Daim ntawv thov lim xovxwm nyob rau hauv ib tug kub-dip galvanizing enterprise nyob rau hauv Nyab Laj

Cov ntaub ntawv tseem ceeb:Lub lag luam txheej txheem 20000 tons ntawm kub-dip galvanizing ib xyoos ib zaug, thiab cov dej khib nyiab ntau lawm yog tsuas yog yaug cov dej khib nyiab. Tom qab kev kho mob, tus nqi ntawm cov dej khib nyiab nkag mus rau qhov chaw kho dej khib nyiab yog 1115 cubic meters ib xyoos twg. Muab xam raws li 300 hnub ua haujlwm, tus nqi ntawm cov dej khib nyiab tsim tawm yog li 3.7 cubic meters ib hnub twg.

Txoj kev kho mob:Tom qab sau cov dej khib nyiab, cov tshuaj alkaline ntxiv rau hauv qhov nruab nrab tswj lub tank kom kho tus nqi pH rau 6.5-8. Cov sib tov yog homogenized thiab homogenized los ntawm pneumatic stirring, thiab ib co ferrous ions yog oxidized rau hlau ions; Tom qab sedimentation, cov dej khib nyiab ntws mus rau hauv lub tank oxidation rau aeration thiab oxidation, converting cov unremoved ferrous ions rau hauv hlau ions thiab tshem tawm qhov tshwm sim ntawm yellowing nyob rau hauv lub effluent; Tom qab sedimentation, cov effluent ntws mus rau hauv lub tank rov qab siv dua, thiab pH tus nqi raug kho rau 6-9 los ntawm kev ntxiv cov kua qaub. Kwv yees li 30% ntawm cov dej huv tau rov qab siv dua hauv cov dej yaug, thiab cov dej huv uas tseem tshuav ua tau raws li tus qauv thiab txuas nrog cov kav dej phwj hauv tsev hauv cheeb tsam. Cov sludge los ntawm cov sedimentation tank raug kho raws li cov khoom pov tseg tsis zoo tom qab dewatering, thiab cov lim dej rov qab mus rau qhov kev kho mob.

Cov khoom siv lim dej: Cov tshuab dewatering ntawm sludge siv cov cuab yeej xws li XMYZ30/630-UBlim xovxwm(tag nrho lub peev xwm ntawm lim chamber yog 450L).

Kev ntsuas automation:pH tswj tus kheej cov cuab yeej tau teeb tsa ntawm txhua qhov chaw uas muaj kev tswj hwm tus nqi pH, ua kom yooj yim rau kev khiav lag luam thiab txuag cov tshuaj noj. Tom qab cov txheej txheem hloov pauv tiav lawm, qhov ncaj qha tawm ntawm cov dej khib nyiab raug txo, thiab cov pa paug xws li COD thiab SS raug txo. Cov dej ntws zoo tau mus txog qib thib peb tus qauv ntawm Cov Txheej Txheem Kev Ua Dej Num Zoo Tshaj Plaws (GB8978-1996), thiab tag nrho cov zinc tau mus txog qib thawj tus qauv.
