Mvura yakasviba yemaindasitiri imvura yakasviba, tsvina yetsvina uye marara anogadzirwa mukugadzirwa kwemaindasitiri, anowanzo kuve nezvinhu zvekugadzira maindasitiri, zvigadzirwa zvinobva muindasitiri uye tsvina inobuda mukugadzirwa. Kurapa mvura yakasviba yemaindasitiri kunoreva nzira yekurapa mvura inoshandiswa mukugadzirwa kwemaindasitiri pakugadzirwa kana kuburitswa kubva mufekitori, iyo inogona kurapa mvura yakasviba inogadzirwa mumunda wemaindasitiri uye kuderedza kusvibiswa kwezvakatipoteredza. Seimwe yenzira dzakakosha mukutonga kwezvakatipoteredza, kurapwa kwemvura yakasviba yemaindasitiri kune hunhu hwekusakuvadza, kuderedzwa uye kugarisana nevamwe, uye kunoshandiswa zvakanyanya mumishonga, kudhinda nekudhaya, makemikari, simbi nedzimwe nzvimbo dzeindasitiri. Kurapa mvura yakasviba yemaindasitiri kunotora matanho akasiyana ekurapa zvichienderana nehunhu hwetsvina mumvura yakasviba. Zvichienderana nemaitiro ayo ekurapa, inogona kutorwa se
Yakakamurwa kuita nzira yekurapa nemuviri, nzira yekurapa nemakemikari, nzira yekurapa nemakemikari uye nzira yekurapa nemuviri. Pakati padzo, tsvina inoshandiswa mukurapa nemakemikari. Nzira iyi inoshanda zvakanyanya pakushandura makemikari uye ine mhedzisiro yakanaka pakurapa tsvina mumvura yakasviba yemumaindasitiri. Parizvino ndiyo nzira yekurapa mvura yakasviba inoshandiswa zvakanyanya mumaindasitiri.
Kuunzwa kwemitemo yekutungamira kuvandudzwa kwekuchengetedza simba nekuchengetedzwa kwezvakatipoteredza muindasitiri yekurapa mvura yakasviba yeindasitiri. Seimwe yenzvimbo dzakakosha mukutonga kwezvakatipoteredza, kurapwa kwemvura yakasviba yeindasitiri kwakaita basa rakakosha mukugadzirwa kwemaindasitiri. Muna Gumiguru 2010, Dare reHurumende reChina rakapa mu "Sarudzo yekukurumidzira Kurima neKuvandudza Maindasitiri Ari Kukura Emazano" kuti kuchengetedza simba nekuchengetedzwa kwezvakatipoteredza zvinofanira kuonekwa seimwe yemaindasitiri manomwe ari kubuda, achitarisa pakusimudzira michina yehunyanzvi inochengetedza simba nezvigadzirwa, uye kuita matekinoroji akakosha munzvimbo dzakakosha. Kubudirira kuchatungamira kuvandudzwa kwehuwandu hwese hwekushandisa simba. Muna Kubvumbi 2015, Dare reHurumende reChina rakaburitsa Chirongwa Chekuita Chekudzivirira neKudzora Kusvibiswa kweMvura ("Water Ten"), chinova chiratidzo chekutanga chekutarisira kweChina kurapwa kwemvura yeindasitiri. Zvirongwa zvakakosha zvekurapa zvemaindasitiri gumi akakosha akadai sesimbi dzisina feri, kudhinda nekudhaya, kubika, uye kugadzira maAPI zvinoitwa, uye shanduko yakachena inoiswa kuti kuzadzisa chinangwa chekugadzirisa kusvibiswa kwemvura. Pamusoro pezvo, "Gumi reMitemo yeMvura" rakaisawo matanho akasimba mazana maviri nemakumi matatu nemasere ekudzora kusvibiswa munzvimbo dzemaindasitiri. Zvinogona kuonekwa kuti nepo ichitarisa pakuderedza huwandu hwese hwekusvibiswa, China inonyanya kutarisisa kuvandudzwa kwemhando yemvura uye kudzivirira nekudzora njodzi dzezvakatipoteredza. Muna Gumiguru 2017, mumushumo we19th National Congress yeCommunist Party yeChina, zvaidikanwa kuvandudza mwero wekusvibiswa, kusimbisa mutoro wevanosvibisa, uye kuvandudza kuongororwa kwechikwereti chezvakatipoteredza, kuburitswa kwemashoko anosungirwa, chirango chakakomba nedzimwe nzira. zvichatamba basa guru rekutungamira. Kune rumwe rutivi, mumutemo wemitero yekuchengetedzwa kwezvakatipoteredza, hurumende yeChina yakaunzawo mitemo yakakodzera. Muna Zvita 2017, Dare reNyika reChina rakaburitsa Mitemo yeKushandiswa kweMutemo weKudzivirirwa kwezvakatipoteredza wePeople's Republic of China, ichida kuti vateresi vaburitse mvura inosvibisa ine kukosha kwayo kwakaderera pane 30.0% yemuyero wekusvibiswa kwezvinosvibisa wakatarwa nehurumende dzematunhu nedzemunharaunda, nekudzikiswa kwe75.0%. % inobhadharisa mutero wekuchengetedzwa kwezvakatipoteredza; Kana huwandu hwezvinosvibisa huri pasi pe50.0% yemutemo wekuburitsa zvinosvibisa wakatarwa nehurumende dzematunhu nedzemunharaunda, mutero wekuchengetedza nharaunda uchaderedzwa ne50.0%. Mushure mekuitwa kwemutemo uyu, kuunganidzwa kwemari yetsvina kwakabviswa, izvo zvakakosha zvikuru pakudzivirira nekuvandudza nharaunda, kuderedza kuburitsa zvinosvibisa, uye kukurudzira kuvaka kwehupenyu hwezvakatipoteredza.
