Basa rekushandura rakasvibirira richiri rakaoma.Indasitiri yesimbi inoda kuziva matambudziko matatu
Zhang Dawei akataura kuti tichiita budiriro, tinofanirawo kuziva zvine hungwaru matambudziko matatu akatarisana nesu.
Kutanga, miuyo yekudzora haisati yagadzikana, uye mugariro wokushatiswa kwemhepo uchiri wakakomba.Kunyangwe iyo nyika PM2.5 kusungwa kwadzikira kusvika pamakumi maviri nemapfumbamwe mamicrograms pacubic mita muna 2022, ichiri yakapetwa kaviri kana kana nhanho iripo munyika dzeEurope neAmerica, uye katanhatu kukosha kweiyo WHO."Munyika yedu, chikamu chimwe muzvitatu chemaguta hachisati chasvika pachiyero, kunyanya chakatarisana munzvimbo dzine vanhu vakawanda nechepakati nekumabvazuva, uye maguta mazhinji ane simbi nesimbi yekugadzira simbi haisati yasvika pachiyero.""Unhu hwemhepo huchiri kutadza kusvika pachinangwa chekuvaka China yakanaka uye chinodikanwa chemazuva ano chekugarisana kwakanaka pakati pemunhu nezvisikwa," akadaro Zhang.Hunhu hwemhepo hunogona kudzoka nyore nyore kana paine chikanganiso chidiki. "
Chechipiri, matambudziko ezvimiro akatanhamara, uye kushandurwa kwegirini kwesimbi nesimbi kunoramba kuri basa refu uye rakaoma.Zhang Dawei akataura kuti kuburitswa kwesarufa dioxide, nitrogen oxide uye zvinhu kubva muindasitiri yesimbi zvichiri kukwira pakati pemaindasitiri, uye kuburitswa kwecarbon dioxide (15 muzana) zvakare kuri pekutanga pakati pemakambani asiri-magetsi.Kana chekufambisa chawedzerwa, kuburitswa kwakatonyanya."Chikonzero ndechekuti matambudziko emuindasitiri pachayo haana kunyatsovandudzwa."Akataura kuti, kana hurongwa hwekuita huchidzorwa nemaitiro akareba, kubuda kwesimbi yechoto yemagetsi kunongotora 10% chete yehuwandu hwekubuda kwesimbi isina kuchena, iro mukaha mukuru neavhareji yepasi rose ye28%, 68% mukati. United States, 40% muEuropean Union uye 24% muJapan.Mamiriro emuchaji anonyanya kunyura nekubuda kwakanyanya, uye chikamu chepellets muchoto chiri pasi pe20%, inova gaka rakakura nenyika dzeEurope neAmerica.Chimiro chesimba chinotungamirirwa nemarasha.Marasha anoita 92% yesimba rakatengwa neindasitiri yesimbi nesimbi.Maindasitiri ekushandisa marasha anoita makumi maviri muzana ehuwandu hwemarasha anoshandiswa munyika (kusanganisira coking), ari wekutanga muindasitiri isiri yemagetsi.Zvichingoenda zvakadaro.
Pamusoro pezvo, indasitiri iyi haina matura akakwana emakiyi matekinoroji ekudzikisa kusvibiswa uye kabhoni."Zviri kukurumidza kuputsa zvipingamupinyi zvehunyanzvi uye zvemitemo pakati pemaindasitiri esimbi nemakemikari, kukurudzira kukurudzira kwehunyanzvi hwekuvandudza tekinoroji muindasitiri iyi, uye nekumhanyisa tsvakiridzo nekushandiswa kweinjiniya yekuvhiringidza uye yekuvandudza yakaderera kabhoni metallurgical tekinoroji."Zhang Dawei akataura kuti mune yazvino "double carbon" kumashure, indasitiri yesimbi yakasvibira yakaderera-kabhoni shanduko basa rakaoma.
