Polyaluminium Chloride(PAC) ndi wamba inorganic polima coagulant. Maonekedwe ake nthawi zambiri amawoneka ngati ufa wachikasu kapena woyera. Ili ndi ubwino wa coagulation effect, mlingo wochepa komanso ntchito yosavuta. Polyaluminiyamu Chloride chimagwiritsidwa ntchito m'munda mankhwala madzi kuchotsa zolimba inaimitsidwa, mitundu, fungo ndi ayoni zitsulo, etc., ndipo angathe kuyeretsa bwino madzi. Kuti zitsimikizire kuti zimagwira ntchito bwino komanso zotetezeka pakagwiritsidwe ntchito, njira zoyenera zogwiritsira ntchito ndi zosungira ziyenera kutsatiridwa.
Kugwiritsa ntchito PAC
Pali njira ziwiri zazikulu zogwiritsira ntchito Polyaluminium Chloride. Imodzi ndikuyika mankhwalawo m'madzi kuti ayeretsedwe, ndipo inayo ndikuyikonza kuti ikhale yankho ndikuigwiritsa ntchito.
Kuphatikiza kwachindunji: Onjezani Polyaluminium Chloride mwachindunji m'madzi oti muthiridwe, ndikuwonjezeranso molingana ndi mulingo woyenera wopezeka pakuyezetsa. Mwachitsanzo, pochiritsa madzi amtsinje, zolimba za Polyaluminium Chloride zitha kuwonjezeredwa mwachindunji.
Konzani yankho: Konzani Polyaluminium Chloride kukhala yankho molingana ndi gawo linalake, ndiyeno onjezerani m'madzi oti muyeretsedwe. Pokonzekera yankho, choyamba tenthetsani madzi kuti awira, kenaka yikani Polyaluminium Chloride pang'onopang'ono ndikugwedeza mosalekeza mpaka Polyaluminium Chloride itasungunuka kwathunthu. Njira yothetsera vutoli iyenera kugwiritsidwa ntchito mkati mwa maola 24. Ngakhale zimawonjezera njira imodzi, zotsatira zake zimakhala bwino.
Kusamalitsa
Jar test:Pali zinthu zambiri zosadziwika m'zimbudzi. Kuti mudziwe mlingo wa flocculant, m'pofunika kudziwa chitsanzo chabwino cha PAM ndi mlingo woyenera wa mankhwala kudzera muyeso la mtsuko.
Sinthani pH mtengo:Mukamagwiritsa ntchito Polyaluminium Chloride, pH yamadzi yamadzi iyenera kuyang'aniridwa. Pamadzi otayira acidic, zinthu za alkaline ziyenera kuwonjezeredwa kuti zisinthe mtengo wa PH kukhala woyenerera; pamadzi otayidwa amchere, zinthu za asidi ziyenera kuwonjezeredwa kuti zisinthe mtengo wa PH kukhala woyenerera. Posintha mtengo wa pH, mphamvu ya coagulation ya Polyaluminium Chloride ikhoza kuchitidwa bwino.
Kusakaniza ndi Kusakaniza:Kusakaniza koyenera ndi kusonkhezera kuyenera kuchitika pogwiritsa ntchito Polyaluminium Chloride. Kupyolera mu makina osonkhezera kapena mpweya, Polyaluminium Chloride imalumikizidwa kwathunthu ndi zolimba zoyimitsidwa ndi ma colloids m'madzi kuti apange magulu akuluakulu, omwe amathandizira kukhazikika ndi kusefera. Nthawi yoyenera yosonkhezera nthawi zambiri imakhala mphindi 1-3, ndipo liwiro loyambitsa ndi 10-35 r/min.
