Nyob rau hauv xyoo tas los no, Tuam Tshoj txoj kev tswj hwm kev lag luam VOCs yog nyob rau theem ntawm kev loj hlob sai, kev lag luam nplai tau nthuav dav heev. 2020 yuav ncav cuag 140 billion yuan mus rau 150 billion yuan, thiab tsib lub xyoos tom ntej no, lub lag luam no xav kom ntau tshaj 300 billion yuan. Hauv tsib xyoos tom ntej no, kev lag luam loj yuav tsum tshaj 300 billion yuan.
Ua raws li "13th Tsib Xyoo Plan" kev tiv thaiv thiab kev tswj hwm zoo (PM2.5) tau ua tiav qhov tseem ceeb, Tuam Tshoj txoj kev tiv thaiv thiab kev tswj hwm huab cua tau qhib rau kev sib ntaus sib tua tshiab: kev tswj hwm ozone. Qhov no tseem yuav yog "Tshaj Plaub Tsib Xyoo" ntawm Tuam Tshoj txoj kev tiv thaiv huab cua thiab kev tswj hwm ntawm thaj chaw tseem ceeb, thiab lub hom phiaj tseem ceeb yog cov organic tebchaw tsis zoo (VOCs).
Kev tswj hwm VOCs yuav tsum nruj
Nyob rau hauv xyoo tas los no, qhov teeb meem ntawm cov pa phem ozone tau dhau los ua qhov tseem ceeb thoob ntiaj teb. Kev soj ntsuam cov ntaub ntawv qhia tau hais tias nyob rau hauv 2019, qhov nruab nrab txhua xyoo concentration ntawm ozone nyob rau hauv 337 lub zos nyob rau hauv prefecture theem thiab saum toj no yog 148 micrograms ib cubic meter, nce 21 feem pua piv rau 2015; Tus naj npawb ntawm cov hnub nrog ozone raws li thawj cov pa phem tshaj tus qauv suav nrog 42 feem pua ntawm tag nrho cov hnub dhau mus, thib ob tsuas yog PM2.5 (45 feem pua).
Liu Bingjiang tau hais tias "Thaum txuas ntxiv txhawb PM2.5 kev tswj hwm kev ua qias tuaj, nws yog qhov yuav tsum tau ua kom muaj kev tswj hwm kev ua qias tuaj rau ozone kom txwv kev nce siab hauv ozone concentration," Liu Bingjiang tau hais tias, "uas yuav tsum tau ua raws li VOCs tswj hwm kev tawm tsam hauv tag nrho cov txheej txheem thiab tag nrho. yam."
VOCs feem ntau pom muaj nyob rau hauv cov khoom siv raw thiab cov khoom lag luam. Kev txheeb ze rau kev tswj cov pa phem ntawm cov khoom me me, sulfur dioxide thiab nitrogen oxides, Tuam Tshoj tus VOCs tswj lub hauv paus tsis muaj zog thiab tau dhau los ua lub rooj tsav xwm luv luv hauv huab cua thiab kev tswj hwm ib puag ncig. Petrochemical, chemical, industrial painting, ntim thiab luam ntawv, thiab kev lag luam roj thiab kev thauj mus los yog qhov tseem ceeb emissions ntawm VOCs.
Ib tus kws tshawb fawb ib zaug tau saib xyuas lub tank roj av uas muaj cov xau loj, uas tuaj yeem ua rau muaj ze li 100 tons ntawm cov roj av hauv ib xyoos, ua rau kev lag luam ncaj qha los ntawm ntau pua txhiab yuan. Txoj kev tshawb no qhia tau hais tias qhov concentration ntawm VOCs nyob ib puag ncig ntawm cov roj depot tau loj heev, thiab hais tias nyob rau hauv qee lub nroog, cov emission ntawm VOCs tshwm sim los ntawm volatilization ntawm cov khoom roj tuaj yeem suav txog 10 feem pua rau 20 feem pua ntawm VOCs qhov chaw.
Raws li Kev Suav Pej Xeem Hauv Tebchaws Thib Ob, VOCs emissions los ntawm cov roj cia thiab muag ib leeg muaj txog li 500,000 tons hauv ib xyoos. Tsis tas li ntawd, VOCs feem ntau yog cov nplaim taws thiab tawg, qee qhov ntawm lawv yog cov tshuaj lom neeg thiab muaj kev phom sij, thiab qee qhov ntawm lawv yog cov ntxhiab tsw phem, thiab cov neeg coob coob tshaj tawm cov lus tsis txaus siab.
