Kuchinja kwemamiriro ekunze uye kukurumidza kusimukira kweindasitiri yepasirese nekurima kwakaita kuti dambudziko rekushaikwa kwemvura yakachena riwedzere, uye kupihwa kwemvura yakachena kuri kuramba kuchiwedzera, zvekuti mamwe maguta emahombekombe ari kuperevedzawo mvura.Dambudziko remvura rinounza kudiwa kusati kwamboitika kwekubvisa munyu mugungwa.Membrane desalination equipment inzira iyo mvura yegungwa inopinda nepakati pe semi-permeable spiral membrane pasi pekumanikidzwa, iyo yakawandisa munyu nemaminerari mumvura yegungwa inovharika padivi rekumanikidza uye inobuditswa nemvura yegungwa yakanyura, uye mvura yakachena iri kubuda. kubva kudivi repasi rekumanikidza.

Sekureva kweNational Bureau of Statistics, huwandu hwemvura yakachena muChina hwaive 2830.6billion cubic metres muna 2015, zvichitora chikamu che6% chezviwanikwa zvemvura pasi rose, iri pachinhanho chechina pasi rose.Zvisinei, zviwanikwa zvemvura yakachena pamunhu zvinongova 2,300 cubic metres, inova 1/35 chete yeavhareji yenyika, uye kune kushomeka kwezviwanikwa zvemvura yakachena.Nekukwidziridza kwemaindasitiri uye kuvandudzwa kwemadhorobha, kusvibiswa kwemvura yakachena kwakakomba zvakanyanya nekuda kwemvura yetsvina yemaindasitiri uye tsvina yemumadhorobha.Kubviswa kwemunyu kwemvura yegungwa kunotarisirwa kuve gwara guru rekuwedzera mvura yekunwa yemhando yepamusoro.Indasitiri yekuChina yekuchenesa mvura yegungwa inoshandisa maakaundi e2/3 yehuwandu.Kubva muna Zvita 2015, mapurojekiti ekuchenesa mvura yegungwa 139 akavakwa munyika yese, aine huwandu hwematani 1.0265million / zuva.Mvura yemaindasitiri inoita 63.60%, uye mvura yekugara inotora 35.67%.Iyo yepasi rose desalination project inonyanya kushandisa mvura yekugara (60%), uye mvura yemumaindasitiri inongoverengera 28%.

Chinangwa chakakosha chekuvandudza tekinoroji yekubvisa mvura yegungwa kudzikisa mari yekushandisa.Mukuumbwa kwemari yekushandisa, kushandiswa kwemagetsi kunotora chikamu chikuru.Kuderedza kushandiswa kwesimba ndiyo inonyanya kushanda nzira yekudzikisa mari yekubvisa mvura yegungwa.
