Anthu akamaganizira za kasamalidwe ka zinyalala zolimba, mwina amazigwirizanitsa ndi zinyalala zotayidwa m’malo otayirapo kapena kuwotchedwa. Ngakhale kuti ntchito zoterezi zili ndi gawo lofunika kwambiri la ndondomekoyi, pali zinthu zosiyanasiyana zomwe zikukhudzidwa pakupanga njira yabwino kwambiri yoyendetsera zinyalala (ISWM). Mwachitsanzo, njira zamankhwala zimathandizira kuchepetsa kuchuluka kwa zinyalala zolimba komanso kawopsedwe. Masitepe awa atha kuyisintha kukhala mawonekedwe osavuta kutaya. Njira zopangira zinyalala ndi kutaya zinyalala zimasankhidwa ndikugwiritsidwa ntchito potengera mawonekedwe, kapangidwe, ndi kuchuluka kwa zinyalala.
Nazi njira zazikulu zoperekera zinyalala ndi kutaya:
Thermal Chithandizo
Kuchiza zinyalala zotentha kumatanthawuza njira zomwe zimagwiritsa ntchito kutentha kuti zithetse zinyalala. Zotsatirazi ndi zina mwa njira zomwe zimagwiritsidwa ntchito kwambiri pochotsa zinyalala zamafuta:
Kuwotcha ndi imodzi mwazinthu zodziwika bwino zochotsa zinyalala. Njira imeneyi imaphatikizapo kuyaka kwa zinthu zowonongeka pamaso pa mpweya. Njira yochiritsira yotenthayi imagwiritsidwa ntchito ngati njira yopezera mphamvu zamagetsi kapena zotenthetsera. Njirayi ili ndi ubwino wambiri. Amachepetsa msanga kuchuluka kwa zinyalala, amachepetsa mtengo wamayendedwe komanso amachepetsa mpweya woipa wowonjezera kutentha.
Gasification ndi Pyrolysis ndi njira ziwiri zofanana, zonse zomwe zimawola zinyalala za organic powonetsa zinyalala ku mpweya wochepa komanso kutentha kwambiri. Pyrolysis imagwiritsa ntchito mpweya wopanda mpweya pomwe mpweya umalola kuti mpweya ukhale wochepa kwambiri. Gasification ndiyothandiza kwambiri chifukwa imalola njira yoyaka moto kuti ipezenso mphamvu popanda kuwononga mpweya.
Open Burning ndi njira yochotsera zinyalala zomwe zimawononga chilengedwe. Zotenthetsera zomwe zimagwiritsidwa ntchito ngati izi zilibe zida zowongolera kuwononga chilengedwe. Amatulutsa zinthu monga hexachlorobenzene, dioxins, carbon monoxide, particulate matter, volatile organic compounds, polycyclic onunkhira mankhwala, ndi phulusa. Tsoka ilo, njirayi ikugwiritsidwabe ntchito ndi akuluakulu ambiri am'deralo padziko lonse lapansi, chifukwa imapereka njira yotsika mtengo ku zinyalala zolimba.
Zotayira ndi Zotayirapo
Malo otayirako ukhondo amapereka njira yotayira zinyalala yomwe imagwiritsidwa ntchito kwambiri. Malo otayiramo nthakawa amafunidwa kuti athetse kapena kuchepetsa chiwopsezo cha chilengedwe kapena thanzi la anthu chifukwa cha kutaya zinyalala. Masambawa ali momwe malo amagwirira ntchito ngati zotchingira zachilengedwe pakati pa chilengedwe ndi malo otayiramo. Mwachitsanzo, malo otayirapo amatha kukhala ndi dothi ladongo lomwe silimatha kuwononga zinyalala zowopsa kapena lomwe limadziwika ndi kusakhalapo kwa madzi pamwamba pamadzi kapena madzi otsika, zomwe zimalepheretsa kuwonongeka kwa madzi. Kugwiritsa ntchito malo otayirako ukhondo kumapereka chiwopsezo chocheperako paumoyo ndi chilengedwe, koma mtengo wokhazikitsa malo otayiramo oterowo ndi wokwera kwambiri kuposa njira zina zotayira zinyalala.
Zinyalala zoyendetsedwa bwino ndizofanana ndi zotayiramo aukhondo. Zotayirazi zimagwirizana ndi zofunikira zambiri kuti zikhale zaukhondo koma zitha kusowa imodzi kapena ziwiri. Malo otayira oterowo angakhale ndi mphamvu yolinganizidwa bwino koma osalinganiza ma cell. Pakhoza kukhala palibe kapena kuwongolera pang'ono gasi, kusunga mbiri, kapena kuphimba nthawi zonse.
Zotayirapo za bioreactor ndi zotsatira za kafukufuku waposachedwa waukadaulo. Zotayiramo zinyalalazi zimagwiritsa ntchito njira zapamwamba za microbiological kufulumizitsa kuwonongeka kwa zinyalala. Chiwongolero chowongolera ndikuwonjezera kosalekeza kwamadzimadzi kuti mukhale ndi chinyezi chokwanira kuti tizilombo toyambitsa matenda tigayidwe. Madziwo amawonjezedwa pozunguliranso leachate yotayira pansi. Pamene kuchuluka kwa leachate sikukwanira, zinyalala zamadzimadzi monga zinyalala za m'madzi zimagwiritsidwa ntchito.
Bioremediation
Bioremediation imagwiritsa ntchito tizilombo toyambitsa matenda kuti tiphwanye ndikuchotsa zowononga m'nthaka kapena madzi oipitsidwa. Nthawi zambiri amagwiritsidwa ntchito poyeretsa mafuta otayira, madzi otayira m'mafakitale, ndi mitundu ina ya kuipitsa.Zofala m'malo oipitsidwa ndi mitundu ina ya zinyalala zowopsa.
Kompositi ndi njira ina yomwe imagwiritsidwa ntchito kwambiri pakutaya zinyalala kapena njira yochizira yomwe imayendetsedwa ndi kuwonongeka kwa zinyalala za organic pogwiritsa ntchito tizilombo tating'onoting'ono tokhala ndi msana ndi tizilombo tating'onoting'ono. Njira zodziwika bwino zopangira manyowa ndi monga kompositi ya static pile, vermin-composting, windrow composting ndi in-vessel composting.
Anaerobic Digestion imagwiritsanso ntchito njira zachilengedwe kuti ziwononge zinthu zachilengedwe. Anaerobic Digestion, komabe, amagwiritsa ntchito malo opanda mpweya ndi mabakiteriya kuti awole zinyalala zomwe kompositi imayenera kukhala ndi mpweya kuti tizilombo toyambitsa matenda tizikula.
M'pofunika kuganizira za makhalidwe a zinyalala, malamulo oyendetsera chilengedwe, ndi mmene zinthu zilili m'deralo posankha njira yoyenera yoperekera zinyalala ndi kutaya. Njira zophatikizira zowononga zinyalala zomwe zimaphatikiza njira zingapo nthawi zambiri zimagwiritsidwa ntchito kuthana ndi zinyalala zosiyanasiyana mogwira mtima. Kuonjezera apo, kuzindikira kwa anthu ndi kutenga nawo mbali pa ntchito zochepetsera zinyalala ndi zobwezeretsanso zimagwira ntchito yofunika kwambiri pakuwongolera zinyalala mokhazikika.
