Vim yog tus nqi qis, kev ua haujlwm ruaj khov yog qhov zoo, lub roj teeb tau dav siv hauv tsheb fais fab, lub zog cia thiab lwm yam. Tus naj npawb ntawm cov khoom pov tseg uas tau tshwm sim hauv kuv lub tebchaws tau tshaj 3.3 lab tons, thiab nws cov kev siv thiab pov tseg tseem nce ntxiv ib xyoos ib zaug.

Tam sim no, kuv lub teb chaws tseem tsis tau tsim cov txheej txheem rov ua haujlwm zoo, thiab qhov kev rov ua haujlwm tsis tu ncua yog tsawg dua 30%. Ministry of Industry thiab Information Technology, Department of Environmental Protection, Beijing-Tianjin, Roj teeb, Environmental Protection Industry, thiab lwm yam. Cov kev tshawb fawb yav dhau los qhia: 80% ntawm cov roj teeb pov tseg rov qab los ntawm thaj chaw Beijing-Tianjin-Hebei tau paub txog cov kev sib raug zoo tsis raug cai, lub tuam txhab roj teeb ib txwm rov qab tau me me, kev tsim kho cov tuam txhab ua lag luam 80% ntawm cov khoom siv raw kuj yog los ntawm kev txhaum cai.

Ze li ntawm 160,000 tons ntawm txhuas txhua xyoo, cov peev txheej muaj kuab paug vim kev coj tus cwj pwm tsis tu ncua, tsis muaj kev siv cov chaw tiv thaiv ib puag ncig zoo, ntau cov roj teeb pov tseg tau raug txiav tawm, ua rau cov pa roj, av thiab dej paug. "Kev coj cwj pwm tsis tu ncua tsis yog tsuas yog cuam tshuam rau ib puag ncig thiab tib neeg txoj kev noj qab haus huv xwb, tab sis kuj ua rau cov khoom pov tseg loj ntawm cov khoom siv lead ua pov tseg thiab kev poob se hauv lub tebchaws. Zhang Tian hais tias.

Raws li kev txheeb cais, kuv lub teb chaws tau txais cov cuab yeej siv qib siab thiab thev naus laus zis, cov txhuas rov qab tau nce siab dua 99%, ntau dua 98% ntawm cov hlau lead rov qab los ntawm cov teb chaws tsim. Txawm li cas los xij, "peb tsis muaj lub tuam txhab" ntawm kev smelting tsis raug cai yog tsawg, feem ntau tsuas yog 80% -85%, nrog rau qhov siab tshaj plaws ntawm 90%, ua rau kwv yees li ntawm 160,000 tons ntawm txhuas txhua xyoo hauv cov txheej txheem smelting tsis raug cai, dhau los ua cov pa phem thiab tib neeg kev noj qab haus huv txaus ntshai. Thiab rov qab tsis raug cai, smelted roj teeb txaus siab, uas kuj ua rau ze li ntawm 15 billion yuan ib xyoos twg.

"Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Hluav Taws Xob Hluav Taws Xob" tawm los ntawm Ministry of Ecological Ib puag ncig ntawm Ecological Ib puag ncig yog muab tawm yam tsis muaj nqi ib puag ncig, thiab los ntawm 2020, lub tuam txhab tsim cov roj teeb siv cov roj teeb pov tseg los ntawm kev siv cov khoom tsim tawm lub luag haujlwm txuas ntxiv. Tus qauv sau tus nqi yog 40%; mus txog 2025, cov khib nyiab cia roj teeb specification sau tus nqi nce mus txog 70%; tag nrho cov roj teeb pov tseg uas tau sau tseg yog txhua yam muaj txiaj ntsig zoo. Zhang Tian tau hais tias lub roj teeb rov ua dua yog qhov tseem ceeb los ntawm kev nyiam ua lag luam, tsis muaj kev rov ua dua tshiab.

Hauv qee thaj chaw muaj neeg coob coob, cov roj teeb pov tseg tau dhau los ua cov peev txheej rau cov tuam txhab tsim kho tshiab los sib tw rau kev sib tw. Qee lub tuam txhab kev tsim kho tshiab hauv av tsis raug cai "tus nqi siab" snapped, ua rau muaj kev txaj muag ntawm "tsis muaj nplej" hauv kev tsim kho tshiab. Lub tuam txhab tsis raug cai tau ua tiav qhov chaw sib tw ntau dua vim tsis muaj cov nqi kho mob, tab sis tuaj yeem txhim kho tus nqi ntawm cov khoom siv raw.

