Kodi PAC ingayendetse bwanji zinyalala zachimbudzi?

Polyaluminium kloride(PAC) ndi coagulant yomwe imagwiritsidwa ntchito kwambiri pochiza madzi oyipa kuti ayendetse tinthu tating'onoting'ono, kuphatikiza tinthu tating'onoting'ono ta zinyalala.Flocculation ndi njira yomwe tinthu tating'onoting'ono m'madzi timaphatikizana kuti tipange tinthu tating'onoting'ono tomwe timatha kuchotsedwa mosavuta m'madzi.

Umu ndi momwe PAC ingagwiritsire ntchito kuyandama zinyalala zamadzi:

Kukonzekera yankho la PAC:PAC nthawi zambiri imaperekedwa mu mawonekedwe amadzimadzi kapena ufa.Gawo loyamba ndikukonzekera yankho la PAC posungunula mawonekedwe a ufa kapena kutsitsa mawonekedwe amadzimadzi m'madzi.Kuchuluka kwa PAC mu yankho kudzadalira zofunikira zenizeni za njira ya chithandizo.

Kusakaniza:ThePACnjira ndiye kusakaniza ndi zimbudzi sludge.Izi zitha kuchitika m'njira zosiyanasiyana malinga ndi kukhazikitsidwa kwa malo opangira chithandizo.Nthawi zambiri, yankho la PAC limawonjezedwa ku sludge mu thanki yosakaniza kapena kudzera mu dosing system.

Coagulation:Njira ya PAC ikasakanikirana ndi matope, imayamba kuchita ngati coagulant.PAC imagwira ntchito pochepetsa milandu yoyipa pazinyalala zomwe zayimitsidwa, kuwalola kuti asonkhane ndikupanga magulu okulirapo.

Flocculation:Pamene sludge PAC amachitira sludge undergoes wofatsa yoyambitsa kapena kusanganikirana, ndi neutralized particles kuyamba kubwera palimodzi kupanga flocs.Ma flocs awa ndi akulu komanso olemera kuposa tinthu tating'ono, zomwe zimapangitsa kuti zikhale zosavuta kukhazikika kapena kupatukana ndi gawo lamadzimadzi.

Kukhazikitsa:Pambuyo pa flocculation, matope amaloledwa kukhazikika mu thanki yokhazikika kapena kuwunikira.Magulu akuluakulu amakhazikika pansi pa thanki mothandizidwa ndi mphamvu yokoka, ndikusiya madzi omveka bwino pamwamba.

Kulekana:Njira yokhazikitsira ikatha, madzi omveka bwino amatha kuchotsedwa kapena kupopera pamwamba pa thanki yokhazikitsira kuti athandizidwe kapena kutulutsa.Dongosolo lokhazikika, lomwe tsopano ndi lolimba komanso locheperako chifukwa cha flocculation, limatha kuchotsedwa pansi pa thanki kuti lizikonzedwanso kapena kutayidwa.

Ndikofunikira kudziwa kuti kuchita bwino kwa PAC muflocculating zimbudzi matopezitha kutengera zinthu zosiyanasiyana monga kuchuluka kwa PAC yogwiritsidwa ntchito, pH ya matope, kutentha, komanso mawonekedwe amatope omwewo.Kukhathamiritsa kwa magawowa kumachitika kudzera mu kuyezetsa kwa labotale ndi kuyesa koyesa kuti mukwaniritse zotsatira zomwe mukufuna.Kuphatikiza apo, kasamalidwe koyenera ndi kayezedwe ka PAC ndikofunikira kuti zitsimikizire kuti zinyalala za zinyalala zotayidwa bwino komanso zotsika mtengo.
