Ob peb xyoo dhau los, noob neej tau tsim cov khoom pov tseg hauv tsev loj heev. Hauv lub nroog niaj hnub no, kwv yees li 300 kg ntawm cov khib nyiab ib xyoos ib zaug, yog li kev rov ua dua yog ib qho teeb meem nyuaj tshaj plaws niaj hnub no.

Kev tshem tawm thiab pov tseg cov khoom pov tseg hauv tsev yog ib qho haujlwm tshwj xeeb uas yuav tsum tau siv cov cuab yeej tshwj xeeb. Nyob rau hauv cov txheej txheem ntawm kev ua, nws yog ib qho tsim nyog tsis yog tsuas yog los saib xyuas kev siv ntau cov qauv thiab cov cai, tab sis kuj siv cov tshuab thiab cov cuab yeej siv. Feem ntau, kev lag luam pov tseg muaj cov khoom tsim kev puas tsuaj rau tib neeg - hlau hnyav, dioxides, fluorine compounds. Tag nrho cov ntawm lawv yog heev txaus ntshai rau tib neeg noj qab haus huv. Cov khoom tsis zoo nrog cov dej nag nkag mus rau hauv av, sulfur dioxide thiab methane raug tso tawm rau hauv huab cua ntau heev. Cov khib nyiab hauv qhov chaw pov tseg ua rau muaj kev pheej hmoo ntawm kev sib tsoo. Tsis tas li ntawd, cov pov tseg tsis raug cai yog chaw yug tsiaj rau kab thiab nas.

Ib txoj hauv kev niaj hnub rau qhov teeb meem no yog kev pov tseg ntawm tsev neeg pov tseg thiab muaj peev xwm siv lawv ntxiv. Siv sijhawm, lub zog thiab nyiaj txiag ntawm kev pov tsegkhib nyiab. Txawm li cas los xij, cov thev naus laus zis niaj hnub tso cai tsis yog tsuas yog ua kom muaj kev nyab xeeb ntawm cov khoom pov tseg, tab sis kuj tau txais txiaj ntsig los ntawm nws. Kev pov tseg ntawm cov khoom pov tseg hauv tsev yuav tsum tau ua qee yam, vim tias nws yuav rov siv tau dua.

Cov ntawv pov tseg, cov hlau nplaum thiab iav tuaj yeem siv ncaj qha. Kev tsim cov khib nyiab uas tsis hloov nws cov khoom tuaj yeem muab faus rau hauv av. Cov khib nyiab feem ntau yog siv los tsim roj. Cov roj tau txais tom qab ua cov khoom pov tseg yog sib npaug hauv qhov zoo rau xim av thee thiab peat. Cov kws tshawb fawb ntseeg tias lub zog tau txais los ntawm kev hloov cov khib nyiab rau hauv lub zog thiab roj yuav tuaj yeem npog ib feem peb ntawm cov kev xav tau ntawm lub ntiaj teb kev lag luam. Lwm qhov kev siv cov khib nyiab khib nyiab yog zom nws thiab tig mus rau hauv cov khoom siv hauv tsev. Piv txwv li, crushed thiab compressed yas yog tov nrog asph alt thiab roj av resins thiab siv los tsim txoj kev. Shredded yas kuj yog siv los tsim cov yeeb yaj kiab, cov ntaub ntawv vov tsev thiab cov khoom ua si.

Kev pov tseg ntawm tsev neeg pov tseg uas yuav tsum tau kho nruab nrab - cov no yog alkalis, acids, roj pov tseg. Ib feem ntawm cov sludge yog dehydrated thiab qhuav. Qee cov khoom siv hluav taws xob, xws li cov roj siv thiab cov yas siv, yog incinerated. Ntawm cov chaw tsim khoom pov tseg niaj hnub no, kev pov tseg ntawm tsev neeg thiab kev lag luam pov tseg tau tsim, tshwj xeeb thev naus laus zis tso cai rau sorting, crushing cov khib nyiab thiab txheeb xyuas cov feem,txaus ntshai rau ib puag ncig thiab tib neeg kev noj qab haus huv. Nyob rau hauv lub ntiaj teb no, uncontrolled tsub zuj zuj ntawm tsev neeg thiab industrial pov tseg hem kom hloov qhov sib npaug ntawm oxygen thiab carbon dioxide nyob rau hauv cov xwm, txo tus nqi ntawm cov dej huv. Lawv ua rau cov av muaj kuab paug thiab degradation ntawm lub cev dej, kev hloov pauv huab cua. Lub luag haujlwm tseem ceeb tshaj plaws ntawm kev lag luam hauv ntiaj teb yog los xyuas kom meej tias cov khoom pov tseg hauv tsev tau txav los ntawm ntau yam kev phom sij mus rau ntau cov thev naus laus zis zoo.
