Kuwonongeka kwa mpweya ndi madzi kudakali m'gulu la zinthu zomwe zikuvutitsa kwambiri padziko lonse lapansi, zomwe zikuyika zachilengedwe zofunika kwambiri, chakudya, komanso chilengedwe chofunikira pamoyo wamunthu.
Kuipitsa madzi kumakonda kumachokera ku ayoni azitsulo zolemera kwambiri, zowononga zowononga zachilengedwe, ndi mabakiteriya—zowononga poizoni, zowononga zochokera m’mafakitale ndi madzi oipa amene sawola mwachibadwa.Nkhaniyi imakulitsidwa ndi kufalikira kwa matupi amadzi komwe kungapangitse mikhalidwe yabwino kuti mabakiteriya ambiri achulukane, kuipitsanso ndi kuwononga kwambiri madzi abwino.
Kuwonongeka kwa mpweya kumapangidwa makamaka ndi ma volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), ndi carbon dioxide (CO).2) - zoipitsa zomwe makamaka zimachokera ku kuyaka kwa mafuta.Zotsatira za CO2monga mpweya wowonjezera kutentha walembedwa kwambiri, ndi kuchuluka kwa CO2kukhudza kwambiri nyengo ya Dziko Lapansi.
Ukadaulo ndi njira zingapo zapangidwa kuti zithandizire kuthana ndi mavutowa, kuphatikiza activated carbon adsorption, ultrafiltration, and advanced oxidation process (AOPs) yomwe cholinga chake ndi kuthana ndi vuto la kuipitsa madzi.
Kuchokera ku VOCs adsorption system, mupeza kuti Columnar activated carbon ndi gawo lofunikira komanso lodziwika bwino lomwe limagwiritsidwa ntchito pamakina ochizira a VOCs ngati media adsorbent yotsika mtengo.
Mpweya wopangidwa ndi mpweya, womwe ukugwiritsidwa ntchito m'mafakitale kuyambira kumapeto kwa nkhondo yoyamba ya padziko lonse, pakati pa zaka za m'ma 1970 unali chisankho chokondedwa cha kuwononga mpweya wa VOCs chifukwa cha kusankha kwake kuchotsa nthunzi kuchokera ku mitsinje ya gasi ngakhale pamaso pa madzi.
Dongosolo lachizolowezi la carbon-bed adsorption — lomwe limadalira kusinthika kwa gulu — litha kukhala njira yabwino yopezera zosungunulira pazachuma.Adsorption imachitika pamene mpweya wosungunulira ukumana ndi bedi la kaboni ndipo umasonkhanitsidwa pa porous activated carbon surface.
Carbon-bed adsorption imagwira ntchito pochotsa zosungunulira pazitsulo zosungunulira pamwamba pa 700 ppmv.Chifukwa cha zofunikira za mpweya wabwino ndi zizindikiro zamoto, machitidwe abwino akhala akusunga zosungunulira zosachepera 25% za malire otsika ophulika (LEL).
