Daim ntawv thov ntawm cov xovxwm lim hauv kev lag luam kub-dip galvanizing hauv Nyab Laj

Cov ntaub ntawv tseem ceeb:Lub tuam txhab ua 20000 tons ntawm cov galvanizing kub txhua xyoo, thiab cov dej khib nyiab tsim tawm feem ntau yog cov dej khib nyiab yaug. Tom qab kho, qhov ntau ntawm cov dej khib nyiab nkag mus rau hauv chaw kho dej khib nyiab yog 1115 cubic meters ib xyoos. Xam raws li 300 hnub ua haujlwm, qhov ntau ntawm cov dej khib nyiab tsim tawm yog li 3.7 cubic meters ib hnub.

Cov txheej txheem kho mob:Tom qab sau cov dej khib nyiab, cov kua alkaline ntxiv rau hauv lub tank tswj kev ua kom tsis muaj zog kom kho qhov pH rau 6.5-8. Cov khoom sib xyaw ua ke thiab homogenized los ntawm kev sib xyaw pneumatic, thiab qee cov ferrous ions raug oxidized rau cov hlau ions; Tom qab sedimentation, cov dej khib nyiab ntws mus rau hauv lub tank oxidation rau aeration thiab oxidation, hloov cov ferrous ions tsis tau tshem tawm mus rau hauv cov hlau ions thiab tshem tawm qhov tshwm sim ntawm yellowing hauv cov effluent; Tom qab sedimentation, cov effluent ntws mus rau hauv lub tank dej rov siv dua, thiab tus nqi pH raug kho rau 6-9 los ntawm kev ntxiv acid. Kwv yees li 30% ntawm cov dej huv rov siv dua hauv qhov chaw yaug, thiab cov dej huv seem ua tau raws li tus qauv thiab txuas nrog lub network dej phwj hauv tsev hauv thaj chaw Hoobkas. Cov sludge los ntawm lub tank sedimentation raug kho raws li cov khib nyiab khoom phom sij tom qab dewatering, thiab cov filtrate raug xa rov qab mus rau lub kaw lus kho.

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

Kev ntsuas kev siv tshuab:Cov khoom siv tswj tus kheej pH tau teeb tsa rau txhua qhov chaw uas muaj kev tswj tus nqi pH, ua rau nws yooj yim rau kev khiav lag luam thiab txuag cov tshuaj. Tom qab kev hloov pauv txheej txheem tiav lawm, kev tso tawm cov dej khib nyiab ncaj qha tau txo qis, thiab kev tso tawm cov pa phem xws li COD thiab SS tau txo qis. Qhov zoo ntawm cov dej khib nyiab tau mus txog qib peb ntawm Cov Txheej Txheem Kev Tso Tawm Dej Khib Nyhiab (GB8978-1996), thiab tag nrho cov zinc tau mus txog qib thawj.
