinhu zvakakosha pakubudirira kwekugwamba kweropa ndiko kutevedzana kwedosi. Kurongeka kwakarurama ndekwekuti:PAC yekutanga → PAM yechipiri
Nei PAC ichifanira kuwedzerwa kutanga
PAC inofanira kutanga yadzima simba rezvinhu zvinoumba ma microflocs ekutanga. Pasina danho iri, mamorekuru ePAM anongonyungudika mumvura uye haakwanise kusunga zvinhu zvinobudirira.
Matanho akajairika ekuyera dosing
- Tangi yekusanganisa nekukurumidza
- Jekiseni rePAC
- Kusanganisa nekukurumidza (masekondi 30–60)
- Jekiseni rePAM
- Kusanganisa zvishoma nezvishoma (danho re flocculation)
- Kucherwa kwevhu
⚠️ Chikanganiso chinowanzoitika:Kuwedzera PAM usati waisa PAC chikanganiso chinowanzoitika chinoita kuti floc iome uye makemikari anoshandiswa zvisina kunaka.
Chipimo chakanaka chePAC nePAM
Chiyero chinosiyana zvichienderana nemhando yemvura, hunyoro, uye huwandu hwezvinhu zvakaoma zvakamiswa.
Marudzi akajairika ndeaya anotevera
Chipimo chePAC
Mvura yekunwa: 5–50 mg/L
Mvura yakasviba yemumaindasitiri: 30–200 mg/L
Chipimo chePAM
Kazhinji yakaderera zvikuru pane PAC
Huremu hwakajairika: 0.1–3 mg/L
Mutemo mukuru
Muyero wePAM unowanzova 1/100 kusvika 1/50 yemuyero wePAC.
Kuwanda kwePAM kunogona kukonzera:
- Mafurosi anonamira
- Kugadzikana kusina kunaka
- Kuvharika kwefirita
Saka, kuyedzwa kwemubhodhoro kunodiwa kuti uone chiyero chakakodzera.
Kugadzirira PAC nePAM Solutions
Kugadzirira mishonga nemazvo kwakakosha kuti mushonga upihwe zvakanaka.
* Kugadzirira mhinduro yePAC
PAC inowanzo gadzirwa semushonga we5–10%.
PAC inonyungudika nekukurumidza uye inogona kushandiswa mukati mezuva rimwe chete.
*Kugadzirira mhinduro yePAM
PAM inoda kugadzirira kwakanyatsonaka.
Kutarisa kwakajairika:
Mhinduro ye 0.05–0.1%
Kugadzirira muenzaniso:
- Wedzera mvura mutangi rekusanganisa
- Fukidza upfu hwePAM zvishoma nezvishoma
- Kurunga zvinyoro nyoro kwemaminitsi 30–60
- Rega kuchembera kwemaminitsi makumi matatu
Zvinyorwa zvakakosha:
- Dzivisa kusanganisa nekukurumidza (kunogona kutyora cheni dzepolymer)
- Shandisa mvura yakachena
- Gadzirira mushonga mutsva zuva nezuva
Kusanganisa Mamiriro Ekubatsira Kubatanidza Mazino
Kusanganisa simba kunokanganisa zvikuru mashandiro ekugwamba kweropa.
Danho rekusanganisa nekukurumidza
Chinangwa: kuparadzira PAC nekukurumidza.
Zvakajairika maparamita:
- Nguva: masekondi 30–60
- Kumhanya kwegiredhi (G): 700–1000 s⁻¹
Danho reFlocculation
Chinangwa: bvumira maruva kukura asingatyoke.
Zvakajairika maparamita:
- Nguva: maminetsi gumi nemashanu kusvika makumi matatu
- Kumhanya kwemuchadenga: 20–80 s⁻¹
PAM inowanzowedzerwa pakutanga kwechikamu chekudonha kwemasero.
Kuedzwa kweJar kuti Kugadzirise Maitiro
Kuedza jar ndiyo nzira yakavimbika yekuona musanganiswa wePAC nePAM wakakodzera.
Maitiro ekuyedza chirongo chejar akajairwa
- Gadzirira mienzaniso yakawanda yemvura
- Wedzera madosi akasiyana ePAC
- Musanganiswa unokurumidza
- Wedzera PAM
- Musanganiswa unononoka
- Tarisa kuumbwa kwefloc
- Yera kutenderera mushure mekudzikama
Zvakakosha:
- Saizi yeFloc
- Kumhanya kwekugadzirisa
- Kuchena kwemvura
Chiyero chakanaka chinoburitsa:
- Mafuro makuru
- Kugadzikana nekukurumidza
- Mvura yakachena isina simba
Zvikanganiso Zvakajairika Pakubatanidza PAC nePAM
Kunyangwe vashandi vane ruzivo rwakakura dzimwe nguva vanosangana nematambudziko.
Mhedziso
Kusanganisa Polyaluminum Chloride nePolyacrylamide ndeimwe yenzira dzinoshanda zvikuru dzekuvandudza kuvharika kwemvura uye kutenderera kwemvura mumasisitimu ekurapa mvura.
PAC inokanganisika zvidimbu zvakasungirirwa kuburikidza nekudzora simba remagetsi, ukuwo PAM ichivandudza kuumbwa kwefloc kuburikidza nekubatanidza polymer. Kana ikashandiswa nenzira chaiyo—PAC kutanga, PAM yechipiri—makemikari aya anogadzira floc hombe, dzakakora dzinogara nekukurumidza uye dzinoburitsa mvura yakachena.
Kuti vawane mhedzisiro yakanaka, vashandi vanofanirwa kutarisa pane zvinotevera:
- Kurongeka kwedosi kwakakodzera
- Kudzora kwakarurama kwemuyero
- Kugadzirira mhinduro chaiyo
- Mamiriro ekusanganisa akagadziriswa
- Kuyedzwa kwechirongo chekugadzirisa maitiro
Nekushandisa nzira dzakakodzera, PAC nePAM zvinogona kuvandudza zvakanyanya kushanda zvakanaka kwekuchenesa mvura, kushanda kwetsvina, uye kuvimbika kwehurongwa hwese.
