Thermal drying method thiab kev khiav hauj lwm tus nqi ntawm sludge feem ntau yog siab, yog li cov kev tsim kho yuav tsum tau thiab tej yam kev mob rau thermal sludge drying kuj siab, thiab cov cheeb tsam uas yuav nrov thiab thov yog txwv. Yuav kom txo tau tus nqi ntawm kev sib sib zog nqus dewatering, feem ntau ntawm lawv yog sib sib zog nqus dewatering los ntawm cov tshuaj txias ua ke nrog phaj thiab ncej lim xovxwm tshuab. Nws tag nrho cov nqi khiav lag luam yog qis dua li cov thev naus laus zis thev naus laus zis, tab sis kuj tseem muaj ntau yam teeb meem. Nyob rau hauv cov nqe lus ntawm cov cua txias siv, feem ntau ntawm cov conditioning agents siv yog ferric chloride, quicklime, ya tshauv, thiab lwm yam.
Los ntawm kev xav txog cov txheej txheem pov tseg, los ntawm kev ntxiv cov tshuaj ntsev thiab cov kua qaub, tom qab nkag mus rau hauv qhov chaw pov tseg, cov kua qaub uas muaj cov tshuaj chloride ions thiab COD siab yuav muaj kev cuam tshuam loj rau ntawm qhov chaw pov tseg.
Yog tias kev kho mob incineration tau ua tiav, vim yog qhov sib ntxiv ntawm ntau cov tshuaj inorganic, tus nqi calorific yuav txo qis thiab cov hmoov tshauv yuav nce ntxiv. Tshwj xeeb tshaj yog tom qab ntxiv alkaline tshuaj xws li quicklime, nws yuav ua rau corrosion thiab scaling ntawm lub cub tawg, thiab nws yog ib qho nyuaj rau ua tau raws li qhov yuav tsum tau ntawm incineration. . Txoj kev kho tshuaj lom neeg tsis tau ua tiav qhov txo qis ntawm cov sludge vim yog xaiv cov tshuaj txias txias, thiab tau ua rau muaj kev cuam tshuam tsis zoo ntawm kev pov tseg tom qab.
