Momwe mungatayire ndikubwezeretsanso mapepala otentha

Pepala lamafuta ndizinthu zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza ogulitsa, mabanki ndi mayendedwe.Zimakutidwa ndi utoto wapadera womwe umasintha mtundu ukatenthedwa, zomwe zimapangitsa kuti zikhale zoyenera kusindikiza ma risiti, zolemba ndi zomata za barcode.Komabe, mapepala otentha sangathe kubwezeretsedwanso pogwiritsa ntchito njira zachikhalidwe zobwezeretsanso mapepala chifukwa cha kukhalapo kwa mankhwala ndi zowononga.Chifukwa chake, njira zapadera zimafunikira kuti zigwire bwino ndikubwezeretsanso mapepala otenthetsera ndikuchepetsa kukhudzidwa kwake pa chilengedwe.M'nkhaniyi, tiwona njira zomwe zimagwira ntchito pokonza ndi kubwezeretsanso mapepala otentha.

Gawo loyamba pakubwezeretsanso ndikusonkhanitsa mapepala omwe agwiritsidwa ntchito.Izi zitha kuchitika kudzera m'njira zosiyanasiyana, monga kuyika nkhokwe zodzipatulira m'masitolo ogulitsa ndi maofesi, kapena kugwira ntchito ndi makampani okonzanso zinthu kuti atole zinyalala zamapepala.Kusiyanitsa koyenera ndikofunikira kuti zitsimikizire kuti pepala lotentha lokha limasonkhanitsidwa osati kusakanikirana ndi mapepala ena.

Akasonkhanitsidwa, pepala lotenthetsera limasamutsidwa kupita kumalo obwezeretsanso komwe limadutsa njira zingapo kuchotsa utoto ndi zonyansa zina.Gawo loyamba mu gawo lokonzekera limatchedwa pulping, pomwe pepala lotenthetsera limasakanizidwa ndi madzi kuti liphwanyidwe kukhala ulusi pawokha.Zimenezi zimathandiza kulekanitsa utoto ndi ulusi wa pepala.

Pambuyo pa pulping, osakaniza amafufuzidwa kuti achotse particles zotsalira zotsalira ndi zonyansa.Kenako madziwo amapangidwa kuti aziyandama, pomwe timatulutsa thovu la mpweya kuti lilekanitse utoto ndi madzi.Utotowo ndi wopepuka ndipo umayandama pamwamba ndipo umadulidwa, pamene madzi oyera amatayidwa.

Chotsatira pakubwezeretsanso ndikuchotsa mankhwala omwe amapezeka pamapepala otentha.Mankhwalawa ndi monga bisphenol A (BPA), omwe amagwira ntchito ngati opangira utoto pamapepala.BPA ndi chosokoneza chodziwika bwino cha endocrine chomwe chimayika chiwopsezo ku thanzi la anthu komanso chilengedwe.Mitundu yosiyanasiyana yaukadaulo, monga activated carbon adsorption ndi ion exchange exchange, ingagwiritsidwe ntchito kuchotsa BPA ndi mankhwala ena m'madzi.

Utoto ndi mankhwala zikachotsedwa bwino m’madzi, madzi oyeretsedwawo akhoza kugwiritsidwanso ntchito kapena kutulutsidwa pambuyo pa chithandizo choyenera.Ulusi wamapepala wotsalira tsopano utha kutayidwa ngati njira zachikhalidwe zobwezeretsanso mapepala.Zamkatimu zimatsukidwa, kuyeretsedwa ndi kuyeretsedwa kuti zikhale zabwino kwambiri zisanagwiritsidwe ntchito popanga mapepala atsopano.

Tiyenera kuzindikira kuti kubwezeretsanso mapepala otentha ndi njira yovuta yomwe imafuna luso lamakono ndi zipangizo.Chifukwa chake, ndikofunikira kuti mabizinesi ndi anthu omwe amagwiritsa ntchito mapepala otenthetsera azigwira ntchito ndi malo ovomerezeka obwezeretsanso kuti awonetsetse kuti akugwira ntchito moyenera ndikubwezeretsanso.

Pomaliza, mapepala otentha, ngakhale amagwiritsidwa ntchito kwambiri, amapereka zovuta zobwezeretsanso chifukwa cha kukhalapo kwa mankhwala ndi zonyansa.Kukonza ndi kubwezeretsanso mapepala otentha kumaphatikizapo njira zingapo, kuphatikizapo pulping, flotation, kuchotsa mankhwala ndi chithandizo cha fiber.Pogwiritsa ntchito njira zoyenera zosonkhanitsira ndikugwira ntchito ndi obwezeretsanso, tikhoza kuchepetsa bwino chilengedwe cha mapepala otentha ndikulimbikitsa njira zoyendetsera zinyalala zokhazikika.
