Kumwa madzi ochokera m'madzi am'nyanja

Kusintha kwanyengo ndikukula kwamsanga kwa mafakitale apadziko lonse ndi ulimi kwapangitsa kuti vuto la kusowa kwa madzi abwino likukulirakulira, ndipo madzi akumwa akuchulukirachulukira, kotero kuti mizinda ina ya m'mphepete mwa nyanja ilinso ndi madzi ochepa. Vuto lamadzi limapangitsa kuti madzi am'madzi amchere amveke kwambiri. Zipangizo za Membrane desalination ndi njira yomwe madzi am'nyanja amalowera kudzera pakakhungu kakang'ono kovutirapo kamene kamapanikizika, mchere wochulukirapo ndi mchere m'madzi am'nyanja amatsekedwa mbali yayikulu ndipo amatayidwa ndi madzi am'nyanja, ndipo madzi abwino akutuluka kuchokera mbali otsika kuthamanga.

Malinga ndi National Bureau of Statistics, kuchuluka kwa madzi amchere ku China anali 2830.6billion cubic metres mu 2015, kuwerengera pafupifupi 6% yamadzi apadziko lonse lapansi, akukhala pachinayi padziko lapansi. Komabe, zopezeka m'madzi abwino za munthu aliyense ndi ma cubic metres 2,300 okha, omwe ndi 1/35 okha padziko lonse lapansi, ndipo kusowa kwa madzi abwino achilengedwe. Ndikukula kwa kutukuka kwamakampani ndi kutukuka kwamatauni, kuipitsa madzi amadzi kumakhala koopsa makamaka chifukwa chamadzi ogwiritsidwa ntchito m'mafakitale komanso zimbudzi zam'mizinda. Kukhalitsa kwamadzi am'madzi akuyembekezeka kukhala njira yayikulu yopezera madzi akumwa abwino kwambiri. Makampani opanga zonyanja zam'madzi ku China amagwiritsa ntchito 2/3 yonse. Kuyambira Disembala 2015, mapulojekiti am'madzi am'madzi okwera 139 adamangidwa mdziko lonselo, okhala ndi matani 1.0265million / tsiku. Madzi ama Industrial amawerengera 63.60%, ndipo malo okhala madzi amakhala 35.67%. Pulojekiti yapadziko lonse lapansi yotsuka madzi makamaka imapereka madzi okhala (60%), ndipo madzi am'mafakitale amangokhala 28%.

Cholinga chofunikira pakupanga ukadaulo wamadzi am'madzi ndikuchepetsa ndalama zogwirira ntchito. Pogwiritsa ntchito ndalama zogwiritsira ntchito, magetsi amagwiritsa ntchito gawo lalikulu kwambiri. Kuchepetsa kugwiritsa ntchito mphamvu zamagetsi ndi njira zothandiza kwambiri pochepetsa kuchepa kwa madzi a m'nyanja.