70% ntawm cov khoom nyob rau hauv lub roj teeb yog txhuas, nrog ib tug siab rov qab thiab rov siv tau tus nqi. Tam sim no, tus nqi rov qab ntawm cov khib nyiab cia roj teeb yog kwv yees li 9,000 yuan / tuj, thiab tus nqi ntawm cov hmoov txhuas rau smelting tshaj 18,000 yuan / ton. Kev ua txhaum cai rov ua dua tshiab, rhuav tshem thiab smelting tuam txhab lag luam tsis muaj kev tiv thaiv ib puag ncig, cov txiaj ntsig ntawm ib tuj ntawm cov hlau lead ingots tshaj 2,000 yuan.

Ma Yongang, tus lwm thawj coj ntawm Lead thiab Zinc Ceg ntawm kuv lub teb chaws Lub Koom Haum Kev Lag Luam Tsis Muaj Xim Hlau, tau hais tias vim tias tus nqi qis, cov tuam txhab tsis raug cai feem ntau nce nqi thaum lawv rov siv roj teeb, tus nqi qis thaum muag cov khoom siv lead ua, kom cov tuam txhab tsis tu ncua "ob lub taub hau" yog nyem. Kev rhuav tshem kev rov qab los thiab kev ncig ntawm cov pa phem los txhawb kev txhim kho ntsuab ntawm kev lag luam roj teeb. Txij li thaum "Kaum Ib Hlis Tsib Xyoo", Ministry of Environmental Protection, Ministry of Industry thiab Information Technology, tau tshaj tawm txoj kev tswj hwm tshwj xeeb hu ua "Qhov kev nruj tshaj plaws hauv keeb kwm", thiab tam sim no los ntawm 132 cov tuam txhab tseem ceeb hauv "Standard Conditions ntawm Roj Teeb Kev Lag Luam" los ntawm Ministry of Industry thiab Information Technology, cov tuam txhab roj teeb muaj peev xwm txo qis los ntawm 2013 ntawm 2014 ntawm kev lag luam concentration, 2014. tau nce ntau heev.

Nws kuj tau ua tiav cov txiaj ntsig tseem ceeb hauv roj teeb kev lag luam hloov pauv thiab kev txhim kho ntsuab. Tom qab cov roj teeb pov tseg tau raug rho tawm tsis raug cai, cov hmoov lead hauv cov kua qaub yuav xau hauv ib puag ncig, ua paug rau cov av thiab dej hauv av. Raws li kev lag luam sab hauv, tom qab kev tswj hwm tshwj xeeb ntawm lub teb chaws, kuv lub teb chaws lub tuam txhab loj loj nruab nrab ntawm cov roj teeb tsim tam sim no tau nkag mus rau hauv kev tsim ntsuab ecological, txiav cov pa phem los ntawm qhov chaw.

Yog tias lub roj teeb uas muaj cadmium uas muaj arsenic roj teeb raug tshem tawm tag nrho; lub roj teeb qhib lub qhov ncauj uas yooj yim los ntawm cov pa phem yog hloov los ntawm lub valve sealing roj teeb tshiab. Thiab los ntawm kev hloov kho thev naus laus zis thiab kev siv tshuab hluav taws xob, cov cuab yeej tsim khoom ntse, tiv thaiv cov khoom siv roj teeb los ntawm kev tsim thiab emissions hauv kev tsim khoom, muaj kuab paug thaum siv, txo cov peev txheej poob thiab kev pheej hmoo ntawm ib puag ncig. Tam sim no, cov pa phem ntawm kuv lub teb chaws cov roj teeb kev lag luam yog tsom rau kev rov ua dua thiab kev ncig, thaum lub roj teeb khib nyiab rov qab thiab cov khoom siv hauv tsev pov tseg muaj teeb meem zoo sib xws.

Ma Yonggang thiab lwm tus kws tshaj lij ntseeg tias cov kev cai xws li kev cia khoom pov tseg, rov ua dua tshiab, kev thauj mus los, thiab lwm yam. yuav tsum tau txhim kho, tsim kom muaj kev tswj xyuas qhov tseeb, thiab lwm yam. Zhang Tianyi qhia tias tsoomfwv yuav tsum nce kev saib xyuas ntawm ib puag ncig muaj kuab paug txaus ntshai, tiv thaiv kev rov ua dua tshiab ntawm cov roj teeb pov tseg tsis raug cai, kev tsim cov hlau lead tsis raug cai thiab ua rau muaj kev ua qias tuaj ib puag ncig, tshawb nrhiav, cuam tshuam nrog kev zam se, kev zam se hauv cov txheej txheem roj teeb noj se, rau cov tuam txhab roj teeb uas muaj kev sib tw ncaj ncees rau kev lag luam ib puag ncig, thiab lwm yam.