Kev tshawb xyuas los ntawm cov tub ceev xwm ib puag ncig pom tau tias, tam sim no, cov tuam txhab uas muaj ntau qhov loj thiab thaj chaw loj ntawm kev tsim khoom tsis tau siv cov kev tswj xyuas zoo, uas qhib kev cia, hloov thiab tsim cov khoom uas muaj VOCs yog ib txwm muaj, uas pov tseg VOCs-muaj cov ntaub ntawv. tsis tswj nyob rau hauv qhov chaw, thiab qhov ntau ntawm VOCs pov tseg (kua thiab slag) thiab cov ntim ntim pov tseg tsis raug pov tseg kom raws sijhawm.
Tsis tas li ntawd, lub chaw haujlwm ib puag ncig kev tshawb nrhiav tseem pom tias Tuam Tshoj txoj kev tswj hwm VOCs kev lag luam kev lag luam nkag mus rau qhov pib muaj tsawg, kev sib tw nqi qis yog nquag, ua rau muaj kev tswj hwm kev tswj hwm, kev tswj tsis tau zoo thiab lwm yam kev kub ntxhov, cuam tshuam kev lag luam kev lag luam.
Kev tshawb fawb pom tias kev lag luam tam sim no VOCs kev tswj hwm cov chaw pov tseg cov roj sau feem ntau yog qis, ntau cov khoom siv khib nyiab hauv zos tsis muaj txiaj ntsig. Qee qhov chaw ntawm cov ntshav qis qis, photocatalytic, photo-oxidation thiab lwm yam kev siv thev naus laus zis tsis zoo ntawm VOCs kev tswj hwm tau mus txog ntau dua 80 feem pua; qee qhov kev lag luam kawg ntawm kev tswj hwm siv adsorption, nqus cov txheej txheem, lub sij hawm ntev tsis hloov cov khoom adsorbent thiab absorbents. Qee lub tuam txhab siv combustion thiab condensation VOCs kev tswj hwm thev naus laus zis, tab sis kev ua haujlwm kub tsis ua raws li cov qauv tsim, yog li cov txiaj ntsig tiag tiag tau txo qis, thiab tseem muaj qee lub tuam txhab tsim kev tswj hwm yam tsis tau siv.
Txij li xyoo 2017, lub teb chaws tau tshaj tawm cov ntaub ntawv xws li 13th Tsib Xyoo Plan VOC Kev Tiv Thaiv Kev Tiv Thaiv thiab Tswj Kev Ua Haujlwm, Kev Npaj Ua Haujlwm VOC rau Kev Lag Luam Tseem Ceeb, thiab 2020 VOC Management Tackling Plan, uas xav kom meej meej tias los ntawm 2020, lub suab. VOCs kev tiv thaiv kev ua qias tuaj thiab kev tswj hwm kev tswj hwm raug tsim, cov cheeb tsam tseem ceeb thiab cov kev lag luam tseem ceeb tau ua tiav cov txiaj ntsig tseem ceeb hauv kev tswj hwm VOCs, thiab lub hom phiaj ntawm kev txo qis VOCs emissions los ntawm 10 feem pua ntawm 13th Tsib Xyoo Plan ua tiav.
Kev tswj hwm VOCs tau tshawb nrhiav thiab ua tiav cov txiaj ntsig hauv ntau qhov chaw.
Raws li cov kws tshuaj ntsuam xyuas kev lag luam, nyob rau xyoo tas los no, Tuam Tshoj VOCs kev lag luam kev lag luam yog nyob rau hauv ib theem ntawm kev loj hlob sai, concentration yuav nce ntxiv, VOCs tswj kev lag luam loj tau nthuav dav. 2020 yuav ncav cuag 140 billion yuan rau 150 billion yuan. Hauv tsib xyoos tom ntej no, qhov ntsuas ntawm qhov kev lag luam no yuav tsum muaj tshaj 300 billion yuan.
VOCs online tsis ntev los no tau tshaj tawm cov txiaj ntsig kev tshawb fawb qhia tau hais tias, raws li kev paub dhau los ntawm cov tebchaws tsim hauv kev tswj hwm huab cua, kev tshem tawm cov pa roj av, flue gas desulfurization, flue gas denitrification thiab VOCs kev tswj hwm kev lag luam yog nyob rau hauv kev sib raug zoo ntawm kev sib kis, thiab kev lag luam voj voog ntawm kev tswj hwm VOCs ntev dua.
