Kusindikiza ndi Kuyika Mankhwala Omwe AmalandiraAmapangidwa makamaka ndikupangidwa kuti asindikize ndi kupaka utoto wamadzi ndi zophweka pakuchepetsa, komanso cod yayikulu, yomwe imatha kuthana ndi mavuto aukadaulo mu kafukufuku wakale ndikuwongolera dongosolo laofesi yam'manja. Kusindikiza ndi kupatsa madzi otayika kumatha kutumizidwa ku muyezo pambuyo pa chithandizo.
Mtengo wamadzi wosindikiza ndi kupatsirana madzi osungunuka amasiyanasiyana kutengera mtundu wa ulusi womwe umagwiritsidwa ntchito ndi ukadaulo wothandizira, ndipo zinthu zoipitsa zimasiyana kwambiri. Kusindikiza ndi Kuyika Madzi Nthawi zambiri kumakhala ndi mawonekedwe ambiri oipitsa, mitundu ingapo, zopweteka komanso zovulaza, komanso zazitali. Nthawi zambiri, mtengo wosindikiza wa kusindikiza ndi utoto wa zinyalala ndi 4-10, CODCR ndi 400-1000mg / l, l, l, ndi ch, ndipo chromality ndi nthawi 100-400.
Koma posindikiza ndi kupatsirana utoto, mitundu ya ulusi womwe wagwiritsidwa ntchito, ndipo kusintha kwaukadaulo kwaukadaulo, mkhalidwe wonyansa udzasintha kwambiri. M'zaka zaposachedwa, chifukwa cha kukula kwa nsalu za fiber, kukhazikika kwa silika ya mafinya, komanso kupititsa patsogolo ukadaulo komanso kumaliza ukadaulo, alkali anzeru a silika opanga (makamaka Phthalates), ndipo zowonjezera zatsopano zayamba kusindikiza. Codcr ndende yachulukanso kuchokera ku mazana a mg / l mpaka kupitilira 2000-3000mg / l, l, ndipo izi zimachepetsa kuchotsa kwa ma codcr oyambira 70%, kapena otsika.
Kuchuluka kwa kumasula manyowa posindikiza ndi kupatsirana madzi a zinyalala ndi ochepa, koma kuchuluka kwa zodetsa ndi zazitali, zomwe zimakhala ndi mitundu yosiyanasiyana, masamba a maberi a firmwa, komanso zowonjezera zosiyanasiyana. Chimbudzi chimakhala ndi mchere wa pH mozungulira 12. Kusandutsa zinyalala ndi wowuma ndi wothandizika waukulu (monga nsalu ya thonje) imakhala yopanda kanthu komanso yokwanira. Chomwe chimasandutsa madzi ndi mowa wa polyvinyl (polva) ngati wogwirizira wamkulu (monga polsister thonje larp yarn) uli ndi code wamkulu ndi wotsika, ndipo osungira madzi otayika ndi osauka.
Kusindikiza ndi kupatsa madzi onyowa kumakhala ndi madzi ambiri owira komanso kuchuluka kwambiri kwa zodetsa, kuphatikizapo ma cellulose, matric, ma batin-kutentha kumakhala ndi mchere wambiri komanso mtundu wa bulauni.
Kusindikiza ndi Kuyika Madzi Oyera Kumakhala ndi kuthiridwa madzi owononga, koma kuwonongeka kwake kumakhala kovuta, komwe kumakhala kofiyira kotsalira, kochepa kwa acetic acid, sodium thiosulpate, etc.
Kusindikiza ndi Kuyika Makina Othandizira Kutayika Madzi otayika ali ndi zinthu zazitali za alkali, ndi Naoh zomwe zidachokera ku 3% mpaka 5%. Zosindikiza zambiri zosindikizira komanso zopangira zimamuchotsa Naoh kudzera mu kutuluka ndi kudera nkhawa, kotero kuti asunthe madzi otayika nthawi zambiri samatulutsidwa. Kugwiritsa ntchito mobwerezabwereza, madzi omaliza obwera pambuyo pake amakhala achibale, okhala ndi brod, ndi ss.
Kuchuluka kwa madzi osungunuka posindikiza ndi utoto ndi waukulu, ndipo mtundu wamadzi umasiyanasiyana malinga ndi utoto womwe umagwiritsidwa ntchito. Ili ndi ma slurries, utoto, zowonjezera, zowonjezera, ndi zina, ndipo nthawi zambiri zimakhala zolimba alkiline ndi mawu achilengedwe. Cod ndi wokwera kwambiri kuposa Bod, ndipo malo ake osauka alibe.
