Polyacrylamide(PAM), semushonga unoshandiswa zvakanyanya wepolymer flocculant, unoshandiswa zvakanyanya mumamiriro akasiyana-siyana ekuchenesa tsvina yetsvina. Zvisinei, vashandisi vazhinji vakasangana nekusanzwisisana panguva yekusarudza nekushandisa. Chinyorwa chino chine chinangwa chekuburitsa kusanzwisisana uku uye kupa kunzwisisa kwakakodzera uye mazano.
Kusanzwisisana 1: Kana huremu hwemamorekuru hwakakura, kushanda kweflocculation kwakawedzera.
Pakusarudza polyacrylamide, vanhu vazhinji vanofunga kuti modhi ine huremu hwakakura inofanira kunge iine simba repamusoro re flocculation. Asi kutaura chokwadi, kune mazana emamodheru epolyacrylamide, akakodzera mamiriro akasiyana emhando yemvura. Hunhu hwemvura yakasviba inogadzirwa nemafekitori mumaindasitiri akasiyana hwakasiyana. pH kukosha uye tsvina chaiyo yemhando dzakasiyana dzemvura zvakasiyana zvakanyanya. Dzinogona kunge dzine acidic, alkaline, neutral, kana dzine mafuta, organic matter, ruvara, sediment, nezvimwewo. Saka, zvakaoma kuti mhando imwe chete yepolyacrylamide isangane nezvinodiwa zvese zvekurapa mvura yakasviba. Nzira chaiyo ndeyekutanga kusarudza modhi kuburikidza nekuyedza, wobva waita bvunzo dzemuchina kuti uone chiyero chakakodzera kuti uwane mhedzisiro inoshanda zvakanyanya.
Kusanzwisisana 2: Kana huwandu hwemagadzirirwo akakwira, zviri nani
Pakugadzirira mishonga yepolyacrylamide, vashandisi vazhinji vanotenda kuti kana huwandu hwacho hwakakwira, zvinoita kuti flocculation ive nani. Zvisinei, maonero aya haasi echokwadi. Kutaura zvazviri, huwandu hwePAM configuration hunofanira kusarudzwa zvichienderana nemamiriro chaiwo etsvina uye sludge. Kazhinji, mhinduro dzePAM dzine huwandu hwe0.1%-0.3% dzakakodzera flocculation uye sedimentation, nepo huwandu hwekubvisa sludge mumakanzuru nemaindasitiri huri 0.2%-0.5%. Kana paine tsvina yakawanda mutsvina, huwandu hwePAM hunogona kudiwa kuwedzerwa zvakakodzera. Saka, huwandu hwekugadzirisa hunofanirwa kusarudzwa kuburikidza nekuyedza usati washandisa kuti uve nechokwadi chekushandiswa kwakanakisa.
Kusanzwisisana 3: Kana nguva yekunyunguduka nekukurunga ikareba, zviri nani
Polyacrylamide chinhu chichena chekristaro chinoda kunyungudutswa zvizere kuti chiwane mhedzisiro yakanaka. Vazhinji vanoshandisa vanofunga kuti kana nguva yekunyungudutswa nekukurunga yakareba, zviri nani, asi kutaura chokwadi izvi hazvisizvo. Kana nguva yekukurunga yakareba zvakanyanya, inokonzera kuputsika kwechikamu chePAM molecular chain uye kukanganisa mashandiro e flocculation. Kazhinji, nguva yekunyungudutswa nekukurunga haifanirwe kunge iri pasi pemaminitsi makumi matatu uye inofanira kuwedzerwa zvakakodzera kana tembiricha yakaderera munguva yechando. Kana nguva yekunyungudutswa nekukurunga iri pfupi zvakanyanya, PAM haizonyungudutswi zvizere, izvo zvinozokonzera kutadza kuita flocculation nekukurumidza mutsvina. Naizvozvo, vashandisi vanofanira kuona kuti nguva yekunyungudutswa yakakwana nekukurunga pavanenge vachishandisa kuti vave nechokwadi chekuti PAM inonyungudutswa.
Kusanzwisisana 4: Dhigirii reIonic/Ionic ndiyo chete hwaro hwekusarudza
Sechimwe chezviratidzo zvakakosha zvepolyacrylamide, ionicity inoreva charge yeionic isina kunaka uye yakanaka uye huwandu hwayo hwekuchaja. Vanhu vazhinji vanoteerera zvakanyanya ionicity pavanotenga, vachifunga kuti kana yakakwira zviri nani. Asi kutaura chokwadi, mwero weionicity une chekuita nehukuru hwehuremu hwemamorekuru. Iyo ionicity yakakwira, huremu hwemamorekuru hudiki, uye mutengo wakakwira. Mukusarudza, kuwedzera kune ionicity, zvimwe zvinhu zvinofanirwa kutariswa, zvakaita semamiriro chaiwo emhando yemvura, zvinodiwa kuti flocculation effect, nezvimwewo. Saka, modhi haigone kusarudzwa zvichibva chete padanho reionization. Kuongororwa kwakawanda kunodiwa kuti uone modhi inodiwa.
Semunhuflocculant, polyacrylamide ine basa rakakosha muindasitiri yekuchenesa mvura. Kana uchida kusarudza zvinodiwa newe, ndapota ndibate.
