Coagulants - ndi chiyani ichi? Kodi ndi zimene coagulants ntchito

Kugwiritsa ntchito madzi oyera bwino thanzi ndi anthu chitetezo chokwanira, kupatula akuchira thupi lenilenilo, ntchito nkhokwe yake. Anthu kwa zaka anakakhala pafupi ndi mitsinje ndi nyanja, ntchito magwero amene anapereka moyo ndi chilengedwe. Ambiri otukuka wakale ankadziwa mmene kuyeretsa madzi zosowa za unzika kudutsa izo kupyolera zigawo ya dongo ndi mchenga. M'masiku amenewo, anthu sanagwiritse ntchito coagulants (mankhwala, amene amapangidwa ndi mankhwala yaikulu ya madzi opatsa moyo lero).

Chotero madzi osiyana woyera

Masiku ano amaona kuti, Choncho, anthu ayenera kugwiritsa ntchito m'nyumba zawo mitundu itatu ya madzi:

• ndikupeza madzi kuti wadutsa muyezo angapo coarse kuyeretsa ndi zosefera mwa atsamunda wapadera;
• banja, poyamba anasintha kuteteza lonse lomenyera zipangizo Kutentha ntchito osamba ndi kusamba;
• kumwa, ntchito yokhayo yotumikira ingestion ndi kuphika.

Plain madzi nyumba amapereka m'tawuni dongosolo madzi. Chifukwa chololera kunyumba pambuyo chithandizo ntchito Zosefera yosiyanasiyana structuring wa dongosolo ndipo anazindikira phindu la ena mchere (monga shungite). Komanso, pali coagulants, masaka m'madzi ntchito zapakhomo.

Kodi n'chiyani chikuchitikira madzi asanayambe chitoliro

Asanathetse ndi kusefera opangidwa kuyambirira akhakula mankhwala a madzi anafuna kotunga kachitidwe m'tawuni madzi. Choyamba, muli wapadera msanga kusakaniza madzi ndi coagulant (ndi mankhwala wapadera). Pamene coagulating ndi repulsion electrostatic particles kusungunuka m'madzi yafupika, iwo limodzi. Izi facilitates ndi kufulumizitsa ndi kuyeretsa pa Kuthetsa ndi kusefera.

The ndondomeko mu thanki imodzi ayenera lolimba za chimodzi miniti. Ndi nthawi imeneyi ang'onoang'ono sasamalira chofunika pachilichonse za kusakaniza mankhwala ndi madzi. Pa mogwirizana yaitali akhoza kuswa floccules anapanga (precipitate slipshiesja particles yachilendo). Pambuyo kudutsa akasinja angapo kumene coagulants madzi wothira ndi mtengo pang'onopang'ono mwayamba kufooka, madzi a pansi sedimentation.

ndi mawu wokongola "flocculation" Kodi

Coagulants - ndi mankhwala reagents. Sikuti onse ndi zoipa zinthu anthu akhoza linachokera mu kusefera mwachizolowezi mu nthawi yochepa. Ena mwa iwo ali mu chikhalidwe kusungunuka. Ngati zinyalala alipo mu madzi kapena hydrosols, ndi coagulants kwa madzi mankhwala pa nthawi ya mogwirizana ndi iwo kupanga precipitate insoluble mu mawonekedwe a slurry ndi. The ndondomeko ya mapangidwe particles agglomerated chabwino, ikuluikulu "milu" Ndiyeno flocculation. Kukula kwa particles latsopano kungakhale kwa millimeters angapo.

Kumene, mukhoza kuyeretsa madzi ku zodetsa zosiyanasiyana mwachizolowezi kusefera, koma kudzatenga zaka zingapo, ndi zoona zimafuna madzi tsiku lililonse zedi yaikulu. Ku kuyeretsa ndondomeko tofa okwanira akakhale opanga ndi anawonjezera coagulants. Izi amachepetsa zosafunika kumasulidwa madzi onse a zinthu zoipa 30-45 Mphindi. Ndi anthu mofulumira la mizinda ndi midzi amatha seamlessly ntchito madzi a m'nyumba zawo.

Kodi chimachitika pa mbewu zimbudzi

Mu madzi, ngakhale chimaonekera pa Mwachidule, kawirikawiri lili wambirimbiri zosafunika. Ena mwa iwo ndi zipangizo zotsatirazi:

• gypsum ndi choko;
• mchenga ndi dongo miyala;
• yl ndi zomera;
• pang'ono sungunuka zitsulo hydroxides;
• mabakiteriya,
• kusungunuka mankhwala;
• kuyimitsidwa zosiyanasiyana.

Lolemera yaikulu particles misa mkulu enieni mwachilungamo mofulumira kugwa pansi Mlendo, kwa maminiti 1-2. Mofulumira ndi sedimentation ndondomeko (precipitate mapangidwe) ndi tinthu zabwino, zimene ukhoza kwa zaka ziwiri, madzi Chinawonjezeka coagulants. Izi mankhwala enaake ferric, sulphate aluminiyamu, sulphate chitsulo, gidroksosulfaty hydroxychloride ndi zotayidwa, msanganizo wa chitsulo ndi zotayidwa salt, opacifiers dongo, osiyana flocculating kuyimitsidwa ndi brighteners.

Ayeretsedwe ndi mafotokozedwe a madzi mu dongosolo la Kuthetsa ofukula pa 1 lita imodzi 50 100 ml reagent. Chokulitsidwa ndi glued pamodzi ndi zochita za mankhwala particles colloidal precipitate, zomwe zina mosavuta ankasiyana yothetsa ndi kusefera.
