Kuwotcha zinyalala kungakhalenso chinthu chabwino

Kuwotcha zinyalala, m’maso mwa anthu ambiri, kumawoneka kuti kumatulutsa kuipitsidwa kwachiŵiri, ndipo dioxin yopangidwa mmenemo yokha imapangitsa anthu kulankhula za izo.Komabe, m’maiko otsogola kwambiri otaya zinyalala monga Germany ndi Japan, kuwotcha ndiye chinthu chachikulu, ngakhalenso njira yaikulu yotayira zinyalala.M'mayikowa, malo otenthetsera zinyalala ambiri sanakanidwe ndi anthu.Chifukwa chiyani izi?

Gwirani ntchito molimbika pa chithandizo chosavulaza
Mtolankhaniyo posachedwapa anayendera malo ochitirapo zinyalala a Taisho omwe ali pansi pa Environmental Bureau ya mumzinda wa Osaka ku Japan.Kuno sikungochepetsa kwambiri kuchuluka kwa Zinyalala mwa kuyatsa zoyaka, komanso kumagwiritsa ntchito bwino kutentha kwa zinyalala kuti apange magetsi komanso kupereka mphamvu ya kutentha, yomwe inganene kuti imagwira ntchito zingapo.

Zofunikira pakuwotchera zinyalala kuti zigwire ntchito zingapo pa sitiroko imodzi ziyenera kukhala chitetezo komanso kutsika kwa kuipitsa.Mtolankhaniyo adawona m'dera lafakitale la Dazheng Waste Treatment Plant kuti shaft yayikulu ya Waste ndi 40 metres kuya ndipo imakhala ndi mphamvu ya 8,000 cubic metres, yomwe imatha kusunga matani 2,400 a Zinyalala.Ogwira ntchito amawongolera patali crane kuseri kwa khoma lotchinga magalasi pamwamba, ndipo amatha kutenga matani 3 a zinyalala nthawi imodzi ndikutumiza ku chotenthetsera.

Ngakhale pali Zinyalala zambiri, palibe fungo lonyansa m'dera la fakitale.Izi ndichifukwa choti fungo lopangidwa ndi Zinyalala limachotsedwa ndi chotenthetsera chotenthetsera mpaka 150 mpaka 200 digiri Celsius ndi chotenthetsera mpweya, kenako chimatumizidwa ku chowotcha.Chifukwa cha kutentha kwambiri mu ng'anjo, zinthu zonunkhiza zonse zimawola.

Pofuna kupewa kupanga ma carcinogen dioxins panthawi yoyaka, chotenthetseracho chimagwiritsa ntchito kutentha kwapakati pa 850 mpaka 950 digiri Celsius kuti chiwotchere Zinyalalazo.Kudzera pazenera loyang'anira, ogwira ntchito amatha kuyang'ana momwe zinthu ziliri mkati mwa chowotchera munthawi yeniyeni.

Fumbi lomwe limapangidwa panthawi yowotcha zinyalala limatengedwa ndi wotolera fumbi lamagetsi, ndipo mpweya wotulutsa mpweya umakonzedwanso ndi zida zotsuka, zida zosonkhanitsira fumbi, ndi zina zambiri, ndipo zimatulutsidwa mu chimney mutakwaniritsa miyezo yachitetezo.

Phulusa lomaliza lomwe limapangidwa pambuyo poyaka zinyalala zoyaka ndi pafupifupi gawo limodzi mwa magawo makumi awiri a voliyumu yoyambirira, ndipo zinthu zina zovulaza zomwe sizingapewedwe kwathunthu zimathandizidwa popanda vuto ndi mankhwala.Pomalizira pake phulusalo linasamutsidwa kupita ku Osaka Bay kuti akatayidwe.

Zowona, malo opangira zinyalala omwe amayang'ana kwambiri pakuwotcha alinso ndi bizinesi yowonjezereka, yomwe ndi yochotsa zinthu zofunikira pazinyalala zazikulu zosayaka monga makabati achitsulo, matiresi, ndi njinga.Palinso zida zosiyanasiyana zazikulu zophwanyira fakitale.Zinthu zomwe tazitchulazi zitaphwanyidwa bwino, gawo lachitsulo limasankhidwa ndi olekanitsa maginito ndikugulitsidwa ngati gwero;pamene mapepala ndi nsanza zomwe zimagwirizanitsidwa ndi zitsulo zimachotsedwa ndi kuyang'ana mphepo, ndipo Zigawo Zina zoyaka zimatumizidwa ku chowotchera pamodzi.

Kutentha kochokera ku zinyalala kumagwiritsidwa ntchito popanga nthunzi, yomwe imatumizidwa ku makina opangira magetsi.Kutentha kungaperekenso madzi otentha ndi kutentha kwa mafakitale nthawi imodzi.Mu 2011, pafupifupi matani 133,400 a Zinyalala adatenthedwa pano, mphamvu yopangira magetsi idafika pa 19.1 miliyoni kwh, malonda amagetsi anali 2.86 miliyoni kwh, ndipo ndalama zomwe adapeza zidafika 23.4 miliyoni yen.

Malinga ndi malipoti, ku Osaka kokha, pali malo opangira zinyalala 7 ngati Taisho.M'dziko lonse la Japan, ntchito yabwino ya mafakitale ambiri otenthetsera zinyalala ndi yofunika kwambiri kuti tipewe mavuto monga "Kuzingidwa kwa Zinyalala" ndi "kuipitsa malo otayirako madzi".