Chechitatu, kufambira mberi mukubuda kwakaderera-shoma kunoenderana nezvinotarisirwa, asi mamwe matambudziko haafanire kufuratirwa.Kutanga, kufambira mberi mune mamwe matunhu kunosarira kumashure.Makambani akanyorwa akanyanya kutariswa mudunhu reBeijing-Tianjin-Hebei nenzvimbo dzakatenderedza uye Fen-Wei Plain, nepo Yangtze River Delta dunhu rakaita zvishoma kufambira mberi.Parizvino, mabhizinesi e5 chete munzvimbo dzisiri-akakosha apedza shanduko yese uye akazvizivisa.Mabhizinesi mazhinji mune mamwe matunhu ari mudanho rekutanga reshanduko.Chechipiri, mhando yemamwe mabhizinesi haina kukwirira.Mamwe mabhizinesi ane mamwe matambudziko, akadai seasina musoro sarudzo sarudzo, isina kukwana shanduko, kusimbisa magumo-kutonga pamusoro pekudzivirira uye kutonga.Chechitatu, kunaka kwekuongorora nekutarisa basa kunoda kuvandudzwa."Mamwe makambani haasati agadzirira kugadzirisa, kuitira kuti abudise pachena, pakuongorora uye kuongorora 'pfungwa dzakakombama', basa racho harina kuomarara uye harina kusimba, uye kunyange manyepo."Zhang Dawei akataura kuti kuitira kuvandudza hunyanzvi hwekuongorora nekutarisa basa, Ministry of Ecology and Environment uye Steel Association vakaita hurukuro dzakawanda muna 2022, vachisundidzira sangano kuti rimise template remushumo uye kumanikidza kushambadza, asi dambudziko richiri. riripo nemwero yakasiyana-siyana.”"Akataura.Chechina, mabhizinesi ega anozorodza manejimendi mushure mekushambadzira, uye kunyangwe maitiro asiri pamutemo.
Yakakwira mwero kuchengetedzwa kwezvakatipoteredza, indasitiri yesimbi uye mabhizinesi kuita ina "kutarisisa"
Zhang Dawei akati kutariswa kwese kweBazi reEcology uye Zvemamiriro ekunze gore rino kutevedzera "matanho matatu ekudzora kusvibiswa" uye "matanho mashanu echokwadi", achipikisa zvakasimba "saizi imwe inokodzera-zvese", kupokana nekuisirwa. yezvikamu zvakawanda.Paunenge uchiita kutonga kwemhepo, shumiro inoronga kushanda zvakanaka kweindasitiri uye zviwanikwa garandi, uye kusimudzira kusimudzira kwemhando yepamusoro yeindasitiri yesimbi ine yakakwirira yekudzivirira.
"Zvinokurudzirwa kuti indasitiri yesimbi nemabhizinesi anofanirwa kubata ne'hukama hutatu', ndiko kuti, kugadzirisa hukama pakati pezvinokonzeresa nemidzi, zvenguva refu uye zvenguva pfupi, kusimudzira nekuderedza kuburitsa, uye kuita zvina." kunyanya kutariswa'.Zhang Dawei akakurudzira.
Chekutanga, isu tinozonyanya kutarisisa kune zvimiro uye masosi ekudzikisa emission matanho."Pasi pechinangwa chezvino 'mbiri-kabhoni' chinangwa, isu tinofanirwa kutarisisa zvakanyanya kune zvimiro, kunobva uye mamwe matanho.Musika wenguva yemberi wekabhoni uye mutero wekabhoni uchave nemhedzisiro inosvika kure mukusimudzira indasitiri, uye isu tinofanira kutora maonero enguva refu. "Zhang akakurudzira kuti indasitiri yesimbi inofanira kuisa pfungwa pakuwedzera chikamu chekugadzirwa kwesimbi kwenguva pfupi mumagetsi emagetsi;Wedzera chikamu chepellets inoshandiswa mumoto unoputika uye kuderedza kushandiswa kwe sinter;Tichavandudza kushandiswa kwesimba, kuwedzera chikamu chemagetsi egirini anoshandiswa, uye kutsiva simba rakachena muvira remaindasitiri anobatidzwa nemarasha.Mabhizinesi epakati neehurumende anofanirwa kuita basa rinotungamira uye kutungamira mukuratidzira nekushandisa kwekudyidzana tekinoroji hunyanzvi mukuderedza kusvibiswa uye kabhoni.
