Seiboiled themvura yemupombi yekunwa?
Mvura yemupombi inounganidzwa kubva kuchitubu chemvura, mushure mekurapwa kwakaringana uye kuuraya utachiona, uye yozoendeswa kumushandisi kuburikidza nemapombi.Hunhu hwemvura yemupombi hunodzorwa nechiyero chepasi rose chinogona kunzi chinovhara zvinhu zvakasiyana-siyana mumvura yekunwa zvinogona kukanganisa hutano.
Vanhu vazhinji vanobvunza kuti sei vanhu vechiChinese vaigara vachikurudzira kubika mvura vasati vanwa?Muchokwadi, mvura yemupombi inokodzera uye inogona kunwiwa zvakananga.Kufashaidza mvura yemupombi nekunwa itsika, uye nekuda kwengozi dzekusvibisa munharaunda yepombi network uye "secondary water supply" zvivakwa, zvakachengetedzeka kubika mvura yemupombi yekunwa.

Sei mvura yemupombi ichinhuwa kunge bleach?
Mukucheneswa kwemvura yepombi, sodium hypochlorite disinfection process inoshandiswa kuuraya tupukanana mumvura.Iyo National Standard ine mirau yakajeka pane yasara chlorine chiratidzo mumvura yepombi kuti ive nechokwadi chekuchengetedzwa kwemhando yemvura mukuita kwekufambiswa kwemvura yepombi uye kugovera.Nokudaro, vamwe vanhu vane pfungwa yakanyanyisa yekunhuwa vachanzwa kunhuwa kwebleach mumvura yepombi, kureva, kunhuhwirira kweklorini, iyo yakajairika.

Ko chlorine mumvura yemupombi inokonzera gomarara here?
Pane runyerekupe rwepamhepo: Pakubika chikafu, vhura chivharo chepoto wofashaidza mvura usati waisa chikafu, zvikasadaro chlorine inoputira pachikafu ichikonzera gomarara.Uku kusanzwisisa zvachose.
Iko kune chokwadi chakati che "residual chlorine" mumvura yepombi kuve nechokwadi chekudzivirira kwebhakitiriya panguva yekufambisa.Iyo "residual chlorine" mumvura yepombi inonyanya kuvepo muchimiro che hypochlorous acid uye hypochlorite, ine super oxidizing kugona, saka inogona kuuraya mabhakitiriya.Izvo hazvina kugadzikana, uye zvichazowedzerwazve kuchinjwa kuva hydrochloric acid, chloric acid, uye zvishoma zvezvimwe chlorine-containing compounds pasi pemamiriro ezvinhu akadai sechiedza uye kupisa.Kana iri chikafu chinopfungaira, iyo "inosara chlorine" inonyanya kuora kuita chloride, chlorate uye oxygen.Iyo miviri yekutanga haizoputsi, uye iyo yekupedzisira haina kukanganisa hutano.Iyo "carcinogenic theory" haina maturo.

Sei paine chikero (mapurotoni emvura)?
Nezve chiyero, ndiko kuti, mapurotoni emvura, calcium uye magnesium ion anowanzo kuwanikwa mumvura yechisikigo.Mushure mekupisa, ivo vanogadzira chena precipitates.Izvo zvakakosha zvinoumba calcium carbonate uye magnesium carbonate.Izvo zviri mukati zvinogadziriswa nekuoma kwemvura pachayo.Mumamiriro ezvinhu akajairika, kana kuoma kwese mumvura yekunwa kwakakura kupfuura 200mg / L, chiyero chichaonekwa mushure mekubika, asi kana chiri mukati memuganhu unotsanangurwa muhutano, hazvizokanganisa hutano hwevanhu.
Nha.5
Anodaromvura ine oxygen ine hutano here?
Vanhu vazhinji vanotanga kutenga mvura ine okisijeni uye mvura yakafumiswa neokisijeni.Kutaura zvazviri, mvura yemupombi yakajairika ine oxygen.Vanhu havashandise mvura kuzadza oxygen.Kunyangwe kumvura ine oxygen yakawanda, iyo yakanyanya kunyungudika yeokisijeni iri mumvura ndeye 80 ml yeokisijeni parita, nepo vanhuwo zvavo vakuru vane 100 ml yeokisijeni pakufema.Naizvozvo, iyo okisijeni iri mumvura haina kukosha kune vanhu vanofema zuva rose.