Chitubu: Zvakaratidzwa neSullivan Institute tekinoroji yekurapa mvura uye nzira yekushanda zvicharatidza mafambiro akasiyana-siyana ebudiriro. Zvichitevera mitemo yenyika yakanaka, kugona kweChina kugadzira tekinoroji yekurapa mvura yakasviba mumaindasitiri kwakagadziridzwa zvikuru, izvo zvakasimudzira kuvandudzwa kwedanho rekurapa mvura yakasviba mumaindasitiri muChina. Nekuda kwekuoma kwezvinosvibisa mvura mumaindasitiri, zvakabatsira
Zvinonetsa kuti tekinoroji imwe chete iwane mhedzisiro inodiwa. Nokudaro, makambani ekurapa mvura yakasviba mumaindasitiri anofanirwa kuita tsvakiridzo yakabatana munzira dzakasiyana-siyana, dzinoenderana, uye dzinoshanda pamwe chete kuburikidza nekushandisa matekinoroji akakwana ekurapa mvura, akadai sekubatanidza makemikari nemuviri. Nzira dzekurapa, nzira dzekurapa dzakabatana nemakemikari nehupenyu, nezvimwewo, kuitira kuti zvizadzise zvinangwa zvekushanda zvakanyanya, kushandiswa kushoma uye kuchengetedzwa kwezvakatipoteredza. Kune rumwe rutivi, muhurongwa hwemvura inotonhorera inotenderera ine huwandu hwakawanda hwekushandiswa kwemvura, fomura yemakemikari yakavakirwa pachiyero ndiyo inonyanya kushandiswa, asi nekuda kwekuti phosphorus-based corrosion uye scale inhibitor mufomura iyi inogona kushanda sechikafu chebhakitiriya nealgae mumvura, zvichikonzera kusvibiswa kwemvura. Eutrophication uye kusvibiswa kwemvura. Naizvozvo, nekuvandudzwa kwetekinoroji yekurapa mvura yakasviba yeindasitiri yeChina, kuvandudzwa kwemakemikari ekurapa mvura ane phosphorus shoma kana kuti non-phosphorus, non-nitrogen, biodegradable, multi-functional uye nharaunda achava nzira huru yekutsvagisa yekurapa mvura yakasviba mumaindasitiri.
Hurumende yeChina yaburitsa mitemo yakawanda yekuchengetedza nharaunda, ichida kuti makambani kana masangano ane chekuita nebasa remaindasitiri adzore zvakasimba mvura yakasviba yemumaindasitiri, izvo zvakave nebasa rinodzvinyirira mukuburitswa kwemvura yakasviba nemakambani uye zvakakurudzira kukura kwekudiwa kweindasitiri yekurapa mvura yakasviba yemumaindasitiri. Nekufambira mberi zvishoma nezvishoma kwemapurojekiti ekurapa mvura yakasviba yemumaindasitiri munzvimbo dzakasiyana-siyana dzemaindasitiri, nzvimbo dzekuvandudza maindasitiri epamusoro, uye nzvimbo dzemaindasitiri ezvakatipoteredza muChina, kukura kwemusika wekurapa mvura yakasviba yemumaindasitiri muChina kucharamba kuchikwira.
