Industrial Wastewater Treatment – ​​Flocculants (PAM)

Mumvura yetsvina yemumaindasitiri, pane dzimwe nguva muine tsvina inoita kuti mvura iite makore, izvo zvinoita kuti tsvina iyi iome kuchenesa.Izvo zvinodikanwa kushandisa flocculant kuita kuti mvura ijekese kuti isangane nechiyero chekubuda.Kune iyi flocculant, tinokurudzirapolyacrylamide (PAM).

Flocculantyekugadzirwa kwemvura yakasviba mumaindasitiri

Polyacrylamide i polymer inonyungudika mumvura.Cheni yaro yemamorekuru ine mapoka epolar, anogona kushambadza zvimedu zvakamiswa mumhinduro uye kuunganidza zvimedu kuti zvigadzire maflocs makuru.Iwo maflocs makuru akaumbwa anogona kukurumidza kunaya kwezvimedu zvakamiswa uye nekumhanyisa mhedzisiro yekujekesa mhinduro.Kuenzaniswa neyakajairwa tsvina yemvura, kurapwa kwemakemikari tsvina kwakaoma.Mukuita kurapa makemikari tsvina yemvura, maajenti akasiyana senge flocculants, coagulants, uye decolorizers anodiwa.Pakati pavo, iyo inowanzoshandiswa flocculant is nonionic polyacrylamide.

Iyo yekuvandudza maitiro e polyacrylamide

1. Iyo polyacrylamide molecular cheni ine mapoka epolar, anogona kutora zvimedu zvakaturikwa mumvura uye zambuko pakati pezvimedu kuita flocs hombe.

2. Non-ionic polyacrylamide inogona kukurumidzira kunaya kwezvimedu zvakaturikwa nekugadzira flocs yakakura, nekudaro ichimhanyisa kujekeswa kwemhinduro uye nekusimudzira iyo filtration effect.

3. Pakati pezvigadzirwa zvese zvinoyerera, isiri-ionic polyacrylamide ine mhedzisiro yakanaka pakurapa acidic tsvina, uye makemikari tsvina inowanzoita acidic.Naizvozvo, isiri-ionic polyacrylamide ine yakasarudzika mabhenefiti mukatichemikari tsvina kurapwa.

4. Iyo coagulant inogona kushandiswa pamwe chete neinorganic munyu senge polyaluminium, polyiron uye mamwe inorganic flocculants, uye mhedzisiro yacho iri nani.Izvo chaizvo nekuda kwehunhu hweiyo isiri-ionic polyacrylamide iyo ine mabhenefiti ari pachena mukurapa kwemakemikari tsvina.

Isu tinopa PAM yepamusoro-soro yekutanga-ruoko rwekugovera fekitari, kuitira kuti iwe uwane mari inodhura PAM uye inogutsa mushure mekutengesa ruzivo.