Chechipiri, isu tinozobhadhara zvakanyanya kune kunaka kweiyo ultra-low emission shanduko.Iyi purojekiti hombe haingomanikidzi mabhizinesi kusanganisa nekuronga patsva, kusimudzira michina, uye kuvandudza girinhi uye yakaderera-kabhoni kusimudzira kweindasitiri yesimbi, asi zvakare kuwedzera hunobudirira hwekudyara kwevanhu uye kubatsira kudzikamisa kukura kwehupfumi."Takasimbisa kakawanda pazviitiko zvakasiyana-siyana kuti shanduko yepamusoro-soro inofanirwa kuyedza kuti 'ina yechokwadi', iwane 'ina inofanirwa uye ina haiite', uye inofanirwa kumira muyedzo yenhoroondo."Zhang Dawei akadaro.
Chechitatu, isu tinozobhadhara zvakanyanya kuzadzisa zvidikanwi zve-ultra-low pane zvakatsiga uye zvakagadzikana."Mabhizinesi apedza kushanduka kwekupedzisira-yakaderera emission uye kushambadza anofanirwa kusimbisa mabasa emasangano ekuchengetedza zvakatipoteredza, kusimudzira hunyanzvi hwehunyanzvi hwevashandi vekuchengetedza kwezvakatipoteredza, uye kupa mutambo wakazara kune basa rekutsigira rakarongeka, risina kurongeka uye rakachena rekutarisa nzira yekufambisa. yekutarisira kwezvakatipoteredza yakagadzwa mune yekupedzisira-yakaderera emission shanduko maitiro, kuitira kuti uwane yakagadzikana ekupedzisira-yakaderera emissions.Hazvisi nyore kuita.”Zhang Dawei akasimbisa kuti kuburitswa kwesimbi kwazvino kwave kuumba nzira yekutarisa mapato akawanda inosanganisira hurumende, mabhizinesi neveruzhinji.
Akataura kuti mudanho rinotevera, Ministry of Ecology and Environment ichatungamira hurumende dzenzvimbo kuti dzishandise zvizere marongero akapatsanurwa, kuwedzera tsigiro yemitemo yemabhizinesi akagadzikana ekupedzisira-akaderera emission, uye kukumbira Steel Association kuti ibvise ziviso yeveruzhinji yemabhizinesi ayo. haigone kuwana ultra-low emission uye kuita zvisiri pamutemo maitiro.Nekune rimwe divi, isu tichawedzera kuongororwa kwemitemo uye kutarisisa kwakasimba kwemabhizinesi asina kupedzisa shanduko yeakanyanya-yakaderera emissions.
Chechina, teerera zvakanyanya kudzikisa kusvibiswa uye kabhoni muzvifambiso zvinongedzo.Indasitiri yesimbi neyesimbi ndiyo yakakosha indasitiri muhondo yekurwisa marori edhiziri, uye zvinobuda kubva kune zvekufambisa zvinosvika makumi maviri muzana ehuwandu hwekuburitswa kwechirimwa chose."Nhanho inotevera, mabhizinesi anofanirwa kutarisisa kukwenenzverwa kwekufambisa mukati nekunze kwechirimwa, kuvandudza chikamu chekutakura kwakachena kwezvinhu uye zvigadzirwa kunze kwechirimwa, zvepakati uye kureba zvekufambisa nechitima kana nzira yemvura, yepakati uye pfupi nhambwe yekufambisa. pombi gallery kana itsva simba motokari;Kuvakwa kwebhandi, track uye roller tafura yekufambisa system ichaitwa mufekitori kudzikisa huwandu hwekufambisa kwemotokari mufekitori nekukanzura kuendeswa kwechipiri kwezvinhu mufekitori. "Zhang Dawei akati, yakashambadzirwa, kune matanhatu ekufambisa mota modhi yemabhizinesi, akakurudzirawo kuti isu tiwedzere kukwidziridza chimiro chekufambisa, kuvandudza chikamu chekufambisa kwakachena.
