Kurapa Mvura Yakasviba Mumaindasitiri – Flocculants (PAM)

Mumvura yakasviba yemumaindasitiri, dzimwe nguva pane tsvina inoita kuti mvura ive nefuru, izvo zvinoita kuti mvura iyi iome kuchenesa. Zvakakosha kushandisa flocculant kuti mvura ibude yakachena kuti isvike padanho rekubuditsa mvura. Kune flocculant iyi, tinokurudzirapolyacrylamide (PAM).

Flocculantyekurapa mvura yakasviba mumaindasitiri

Polyacrylamide ipolymer inonyungudika mumvura. Cheni yayo yemamorekuru ine mapoka epolar, ayo anogona kunyudza zvidimbu zvakasungirirwa mumushonga uye kuunganidza zvidimbu kuti zvigadzire zvidimbu zvakakura. Maflocs makuru akagadzirwa anogona kukurumidzisa kunaya kwezvikamu zvakasungirirwa uye kukurumidzisa mhedzisiro yekujekesa kwemushonga. Kana tichienzanisa nekurapa kwemvura yakasviba, kurapwa kwemvura yakasviba nemakemikari kwakaoma zvikuru. Mukurapa mvura yakasviba nemakemikari, zvinhu zvakasiyana-siyana zvakaita seflocculants, coagulants, uye decolorizers zvinodiwa. Pakati pazvo, flocculant inowanzoshandiswa i nonionic polyacrylamide.

Kubudirira kwe polyacrylamide

1. Cheni yemamorekuru epolyacrylamide ine mapoka epolar, anogona kunwisa zvidimbu zvakasungirirwa mumvura uye kusanganisa zvidimbu kuti zvigadzire maflocs makuru.

2. Polyacrylamide isiri ionic inogona kukurumidzisa kunaya kwezvimedu zvakasungirirwa nekugadzira maflocs makuru, nokudaro ichikurumidzisa kujeka kwemushonga uye kukurudzira mhedzisiro yekusefa.

3. Pakati pezvinhu zvese zvinogadzirwa neflocculant, non-ionic polyacrylamide ine simba rakanaka pakurapa mvura yakasviba ine acidic, uye makemikari marara anowanzova acidic. Saka, non-ionic polyacrylamide ine zvayakanakira zvakasiyana mukurapwa kwemvura yakasviba nemakemikari.

4. Iyo coagulant inogona kushandiswa pamwe chete ne inorganic salts dzakadai se polyaluminum, polyiron nedzimwe inorganic flocculants, uye mhedzisiro yacho iri nani. Imhaka yehunhu hwe non-ionic polyacrylamide ndiyo inoita kuti ive nezvakanaka pachena mukurapa mvura yakasviba yemakemikari.

Tinopa PAM yepamusoro-soro yekutenga zvinhu zvakagadzirwa nefekitori, kuitira kuti muwane PAM isingadhuri uye muwane ruzivo runogutsa mushure mekutengesa.
