Dab tsi yog Dej Kub Rau Kev Siv Hlau Tsis Muaj Aluminium Sulfate

Nyob rau sab qaum teb ntawm lub caij ntuj no, koj tuaj yeem xaiv ntxiv cov hlau tsis muaj txhuas sulfate nyob ib ncig ntawm 10 teev sawv ntxov lossis 3 teev tsaus ntuj, thaum kub siab dua.
Tab sis thaum qhov kub thiab txias dhau lawm, PAC hydrolyzes sai sai thiab reacts sai heev nrog cov pa phem hauv dej, tsim me me thiab hydrated flocs uas ua rau kom cov dej noo ntawm cov sludge thiab nce tus nqi ntawm sludge kho. Cov hlau tsis muaj txhuas sulfate kuj tseem tuaj yeem ua rau tsis muaj zog ntawm qhov kub thiab txias, thiab nws cov nyhuv polymer flocculation tsis tuaj yeem tawm dag zog. Yog li, thaum siv txhuas sulfate, cov dej kub tuaj yeem tswj tau siab tshaj 5 degree, nyiam dua ntawm 20 degree thiab 50 degree. Qhov ntawd yog, nyob rau hauv qhov kub thiab txias tas li, qhov kub thiab txias dua, qhov kev sib zog ntau dua ntawm Brownian cov lus tsa suab thiab qhov ceev ntawm cov tshuaj tiv thaiv.
Yog li ntawd, thaum siv hlau tsis muaj txhuas sulfate, peb yuav tsum tswj qhov kub kom zoo thiab tsis txhob siab dhau los yog qis dhau, txwv tsis pub nws yuav cuam tshuam rau nws cov txiaj ntsig.
