Ukushiswa kwemfucuza, emehlweni abantu abaningi, kubonakala kukhiqiza ukungcola kwesibili, futhi i-dioxin ekhiqizwa kuyo iyodwa yenza abantu bakhulume ngakho.Nokho, emazweni athuthukile okulahlwa kwemfucuza njengeJalimane neJapane, ukushiswa kwemfucuza kuyisici esivelele, ngisho nesixhumanisi esiyinhloko, sokulahlwa kwemfucuza.Kula mazwe, izindawo zokushiswa kwemfucuza eminyene azizange zinqatshwe ngokuvamile abantu.Kungani lokhu?
Sebenza kanzima ekwelashweni okungenangozi
Le ntatheli isanda kuvakashela i-Taisho Waste Treatment Plant ngaphansi kwe-Environmental Bureau yase-Osaka City eJapane.Lapha akunciphisi kakhulu kuphela inani le-Waste ngokushisa izinto ezivuthayo, kodwa futhi kusebenzisa kahle ukushisa kwemfucuza ukukhiqiza ugesi futhi kunikeze amandla okushisa, okungashiwo ukuthi kusebenzela izinhloso eziningi.
Izimfuneko zokushiswa kukadoti ukuze kudlale izindima eziningi ngesikhathi esisodwa kufanele kube ukuphepha nokungcoliswa okuncane.Intatheli ibone endaweni yefekthri yeDazheng Waste Treatment Plant ukuthi i-Waste shaft enkulu ingamamitha angu-40 ukushona futhi inamandla angu-8,000 cubic metres, ongathwala cishe amathani angu-2,400 we-Waste.Abasebenzi balawula bekude u-crane ngemuva kodonga lwekhethini lengilazi phezulu, futhi bangakwazi ukubamba amathani angu-3 emfucumfucu ngesikhathi bese beyithumela endaweni yokushisa.
Nakuba kune-Waste engaka, alikho iphunga elibi endaweni yefekthri.Lokhu kungenxa yokuthi iphunga elikhiqizwe i-Waste likhishwa isiphephetha-moya esikhipha umoya, sishisiswe sibe ngu-150 kuya ku-200 degrees Celsius nge-preheater yomoya, bese sithunyelwa kumshini wokushisisa.Ngenxa yokushisa okuphezulu esithandweni, izinto ezinuka kamnandi zibolile.
Ukuze kugwenywe ukukhiqizwa kwe-carcinogen dioxins ngesikhathi sokushiswa, isishisi sisebenzisa izinga lokushisa eliphezulu elingu-850 kuya ku-950 degrees Celsius ukuze sishise ngokuphelele Imfucuza.Ngesikrini sokuqapha, abasebenzi bangabuka isimo ngaphakathi kwendawo yokushisela ngesikhathi sangempela.
Uthuli olukhiqizwa ngesikhathi senqubo yokushiswa kwemfucuza lumuncwa umqoqi wothuli kagesi, futhi igesi ephumayo iphinde icutshungulwe ngamadivaysi okugeza, amadivaysi okuqoqa uthuli lokuhlunga, njll., futhi iyakhishwa kushimula ngemva kokuhlangabezana nezindinganiso zokuphepha.
Umlotha wokugcina owakheke ngemva kokushiswa kwemfucuza evuthayo cishe uyingxenye eyodwa kwezimbili yomthamo wokuqala, futhi ezinye izinto eziyingozi ezingenakugwenywa ngokuphelele ziphathwa ngokungenabungozi ngezidakamizwa.Umlotha ugcine uthuthelwe e-Osaka Bay ukuyolahlwa khona.
Kunjalo, izimboni zokuhlanza imfucuza ezigxile ekushiseni nazo zinebhizinisi elengeziwe, okuwukukhipha izinsiza eziwusizo zemfucuza enkulu engashi njengamakhabethe ensimbi, omatilasi, namabhayisikili.Kukhona nemishini yokuchoboza emikhulu ehlukahlukene efektri.Ngemva kokuba izinto ezibalwe ngenhla zichotshozwe kahle, ingxenye yensimbi ikhethwa isihlukanisi samagnetic futhi ithengiswe njengesisetshenziswa;kuyilapho iphepha namanikiniki anamathiselwe ensimbi kususwa ngokuhlolwa komoya, futhi Ezinye izingxenye ezivuthayo zithunyelwa kumshini wokushisela umlilo ndawonye.
Ukushisa okukhiqizwa ukushiswa kwemfucuza kusetshenziselwa ukwenza isitimu, esibese sihanjiswa ngamapayipi ezinjinini zokuphehla ugesi.Ukushisa kungahlinzeka ngamanzi ashisayo kanye nokufudumeza amafekthri ngesikhathi esifanayo.Ngo-2011, cishe amathani angu-133,400 emfucumfucu ashiswa lapha, ukuphehlwa kukagesi kwafinyelela ku-19.1 million kwh, ukuthengiswa kukagesi kwaba yizigidi ezingu-2.86 kwh, kanti imali engenayo yafinyelela ku-yen wezigidi ezingu-23.4.
Ngokwemibiko, e-Osaka kuphela, kusenezimboni eziyisi-7 zokulahla imfucuza njengeTaisho.Kulo lonke elase-Japan, ukusebenza kahle kwezimboni eziningi zikamasipala zokushiswa kwemfucuza kubaluleke kakhulu ukugwema izinkinga ezifana “nokuvinjezelwa kukadoti” kanye “nokungcoliswa kwemithombo yamanzi”.
