Unoita sei kuti dziva rive revana vanotanga?

Nyaya mbiri huru mukugadzirisa dziva remvura ndedzinotimushonga wekuuraya utachiona mudzivauye kusefa. Tichazvizivisa chimwe nechimwe pazasi.

Nezvekuuraya utachiona:

Kune vanotanga, chlorine ndiyo sarudzo yakanakisa yekuuraya utachiona. Kuuraya utachiona nechlorine kuri nyore. Varidzi vedziva vazhinji vakashandisa chlorine kuuraya utachiona mudziva ravo uye vane ruzivo rwakawanda rwakawanda. Kana uine dambudziko, zviri nyore kuwana mumwe munhu wekubvunza mibvunzo nezve chlorine.

Zvinhu zvinowanzoshandiswa zve flocculant zvinosanganisirasodium dichloroisocyanurate(SDIC, NaDCC), trichloroisocyanuric acid (TCCA), calcium hypochlorite nemvura inobvisa tsvina. Kune vanotanga, SDIC neTCCA ndiyo sarudzo yakanakisisa: iri nyore kushandisa uye yakachengeteka kuichengeta.

Pfungwa nhatu dzaunofanira kunzwisisa usati washandisa chlorine: Chlorine isina chlorine inosanganisira hypochlorous acid nehypochlorite zvinogona kuuraya mabhakitiriya zvinobudirira. Chlorine yakasanganiswa ichlorine yakasanganiswa nenitrogen uye haigone kuuraya mabhakitiriya. Uyezve, Chlorine yakasanganiswa ine hwema hwakasimba hunogona kutsamwisa nzira dzekufema dzevanoshambira uye kutokonzera asthma. Huwandu hwechlorine isina chlorine nechlorine yakasanganiswa hunonzi total chlorine.

Mugadziri wedziva anofanira kuchengetedza huwandu hwechlorine yakasununguka iri pakati pe1 kusvika 4 mg/L uye chlorine yakabatana iri pedyo ne zero.

Mazinga echlorine anochinja nekukurumidza kana vanhu vatsva vachishambira uye zuva richipenya, saka anofanira kuongororwa nguva nenguva, kwete pasi pekaviri pazuva. DPD inogona kushandiswa kuona chlorine yasara uye chlorine yese zvakasiyana kuburikidza nematanho akasiyana. Ndokumbirawo mutevere mirairo yekushandisa pakuedza kudzivirira zvikanganiso.

Kumadziva ekunze, cyanuric acid yakakosha kudzivirira chlorine kubva kuzuva. Kana ukasarudza calcium hypochlorite nemvura inobvisa bleaching, usakanganwa kuwedzera cyanuric acid yakawanda mudziva rako rekushambira kuti iwedzere huwandu hwayo kusvika pa20 kusvika 100 mg/L.

Nezve kusefa:

Shandisa flocculant ine mafirita kuti mvura igare yakachena. Maflocculant anoshandiswa zvakanyanya anosanganisira aluminum sulfate, polyaluminum chloride, pool gel uye Blue Clear Clarifier. Chimwe nechimwe chine zvakanakira nezvachinokanganisa, ndapota tarisai mirairo yemugadziri wekushandisa.

Midziyo inonyanya kushandiswa yekusefa ndiyo jecha rinosefa. Yeuka kutarisa kuverengwa kwe pressure gauge yayo vhiki nevhiki. Kana kuverenga kwacho kwakanyanya, geza jecha rako rekusefa zvichienderana negwaro remugadziri.

Sefa yekaturiji inonyanya kukodzera madziva madiki ekushambira. Kana ukaona kuti kushanda kwesefa kwaderera, unofanirwa kubvisa katuriji woichenesa. Nzira iri nyore yekuchenesa ndeyekuisuka nemvura pakona ye45-degree, asi kuisuka uku hakuzobvisi algae nemafuta. Kuti ubvise mavara ealgae nemafuta, unofanira kunyikisa katuriji nemuchina wekuchenesa wakasarudzika kana 1:5 dilute hydrochloric acid (kana mugadziri achibvuma) kweawa imwe chete, wozoisuka zvakanaka nemvura inoyerera. Dzivisa kushandisa mvura inoyerera nesimba kuchenesa sefa, zvinokuvadza sefa. Dzivisa kushandisa mvura inochenesa sefa kuchenesa sefa. Kunyangwe mvura inochenesa sefa ichishanda zvakanaka, ichapfupisa hupenyu hwekaturiji.

Jecha riri musefa rejecha rinofanira kutsiviwa makore ese mashanu kusvika manomwe uye katuriji yesefa rekaturiji inofanira kutsiviwa makore ese 1-2.

Kazhinji, kubvisa utachiona uye kusefa zvinobudirira zvakakwana kuchengetedza mvura yedziva ichipenya uye kudzivirira vanoshambira kubva panjodzi yekubatwa nechirwere. Kuti uwane mimwe mibvunzo, unogona kuedza kuwana mhinduro pawebhusaiti yedu. Ivai nezhizha rakanaka!
