Vim li cas cov zej zog suav nrog cov feem ntau? Qhov tseem ceeb yog qhov chaw pib ntawm kev siv lead-acid roj teeb rov ua dua yog tsawg. Nyob rau hauv cov xwm txheej tseem ceeb tshaj plaws, ib tus neeg lag luam tuaj yeem tshem tawm cov phaj txhuas, nchuav cov kua qaub ncaj qha, tom qab ntawd teeb lub lauj kaub loj kom sov, muab cov phaj txhuas rau hauv lub lauj kaub kom yaj, thiab ntxiv me ntsis hlau hmoov. Vim cov hmoov txhuas hnyav heev, nws yuav nkag mus rau hauv qab ntawm lub lauj kaub kom tau cov hmoov txhuas rov qab.
Nyob rau hauv qhov tseeb, qhov kev rov qab los ntawm kev cai channel yog tsawg dhau, thiab kev tswj cov pa phem ntawm cov khoom siv lead ua ua tsis tiav hauv 12th Tsib Xyoo Plan. Qhov kev tsis sib haum xeeb yog vim tias cov roj teeb txhuas-acid pov tseg yog cov khib nyiab pov tseg, lawv yuav tsum tau muab tso rau hauv kev tswj cov khoom txaus ntshai los ntawm qhov kawg thiab taug qab hauv txhua qhov txuas ntawm kev ncig. Qhov tseeb yog tias cov roj teeb txhuas-acid raug muag thiab xa tawm raws li cov khoom lag luam zoo tib yam hauv qhov txuas hauv ntej, uas txhais tau hais tias leej twg tuaj yeem yuav lawv thiab tsis tuaj yeem taug qab qhov chaw.
Rau cov chaw tsim khoom siv lead-acid roj teeb thaum kawg, lawv yuav tsum muaj kev tswj xyuas cov khoom pov tseg pov tseg, thaum tsuas muaj 34 lub tuam txhab uas tau txais daim ntawv tso cai ua haujlwm ntawm cov khib nyiab txhuas-acid roj teeb hauv Suav teb. Tsuas muaj ib lossis ob lub tuam txhab tsim nyog hauv txhua lub xeev, thiab qee lub xeev thiab cheeb tsam tseem tsis muaj lawv. Piv txwv li, tsis muaj peev xwm ua tau cov kua qaub roj teeb rov ua haujlwm kho mob hauv Xinjiang. Yog hais tias Xinjiang xav kom muaj kev cuam tshuam nrog cov roj lead-acid roj teeb, nws yuav tsum dhau los ntawm cov txheej txheem ntawm kev hloov pauv cov pov tseg hauv xeev, thiab tseem mus dhau daim ntawv hla tebchaws, uas yog teeb meem heev, kim thiab nyuaj.
Raws li qhov tshwm sim, ntau tus neeg ua haujlwm tus kheej thiab cov neeg yuav khoom txawv teb chaws tsis muaj kev phom sij rau kev lag luam pov tseg tau tswj cov khoom siv rov ua dua tshiab ntawm cov roj ntsha txhuas, thiab "guerrillas" tau nyiag kev lag luam ntawm "cov tub rog tsis tu ncua". Tus lwm thawj coj ntawm cov khoom siv hlau rov ua dua tshiab ntawm Tuam Tshoj Nonferrous Metals Industry Association tau hais tias muaj kwv yees ntau pua qhov chaw tsim khoom siv lead ua tsis raug cai, feem ntau hauv Henan, Jiangxi, Hebei, Shandong thiab lwm qhov chaw. Tian Jianguo ob lub taub hau smelters yog ib feem ntawm qhov kev lag luam hauv av loj.
