Mukurapa kwemvura yetsvina, pH chinhu chakakosha chinopesvedzera kushanda kweFlocculants.Ichi chinyorwa chinotarisa mukukanganisa kwepH, alkalinity, tembiricha, kusachena particle saizi, uye mhando ye flocculant pa flocculation kushanda.
Impact ye pH
Iyo pH yemvura yetsvina yakabatana zvakanyanya nesarudzo, dosage, uye coagulation-sedimentation kunyatsoshanda kwe flocculants.Zvidzidzo zvinoratidza kuti kana pH iri pasi pe4, coagulation inoshanda yakashata zvakanyanya.Izvi zvinogona kunge zviri nekuda kweiyo yakaderera pH inodzikamisa colloidal zvimedu mumvura ine tsvina, zvichiita kuti zviome kuti flocculants inyatso kuabatanidza.Kana iyo pH iri pakati pe 6.5 ne7.5, kushanda kwekubatanidza kunowedzera zvakanyanya nokuti kusagadzikana kwema colloidal particles mune iyi pH range kunowedzera chiito che flocculants.Nekudaro, kana iyo pH yadarika 8, kugona kwekubatanidza kunowedzera zvakanyanya, pamwe nekuti iyo yakakwira pH inoshandura iyo ion chiyero mumvura ine tsvina, ichikanganisa zvakanyanya flocculants.
Kana iyo pH yanyanya kuderera, PAC haigone kuumba zvinobudirira flocs, uye mapoka eanionic eAPAM achave asina kwaakarerekera, zvichiita kuti isashande.Kana iyo pH yanyanya kukwira, PAC inonaya nekukurumidza, zvichikonzera kusashanda zvakanaka, uye CPAM inowanzoita hydrolysis uye inotadza kushanda.
Basa reAlkalinity
Iyo alkalinity yetsvina buffers pH.Kana sewage alkalinity isingakwani, zvinowanzodiwa kuiwedzera nemakemikari akaita seraimu kuchengetedza pH kugadzikana kunosimudzira PAC's best flocculation effect.Sezvineiwo, kana iyo pH yemvura yakanyanya kuwanda, maasidhi angangoda kuwedzerwa kudzikisa pH kusvika kune kwaakarerekera, kuve nechokwadi chekushanda kwe flocculants.
Impact of Temperature
Tembiricha yemvura yakasviba zvakare chinhu chakakosha chinokanganisa kushanda kwe flocculation.Pakudziya kwakadzika, mvura yetsvina inoratidzira yakakwira viscosity, ichideredza kuwanda kwekudhumhana pakati pecolloidal particles uye kusvibiswa mumvura, ichitadzisa kuwirirana kunamatira kwe flocculants.Nokudaro, pasinei nekuwedzera kuyerwa kwema flocculants, flocculation inoramba ichinonoka, zvichiita kuti zvigadziriswe zvigadziriswe uye zvimedu zvakanaka zvakaoma kubvisa pasi pemamiriro ekupisa.
Kufurira kweKusachena Particle Size
Kukura uye kugoverwa kwezvimedu zvetsvina mumvura yetsvina zvinokanganisa zvakanyanya kushanda kwe flocculation.Zvisina-uniform kana kuti diki zvakanyanyisa particle sizes zvinogona kukonzera kusafamba zvakanaka kwe flocculation nekuti twutsvina hudiki hunowanzo kunetsa kuunganidza zvinobudirira kuburikidza ne flocculants.Mumamiriro ezvinhu akadaro, reflux sedimentation kana kuwedzerwa kwehuwandu hwakakodzera hwe flocculant inogona kuwedzera kushanda kwe flocculation.
Kusarudzwa kweFlocculant Type
Kusarudza iyo yakakodzera mhando ye flocculant kwakakosha pakuvandudza kushanda kwemvura yetsvina.Mhando dzakasiyana dzema flocculants, senge inorganic flocculants, polymer flocculants, uye activated silica gel, vane zvakanakira kwavo mumamiriro akasiyana.Semuyenzaniso, kana yakaturikwa yakaoma mumvura yetsvina iripo mucolloidal form, inorganic flocculants inowanzo shanda zvakanyanya.Paunenge uchibata nediki diki kumiswa, kuwedzera kwepolymer flocculants kana activated silica gel se coagulants kungave kuri madikanwa.Muzviitiko zvakawanda, kushandiswa kwakasanganiswa kweinorganic uye polymer flocculants kunogona kuvandudza zvakanyanya flocculation kushanda uye kuwedzera chiyero chekushandisa.
Zvinhu zvakadai se pH kukosha, alkalinity, tembiricha, kusachena chidimbu saizi, uye flocculant mhando yemvura yakasviba zvakabatana zvinokanganisa kushanda kweiyo flocculants mukurapwa kwetsvina.Kunzwisisa kwakadzama uye kutonga kwezvinhu izvi zvakakosha zvikuru pakuvandudza kushanda kwekuchenesa mvura.Isu tiri mutengesi wako akavimbika wemakemikari anoyerera, ane akawanda marudzi eflocculants, anosanganisira PAM, PAC, nezvimwe. Pawebhusaiti yedu yepamutemo unogona kuongorora zviri nyore mhando yedu yezvigadzirwa.Kana uine mibvunzo kana uchida rubatsiro, tapota inzwa wakasununguka kutibata nesu!
