Sludge dewatering feem ntau ua tau siv cov hauv qab no filtration presses: siv xovxwm, ncej presses, thiab membrane presses (Bień and Wystalska, 2011).
Txoj kev twg yog siv rau sludge dewatering?
Muaj ntau yam thev naus laus zis rau kev siv tshuab sludge dewatering: nqus pom dewatering, siab pom dewatering, centrifugal dewatering, ntsia hlau xovxwm dewatering. Cov cuab yeej muaj xws li phaj thiab ncej thiab siv lim xovxwm, centrifuging, thiab geomembranes.
Yuav ua li cas sludge dewatering txheej txheem?
Sludge dewatering feem ntau yog tsom rau txo qhov hnyav thiab ntim ntawm cov sludge kom cov nqi pov tseg - suav nrog kev thauj mus los - khaws cia kom tsawg kawg. Kev tshem tawm dej yog qhov tseem ceeb ntawm kev txo qhov ntim ua ntej sludge pov tseg tuaj yeem kho lossis pov tseg ntawm qhov kev lag luam tshaj plaws.
Yuav ua li cas hauv qab no yog siv rau stabilization ntawm sludge?
Kev piav qhia: Cov sludge yog stabilized los ntawm anaerobic digestion. Txiv qaub txias thiab aerobic digestion yog lwm txoj hauv kev thiaj li ua kom muaj kev ruaj khov. Cov sludge tau stabilized ua ntej nws yuav raug txias.
Yuav siv txoj kev twg los kho sludge?
Ntau cov sludges raug kho siv ntau hom kev zom zaub mov, lub hom phiaj ntawm kev txo qis cov organic teeb meem thiab pes tsawg tus. Cov kab mob ua rau cov kab mob muaj nyob hauv cov khib nyiab. Cov kev kho mob feem ntau suav nrog kev zom zaub mov anaerobic, aerobic digestion, thiab composting.

Cov khoom xyaw twg hauv qab no ua cov tshuaj tsw qab hauv cov tshuaj txhuam hniav?
Sodium lauryl sulfate (SLS) yog surfactant feem ntau siv. YPuas yog tshuaj txhuam hniav puas yog surfactant? Surfactants. Ntau, txawm tias tsis yog tag nrho, tshuaj txhuam hniav muaj sodium lauryl sulfate (SLS) lossis lwm yam surfactants (detergents).
Vim li cas thiaj tsim nyog dewatering sludge?
Vim li cas thiaj yuav tsum tau dewatering? Ob lub hom phiaj tseem ceeb ntawm sludge dewatering yog rau pov tseg kom tsawg thiab ua tiav tag nrho cov nqi kev pov tseg. Tsis tas li ntawd, cov sludge ruaj khov tuaj yeem ua haujlwm tau zoo dua thiab tuaj yeem txo qis kev noj qab haus huv.
Dab tsi ntawm cov hauv qab no yuav tsum yog qhov kev xav ntawm txoj kev kos npe rov qab?
Yuav tsum tsis txhob muaj kev nkag tebchaws mus lossis kev tsiv teb tsaws chaw tawm ntawm cov pejxeem. Yuav tsum tsis muaj kev tuag ntawm lub cim thiab lub sijhawm rov qab los. Kev paub txog kev cim yuav tsum tsis txhob ua rau ib tus neeg ntau dua lossis tsawg dua yuav rov qab tau.
Rau cov neeg siv khoom siv dab tsi yog lub hauv paus ntawm kev ua yog?
Utilitarianism tuav tseg tias qhov kev ua yog yog nws nyiam txhawb kev zoo siab thiab tsis ncaj ncees yog tias nws nyiam ua rau muaj kev tu siab, lossis kev rov qab ntawm kev zoo siab-tsis yog kev zoo siab ntawm tus neeg ua yeeb yam tab sis ntawm txhua tus neeg cuam tshuam los ntawm nws.
Dab tsi ntawm cov hauv qab no yog siv rau hauv cov thermite vuam?
In thermite welding, aluminium hmoov yog siv nrog rau ferric oxide. Aluminium muaj ntau affinity ntawm oxygen thiab nws txo cov ferric oxide rau elemental hlau thaum vuam thiab kuj ua rau kub heev. Lub molten elemental hlau yog li tsim yuav kaw qhov tawg kom muaj kev sib raug zoo.
