Hom Sludge

Hom sludge

Muaj ntau ntau hom sludge, uas tuaj yeem faib raws li lawv lub hauv paus chiv keeb, muaj pes tsawg leeg, thiab lub cev muaj zog. Qee hom sludge muaj xws li

Wastewater sludge yog hais txog cov khoom siv semi-solid uas tau tsim thaum kho cov dej khib nyiab. Nws muaj inorganic thiab organic teeb meem uas tau raug tshem tawm ntawm cov dej khib nyiab thaum lub sij hawm kho, nrog rau tib neeg pov tseg, zaub mov pov tseg, roj, thiab tshuaj. Qhov tseeb muaj pes tsawg leeg ntawm cov dej khib nyiab yog nyob ntawm seb hom dej khib nyiab raug kho, tab sis nws feem ntau muaj cov dej sib xyaw, cov khoom organic, cov as-ham, cov kab mob, thiab lwm yam kab mob.

Cov sludge dej khib nyiab yuav tsum tau tswj xyuas kom zoo thiab muab pov tseg kom tsis txhob muaj kev phom sij rau kev noj qab haus huv thiab ib puag ncig. Feem ntau, cov sludge tau ua tiav ntxiv kom txo nws cov ntim thiab tshem tawm cov kab mob, tom qab ntawd nws tuaj yeem siv los ua cov av hloov kho, landfilled, incinerated, los yog siv rau lub zog rov qab. Kev xaiv ntawm txoj kev pov tseg yog nyob ntawm hom thiab muaj pes tsawg leeg ntawm cov sludge, nrog rau cov kev cai hauv zos thiab kev xav txog ib puag ncig.

Biological sludge yog ib qho khoom seem uas tshwm sim los ntawm kev kho cov dej khib nyiab uas siv cov txheej txheem lom neeg, xws li kev kho cov sludge los yog anaerobic digestion. Nws muaj cov kab mob microorganisms, organic teeb meem, thiab inorganic solids uas tau raug tshem tawm ntawm cov dej khib nyiab. Biological sludge tuaj yeem kho ntxiv thiab ua tiav kom rov qab tau lub zog lossis cov khoom noj khoom haus, los yog nws tuaj yeem muab pov tseg los ntawm txoj kev xws li kev cog qoob loo lossis kev tsim txom.

Chemical sludge yog ib qho khoom seem uas tshwm sim los ntawm kev kho cov dej khib nyiab, xws li coagulation, flocculation, lossis nag lossis daus, kom tshem tawm cov pa phem. Cov tshuaj sludge feem ntau muaj hlau hydroxides, organic polymers, thiab lwm yam khoom uas tau raug precipitated los yog coagulated tawm ntawm cov dej khib nyiab. Cov tshuaj sludge tuaj yeem kho ntxiv thiab ua tiav kom rov qab tau cov ntaub ntawv tseem ceeb lossis nws tuaj yeem muab pov tseg los ntawm txoj kev xws li landfilling lossis incineration.

Kev lag luam sludge hais txog cov khoom ib nrab lossis cov khoom seem uas tsim los ntawm cov txheej txheem kev lag luam, xws li kev kho dej khib nyiab, mining, thiab kev tsim khoom. Nws tuaj yeem muaj ntau yam khoom uas tsim kev puas tsuaj, nrog rau cov hlau hnyav, cov organic sib txuas, thiab cov kab mob, thiab yuav tsum tau ua tib zoo tuav thiab pov tseg kom tsis txhob muaj kev sib kis ntawm ib puag ncig thiab kev pheej hmoo ntawm kev noj qab haus huv. Cov kev kho mob rau cov sludge muaj xws li dewatering, stabilization, thiab solidification, tom qab ntawd muab pov tseg rau hauv ib qho chaw pov tseg los yog incineration, los yog qee zaum, rov siv tau zoo.

Digested sludge, tseem hu ua biosolids, yog cov khoom siv semi-solid uas tshwm sim los ntawm kev kho cov dej khib nyiab hauv cov chaw kho dej phwj. Nws yog tsim los ntawm cov ntaub ntawv organic thiab inorganic, nrog rau cov kab mob, kab mob, thiab cov as-ham, thiab feem ntau ua tiav ua ntej siv rau kev ua liaj ua teb lossis daim ntawv thov av. Cov txheej txheem digestion txo qhov ntim thiab stabilizes cov organic teeb meem nyob rau hauv cov sludge, ua rau nws tsis muaj ntxhiab tsw thiab yooj yim rau lis.

sludge yog ib qho khoom siv semi-tshuaj uas yog tsim nyob rau hauv thawj lub tso tsheb hlau luam ntawm cov chaw kho dej khib nyiab. Nws muaj cov khib nyiab thiab cov organic uas tau muab tshem tawm ntawm cov dej khib nyiab thaum lub sij hawm thawj txheej txheem kho. Thawj cov sludge feem ntau raug kho ntxiv los ntawm cov txheej txheem xws li kev zom zaub mov anaerobic, aerobic digestion, lossis dewatering, txhawm rau kom ruaj khov cov khoom organic thiab txo nws cov ntim ua ntej pov tseg lossis siv tau zoo.

Qhov tshwj xeeb ntawm cov sludge yuav nyob ntawm qhov chaw thiab txheej txheem kho.
