Chifukwa chiyani?Sankhani Ife

kulemera kwapang'onopang'ono, kusamalira kosavuta, kulimba kwa zomangamanga, kupita patsogolo mwachangu, kungapulumutse ndalama zomanga:
Kachulukidwe wa chitoliro cha PVC-U ndi pafupifupi 1400kg/m3, yomwe ndi 1/5 yokha ya chitoliro chachitsulo ndi 1/3 ya chitoliro cha konkire, ndipo mtengo womanga ukhoza kuchepetsedwa ndi 30% -50% poyerekeza ndi chitoliro chachikhalidwe.

Zigawo zapakhomo za nanofiltration membrane zimapereka maubwino odabwitsa. Amakhala ndi madzi okwera - kuthamanga kwamadzi pansi pa kupanikizika kochepa, kuonetsetsa kuti madzi akuyenda bwino. Ndi mphamvu zowononga - kuchotsa, amatha kuthetsa macromolecular organics, heavy metal, ndi divalent salt. Zigawozi ndizokwera mtengo - zogwira ntchito, zoyenera kugwiritsa ntchito zosiyanasiyana kuphatikiza zoperekera madzi kusukulu, ndipo zimadziwika chifukwa chodalirika.

Zida zophatikizira zanzeru zakunyumba zonyansa zili ndi ntchito zochotsa nayitrogeni ndi phosphorous. Mwa kuphatikiza ukadaulo wolekanitsa wa membrane ndi njira yolumikizira makutidwe ndi okosijeni, komanso kugwiritsa ntchito kuwongolera mwanzeru, dongosololi limakwaniritsa magwiridwe antchito osayendetsedwa ndi kasamalidwe kanzeru. Ndizophatikizana kwambiri, zanzeru komanso zodalirika ndipo zimatha kukhazikitsidwa bwino pansi kapena kukwiriridwa pansi. Ubwino wa madzi opangidwa ndi wokhazikika ndipo ukhoza kukwaniritsa mlingo woyamba wa A.

Ukadaulo wa kusefera kwa membrane wolekanitsa ndiukadaulo wapamwamba kwambiri wolekanitsa womwe wapangidwa zaka zaposachedwa; zochokera maselo kapena tinthu kukula, ndi zazikulu mtanda-otaya kusefera luso ntchito kuthamanga monga mphamvu kusunga dongosolo kuthamanga.

Zida zochotsera mchere m'madzi a m'nyanja ndi zida zomwe zimagwiritsidwa ntchito makamaka pochotsa mchere m'madzi am'nyanja. Kuchotsa mchere m'madzi a m'nyanja makamaka kumagwiritsa ntchito njira ziwiri zochotsera mchere m'madzi a m'nyanja, zomwe ndi njira ya distillation ndi reverse osmosis.

Chida chofewetsa madzi cha boiler ndi chipangizo chopangira madzi chopangira madzi owiritsa, chomwe chimachotsa ma ion a calcium ndi magnesium m'madzi osaphika komanso zinthu zomwe zimayambitsa boiler yayitali.

Njira zazikulu zochizira zosindikizira ndi kudaya madzi onyansa ndi njira zakuthupi, zamankhwala ndi ma electrolysis. Njira zamankhwala ndi zakuthupi nthawi zambiri zimasakanizidwa kuti zitheke bwino. Mu njira yakuthupi, yomwe imagwiritsidwa ntchito kwambiri ndi adsorption, ndipo njira yamankhwala ndiyo makamaka coagulation ndi okosijeni.

Pogwiritsa ntchito mfundo ya reverse osmosis, zida za reverse osmosis ndi zida zomwe zimagwiritsa ntchito ukadaulo wolekanitsa nembanemba kuti zithandizire njira yodutsa nembanemba yam'mbuyo ya osmosis ndikulekanitsa zosungunulira zothetsera.
