IPolydadMac, i-polydimethyldonilllalammoniamlammoniamlammonium chloride, iyi-polymer enamanzi ye-cationeble esetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi. Ngenxa ye-cationic caticicial chark maject kanye ne-solubility ephezulu ye-solubility, i-polydadmac iyisivumelwano esisebenzayo esingasusa ngempumelelo i-tubidity, umbala kanye nokunye ukungcola kwamanzi. Kodwa-ke, kuzinhlelo zokusebenza ezisebenzayo, kuvame ukusetshenziswa njengei-flecculontantNgokuhambisana nezinye ama-coagulants ukwelapha indle yezimboni.
Izici kanye Mechanism of Action of PolydadMac
Ama-polydadmac asheshe ama-adederates ahlanganise izinhlayiya ze-colloidal ezikhokhiswa kabi futhi amiswe ama-solids emanzini ngenxa yokushaja kwayo okuphezulu kwe-cationic. Indlela yalo yesenzo isuka ikakhulu ekuheheni ngogesi, okubangela lezi zinhlayiya ezincane ukuba zibe nokugibela izinhlayiya ezinkulu, ukuze zisuswe ngempumelelo ngezindlela ezalandela zezulu noma izinqubo zokuhlunga.
I-Floccation Mechanism of PolydadMac
I-Floccation ingenye yezinyathelo ezisezinhlelweni zokuhlangana. Kubhekisa kwinqubo lapho
"Izimbali ezincane ze-alum" ezakhiwe ngesikhathi senqubo yokugibela ifomu lezinhlayiya ezinkulu nge-adsorption, ukungathathi hlangothi kukagesi, ukubopha kanye nokuthwebula inetha.
Embonini yelashwa yamanzi, ama-adsorption kanye nokungathathi hlangothi kukagesi kungama-classfied njengokuhlanganiswa, ngenkathi ukubopha kanye nokuthwebula kwenetha kumiswa njengokufutheka. Amakhemikhali ahambisanayo abizwa ngokuthi ama-coagulants kanye ne-flocculants ngokulandelana.
Ngokuvamile kuzwakala ukuthi i-polydadmac inezindlela ezintathu zesenzo: ama-adsorption, ukungathathi hlangothi kukagesi nokubopha. Ababili bokuqala bangabaphambili. Kungakho i-polydadmac ihlukaniswa njengama-coabulants. Kodwa-ke, iningi labantu libheka ukubheja kanye nokufakelwa njengenqubo efanayo, ngakho-ke uPolydadMac ubizelwe nangokuthi i-flocculant.
Ezinhlelweni zokwelashwa kwamanzi, i-polydadmac isetshenziswa ikakhulukazi njenge-flocculant ukwenza ngcono ikhwalithi yamanzi. Ngokukhethekile, i-amonical quaternary anmonium usawoti iqembu le-polydadMac lingakhiqiza ukuheha ama-elektrostic noma izinhlayiya ezisomisiwe emanzini, okuholela ekungathathi hlangothi, kwakha ama-flocs anezinhlayiya ezinkulu futhi uzixalele. Lawa ama-flocs aqokiwe ngesikhathi sokuqanjwa kabusha okulandelayo noma inqubo yokuhlunga ukuze ahlanze ikhwalithi yamanzi.
Izinzuzo zePolydadMac
Uma kuqhathaniswa ne-Flocculants yendabuko (Alum, PAC, njll.), I-PolydadMac inezinzuzo ezibalulekile ezilandelayo:
Esebenzayo: IPolydadMac ingasusa ukungcola ngokushesha emanzini futhi ithuthukise ikhwalithi yamanzi.
Kulula ukusebenza kahle: Ukusetshenziswa kwayo kulula, vele ungeze ngaphansi kwezimo ezifanele.
Ukusimama: IPolydadMac inokuqina okuhle futhi ayidiliki kalula njenge-polylamide.
Umphumela we-Floccation onamandla
Ukumelana nosawoti okuhle, ukumelana nosawoti kanye ne-Alkali
Izindleko eziphansi: I-PolydadMac inokusebenza kahle okuphezulu kwe-floccation kanye nomthamo ophansi, onganciphisa izindleko zokwelashwa kwamanzi.
I-Sludge ephansi: IPolydadmac ikhiqiza i-sludge engaphansi kune-inorganic coagulants kanye ne-flocculants bese ugcine izindleko zokusebenza ngemuva.
Umthamo wePolydadmac nezindlela zokuphepha
Lapho usebenzisa i-PolydadMac, izinqubo zokusebenza kufanele zilandelwe ngokuqinile ukuze ziqinisekise imiphumela yokwelashwa efanele futhi igweme imiphumela emibi engenzeka. Imvamisa, ngemuva kokungeza ama-flocculants anjenge-polyaluminium chloride, i-polydadmac ingezwe ukufeza umphumela omuhle kakhulu wokuhlangana. Ngaphezu kwalokho, umthamo kufanele ulungiswe ngokufanele ngokwekhwalithi yamanzi kanye nezidingo zokwelashwa. Umthamo ofanelekile anganqunywa ukuhlolwa kwe-jar.
Sekukonke,I-PolydadMacIdlala indima ebalulekile emkhakheni wokwelashwa kwamanzi. Ukuqonda okujulile kwezakhiwo zayo nezinhlelo zokusebenza kuzosiza ekusebenziseni kahle lo mkhiqizo ukuthuthukisa ikhwalithi yamanzi futhi kuvikeleke imvelo.
