Maindasitiri emvura ndiyo marara emvura, seage uye kutambisa mvura yakagadzirwa muindasitiri yekugadzira maindasitiri, kazhinji iine zvigadzirwa zvekugadzira maindasitiri, ne-zvigadzirwa uye zvakasvibisa zvakagadzirwa mukugadzira maitiro. Kurapa kwemaindasitiri kunoreva kurapwa kwekurapa nemvura inoshandiswa nemvura inoshandiswa mukugadzirwa kwemaindasitiri yekugadzira kana kugadzirwa zvinobudirira mumunda weindasitiri uye kuderedza kusvibiswa kwezvakatipoteredza. Seimwe yeanonyanya kukosha mukubatanidza kutonga, kurapwa kwemaindasitiri kune hunhu hwekukuvadza, kurwiswa uye kushandisirwa zvakanyanya mumishonga, kudhinda uye kucherwa, makemikari, simbi uye mamwe minda yeindasitiri. Kurapwa kwemaindasitiri emasango kunotora matanho akasiyana ekurapa zvichienderana nehunhu hweanosvibisa mumarara. Zvinoenderana nekuita kwayo kwekurapa, zvinogona kuve
Yakakamurwa kuita nzira yekurapa yemuviri, nzira yekurapa yekurapa, physicochemical yekurapa nzira uye nzira yekurapa yekurapa. Pakati pavo, sludge yakanatswa muBiological kurapwa nzira iyo nzira ine yakakwirira kemikari yekushandura kushanda uye ine yakanaka kurapwa kwekurapa kwesangano mu organic maindasitari Parizvino parizvino iyo inonyanya kushandiswa maindasitiri marara ekurapa ekurapa maitiro.
Nhungamiro yezvirongwa kuti utungamirire kukudziridzwa kwekuchengetedza simba uye kwezvakatipoteredza muindishokemasitire yekuputika kwekurapa kwesangoita seyakakosha maratidziro mukuratidzira kwekutonga, kurapwa kwemaindasitiridzo kwakaita basa rakakosha mukugadzirwa kwemaindasitiri. Muna Gumiguru 2010, Dare reHurumende reChina rakakurudzirwa mu "sarudzo pakusimudzira maindasitiri ekusimbisa Kubudirira kunofambisa kuvandudzwa kwehuwandu hwakazara hwekushanda kwesimba. Muna Kubvumbi 2015, Dare reHurumende reChina rakapa chirongwa chechiitiko chekudzivirira uye kudzora kwekusvibiswa kwemvura ("mvura gumi"), icho chiratidzo chekutanga chekutarisirwa kweChina kwemvura yekumaindasitiri. Zvirongwa zvechirongwa zvepamusoro zvezvirongwa gumi zvinokosha sekudhinda zvisiri zvechisimba Uyezve, "Mitemo gumi yemvura" yakaisawo matanho emasimba makumi maviri nematanhatu ekudzora kusvibiswa munzvimbo dzemaindasitiri. Zvinogona kuoneka kuti uchiri kutarisana nekudzora huwandu hwakazara hwekusvibisa discharge, China inobhadhara zvakanyanya kune kuvandudzwa kwemamiriro ekunze emvura uye kudzivirira uye kudzora kwenzvimbo yezvakatipoteredza. Muna Gumiguru 2017, mumushumo weCongress yeCommunress yeCommunist yeCommunist yeChina, inosimbisa mutoro wezvekuratidzira, uye nekuvandudza ruzivo rwezvemamiriro ekunze, kurangwa kwakasimba uye mamwe masisitimu. icharova basa rakakura rinotungamira. Kune rimwe divi, mumutemo wekudzivirira wezvemamiriro ekunze, hurumende yeChinese yakaunzawo mitemo yakakodzera. MunaDecember 2017, Dare reNyika reChina rakatsemura mitemo yekuita mutero wekudzivirira weChina. % LVY Yenharaunda Dziviriro Mutero; Kana iko kusungwa kwesvibisa kuri kuderera kupfuura 50.0% yeiyo pollutant discharge standard standard nehurumende uye yemuno mutero, mutero wekudzivirira wenzvimbo uchave wakadhindwa muyero we50.0%. Mushure mekuita kwegwaro iri, kuunganidzwa kwemhosva yekunyepedzera kwakabviswa, iko kukosha kukuru kwekuchengetedza nekuvandudza nharaunda, nekudzora kusvibiswa kwemisangano, uye kusimudzira kuvakwa kwebudiriro yezviratidzo.
Kwayedza: Inoratidza neSullivan Institute Water Market Technology uye nzira nzira icharatidza maitiro akasarudzika ekuvandudza. Pasi pemashure memarongerwo enyika Nekuda kwekunetseka kwemvura yeindasitiri, iyo
Zvakaoma kune imwe tekinoroji yekuzadzisa iyo yaunoda mhedzisiro. Naizvozvo, mabhizinesi ekusungwa ekurwara anodikanwa anodiwa pakusanganiswa kwekutsamwa muyambiro, nzira dzinoenderana, uye synergistic nzira kuburikidza nekushandiswa kwezvinhu zvakanaka zvemvura, sekusanganiswa kwemakemikiki. Nzira dzekurapa, nzira dzeMakemikari dzakabatanidzwa dzakabatanidzwa, nezvimwe, kuitira kuti uwane zvinangwa zvekunyanyisa kugona, kudyiwa kwakaderera uye kudzivirirwa kwezvakatipoteredza. Kune rimwe divi, mukutenderera kwemvura inoyevedza yemvura ine huwandu hwekushandiswa kwemvura, asi nekuda kweiyo phosphorus yakanangana nemvura iyi uye inokonzeresa mumvura, ichikonzera kusvibiswa kwemvura uye kusvibiswa kwemvura. Naizvozvo, nekuvandudzwa kweChinese muindasitiri masango ekurapa tekinoroji, iyo phosphorous kana isiri-nitrogen yemhando yemvura yekuita makemikari ichave nzira yekutsvaga yekutsvaga kwemaindasitiri ekurapa kwemasango.
Hurumende yeChinese yakaburitsa nhevedzano yekudzivirirwa yezvemamiriro ekunze Nekufambira mberi zvishoma nezvishoma kwezvirongwa zvine chekuita neindasitire mune dzakasiyana-siyana maindasitiri emapaki, uye maindasitiri emasitiri eChina.
