Sludge Dehydration chikamu chakakosha cheiyo seyaka kurapa maitiro. Chinangwa chayo ndechekubvisa zvinopindira mvura muiyo sludge, kuitira kuti huwandu hwekutsvedza hushoma, uye mari yekubhadhara uye nzvimbo yepasi inoderedzwa. Mune izvi maitiro, kusarudzwa kweFloculantndiyo kiyi, uye polddadmac, seyakakodzeraCationic Polymer Floculant, iri kutamba chiitiko chinowedzera chakakosha.
Chekutanga, isu tinofanirwa kunzwisisa kuumbwa uye zvivakwa zvekutsvedza. Sludge inonyanya kuve yakasimba sediment yakagadzirwa panguva yekukohwa kwesarudzo. Iyo ine zvikamu zvakaoma senge organic marara, mapoka emicrobial, malorganic zvikamu nemakonzo. Iyo yakasimudzirwa solids mune sludge yakapihwa mhosva yekupomedzerwa uye ichidzingira, asi mvura yekuzadza iyo solids inogona kusvika 95% kusvibiswa kwenzvimbo. Naizvozvo, maitiro ekunyatsoita sludge inorova yave iri nyaya yakakosha mumunda wekurapa kwesewge.
Mune sludge dewatering maitiro,Anofamba-famba ekutsvedzachinhu chakakosha kufurira. Iyo Floculant inosungira zvidiki zvidiki mumasango mune yakakura zvimedu kuburikidza nemagetsi, adsorption yekuvhara, etc. Sechigadzirwa chemakemikari chinoshandiswa zvakanyanya mukurapa kwemarara uye sludge dehydration, polydadmac inoita zvakanaka mukutsvedza kwemvura ine simba nekuda kweiyo yakasarudzika molecular chimiro uye kubhadharisa density.
Iyo molecular chimiro chePolydadmac inopa iyo yakakwira mari yekubhadhara uye yakanakisa adsorption zvivakwa. Munguva yekushomeka kwemvura yekushomeka, polydadmac inogona kukurumidza adsorb pamusoro pechikamu chakasarudzika, kuderedza simba rekudzora pakati pemasangano ekusaruramisira, uye kusimudzira kuumbwa kwemari yakakura pakati pezvikamu. Panguva imwecheteyo, maketeni emanyorerwo ePolydadmac anogona zvakare kuumba chimiro chakasarudzika pamwe chete, uye kugadzira mapepa ari nyore kuti ave nyore kuwana, kuti verenga yemvura isadzikiswe kusvika 60-80% kana kunyange kuderera, uye vhoriyamu inogona kuderedzwa ne 75-87%.
Kuenzaniswa neyechinyakare inorganic flyculants, polddadmac ine yakakura smecular uremu uye kubhadharisa llensity, ichipa iyo yakasimba kugona kugona. Pamusoro pe,PolydadmacKuita kwakanaka kwazvo kwekupaza, kuri nyore kushandisa, uye hakuburitse kusvibiswa kwechipiri. PD pacharo haaburitiri sedimimentation sealum, saka huwandu hwekuwedzera sludge hunogona kuderedzwa.Zvakanakira kuita polydadmac tarisiro hurukuro mumunda wekutsvedza.
Iyo molecular chimiro chePolydadmac inopa iyo yakakwira mari yekubhadhara uye yakanakisa adsorption zvivakwa. Mapoka mazhinji emigwagwa pamatanho ayo molecular anogona kuita nemapoka anonioni pamusoro peSludge zvikamu zvekugadzira ziviso, zvichikonzera kushamisika kwakasimba. Iyi adsorption haingobatsire kuderedza kudzikisira pakati pezvikamu, asi zvakare inobatsira kuumba mafuro akakura.
Pamusoro peiyo molecular chimiro uye kubhadharisa zvivakwa zvePolydadmac, yayo yekushambadzira uye dosage inonyanya kukosha zvinhu zvinokanganisa iyo sludge dehydration. Mukati meimwe renji, sekusangana kwePolydadmac anowedzera kana dosi rinowedzera, kuita kwekusvibirira kwekushamisika kunogona kuvandudzwa. Nekudaro, zvakanyanyisa kusungirirwa kana dosage inogona kutungamira kumhedzisiro yemisungo, zvichikonzera kuchengetedzwa kwekodhi, izvo zvinodzikira zvinodzikira kushata. Naizvozvo, mune zvinoshanda zvinoshandiswa, kuongororwa uye kuronga kunoda kuitwa maererano neyakajeka sewage kurapa system uye sludge zvivakwa kuti uone yakakwana polydadadmac constadration uye dosage.
