I-PolydadMac: Izinto ezibalulekile zeSludge Dewanting

I-Sludge dehydration iyingxenye ebalulekile yenqubo yokwelashwa kwendle. Inhloso yawo ukususa ngempumelelo amanzi e-sludge, ukuze inani le-sludge lincane, futhi izindleko zokulahla nendawo yomhlaba zincishisiwe. Kule nqubo, ukukhethwa kweI-flecculontantukhiye, ne-polydadmac, njengento esebenza kahleI-Cationic Polymer Flocculont, idlala indima ebaluleke kakhulu.

Okokuqala, kudingeka siqonde ukwakheka nezakhiwo ze-sludge. I-Sludge idonswa kahle i-sediment eqinile ekhiqizwa ngesikhathi sokwelashwa kwendle. Inezingxenye eziyinkimbinkimbi ezifana nemfucumfucu ye-organic, amaqembu ama-microbial, izinhlayiyana ze-inorganic nama-colloids. Ama-solids amiswe esitsheni abhekene necala elibi futhi axoshena, kanti amanzi agcwalisa maphakathi nama-solids amisiwe, ngakho-ke okuqukethwe kwamanzi kokuqala kungafinyeleleka ku-95%. Ngakho-ke, ukwenza ngempumelelo i-sludge azokhipha ngempumelelo i-sludge sekuyinkinga ebalulekile emkhakheni wokwelashwa kwendle.

Enqubweni yeSludge Dewanting,Ama-Flocculants for Sludge Dewantingkuyinto ebalulekile enethonya. I-Flocculant ihlanganisa izinhlayiya ezincane e-sludge zibe izinhlayiya ezinkulu ngokusebenzisa ukungathathi hlangothi kukagesi, ukubopha ama-adsortion, njll. Njengomkhiqizo wamakhemikhali osetshenziswa ngokukhethekile ukwelashwa kwamanzi amdaka kanye ne-sludge dehydration, i-polydadmac yenza kahle ekutholeni i-sludge ngenxa yesakhiwo sayo esiyingqayizivele se-molecular futhi ishaja inkazimulo.

Ukwakheka kwamangqamuzana kwePolydadMac kukunikeza ukukhathazeka okukhulu ngobuningi kanye nezakhiwo ezinhle kakhulu ze-adsorption. Ngesikhathi senqubo ye-sludge dehydration, i-polydadmac ingasheshe i-adderb ebusweni bezinhlayiya ze-sludge, inciphise amandla aphikisayo phakathi kokungathathi hlangothi ngogesi, futhi akhuthaze ukwakheka kwama-flocs aphezulu phakathi kwezinhlayiya. Ngasikhathi sinye, amaketanga ama-molecular of polydadmac nawo angakha isakhiwo senethiwekhi ephumelelayo, ukukhipha amanzi amaningi ahlanganiswe phakathi kwezinhlayiya ezingama-sludge, ukuze ivolumu yamanzi lincishiswe libe ngama-60-80% noma liphansi, futhi ivolumu lingancishiswa ngo-75-87%.

Uma kuqhathaniswa ne-Inorganic Flocculants yendabuko, i-polydadmac inesisindo esiphakeme samangqamuzana futhi ishaja inceku, inikeze amandla anamandla okufakelwa. Ngaphezu kwalokho,I-PolydadMacInokusebenza okuhle kakhulu kokuqothula, kulula ukuyisebenzisa, futhi akuvezi ukungcoliswa kwesibili. I-PD ngokwayo ayikhiqizi i-sedimentation efana ne-alum, ngakho-ke inani le-sludge eyengeziwe lingancishiswa.Izinzuzo zenza ama-polydadmac abe namathemba okusebenzisa abanzi emkhakheni we-sludge azokwenza.

Ukwakheka kwamangqamuzana kwePolydadMac kukunikeza ukukhathazeka okukhulu ngobuningi kanye nezakhiwo ezinhle kakhulu ze-adsorption. Amaqembu amaningi we-cationic ku-chain yalo yamangqamuzana angaphendula ngamaqembu e-anionic ebusweni bezinhlayiya ze-sludge ukwakha ama-Ionic Bonds aqinile, okuholela ekutholeni ama-adsorption aqinile. Le adsorption ayizukusiza kuphela ukunciphisa ukuncipha phakathi kwezinhlayiya, kepha futhi kuyasiza ukwakha ama-flocs amakhulu.

Ngokungeziwe esakhiweni samangqamuzana kanye namacala okukhokhisa amaPolydadMac, ukugxila kwawo kanye nemithamo nakho kuyizinto ezibalulekile ezithinta umphumela we-sludge dehydration umphumela. Ngaphakathi kwebanga elithile, njengoba ukugcwala kwePolydadMac kukhuphuka noma ukwanda kwemithamo, ukusebenza okulona isikhathi eside kwe-sludge kungathuthukiswa. Kodwa-ke, ukuphakama kakhulu noma umthamo noma umthamo omkhulu ungaholela emphumeleni ophambene, okuholela ekuvikelweni kwe-colloid, okubuye kunciphise umphumela wokuphelelwa amandla. Ngakho-ke, ezihlolweni ezingokoqobo, ukuhlolwa kanye nokwenza kahle kudingeka kwenziwe ngokuya ngohlelo oluthile lokwelashwa kwendle kanye nezakhiwo ze-sludge ukunquma ukugxilisa i-polydadmac kanye nomthamo.
