Lub tshuab dewatering ntawm sludge feem ntau yog tshem tawm cov dej capillary ntawm cov sludge hais.
Cov neeg kho tshuab lub cev qhuav dej ntawm sludge tshuab ziab khaub ncaws feem ntau suav nrog siv lim xovxwm, phaj thiab ncej lim xovxwm thiab decanter centrifuge. Thaum cov sludge tau pov tseg, sludge lub cev qhuav dej tuaj yeem txo qhov chaw sib xyaw ntawm cov sludge thiab txuag qhov tshwm sim ntawm sludge thaum thauj. tus nqi ntawm. Thaum cov sludge yog composted, sludge dewatering tuaj yeem ua kom muaj kev vam meej ntawm kev sib xyaw ua ke (cov sludge feem ntau yuav tsum muaj dej ceev ceev thaum lub sij hawm composting); Yog hais tias cov sludge yog incinerated, lub siab sludge dewatering tus nqi yuav txo tau lub tshav kub zog noj.
Nyob rau hauv tus txheej txheem ntawm kev siv, cov downstream drying txoj kev yog tsuas yog siv. Cov khoom ntub dej hauv cov khoom siv thiab cov roj flue nkag mus rau hauv cov cuab yeej ntawm tib sab, kom lub tshuab ziab khaub ncaws tuaj yeem siv tau nws qhov kub kub flue roj kom tau txais cov evaporation siab. Qhov kub ntawm qhov hluav taws xob qis dua, qhov thermal efficiency ntau dua.
Txawm li cas los xij, cov sludge muaj pes tsawg leeg yog complex, cov txheeb ze ntom yog me me, cov hais yog zoo, thiab cov sludge feem ntau nyob rau hauv ib tug colloidal lub xeev, uas txiav txim seb tus yam ntxwv ntawm nws tsis yooj yim lub cev qhuav dej. .
