Chifukwa cha madzi, pali moyo padziko lathuli. Zaka mazana awiri zapitazo, zinali zotheka kumwa madzi kuchokera mthupi lililonse lamadzi popanda kuwopa thanzi. Koma lero, madzi omwe amasonkhanitsidwa m'mitsinje kapena m'nyanja sangathe kumwa popanda chithandizo, chifukwa madzi a World Ocean ndiodetsedwa kwambiri. Musanagwiritse ntchito madzi, muyenera kuchotsa zinthu zovulaza.
Kuyeretsa madzi kunyumba
Madzi omwe amayenda kuchokera kumadzi m'nyumba mwathu amadutsa magawo angapo a kuyeretsa. Pazolinga zapakhomo, ndiyabwino, koma kuphika ndi kumwa, madziwo ayenera kuyeretsedwa. Njira zachikhalidwe ndikutentha, kukhazikika, kuzizira. Izi ndi njira zotsika mtengo kwambiri zomwe aliyense angathe kuchita kunyumba.
Mu labotale, pofufuza madzi owiritsa, zidapezeka kuti mpweya umasokonekera, umakhala "wakufa" komanso wopanda ntchito m'thupi. Komanso, zinthu zofunikira zimachoka m'mapangidwe ake, ndipo mabakiteriya ena ndi ma virus amatha kukhalabe m'madzi ngakhale atawira. Kugwiritsa ntchito madzi owiritsa kwa nthawi yayitali kumatha kubweretsa matenda.
Kuzizira kumabwezeretsanso madzi. Iyi ndiyo njira yabwino kwambiri yoyeretsera madzi, popeza mankhwala okhala ndi klorini amachotsedwa pamapangidwe ake. Koma njirayi ndi yovuta kwambiri ndipo mawonekedwe ena ayenera kuwonedwa. Njira yothetsera madzi idawonetsa kusachita bwino kwenikweni. Zotsatira zake, gawo lina la klorini limachokamo, pomwe zinthu zina zoyipa zimatsalira.
Kuyeretsa madzi pogwiritsa ntchito zida zowonjezera
Pali njira zingapo zoyeretsera madzi pogwiritsa ntchito zosefera ndi njira zingapo zoyeretsera:
- 1. Kuyeretsa kwachilengedwe kumachitika pogwiritsa ntchito mabakiteriya omwe amadya zinyalala zachilengedwe, amachepetsa kuipitsa madzi
- 2. Mawotchi. Poyeretsa, zosefera zimagwiritsidwa ntchito, monga magalasi ndi mchenga, slags, ndi zina zotero, pafupifupi 70% yamadzi atha kutsukidwa
- 3. Zachilengedwe. Makutidwe ndi okosijeni ndi evaporation, coagulation ndi electrolysis ntchito, chifukwa cha zinthu poizoni amachotsedwa
- 4. Kuyeretsa kwamankhwala kumachitika chifukwa cha kuwonjezera kwama reagents monga soda, sulfuric acid, ammonia. Pafupifupi 95% ya zonyansa zoyipa zimachotsedwa
- 5. kusefera. Amagwiritsa ntchito zosefera zoyeserera kaboni. Kusinthana kwa Ion kumachotsa zitsulo zolemera. Kusefera kwa ultraviolet kumachotsa mabakiteriya ndi ma virus
Palinso njira zina zoyeretsera madzi. Izi ndizosungunula ndikusintha osmosis, komanso kufewetsa madzi. M'mikhalidwe yamakono kunyumba, nthawi zambiri anthu amagwiritsa ntchito zosefera poyeretsa ndi kufewetsa madzi.
