Udindo wa calcium chloride pakuchotsa zimbudzi

Choyamba, njira ya mankhwala zimbudzi makamaka zikuphatikizapo mankhwala thupi ndi mankhwala mankhwala.Njira yakuthupi ndikugwiritsa ntchito zinthu zosiyanasiyana zosefera ndi kukula kosiyanasiyana kwa pore, kugwiritsa ntchito adsorption kapena njira zotsekereza, zonyansa zomwe zili m'madzi sizikuphatikizidwa, chofunikira kwambiri munjira ya adsorption ndikutengera ndi activated carbon, njira yotsekereza. ndi kudutsa madzi kudzera mu fyuluta zakuthupi, kuti voliyumu yaikulu ya zonyansa sangathe kudutsa, ndiyeno kupeza madzi aukhondo.Kuonjezera apo, njira yakuthupi imaphatikizaponso njira yamvula, yomwe imalola kuti zonyansa zomwe zili ndi gawo laling'ono ziyandame pamwamba pa madzi kuti ziphe nsomba, kapena zonyansa zomwe zimakhala ndi gawo lalikulu pansi pamadzi, ndiyeno kupeza.Njira yamankhwala ndiyo kugwiritsa ntchito mankhwala osiyanasiyana kuti asinthe zonyansa zomwe zili m'madzi kukhala zinthu zomwe sizimavulaza thupi la munthu, kapena zonyansazo zimakhazikika, njira yochizira mankhwala iyenera kugwiritsidwa ntchito kwa nthawi yayitali kuwonjezera alum ku. madzi, mutatha kusonkhanitsa zonyansa m'madzi, voliyumu imakhala yokulirapo, mutha kugwiritsa ntchito njira yosefera kuti muchotse zonyansazo.

Calcium chloride, mankhwala omwe nthawi zambiri amagwiritsidwa ntchito pochotsa zimbudzi, ndi mankhwala osakhazikika omwe ali mchere wopangidwa ndi chlorine ndi calcium, ionic halide.Ma chloride ions amatha kupha madzi, kupha mabakiteriya owopsa, komanso kuchepetsa kawopsedwe ka madzi.Ma ion a calcium amatha kulowa m'malo mwa zitsulo zomwe zili m'madzi, kupatukana ndikupatula ayoni azitsulo zachitsulo, ndikuchotsa mpweya wa ayoni wa calcium, womwe uli ndi mankhwala ophera tizilombo komanso oyeretsa.

Zotsatirazi ndikuyambitsa ntchito yeniyeni ya calcium chloride pakuchotsa zimbudzi:

1. Kashiamu kloridi kusungunuka m'madzi pambuyo pa ayoni kloridi ndi zotsatira za yolera.

2. Ma ion a calcium amatha kusintha ma cations azitsulo m'madzi otayira, makamaka m'madzi otayira omwe ali ndi zitsulo.Pofuna kuchepetsa kuwonongeka kwa zinthu zoopsa kwambiri zazitsulo zazitsulo ku gawo la biochemical, calcium chloride imagwiritsidwa ntchito pokonzekera kuchotsa zinthu zapoizoni ndi zovulaza izi, zomwe zimagwira ntchito yofunika kwambiri.Ngati chinthu ichi chikugwiritsidwa ntchito mu gawo la utsi, ma chloride ayoni amagwira ntchito yophera bakiteriya.Maoni a calcium anapanga calcium hydroxide precipitated ndipo amachotsedwa ndi mvula.

3. PH neutralization ndi chisanadze malamulo a acidic zimbudzi chitoliro network kuwonjezera moyo utumiki wa maukonde chitoliro.

Njira yeniyeni yogwiritsira ntchito: Madzi otayira akasonkhanitsidwa mu thanki yoyendetsera, madzi onyansa amakwezedwa ku thanki ya coagulation ndi mpope wonyamulira.The coagulation thanki lagawidwa mu njira ziwiri za pang'onopang'ono kusanganikirana ndi kudya kusanganikirana, okwana magawo anayi anachita.Mu thanki yosakaniza yofulumira, sodium hydroxide imawonjezeredwa ku mpope wa dosing kuti asinthe PH ya madzi osakanikirana mu thanki mpaka 8, ndipo polyaluminium chloride yosungunuka ndi madzi amawonjezeredwa nthawi yomweyo.Powonjezera flocculant Polyacrylamide mu wosakwiya kusanganikirana thanki, ndi anapanga kashiamu kolorayidi particles coagulate wina ndi mzake kupanga zazikulu granular floc;Pambuyo pa flocculation, madzi otayira amalowa mu thanki ya sedimentation, kupyolera mu kukhazikika kwachilengedwe kuti akwaniritse cholinga cha kulekana kwamadzimadzi olimba, mphamvu yowonongeka inasefukira kuchokera kumtunda wa thanki ya sedimentation, ndiyeno imathamangira mumtsinje wachiwiri wa coagulation.Pambuyo coagulation yachiwiri ndi mpweya mankhwala, madzi amadutsa mu thumba fyuluta ndi adamulowetsa mpweya fyuluta mu asidi-m'munsi neutralization dziwe la eni ake atatha kudziwa Intaneti ma ion fluoride, ndiyeno pH mtengo kusintha ndi kutulutsidwa.Madzi osayenerera amatayidwa mu thanki yoyezera ndipo kenako amachiritsidwa.
