Ukupheliswa kwe-sludge yinxalenye ebalulekileyo yenkqubo yonyango lwe-sebage. Injongo yayo kukususa ngokufanelekileyo amanzi kwi-Sludge, ukuze inani le-sludge lincinci, kwaye iindleko zokulahla inkunkuma zincitshisiwe. Kule nkqubo, ukukhethaIflocculantsisitshixo, kunye nePolydadmac, njengento efanelekileyoI-Callic Polymer i-Polyment, udlala indima ebaluleke ngakumbi.
Okokuqala, kufuneka siqonde ubume kunye neepropathi zesalathiso. I-Sludge ikakhulu sediment iveliswe lixesha ngexesha lonyango. Iqulethe izinto ezinzima ezinje nge-orgaric stroric, amaqela entsholongwane, amasuntswana anolwazi kunye neecolloids. Izinyibilikisi ezinqunyanyisiweyo kwi-sludge azihlawuliswa kakubi kwaye ziphindaphinda, ngelixa amanzi egcwalisa i-slids enqunyanyisiweyo, ngoko ke umxholo wokuqala wamanzi unokufikelela kwi-85%. Ke ngoko, indlela yokuphumeza ngokuphumelela kwamanzi e-sludge iye yaba ngumcimbi obalulekileyo kwicandelo lonyango lwethayile.
Kwinkqubo yokupheka ye-sludge,I-Dlocculants ye-Sludge Dewateryinto ebalulekileyo. Idycculant iphazamisa amasuntswana amancinci kwi-Sludge ibe ngamasuntswana amakhulu ngokungathathi cala, ibridbacmation, njl njl. Njengemveliso yekhemikhali esetyenziswa ngokukhethekileyo kunyango lwamanzi amdaka kunye ne-sludge drived, i-polydadmac yenza kakuhle kwi-sludge yokupheliswa kwempahla emzimbeni ngenxa yesakhiwo esikhethekileyo semolekyuli kunye nokuxinana kwemolekyuli eyahlukileyo.
Ubume bemolekyuli yePolydadmac inika ukuxinana okuphezulu kunye nepropathi yezomkhosi. Ngexesha lokuphelelwa ngumzimba, iPolydadmac ikhawuleza ikhawuleze kumphezulu wamasuntswana e-sluds, ukunciphisa amandla aphindaphindiweyo phakathi kwamasuntswana ngethambeka, kunye nokukhuthaza ukwenziwa kweeflocs ezinkulu phakathi kwamasuntswana. Kwangelo xesha, iimolekyuli zePolydadmac zinokwenza isakhiwo esisebenzayo senethiwekhi, sikhutshelwe amanzi amaninzi, kwaye inyibilikiswe amanzi ekulula ukuncitshiswa kwehyding, kunye nevolumu yamanzi okanye iphantsi, kwaye ivolumu incitshiswe yi-75-87%.
Xa kuthelekiswa ne-inorganants yemveli yendabuko, i-polydadmac inesisindo esiphezulu semolekyuli kunye nokuxinana kwe-qued, inika amandla okutya okunamandla. Ukwengeza,I-PolydadmadmacNgaba ukuSebenza okugqithisileyo, kulula ukuyisebenzisa, kwaye akuvelisi ungcoliseko lwesibini. I-PD ngokwayo ayivelisi i-sediement njenge-Alum, ke isixa esongeziweyo sinokuncitshiswa.Ungenelelo Yenza i-polydadmadmadmadmad inamazwe athile asetyenzisiweyo.
Ubume bemolekyuli yePolydadmac inika ukuxinana okuphezulu kunye nepropathi yezomkhosi. Amaqela amaqela amaninzi kwi-molecular thein anokusabela ngamaqela akwa-Anaion kumphezulu wamasuntswana e-sludge ukwenza imingxunya ye-ionic, okukhokelela kwi-adsenption eyomeleleyo. Le adsorption ayincedi nje ukunciphisa ukuziphindezela phakathi kwamasuntswana, kodwa kuyanceda ukwenza iiflocs ezinkulu.
Ukongeza kwimo yemolekyuli kunye neepropathi ze-Polydadmac, uxinzelelo lwayo kunye nedosi ikwanazo nezinto ezibalulekileyo ezichaphazela isiphumo se-sludge. Kuluhlu oluthile, njengoko uxinzelelo lwe-polydadmac lunyukayo okanye umthamo onyukayo, ukusebenza kwamanzi e-Dewaters ye-sludge inokuphuculwa. Nangona kunjalo, uxinzelelo olukhulu kakhulu okanye umthamo unokukhokelela kwisiphumo esichaseneyo, okukhokelela kukhuseleko lweColoid, oluye lunciphisa ifuthe lokuphela kwempahla. Therefore, in practical applications, testing and optimization need to be carried out according to the specific sewage treatment system and sludge properties to determine the optimal PolyDADMAC concentration and dosage.
