Factors cuam tshuam rau Coagulation nyhuv ntawm cov ua kua Aluminium Sulfate

Factors cuam tshuam rau cov paib ntxhib ntawm cov kua tshuaj kua tshuaj sulfate

Ua kua dej cum sulfate nyob rau hauv ib yam mob twg yuav ua tau coagulation, yam ntawm nws coagulation nyhuv ntawm yam dab tsi? Ua tibzoo saib nws

Nws feem ntau ntseeg tias yam uas cuam tshuam rau cov coagulation ntawm kua txhuas sulfate yog dej kub, tshem tawm cov txheej txheem concentration hauv dej, tus nqi pH, coagulant dos thiab thiaj li. Dej kub tsis dhau, Colloidal Brownian zog ua kom qeeb, dej hlob, coagulant hydrolysis qeeb, yog li qhov dej kub yog feem ntau 20 ~ 30 ℃ tsim nyog. Cov kev sim rau cov dej kub ntawm 25 ~ 30 ℃, nyob rau hauv cov kab mob nrog rau qhov uas yuav tsum tau muaj qhov kub tshaj plaws. Thaum lub ntsiab lus ntawm cov khoom ntim qis hauv cov dej tsis tshua muaj, qhov sib tsoo ntawm qhov sib tsoo feem ntau raug txo, cov nyhuv coagulation tsis zoo; tab sis qhov concentration siab, qhov uas yuav tsum tau coagulation koob nce siab. Tus nqi pH cuam tshuam txog kev kuaj pom thiab qhov chaw ntawm cov pa paug, tiam sis kuj cuam tshuam rau lub zog ntsuas ntawm coagulants thiab lub cev thiab lub sij hawm ntawm cov khoom hauv lub neej. Leachate muaj ib cov degree siab ntawm bicarbonate alkalinity, cov pH muaj ib txhia tsis nyhuv.

Qhov tshwm sim qhia tau hais tias lub weakly alkaline leachate yuav ua tau zoo dua cov kev sim tsis muaj cov kua qaub thiab cov kab mob hauv alkali. Kev siv tshuaj rau txhuas yam kua qaub sulphate muaj feem xyuam rau hom thiab cov concentration ntawm microparticles hauv dej, thiab tseem muaj feem xyuam rau ntau hom kua txhuas sulphate, qhov kev siv tshuaj thiab qhov nruab nrab.

Ntawm no, kuv ntseeg tias peb muaj ib cov kua txhuas kua tshuaj sulfate muaj kev nkag siab ntawm qhov bar
