Residual chlorine inoreva kuti mushure mekunge mishonga ine chlorine ine utachiona yaiswa mumvura, pamwe nekudya chikamu chehuwandu hweklorini kuburikidza nekubatana nebhakitiriya, mavhairasi, organic matter, uye inorganic matter mumvura, chikamu chasara chehuwandu hwemvura. chlorine inonzi residual chlorine. Inogona kukamurwa kuita yemahara yakasara chlorine uye yakasanganiswa yakasara chlorine. Huwandu hweaya maviri asara ma chlorine anodaidzwa kuti yakazara residual chlorine, inogona kushandiswa kuratidza iyo yese disinfection mhedzisiro yemitumbi yemvura. Masangano akakodzera munzvimbo dzakasiyana anogona kusarudza kuona yasara chlorine kana yakazara yasara chlorine zvinoenderana neakakodzera zviyero uye chaiwo mamiriro emitumbi yemvura. Pakati pavo, iyo yakasununguka yakasara chlorine inowanzo mahara chlorine muchimiro cheCl2, HOCl, OCl-, nezvimwewo; iyo yakasanganiswa yakasara chlorine ndiyo chloramines NH2Cl, NHCl2, NCl3, nezvimwewo inoumbwa mushure mekuita kwemahara chlorine uye ammonium zvinhu. Iyo yakasara chlorine yatinowanzo taura kazhinji inoreva yakasununguka yakasara chlorine.
Residual chlorine/total residual chlorine ine zvakasiyana zvinodiwa pamvura yekunwa yemumba, mvura yepamusoro, uye tsvina yekurapa. Pakati pavo, iyo "Drinking Water Sanitation Standard" (GB 5749-2006) inoda kuti yakasara chlorine kukosha kwefekitari yemvura yemvura yekugovera mvura inodzorwa pa 0.3-4.0mg/L, uye yakasara chlorine yemukati pakupera kwe iyo pombi network haifanire kuve isingasviki 0.05mg/L. Kuwanda kweklorini yakasara mumvura yekunwa yepakati pemvura yepamusoro inofanira kunge iri pasi pe0.03mg/L. Kana huwandu hweklorini yasara yakakura kudarika 0.5mg/L, inofanira kuziviswa kubazi rekuchengetedza nharaunda. Zvinoenderana nemhando dzakasiyana dzekuburitsa uye minda yekurasira yetsvina yekurapa, izvo zvinodikanwa zveiyo yakazara yasara chlorine pakubuda kwe disinfection yekusangana dziva zvakasiyana.
Nekuti yasara chlorine uye yakazara yasara chlorine haina kugadzikana mumiviri yemvura, mafomu avo aripo anokanganiswa nyore nezvinhu zvakaita setembiricha uye chiedza. Nokudaro, kuonekwa kweklorini yakasara uye yakazara chlorine yakasara inowanzokurudzirwa kuti ikurumidze kuonekwa panzvimbo yekuenzanisa kuti ive nechokwadi chekuonekwa. Nzira dzekuona dzakasara chlorine uye yakazara yakasara chlorine inosanganisira "HJ 586-2010 Kutemerwa kwemahara chlorine uye yakazara chlorine mumhando yemvura N,N-diethyl-1,4-phenylenediamine spectrophotometric method", electrochemical method, reagent method, nezvimwewo. Lianhua Technology LH-CLO2M Inotakurika Chlorine Meter inogadzirwa zvichibva paDPD spectrophotometry, uye kukosha kunogona kuwanikwa muminiti imwe. Inoshandiswa zvakanyanya mukutarisa-chaiyo-nguva yekutarisa yakasara chlorine uye yakazara yasara chlorine nekuda kwekuona kwayo kurongeka uye nyore kushanda pabasa.
