Ua ntej txhua yam, vim hais tias cov ntaub ntawv ntawm lub tshuab ob lub ntsej muag sludge tshuab ziab yog txhua cov ntaub ntawv hlau, kev ua haujlwm ntawm cov khoom siv hlau yog qhov siab heev. Nyob rau hauv ib txwm muaj xwm txheej, lub sludge tshuab ziab khaub ncaws ua haujlwm hauv qhib cua. Thaum lub sij hawm dewatering thiab ziab ntawm lub sludge, lub sij hawm ntev raug rau huab cua noo yuav ua rau cov khoom siv hlau thaum muaj cov tshuaj tiv thaiv oxidation thiab thaum kawg ua rau xeb.
Qhov thib ob, yog tias qhov zoo li ntawm sab hauv sab hauv ntawm lub duav sludge tshuab zwm yog cov nyom ntau dua thiab lub ntsej muag rougher, ces nws qhov kev txhim kho corrosion yuav ntau dua. Thaum cov khoom sab hauv tau hloov kho, cov hlau nyob rau hauv kev sib cuag nrog cov feem yuav tseem corrode, thiab qhov nrawm nrawm heev.
Thaum kawg, vim tias qhov khoom ntawm lub tshuab nqus sludge yog sludge, cov khoom siv no tsis tsuas yog muaj cov dej noo ntau tshwj xeeb, tab sis kuj muaj ntau cov khoom sib xyaw hauv cov sludge, uas yog cov pov tseg tsis muaj cov tshuaj tiv thaiv corrosive. Hauv cov txheej txheem ntawm sludge dewatering thiab ziab, thaum qhov kub ntawm cov cuab yeej kom qhuav nce, los yog muaj cov pa oxygen thiab chloride ntau nyob hauv ib puag ncig, nws yooj yim rau cov tshuaj lom neeg nrog lub ntsej muag sib tshiav kom tshuab thiab ua kom cov xeb ntawm ob -shaft hniav tshuab. degree.
