Kushandiswa kwe ultrafiltration membrane tekinoroji mukurapwa kwemvura yekunwa

Nekuenderera mberi kwekufambira mberi kwemaitiro emaguta, huwandu hwevanhu vemumaguta hwave kuwanda, zviwanikwa zvemudhorobha uye mvura yemudzimba zvishoma nezvishoma zvinova chimwe chezvikonzero zvikuru zvekumisa budiriro yemaguta. Nekuwedzera kunoramba kuchiwedzera kwehuwandu hwemaguta, kushandiswa kwemvura zuva nezuva kweguta kunoramba kuchiwedzera, uye zuva nezuva tsvina yemvura yeguta inoratidzawo kuenderera mberi kwekukura. Naizvozvo, maitiro ekuvandudza mwero wekushandiswa kwezviwanikwa zvemvura yemudhorobha uye kuderedza kusvibiswa kwetsvina uye madhiraini rave dambudziko rekutanga kugadziriswa nekukurumidza. Pamusoro pezvo, zviwanikwa zvemvura yakachena zviri kushomeka zvakanyanya uye chido chevanhu chekucheneswa kwemvura chiri kuramba chichikwira. Izvo zvinodikanwa zvinoda kuti zviri mukati mezvinhu zvinokuvadza mumidziyo yemvura, ndiko kuti, kusvibiswa, kuve kwakaderera, izvo zvinoisa pamberi pepamusoro zvinodiwa zvekunatswa kwetsvina uye tekinoroji yekurapa. Ultrafiltration membrane tekinoroji ine yakajairwa physicochemical uye kupatsanurwa maitiro, yakakwirira tembiricha kuramba uye makemikari kuramba, uye yakagadzikana pH. Naizvozvo, ine yakasarudzika mabhenefiti ekurapwa kwemvura yekunwa kwemadhorobha, iyo inogona kunyatso bvisa organic zvinhu, yakamiswa zvimedu uye zvinokuvadza mumvura yekunwa, uye nekuwedzera kuve nechokwadi chekuchengetedzwa kwemvura yekunwa yemumaguta.

Kushandiswa kwe ultrafiltration membrane tekinoroji mumvura yegungwa desalination

Zviwanikwa zvepasi rose zvemvura yakachena zvishoma, asi zviwanikwa zvemvura zvinofukidza inosvika 71% yenzvimbo yese yepasi, kureva kuti, zviwanikwa zvepasi rose zvemvura yemugungwa zvakapfuma kwazvo. Naizvozvo, desalination chiyero chakakosha kugadzirisa kushomeka kwemvura yakachena yevanhu. Nzira yekuchenesa mvura yegungwa inzira yakaoma uye yakareba kwenguva refu. Kuongorora kwenguva refu kunoenderana nekuchenesa zviwanikwa zvemvura yegungwa izvo zvisingakwanisi kushandiswa zvakananga mumidziyo yemvura yakachena inogona kudyiwa zvakananga. Nekukurumidza kukura kwesainzi uye tekinoroji, tekinoroji yekubvisa mvura yegungwa zvishoma nezvishoma yakawedzera uye kuvandudzwa. Semuenzaniso, kushandisa tekinoroji yeelectro-osmosis inogona kuwana nguva imwe chete yekubvisa salination yemvura yegungwa, asi kushandiswa kwesimba kwekubvisa mvura yegungwa kwakakura zvakanyanya. Ultrafiltration membrane tekinoroji ine yakasimba kupatsanurwa maitiro, ayo anogona kunyatso kudzora reverse osmosis dambudziko mukuita kwemvura yegungwa desalination, nekudaro kuvandudza kushanda kwemvura yegungwa kubvisa salination uye kuderedza kushandiswa kwesimba rekubvisa mvura yegungwa. Naizvozvo, ultrafiltration membrane tekinoroji ine yakafara tarisiro yekushandisa mune ramangwana remvura yegungwa desalination kurapwa.

Kushandiswa kweUltrafiltration Membrane Technology muDomestic Sewage

Nekuenderera mberi nekudzika kwemaitiro emaguta, kubuda kwezuva nezuva kwetsvina yemudzimba mumaguta kwakawedzera zvakanyanya. Mashandisirwo etsvina yemudhorobha idambudziko rekukasika kugadziriswa. Sezvatinoziva isu tese, tsvina yemuguta haisi iyo yakawanda yekubuda, asiwo yakapfuma mumafuta zvinhu, organic zvinhu uye huwandu hukuru hwepathogenic microorganisms mumvura yemvura, iyo inounza kutyisidzira kwakakomba kune yakatenderedza nharaunda uye hutano. yevagari. Kana huwandu hukuru hwetsvina yemumba ikaiswa zvakananga munzvimbo yezvakatipoteredza, inosvibisa zvakanyanya nharaunda yakatenderedza guta, saka inofanirwa kuburitswa mushure mekugadziriswa kwetsvina. Ultrafiltration membrane tekinoroji ine yakasimba physicochemical uye yekuparadzanisa maitiro, uye inogona kunyatso kupatsanura organic zvinhu uye mabhakitiriya mumvura. Iyo ultrafiltration membrane tekinoroji inoshandiswa kusefa iyo yakazara phosphorus, yakazara nitrogen, chloride ion, makemikari okisijeni kudiwa, iyo yakazara yakanyungudika ions, nezvimwewo mumvura yemuguta yemuguta, kuitira kuti vese vasangane nemitemo yekutanga yemvura yemudhorobha.
