Ichokwadi kuti kuwedzeraChlorinezvinokanganisa pH yedziva rako. Asi kana iyo pH level inowedzera kana kuderera zvinoenderana nekuti iyoChlorine Disinfectantyakawedzerwa padziva ine alkaline kana acidic. Kuti uwane rumwe ruzivo nezve chlorine disinfectants uye hukama hwavo nepH, verenga.
Kukosha kweChlorine Disinfection
Chlorine ndiyo kemikari inonyanya kushandiswa pakushambira mudziva rekushambira. Izvo hazvienzaniswi mukubudirira kwayo pakuuraya mabhakitiriya anokuvadza, mavhairasi, uye algae, zvichiita kuti ive chinhu chakakosha mukuchengetedza hutsanana hwemadziva. Chlorine inouya nenzira dzakasiyana, senge sodium hypochlorite (mvura), calcium hypochlorite (yakasimba), uye dichlor (upfu). Pasinei nechimiro chinoshandiswa, kana chlorine yawedzerwa mumvura yedziva, inopindirana kuumba hypochlorous acid (HOCl), mushonga unouraya utachiona unodzora utachiona.
Kuwedzera chlorine yakaderera pH?
1. Sodium hypochlorite:Ichi chimiro cheklorini, kazhinji chinouya chiri muchimiro chemvura, chinowanzozivikanwa se bleach kana liquid chlorine. Ne pH ye13, ine alkaline. Zvinoda kuwedzerwa kweasidhi kuchengetedza dziva remvura risina kwayakarerekera.
2. Calcium hypochlorite:Kazhinji inouya mune granules kana mahwendefa. Inowanzonzi "calcium hypochlorite", ine zvakare yakakwira pH. Kuwedzera kwayo kunogona kutanga kusimudza pH yedziva, kunyangwe mhedzisiro yacho isiri inoshamisa se sodium hypochlorite.
3. TrichloruyeDichlor: Aya ane acidic (TCCA ine pH ye2.7-3.3, SDIC ine pH ye5.5-7.0) uye inowanzoshandiswa muhwendefa kana granule fomu. Kuwedzera trichlor kana dichlor padziva kunodzikisira pH, saka iyi mhando yechlorine disinfectant inogona kudzikisa iyo pH yese. Mhedzisiro iyi inofanirwa kutariswa kudzivirira mvura yedhamu kuti isanyanya kuwandisa.
Basa repH mukudziva disinfection
pH chinhu chakakosha mukubudirira kweklorini semushonga wekuuraya utachiona. Iyo yakakodzera pH yemhando yemadziva ekushambira inowanzova pakati pe7.2 - 7.8. Rudzi urwu runovimbisa kuti chlorine inoshanda panguva yekugadzika kune vanoshambira. Pa pH mazinga ari pasi pe7.2, chlorine inova yakawandisa uye inogona kutsamwisa maziso evashahwi neganda. Sezvineiwo, pamazinga epH ari pamusoro pe7.8, chlorine inorasikirwa nekushanda kwayo, zvichiita kuti dziva rive nyore kukura kwebhakitiriya uye algae.
Kuwedzera chlorine kunokanganisa pH, uye kuchengeta pH mukati meiyo yakanakira chiyero kunoda kunyatsotarisisa. Kunyangwe chlorine inosimudza kana kuderedza pH, kuwedzera pH inogadzirisa kwakakosha kuchengetedza chiyero.
Izvo pH zvinogadzirisa zvinoita
pH inogadzirisa, kana pH kuenzanisa makemikari, anoshandiswa kugadzirisa pH yemvura kusvika padanho rinodiwa. Kune maviri makuru marudzi epH anogadzirisa anoshandiswa mumadziva ekushambira:
1. pH Inowedzera (Bases): Sodium carbonate (soda ash) inowanzoshandiswa pH inowedzera. Kana pH iri pasi peyero yakakurudzirwa, inowedzerwa kusimudza pH uye kudzoreredza chiyero.
2. pH Reducers (Acids): Sodium bisulfate inowanzoshandiswa pH inoderedza. Kana pH yakanyanyisa, makemikari aya anowedzerwa kuti adzikise kusvika kune yakakwana.
Mumadziva anoshandisa acidic chlorine, senge trichlor kana dichlor, pH inowedzera inowanzodiwa kurwisa kudzikisira kwepH. Mumadziva anoshandisa sodium kana calcium hypochlorite, kana pH yakanyanya kukwira mushure mekunatswa, inoderedza pH inogona kudiwa kudzikisa pH. Ehe, kuverenga kwekupedzisira kwekushandisa kana kusashandisa, uye kuti ingani yekushandisa, inofanira kubva pane chaiyo data iripo.
Kuwedzera chlorine padziva kunokanganisa pH yayo, zvichienderana nerudzi rwechlorine inoshandiswa.Chlorine Disinfectantsizvo zvine acidic zvakanyanya, senge trichlor, zvinowanzo kudzika pH, nepo mamwe alkaline chlorine disinfectants, senge sodium hypochlorite, inosimudza pH. Kugadziriswa kwedziva kwakaringana hakudi chete kuwedzerwa nguva dzose kweklorini yekuuraya utachiona, asiwo kunyatsotarisisa uye kugadzirisa pH uchishandisa pH inogadzirisa. Iyo yakaringana yepH inova nechokwadi chekuti simba rekuuraya utachiona re chlorine rinowedzerwa pasina kukanganisa kushambira. Nekuenzanisa izvo zviviri, varidzi vemadziva vanogona kuchengetedza yakachena, yakachengeteka, uye yakagadzika nzvimbo yekushambira.