Samalani kutentha kwa madzi:Kutentha kwa madzi kumakhudzanso coagulation ya Polyaluminium Chloride. Nthawi zambiri, kutentha kwa madzi kukakhala kotsika, mphamvu ya polyaluminiyamu kolorayidi imachepetsa ndikufooka; pamene kutentha kwa madzi kuli kwakukulu, zotsatira zake zidzawonjezeka. Chifukwa chake, mukamagwiritsa ntchito Polyaluminium Chloride, kutentha koyenera kumayenera kuyendetsedwa molingana ndi mikhalidwe yamadzi.
Dosing motsatizana:Mukamagwiritsa ntchito Polyaluminium Chloride, chidwi chiyenera kulipidwa pakutsata kwa dosing. Nthawi zonse, Polyaluminium Chloride iyenera kuwonjezeredwa kumadzi musanayambe njira zochizira; ngati amagwiritsidwa ntchito pamodzi ndi othandizira ena, kuphatikiza koyenera kuyenera kupangidwa potengera mankhwala ndi njira zogwirira ntchito za wothandizirayo, ndipo muyenera kutsatira mfundo yowonjezera coagulant poyamba ndikuwonjezera thandizo la coagulant.
Njira Yosungira
Zosungidwa zosindikizidwa:Pofuna kupewa kuyamwa kwa chinyezi ndi oxidation, Polyaluminium Chloride iyenera kusungidwa pamalo owuma, ozizira, ndi mpweya wabwino, ndikusunga chidebe chotsekedwa. Panthawi imodzimodziyo, pewani kusakaniza ndi zinthu zapoizoni ndi zovulaza kuti mupewe ngozi.
Kuletsa chinyezi komanso anti-caking:Polyaluminium Chloride imatenga chinyezi mosavuta ndipo imatha kuphatikizika pambuyo posungira kwa nthawi yayitali, zomwe zimakhudza kugwiritsa ntchito. Choncho, tcheru chiyenera kuperekedwa ku chinyezi-kutsimikizira pa nthawi yosungirako kuti musagwirizane ndi nthaka. Zida zoteteza chinyezi zitha kugwiritsidwa ntchito kudzipatula. Pa nthawi yomweyo, m'pofunika nthawi zonse kufufuza ngati mankhwala ndi agglomerated. Ngati agglomeration ipezeka, iyenera kuthetsedwa munthawi yake.
Kutali ndi kutentha:Kukhala padzuwa kwa nthawi yayitali kungayambitse Polyaluminium Chloride kugwa ndikusokoneza magwiridwe antchito; crystallization akhoza kuchitika pa kutentha otsika. Choncho, kuwala kwa dzuwa ndi kutentha kwakukulu kuyenera kupewedwa. Panthawi imodzimodziyo, sungani zizindikiro zochenjeza za chitetezo zikuwonekera bwino m'malo osungiramo zinthu.
Kuyendera pafupipafupi:Kusungirako kwa Polyaluminium Chloride kuyenera kuyang'aniridwa pafupipafupi. Ngati agglomeration, kusintha kwamtundu, ndi zina zotero, ziyenera kuthetsedwa mwamsanga; panthawi imodzimodziyo, khalidwe la mankhwala liyenera kuyesedwa nthawi zonse kuti litsimikizire kuti likugwira ntchito mokhazikika.
Tsatirani malamulo achitetezo:Pakusungirako, muyenera kutsatira malamulo otetezeka otetezedwa ndikuvala zovala zodzitchinjiriza, magolovesi ndi zida zina zodzitetezera; nthawi yomweyo, sungani zizindikiro zochenjeza zachitetezo pamalo osungiramo zikuwonekera bwino ndipo tsatirani malamulo okhudzana ndi chitetezo kuti mupewe ngozi monga kudya mwangozi kapena kukhudza mwangozi.
Polyaluminium chloride imagwiritsidwa ntchito kwambiriFlocculant mu Water Treatment. Kuti zitsimikizire kuti zimagwira ntchito bwino komanso zotetezeka, ndikofunikira kutsatira kagwiritsidwe ntchito moyenera ndikusunga. Potsatira malangizowa, mutha kukulitsa mapindu a PAC mumtsinje wamadzi
