Zvinoenderana nedata, bhatiri rine bhatani rimwe chete rinogona kusvibisa marita 600000 emvura, ayo anogona kushandiswa nemunhu kwehupenyu hwake hwese. Kana chikamu chebhatiri Nhamba 1 chikakandwa mumunda unorimwa zvirimwa, 1 square mita yevhu rakakomberedza bhatiri iri rinosara risina chinhu. Sei zvakazove zvakadai? Nekuti mabhatiri aya ane huwandu hwakawanda hwesimbi dzinorema. Semuenzaniso: zinc, lead, cadmium, mercury, nezvimwewo. Simbi idzi dzinorema dzinopinda mumvura uye dzinotorwa nehove nezvirimwa. Kana vanhu vakadya hove idzi dzakasvibiswa, shrimp nezvirimwa, vachatambura nehuturu hweMercury uye zvirwere zvepakati petsinga, nehuwandu hwerufu hunosvika 40%. Cadmium inozivikanwa seClass 1A Carcinogen.

Mabhatiri emarara ane simbi dzinorema dzakadai se mercury, cadmium, manganese, uye lead. Kana pamusoro pemabhatiri pakaita ngura nekuda kwezuva nemvura, zvinhu zvesimbi zvinorema zviri mukati zvinopinda muvhu nemumvura yepasi. Kana vanhu vakadya zvirimwa zvinogadzirwa panyika yakasviba kana kunwa mvura yakasviba, simbi idzi dzine chepfu dzichapinda mumuviri wemunhu dzodonha zvishoma nezvishoma, zvichikonzera njodzi huru kuhutano hwevanhu.

Kana mercury iri mumabhatiri etsvina yazara, kana ikapinda mumasero europi hwevanhu, sisitimu yetsinga inokuvadzwa zvakanyanya. Cadmium inogona kukonzera kukuvara kwechiropa neitsvo, uye muzviitiko zvakakomba, kushanduka kwemapfupa. Mamwe mabhatiri etsvina anewo acid neheavy metal lead, izvo zvinogona kukonzera kusvibiswa kwevhu nemvura kana zvikadonhedzwa muzvisikwa, zvichizopedzisira zvakonzera njodzi kuvanhu.
Nzira yekurapa mabhatiri

1. Kupatsanura
Pwanya bhatiri rakadzokororwa, bvisa zinc shell nesimbi yepasi pebhatiri, bvisa chivharo chemhangura netsvimbo yegirafiti, uye chinhu chitema chasara chichava musanganiswa weManganese dioxide neammonium chloride zvinoshandiswa sepakati pebhatiri. Unganidza zvinhu zviri pamusoro apa wozvigadzira kuti uwane zvimwe zvinhu zvinobatsira. Tsvimbo yegirafiti inogezwa, yoomeswa, uye yozoshandiswa seelectrode.

2. Zinc granulation
Geza ganda rezinc rakabviswa woriisa muhari yesimbi. Ripise kuti rinyunguduke worichengeta richidziya kwemaawa maviri. Bvisa scum yepamusoro, uidururire kuti itonhore, woidonhedza pandiro yesimbi. Mushure mekuoma, zvidimbu zvezinc zvinowanikwa.

3. Kudzokorodza mapepa emhangura
Mushure mekufukidza chivharo chemhangura, chisuke nemvura inopisa, wobva wawedzera huwandu hwakati hwe10% sulfuric acid kuti ufashaire kwemaminitsi makumi matatu kuti ubvise pamusoro pe oxide layer. Bvisa, suka, woomesa kuti uwane copper strip.

4. Kudzoreredzwa kweammonium chloride
Isa chinhu chitema musirindiri, wedzera mvura inodziya ye60oC wobva wakurunga kweawa imwe chete kuti unyungudise ammonium chloride yese mumvura. Rega imire, sefa, wosuka zvasara zvefirita kaviri, wounganidza doro remumai; Mushure mekunge doro remumai rabviswa muVacuum kusvika firimu jena rekristaro raonekwa pamusoro, rinotonhodzwa uye rosefa kuti riwane ammonium chloride crystals, uye doro remumai rinodzokororwa.

5. Kudzorerwa kweManganese dioxide
Gezai zvakasara zvefirita zvakaseferwa nemvura katatu, svinai, isai keke refirita muhari moripisa neutsi kuti mubvise kabhoni shoma nezvimwe zvinhu zvipenyu, mozoisa mumvura mokurunga-kurunga kwemaminitsi makumi matatu, svinai, omesai keke refirita pa100-110oC kuti muwane Manganese dioxide nhema.

6. Kuomesa, kuviga zvakadzika, uye kuchengetwa mumigodhi yakasiyiwa
Semuenzaniso, imwe fekitori muFrance inoburitsa nickel ne cadmium kubva mairi, izvo zvinozoshandiswa kugadzira simbi, nepo cadmium ichishandiswazve mukugadzira mabhatiri. Mamwe mabhatiri emarara anowanzo endeswa kunzvimbo dzemarara dzine chepfu uye dzine njodzi, asi tsika iyi haingodhuri chete, asiwo inokonzera marara, nekuti kuchine zvinhu zvakawanda zvinobatsira zvinogona kushandiswa sezvinhu zvekugadzira.
