Nekuenderera mberi kwekusimudzira maindasitiri muChina, marudzi ese emvura yetsvina yemaindasitiri ari kuwedzerawo. Mvura yakasviba yakakwira-yakawanda inogadzirwa neindasitiri ichasvibisa miviri yemvura, kuitira kuti zvipenyu zviri mumitumbi yemvura hazvigone kurarama, zvichiparadza chiyero che ecological; kana mvura yetsvina ikapinda muvhu, inosvibisawo mvura yepasi, zvichikanganisa kuchengeteka kwemvura yekunwa yevanhu. Uyezve, zvimwe zvinhu zvine muchetura uye zvine njodzi mumvura yetsvina zvinogona kupfuudzwa mucheni yechikafu uye zvozopedzisira zvapinda mumuviri wemunhu, zvichiisa njodzi kuhutano hwevanhu, zvinoda kurapwa kwehunyanzvi nemidziyo yekuchenesa mvura yakawandisa.
Parizvino, iyo yakakwira yetsvina yemvura yatinogona kufananidza inosanganisira: makemikari indasitiri mvura yetsvina, mishonga inorasa mvura, kudhinda nekudhaya tsvina yemvura, electroplating tsvina yemvura uye zvichingodaro. Mvura inoraswa iyi inogona kunge iine huwandu hukuru hwezvinhu zvakasimukira, inorganic matter, heavy metals, chepfu uye zvine njodzi.
Matambudziko mukurapa yakakwira yetsvina mvura yakakura, kunyanya kusanganisira: kutanga,. High concentration: kuwandisa kwezvinosvibisa mumvura yetsvina kunoda nzira dzine simba dzekurapa dzekubvisa zvinobudirira. Chechipiri, kuumbwa kwakaoma: yakawandisa mvura yakasvibiswa kazhinji ine zvakasiyana-siyana zvinosvibisa, uye kuumbwa kwayo kwakaoma, zvichiita kuti zvive zvakaoma kurapa. Chechitatu, kushata kwe biodegradability: imwe yemvura yakasviba yakanamirwa haina kuodza, uye inoda kufanogadziriswa nedzimwe nzira dzekurapa. Chechina, huturu hwepamusoro: imwe yakakwira-yakadzika tsvina inogona kunge iine zvinhu zvine muchetura, zvichiunza njodzi yekuchengetedza kune michina yekurapa nevashandisi. Chechishanu, kuomerwa kwekutsvaga: yakakwira yakadzika tsvina mukurapwa, kuti uwane kuoma kwekutsvaga nekushandisa zvakare.
Parizvino, yakakwira yemvura yetsvina yekuchenesa michina inoda kubata nerudzi urwu rwemvura yetsvina, kunyanya kushandisa nzira yekurapa yemuviri, makemikari nzira yekurapa, biological kurapwa nzira, membrane kupatsanurwa nzira, yepamusoro oxidation nzira, nezvimwewo, kurapwa chaiko, kazhinji zvinoenderana ne maitiro emvura yakasviba uye zvinodiwa pakurapa, sarudza nzira yakakodzera yekurapa kana musanganiswa wenzira dzakasiyana.
Liding yekuchengetedzwa kwezvakatipoteredza inyanzvi inobata mukutsvaira kwetsvina kweanopfuura makore gumi nguva, kugadzirwa kwayo uye kutsvagisa uye kusimudzira yakakwira-yakadzika yakasviba michina yeBlue Whale yakatevedzana, zuva nezuva inogona kugadzirisa anopfuura zana matani emvura yakasviba-yakanyanya, yakasimba uye yakasimba, inodhura-inoshanda, tsvina inosangana nezviyero.
