Ndi kupititsa patsogolo kosalekeza ndi chitukuko cha njira ya sludge yomwe yakhazikitsidwa, kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka ndalamanininininimbombo33joANI3jojojojojojojojobeka0 KAswenijijishonishonishonilisayo0 lilishonishoninji pano_____________________________________________________________________________________________________________________________________ Komabe, pakugwira ntchito kwenikweni kwa mafakitale ochotsa zimbudzi, kuchulukitsa kwa matope kumachitika nthawi zambiri, zomwe zimakhudza kwambiri kuchuluka ndi mtundu wamadzi oyeretsedwa. Chifukwa chake, ndikofunikira kumvetsetsa zomwe zimayambitsa kuchuluka kwa matope ndi njira zofananira nazo kuti muthetseretu pasadakhale.
Kuchuluka kwa matope ndi chimodzi mwazinthu zosazolowereka zomwe zimachitika panthawi yoyendetsa matope. Pazifukwa zina, matope a matope omwe adalowetsedwa amawonongeka, zomwe zimapangitsa kulekanitsa bwino kwamadzi amatope, zolimba zomwe zimayimitsidwa mumatope, ndikuwonongeka kwa njira yochizira. Chodabwitsa ichi nthawi zambiri chimakhudzana ndi kukula ndi kagayidwe kazinthu zazing'ono. Mwachindunji, zikhoza kugawidwa m'magulu awiri: filamentous sludge bulking ndi non-filamentous sludge bulking. Filamentous sludge bulking makamaka amayamba chifukwa cha kukula kwambiri kwa mabakiteriya a filamentous, omwe amachititsa kuti matope azikhala otayirira kwambiri, kuchuluka kwa voliyumu, kuyandama, komanso kuvutikira kwa sedimentation ndi kupatukana, zomwe zimakhudza mtundu wamadzi otayira. Kuchuluka kwa zinyalala zopanda filamentous kumachitika chifukwa cha kuchuluka kwa metabolites (high-viscosity polysaccharides). Chowoneka bwino kwambirichi chimakwirira tizilombo tating'onoting'ono ta sludge, nthawi zambiri ngati mawonekedwe a gel, zomwe zimapangitsa kuti sedimentation ndi magwiridwe antchito a sludge aipire.
1. Zomwe Zimayambitsa Kuchuluka kwa Dothi
Pali zifukwa zambiri zowonjezera matope: zimakhudzidwa ndi zinthu monga kusintha kwa zigawo za madzi zomwe zimakhudzidwa, kusintha kwa pH mtengo, kusintha kwa kutentha, kusintha kwa zakudya, ndi kusintha monga zowononga. Kumayambiriro kwa kukula, chiwerengero cha sludge index (SVI) chidzapitirira kukwera, mawonekedwe a matope adzakhala otayirira ndipo matope ambiri adzayandama, kulekanitsa madzi amatope kudzakhala kosauka, ndipo madzi otayira adzakhala opanda phokoso. . Panthawiyi, chidwi chiyenera kulipidwa ndipo kufufuza kuyenera kuchitidwa mwamsanga kuti mudziwe chomwe chimayambitsa kukula.

2. Njira Zothetsera Kuthetsa Kuchuluka kwa Sludge
Njira zadzidzidzi zimaphatikizapo kulimbikitsa kuwunika kwabwino komanso kutayidwa kwamadzi, kusintha kagwiritsidwe ntchito, kuwonjezera zinthu zopangira mankhwala, kuwonjezera kuchuluka kwa zinyalala zomwe zimatayidwa, komanso kuchepetsa kuchuluka kwa zinyalala:
(1) Yang'anirani nthawi zonse magawo osiyanasiyana pamayendedwe onyansa: monga index ya sludge (SVI), mpweya wosungunuka, pH mtengo, etc.;
(2) Malingana ndi zotsatira zowunikira, sinthani momwe ntchito ikugwirira ntchito monga aeration ndi zowonjezera zowonjezera kuti mupange malo omwe amathandizira kukula kwa tizilombo toyambitsa matenda.
(3) Onjezani mlingo woyenera wa mankhwala, monga flocculants ndi bactericides, kulamulira kukula kwa filamentous mabakiteriya kapena kusintha sedimentation ntchito sludge;
(4) Powonjezera kuchuluka kwa zinyalala zomwe zimatulutsidwa, ndikuchotsa mabakiteriya ochulukirapo a filamentous, zimathandizira kubwezeretsa magwiridwe antchito a matope.
Kupyolera mu njira zomwe tazitchula pamwambapa, vuto la sludge bulking likhoza kuthetsedwa bwino ndipo zotsatira zake ndi mphamvu zogwiritsira ntchito zimbudzi zingathe kutsimikiziridwa.
