Nyob rau hauv lub tshuab ziab khaub ncaws, cov sludge kho tau ntog rau ntawm lub tshuab ziab khaub ncaws sai sai, thiab cov khoom siv loj-rotating huab yog tsim nyob rau hauv lub ziab chamber. Cov pa hluav taws xob kub los ntawm kev sib xyaw ua ke ntawm cov cua sov thiab lub zog, cov pa roj combustion chamber los yog kev sib txuas ntawm ob lub zog hluav taws xob yog xa mus rau lub tshuab ziab khaub ncaws hauv cov yeeb nkab.
Dawb thiab yooj yim phiv yog tsim los ntawm kev cuam tshuam ntawm huab cua kub. Thaum lub sij hawm ziab, biomass / dej phwj sludge thiab evaporated dej yog kom huv si ntxuav. Cov dej phwj tuaj sludge dhau los ntawm txhua lub chamber nyob rau hauv ib qho kev tswj thiab tag nrho automated yam. Lub degree ntawm dryness tuaj yeem hloov kho ntawm 80% thiab 95% qhuav qhuav raws li cov neeg siv khoom xav tau. Kev ua haujlwm siab txhais tau hais tias lub sijhawm nyob nruab nrab ntawm lub tshuab ziab khaub ncaws tsawg dua 5 feeb. Cov pa tso pa yog ua tiav hauv lub tshuab ziab khaub ncaws kaw. Vim muaj huab cua kub, ammonia nyob rau hauv cov dej phwj tuaj sludge raug tshem tawm tam sim ntawd. Tsis tas yuav tsum tau tshem tawm cov dej ntws los yog lwm yam pa purification.
Tag nrho cov pa roj ntws los ntawm kev sib xyaw ua ke zoo lim, yog li yuav luag tag nrho cov plua plav tawm. Yog tias muaj ntxhiab tsw ntxhiab hauv cov pa tawm, nws tuaj yeem ua tiav oxidized los ntawm cov lim roj ntsha. Lub granulation yog nqa tawm tam sim tom qab granulation. Cov sludge qhuav tsim cov khoom tsis muaj plua plav. Cov pellets loj heev tuaj yeem khaws cia rau hauv cov thawv qhib thiab thauj khoom siv cov khoom thauj khoom loj. Cov dej phwj tuaj sludge yog ces haum rau phosphorus rov qab thiab gasification, combustion los yog siv raws li kis tau chiv.
