Ukuze kukhutshwe okanye kusetyenziswe kwakhona i-Sewage emva koNyango, kufuneka kusetyenziswe iintlobo ngeentlobo zeekhemikhali kwinkqubo yoNyango lwe-Sewage. Namhlanje,Ababoneleli ngePAM (Polyacrylamide)ndiza kukuxelela ngee-flocculants:
I-Flocculant: Ngamanye amaxesha ikwabizwa ngokuba yi-coagulant, ingasetyenziswa njengendlela yokuqinisa ukwahlukana kolwelo oluqinileyo, kwaye ingasetyenziswa kwi-primary setting tank, secondary setting tank, flotation tank, tertiary treatment okanye advanced treatment kunye nezinye ii-process links.
Ii-Flocculants zisetyenziswa njengendlela yokuqinisa ukwahlulwahlulwa kolwelo oluqinileyo kwicandelo lokunyanga amdaka. Zingasetyenziselwa ukuqinisa ukutsalwa kwenkunkuma yamanzi amdaka, unyango lokudada kunye nokutsalwa kwenkunkuma okwesibini emva kwenkqubo yokutsalwa kwenkunkuma esebenzayo, kwaye zingasetyenziselwa unyango oluphezulu okanye unyango oluphambili lwamanzi amdaka. Xa zisetyenziselwa ukulungisa ngaphambi kokuba amanzi amdaka agqithisileyo aphele, ii-flocculants kunye nee-coagulants ziba zii-sludge conditioners okanye ii-dehydrating agents.
Xa usebenzisa ii-flocculants zemveli, indlela yokongeza izixhobo zokuncedisa ukuxinana ingasetyenziselwa ukuphucula isiphumo se-flocculation. Umzekelo, ukusebenzisa i-activated silicic acid njengesixhobo sokuncedisa ukuxinana kwii-flocculants ezingaphiliyo ezifana ne-ferrous sulfate kunye ne-aluminium sulfate kunye nokuzongeza ngokulandelelana kunokufezekisa ukuxinana okuhle. Ke ngoko, ngokwemigaqo yabantu abaqhelekileyo, i-inorganic polymer flocculant IPF ilungiswa ngokudibanisa isixhobo sokuncedisa ukuxinana kunye ne-flocculant ize yongezwe kunye ukuze kube lula ukusebenza komsebenzisi.
Unyango lokuxinana ludla ngokubekwa phambi kwesakhiwo sokwahlukanisa ulwelo oluqinileyo, kwaye xa ludityaniswe nesakhiwo sokwahlukanisa, lunokususa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo kunye nezinto ze-colloidal ezinobukhulu besuntswana obuyi-1nm ukuya kwi-100μm emanzini aluhlaza, lunciphise ukungcoliseka kwamanzi amdaka kunye ne-CODCr, kwaye lungasetyenziswa kunyango lwangaphambi kwenkqubo yonyango lwamanzi amdaka. Unyango, unyango oluphambili, lunokusetyenziswa kunyango lwenkunkuma eseleyo. Unyango lokuxinana lunokususa ngokufanelekileyo iintsholongwane kunye neebhaktheriya ezibangela izifo emanzini, kwaye lususe ioyile exutyiweyo, i-chroma, ii-ion zesinyithi esinzima kunye nezinye izinto ezingcolisayo emanzini amdaka. Izinga lokususwa kwe-phosphorus equlethwe emanzini amdaka linokuba phezulu ukuya kwi-90% xa ukuxinana kwenkunkuma kusetyenziswa ukunyanga i-phosphorus. ~95%, yeyona ndlela ingabizi kakhulu nesebenzayo yokususa i-phosphorus.
Kwinkqubo yokucoca amanzi amdaka, kuza kusetyenziswa ezinye izinto ezisetyenziswayo. Namhlanje,Umenzi wePAMbazise enye kuphela kuzo. Ngaba usayiqonda? Nika ingqalelo kwiYuncang kwaye uphendule ulwazi oluthe kratya malunga nokucocwa kwamanzi amdaka kuwe!
