Kuti mutulutse kapena kugwiritsanso ntchito Sewage pambuyo pa Kukonza, mankhwala osiyanasiyana ayenera kugwiritsidwa ntchito mu ndondomeko ya Kukonza Sewage. Masiku ano,Ogulitsa PAM (Polyacrylamide)adzakuuzani za mankhwala ophera tizilombo toyambitsa matenda:
Flocculant: Nthawi zina imatchedwanso coagulant, ingagwiritsidwe ntchito ngati njira yolimbikitsira kulekanitsa kwa solid-liquid, ndipo ingagwiritsidwe ntchito mu thanki yoyamba yokhazikika, thanki yachiwiri yokhazikika, thanki yoyandama, chithandizo chachitatu kapena chithandizo chapamwamba ndi maulalo ena a njira.
Ma Flocculant amagwiritsidwa ntchito ngati njira yolimbikitsira kulekanitsa madzi olimba ndi olimba m'munda wa kukonza zimbudzi. Angagwiritsidwe ntchito kulimbitsa kutayidwa kwa zimbudzi koyamba, kukonza kuyandama ndi kutayidwa kwa zimbudzi pambuyo pa ntchito yoyambitsa matope, komanso angagwiritsidwe ntchito pokonza zimbudzi zitatu kapena kukonza zimbudzi zapamwamba. Akagwiritsidwa ntchito pokonza zimbudzi zisanathe madzi ambiri, ma flocculant ndi ma coagulant amakhala ma sludge conditioner kapena ma dehydrating agents.
Pogwiritsa ntchito ma flocculant achikhalidwe, njira yowonjezera ma coagulant aid ingagwiritsidwe ntchito kukulitsa mphamvu ya flocculant. Mwachitsanzo, kugwiritsa ntchito activated silicic acid ngati coagulant aid ya ma inorganic flocculant monga ferrous sulfate ndi aluminium sulfate ndikuwonjezera motsatizana kungapangitse flocculant yabwino. Chifukwa chake, malinga ndi mawu a layman, inorganic polymer flocculant IPF imakonzedwa pophatikiza coagulant aid ndi flocculant kenako ndikuwonjezeredwa pamodzi kuti ntchito ya wogwiritsa ntchito ikhale yosavuta.
Chithandizo cha coagulation nthawi zambiri chimayikidwa patsogolo pa malo olekanitsa madzi olimba, ndipo pamodzi ndi malo olekanitsa, chimatha kuchotsa bwino zinthu zolimba zomwe zimapachikidwa ndi zinthu za colloidal zokhala ndi tinthu tating'onoting'ono ta 1nm mpaka 100μm m'madzi osaphika, kuchepetsa kutayikira kwa madzi otuluka ndi CODCr, ndipo chingagwiritsidwe ntchito pochiza njira zotsukira zinyalala. Chithandizo, chithandizo chapamwamba, chingagwiritsidwenso ntchito pochiza matope otsala. Chithandizo cha coagulation chingathenso kuchotsa bwino tizilombo toyambitsa matenda ndi mabakiteriya opatsirana m'madzi, ndikuchotsa mafuta osungunuka, chroma, ma ayoni achitsulo cholemera ndi zoipitsa zina m'madzi otayira zinyalala. Kuchuluka kwa phosphorous yomwe ili m'madzi otayira zinyalala kumatha kufika pa 90% pamene coagulation sedimentation ikugwiritsidwa ntchito pochiza phosphorous. ~95%, ndiyo njira yotsika mtengo komanso yothandiza kwambiri yochotsera phosphorous.
Pokonza zimbudzi, zinthu zina zidzagwiritsidwa ntchito. Masiku ano,Wopanga PAManayambitsa chimodzi mwa izo. Kodi mukumvetsabe? Samalani Yuncang ndipo yankhani zambiri zokhudza kuyeretsa zinyalala!
