Polyacrylamide (PAM), nga flocculant ey'omugaso, erina omugaso omunene ogw'okukozesa mu kulongoosa amazzi ag'omusaayi ag'okusika amayinja.

Okunoonyereza kuno kuno kukolebwa okuva mu bintu nga okulonda tekinologiya, enkola y'okukola, n'okulongoosa enkola:

Ng'ekyokulabirako, mu kuyonja amazzi ag'amayinja mu Zhuzhou, PAM ey'ekika kya anionic awamu n'ebintu ebitalina butonde (nga PAC) esobola okufulumya amangu ebitundu ebinene, okwongera ku bungi bw'okusaasaanya emirundi 10 okutuuka ku 15.

Ebintu eby'enjawulo eby'okukozesa cationic PAM

Amazzi agamu ag'amayinja agasaanira galimu ebintu ebikyusa obutonde oba ebintu ebirimu obuzibu. Cationic PAM (ng'obuzito bwa molekyuli obukadde 8 n'omutindo gwa ion ogwa 20%-30%) esobola okwongera ku nkola y'okufulumya okuyita mu kuziyiza amasannyalaze. Embeera emu mu Suzhou eraga nti PAM ey'ekika kya cationic erina engeri ey'amaanyi ey'okujjanjaba ebintu ebiriko obuzito era era erina n'engeri ey'okuyamba ku sipiidi y'okutambula kw'ebyuma ebikozesebwa mu kussa n'okukozesa amazzi ag'omusaayi.

Emiganyulo gy'enkola y'okuteekawo ebintu

Okukozesa awamu starch eyakyusibwa ne PAM (ng'okugatta starch eyakyusibwa ne polyacrylamide mu Webpage 1) kuyinza okukendeeza nnyo ku buzibu. Ng'ekyokulabirako, mu mazzi ag'omusaayi agalina obuzibu bwa 5000 NTU, omuwendo gw'okuggyawo omutindo gw'ekikozesebwa (2 mL ey'omusaayi ogukyusibwa +0.2 g ya PAM) gwatuuka ku 99.3%. Mu ngeri y'emu, okukozesa awamu PAC ne PAM kuyinza okwongera ku bungi bw'okukozesa flocculation era n'okukendeeza ku bbeeyi y'okujjanjaba ebitundu 8%.

II. Ebintu ebikulu eby'enkola n'ebitundu by'emirimu

Okukozesa omutindo n'omuwendo

Anionic PAM: Ekitundu ekiragiddwa kiri 0.2%-0.3%. Bw'ogenda mu mazzi, ssaanya ku sipiidi emu (100-300 rpm) era ofunde ebbugumu ly'amazzi wansi wa 60°C.

Enkola y'ebikozesebwa: Ebintu ebitalina butonde (nga PAC) bisooka okwongerezebwa, nga bigobererwa PAM okukola enkola y'okukozesa "okusooka, oluvannyuma okugatta" 28.

Omutindo gw'enjawulo gwetaaga okumanyizibwa okuyita mu kugezesa kw'ekikopo. Okufuna omuwendo ogusingawo kujja kuleetawo ebitundu byonna okusaasaana.

Okukyusa omutindo gw'amazzi

Omuwendo gwa pH gw'amazzi ag'omusaayi gwetaaga okukyusibwa okutuuka ku kigero ekituufu (ekitera okuba nga si kya butono okutuuka ku kya butono) okusobola okwongera ku nkola ya PAM.

Ku mazzi ag'omusaayi ag'obuzibu obunene (nga 16,000 NTU), omuwendo gwa PAM gulina okwongera (nga 7 mL ey'omusaayi ogukyusibwa +0.7 g ya PAM). 1.

Ebintu eby'omugaso

Enkola ey'amaanyi: Amaanyi g'okusaasaanya gatuuka ku 100-150 mm/min, n'obusobozi bw'okukozesa obunene n'ekitundu ekitono.

Okukwatagana n'obutonde: Kiyamba mu kuddamu okukozesa amazzi ag'omusaayi, kikendeeza ku kukozesa amazzi, era obusaayi busobola okulongoosebwa obutali kabi oluvannyuma lw'okusaasaanya. 26

Okukyusa: Nga kikyusa ekika kya PAM n'enteekateeka y'okugatta, kisobola okukolagana n'amazzi ag'enjawulo (gamba ng'amazzi ag'enjawulo ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'amazzi ag'

Ebizibu n'engeri y'okulongoosaamu

Okukyusa okw'obutonde: Singa amazzi ag'omusaayi galimu ebintu eby'obutonde, enkola z'okusaanyaawo oba ez'okulongoosa eby'obutonde zirina okugatta 35.

Obuzibu bw'okulonda ekikozesebwa mu by'ekika: Kyetaagisa okumanya ekikozesebwa mu by'ekika ekisingayo obulungi nga kigatta n'okugezesa omutindo gw'amazzi (gamba ng'okunoonyereza ku busobozi bwa Zeta) okwewala okwongera mu ngeri ey'obutaba 46

Enkola y'okukozesa: PAM erina okusaanyizibwa okusobola okwewala okusaanyizibwa oba okusaanyizibwa. 36.

Iv. Ebisenge by'Okusaba n'Ebisuubizo by'Okutumbula

Embeera ya bulijjo

Henan Secco Environmental Protection Technology: Ekikozesa PAM ey'obuzito bwa molecule obukadde 8 okulongoosa amazzi ag'amayinja, n'omuwendo gw'okuggyawo ebintu ebinywevu ebisukka mu 95% n'okweyongera kw'omuwendo gw'okukozesa obuggya 40%.

Henan Senoway: Mu kukozesa enkola ya anionic PAM ne PAC compound system mu Zhuzhou Stone Factory, obulungi bw'okuggya amazzi mu mazzi bweyongedde ebitundu 30%

Obusobozi bw'okutumbula

Olw'okunyweza enkola z'okukuuma obutonde bw'ensi, obwetaavu bw'amazzi ag'omusaayi mu makolero g'amayinja bweyongera. Tekinologiya wa PAM, olw'obusobozi bwayo obw'amaanyi n'eby'enfuna, ejja kufuuka ekintu ekikulu. Mu biseera eby'omu maaso, enkola y'okujjanjaba esobola okwongera okulongoosebwa nga tukulaakulanya PAM empya eyakyusibwa (ng'ekika kya amphoteric ionic) 18.

Ekiwandiiko

Polyacrylamide eraga emiganyulo egikulu mu by'ekikugu mu kuyonja amazzi ag'omusaayi ag'okusaala amayinja, naye kyetaagisa okulongoosa enkola y'okulonda n'okukozesa okuyita mu kugezesa awamu n'omutindo gw'amazzi ag'enjawulo. Okukozesa tekinologiya w'okugatta n'okufuga okw'amagezi (gamba ng'okulondoola pH n'obuzibu ku mutimbagano) y'engeri enkulu ey'okukulaakulana mu biseera eby'omu maaso.
