Kune akawanda marudzi emaflocculants, ayo anogona kukamurwa kuita mapoka maviri, imwe inorganic flocculants uye imwe ndeye organic flocculants.
(1) Inorganic flocculants: inosanganisira mhando mbiri dzesimbi munyu, iron munyu uye aruminiyamu munyu, pamwe neinorganic polymer flocculants senge.polyaluminum chloride. Anowanzo shandiswa ndeaya: ferric chloride, ferrous sulfate, ferric sulfate, aluminium sulfate (alum), basic aluminium chloride, nezvimwe.
(2) Organic flocculants: kunyanya polymer zvinhu zvakadai polyacrylamide. Nekuti mapolymer flocculants ane zvakanakira: diki dosage, kukurumidza sedimentation rate, yakakwirira floc simba, uye kugona kuwedzera kusefa kumhanya, iyo flocculation mhedzisiro inowanda kusvika kumakumi enguva yakakura kupfuura iyo yechinyakare inorganic flocculants, saka parizvino iri kushandiswa zvakanyanya. mumapurojekiti ekuchenesa mvura.
(Nyanzvi yekuchenesa mvura mugadziri-Mvura Yakachena nyika yakachena)
Polymer flocculant - polyacrylamide
The main raw material yepolyacrylamide (PAM kwenguva pfupi)inonzi acrylonitrile. Inosanganiswa nemvura mune imwe chikamu uye inowanikwa kuburikidza ne hydration, kucheneswa, polymerization, kuomesa uye mamwe maitiro.
Mhedziso dzinotevera dzinogona kutorwa kubva pane zvakamboedzwa:
(1) Anionic PAM inokodzera inorganic yakamiswa nyaya ine yakanyanya kusungwa uye yakanaka chaji, pamwe neyakaomeswa yakamiswa zvimedu (0.01 ~ 1mm), uye kwazvakarerekera kana alkaline pH kukosha.
(2) Cationic PAM inokodzera nyaya yakamiswa nechaji isina kunaka uye ine organic matter.
(3) Nonionic PAM inokodzera kupatsanurwa kwezvinhu zvakamiswa musanganiswa organic uye inorganic state, uye mhinduro ine acidic kana kwayakarerekera.
Flocculant kugadzirira
Iyo flocculant inogona kuve yakasimba chikamu kana yakakwira yekumisikidza mvura chikamu. Kana iyi flocculant yakawedzerwa zvakananga kune kumiswa, nekuda kwehupamhi hwayo uye yakaderera kupararira mwero, iyo flocculant haigone kuparadzirwa zvakanaka mukumiswa, zvichiita kuti chikamu cheiyo flocculant isakwanise kutamba flocculation basa, zvichikonzera kuparara kwe flocculant. . Naizvozvo, muvhenganisi wekunyungudutsa unodiwa kubvongodza flocculant uye huwandu hwakakodzera hwemvura kuti isvike kumwe kusungwa, kazhinji isingapfuuri 4 ~ 5g/L, uye dzimwe nguva isingasviki kukosha uku. Mushure mokukurudzira zvakaenzana, inogona kushandiswa. Nguva yekukurudzira inenge 1 ~ 2h.
Mushure mekunge iyo polymer flocculant yagadzirwa, nguva yayo yechokwadi ndeye 2 ~ 3d. Kana iyo mhinduro ikava muchena wemukaka, zvinoreva kuti mhinduro yacho yakashata uye yapera, uye inofanira kumiswa pakarepo.
Iyo amide boka re polyacrylamide inogadzirwa neYixing Cleanwater Chemicals Co., Ltd. inogona kuwirirana nezvinhu zvakawanda, adsorb uye kugadzira hydrogen zvisungo. Zvine huremu hwemamorekuru huremu polyacrylamide inoumba mabhiriji pakati peadsorbed ion, inogadzira flocs, uye inomhanyisa kuyerera kwezvimedu, nekudaro kuzadzisa chinangwa chekupedzisira chekuparadzaniswa kwakasimba-mvura. Kune anionic, cationic uye asiri-ionic marudzi. Panguva imwecheteyo, vatengi vanogonawo kugadzirisa zvigadzirwa zvemhando dzakasiyana