Kuchuluka kwa kusindikiza ndi kupatsa madzi kutaya zinyalala kumakhala kwakukulu. Kuphatikiza pa madzi osungiramo zinyalala kuchokera ku ntchito yosindikiza, imaphatikizaponso sopong ndi kutsuka madzi madzi onyansa mutatha kusindikiza. Kukhazikika kwa zodetsa ndi zazitali, kuphatikizapo kusalala, utoto, zowonjezera, etc., ndi ma dedo ndi ma cod onse ali kumwamba.
Kuchuluka kwa madzi osindikizira ndi kupatsa utoto mankhwala ndi ochepa, omwe ali ndi tchipisi cha mafinya, ma reint, amalima mafuta, ndi ma slor.
Kusindikiza ndi Kuyika Madzi a Alkali Kuchepetsa madzi owononga amapangidwa kuchokera ku kayendedwe ka alkali, makamaka okhala ndi ma hydolys acid ndi ethylee glycol omwe ali ndi 75%. Madzi a Alkaline amachepetsa madzi osangokhala ndi mtengo wapamwamba wa pH (nthawi zambiri> 12), komanso amakhala ndi chidwi chachikulu ndi zinthu zachilengedwe. Codcr mu madzi otayika omwe atulutsidwa kuchokera ku njira yochepetsera alkali amatha kufikira 90000 mg / l. Makina ochulukirapo opanga matope ndi utoto wina ndizovuta kumoyo, ndipo mtundu uwu wa zinyalala ndi wovuta kwambiri komanso wovuta kunyoza madzi otayika.
Zosindikiza ndi kupatsa zida zamadzimadzi zimagwiritsa ntchito ntchito za moyo wa anaerobic ndi aerobic kudya zodetsa madzi mu madzi otayika. Nthawi yomweyo, zopangira zida zopangira zopangidwa ndi tizilombo tambiri tomwe timayimilira komanso timayandama.
Zipangizozo zimakhala ndi nthawi yokhazikika yamadzi, yomwe imakankhira m'madzi kuti apange mawonekedwe a nthawi yayitali. Mukamachiza zinyalala, chimbudzi chimayamba kulowa mu gawo lakumwamba kuchokera pamwamba pa chipangizocho, ndipo olembayo amayamba kukhazikika pamadzi ndikukankhira mayendedwe kuti asunthire chimbudzi. Kuwonongeka komwe kukubwera kumasakaniza kwathunthu ndi kusakaniza koyambirira, kumasinthira kusintha kwa madzi amtundu wa itlet mpaka pamlingo womwe ungathe. Wairtateyo ali ndi ntchito ziwiri zamadzi zotuluka zamadzi ndikuyimitsa madzi, zimapangitsa chimbudzicho mu gawo lozungulira kuti liziyenda pafupipafupi ndikuwonjezera mpweya wosungunuka mu chimbudzi. Chifukwa cha kufalikira mosalekeza ndi kuyenda kwa chimbudzi mu malo owonera, madzi nthawi iliyonse pamalo ali ofooketsa, ndipo kuchuluka ndi katundu ndi katundu wa tizilombo tating'onoting'ono. Chifukwa chake, machitidwe a gawo lililonse la gawo la nyenyezi amakhala ogwirizana. Izi zimawongolera momwe zinthu zonse zimakhalira ndi zinthu zabwino komanso zofanana. Zovuta pang'onopang'ono zimawonongeka pang'onopang'ono ndi tizilombo tating'onoting'ono, ndipo madzi otaya zinyalala amayeretsedwa. Kudziyeretsa kwabwino kumakhala kokulirapo, ndipo zizindikiro zonse zazomwe zimapangitsa kuti pakhale mikhalidwe ya "misa yopanda mphamvu ya zodetsa zoipitsidwa ndi makampani" (GB 4267-92). Malinga ndi zofunikira za makasitomala, malo othandizanso othandiza amatha kuperekedwa kwa ozone wamphamvu mankhwala ochiritsira akumadzi kuti akwaniritse "Madzi a Madzi Amlengalenga
Kusindikiza kophatikizira kumeneku ndi koyenera kuchitira madola ambiri, sing'anga, komanso makina osindikizira, ndikumaliza kuphika madzi onunkhira, kutentha kwa nsalu ndi thonje.
