N’chifukwa chiyani dziwe lanu losambira limasintha mtundu?

Chifukwa chachikulu cha kusinthika kwa madzi a dziwe losambira ndi mtundu wa madzi operekedwa ndi kuwonetsera ndi kuchulukitsa kwa zinthu za chromogenic pamtunda waukulu wa pansi pa dziwe.Izi zikutanthauza kuti kuya kwa mtundu wa madzi a dziwe kumayenderana ndi kukula ndi kuya kwa dera la pansi pa dziwe.Pamene kuchuluka kwa zinthu za chromogenic m'madzi kumakhala kofanana, mtundu wa dziwe lalikulu kapena lakuya limakhala lakuda komanso lakuda kuposa la dziwe laling'ono kapena losaya, Monga ngati kugwiritsa ntchito beaker kutulutsa madzi obiriwira a dziwe kapena kupopera. dziwe laling'ono, mulibe mtundu mkati mwake;Zifukwa zazikulu zakusinthika kwamadzi am'dziwe zimaphatikizapo kusefukira kwa algae wobiriwira, kuchuluka kwa mchere wamitundu m'madzi, fyuluta ejecta, mtundu woyamba wa mankhwala ophera tizilombo komanso kusowa kwa chlorine, ndi zina zambiri.

1. Chimake cha Algae:

Pamene madzi mu dziwe ali ndi katundu wolemetsa, mankhwala ophera tizilombo toyambitsa matenda monga chlorine kapena ozoni ali otanganidwa kuwononga ndi kuwononga zinthu zamoyo zomwe osambira amakhetsedwa, ndipo alibe nthawi yoganizira za zomera zobiriwira zomwe zimabweretsedwa ndi fumbi.Pamene kukula kwawo (kuwala, kutentha, carbon dioxide, feteleza) kuli koyenera, nthawi yomweyo amagawanika ndikukula, zomwe zimapangitsa kuti madzi adziwe kuti asinthe.Mwachitsanzo, mvula yamkuntho yotentha yachilimwe, kumene madzi amvula amasintha nayitrogeni kuchokera mumpweya woyambitsidwa ndi mphezi kukhala nitrate, feteleza wamkulu wa algae wobiriwira, ndikumutsuka mu dziwe losambira, ndi chitsanzo chodziwika bwino cha kusefukira kwa ndere zobiriwira.

2. Zomwe zili m'madzi zopanda ferrous ndizokwera kwambiri:

Powonjezera oxidizing mankhwala ophera tizilombo toyambitsa matenda monga chlorine kapena ozoni ku kutentha, magwero a madzi amchere, maiwe osambira opanda ndalama zotenthetsera, kapena maiwe osambira omwe angosefukira kumene, chifukwa cha kuchuluka kwa madzi omwe amabayidwa, kuchuluka kwa zitsulo zolemera monga chitsulo, mkuwa, kapena manganese. m'madzi ndi okwera.Powonjezera oxidizing mankhwala ophera tizilombo monga chlorine kapena ozone, apanga dziko lokhala ndi okosijeni, zomwe zimapangitsa kuti madzi a dziwe azikhala ndi mitundu yachilendo.Kuonjezera apo, ngati copper sulfate, aluminium sulfate, kapena polyaluminium chloride agwiritsidwa ntchito, madzi a padziwe amatha kupanga mitundu yowoneka bwino ya buluu monga copper hydroxide, copper carbonate, kapena mitundu yoyera yamkaka monga aluminium hydroxide chifukwa chosakwanira kuwongolera alkalinity yonse.

3. Sefa yotulutsa:

Tizidutswa ta m'madzi a dziwe timawunjika ndikukhazikika ndi fyuluta, zomwe zimapangitsa kuti fyulutayo isunthike ndikumasuka pazifukwa zina, zomwe zimapangitsa kuti zinyalala zomwe zidatengedwa ndi zosefera zilowe muzosefera (Kudutsa) ndikupanga mdima wobiriwira. kapena madzi akuda kukokera ndi kutuluka.

4. Mtundu woyamba wa mankhwala ophera tizilombo:

Chlorine mu mankhwala ophera tizilombo toyambitsa matenda ndi mankhwala ophera tizilombo toyambitsa matenda ndi obiriwira achikasu, okhala ndi mamolekyu otsika omwe amapangitsa kuti zikhale zovuta kuyika utoto m'madzi a dziwe, pomwe bromine ndi wolemera kwambiri wamtundu wofiirira wofiirira womwe umawoneka wobiriwira wakuda ukachulukitsidwa ndi madzi a dziwe.Kuphatikiza apo, chlorine dioxide, chifukwa champhamvu yake yachikasu ya fulorosenti, imakonda kukhala ndi mtundu wamadzi wamba kapena wachikasu wobiriwira chifukwa cha dosing.

5. Kuperewera kwa klorini:

Madzi osambira akalemedwa kwambiri, mtengo wa CT wa chlorine chemistry sungathe kuwonetsa kufunikira kwa klorini m'madzi a dziwe mu nthawi yeniyeni.Pamene mphamvu yochepetsera makutidwe ndi okosijeni (ORP) ya madzi a dziwe ikatsika kwambiri pansi pa 600mv, zinthu zamoyo zomwe zili m'madzi a dziwe zimaoneka zoyera komanso zaphokoso chifukwa cha emulsification.
