Njira ndi Njira Zopangira Madzi Onyansa Okhala ndi Cyanide kuchokera ku Michira ya Cyanide

M'makampani amigodi, kuchotsa zitsulo zamtengo wapatali nthawi zambiri kumaphatikizapo kugwiritsa ntchito cyanide, zomwe zimapanga madzi ambiri onyansa okhala ndi cyanide kuchokera masamba a cyanide. Madzi otayirawa ndi owopsa kwambiri ndipo amawopseza kwambiri chilengedwe komanso thanzi la anthu ngati sakusamalidwa bwino. Choncho, njira zochiritsira zogwira mtima ndi njira zofunika kwambiri kuti zitsimikizire chitukuko chokhazikika mu gawo la migodi. Nkhaniyi ifotokoza momveka bwino njira zochiritsira ndi njira zamadzi onyansa okhala ndi cyanide kuchokera ku michira ya cyanide.

1. Kufunika Kochitira Madzi Onyansa Omwe Ali ndi Cyanide Kuchokera ku Michira ya Cyanide

Cyanide ndi chinthu chapoizoni kwambiri chomwe chingalepheretse kugwira ntchito kwabwino kwa ma enzymes opuma m'maselo, zomwe zimapangitsa kuti ma cell afe. Ngakhale m'malo otsika kwambiri, cyanide imatha kukhala yovulaza kwambiri zamoyo zam'madzi, ndikusokoneza chilengedwe chamadzi. Ngati madzi onyansa okhala ndi cyanide alowa m'nthaka kapena pansi pa nthaka, amatha kuipitsa magwero amadzi omwe ali ofunikira pakumwa kwa anthu ndi ulimi wothirira, zomwe zingawononge thanzi la anthu ndi ulimi. Kusamalira bwino madzi onyansawa sikofunikira kokha pamalamulo oteteza chilengedwe komanso njira yofunikira kuti mabizinesi amigodi agwire ntchito mokhazikika.

2. Njira Zochizira Wamba

2.1 Chemical Oxidation

• Kutulutsa Chlorine : Iyi ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri potulutsa chlorine. Ma reagents ochokera ku chlorine, monga sodium hypochlorite ndi calcium hypochlorite, amawonjezeredwa m'madzi otayidwa. Chlorine imagwira ntchito ndi ma cyanide ion kuti iwapangitse kukhala cyanate yopanda poizoni poyamba, kenako imapanganso cyanate kukhala Carbon dioxide, nayitrogeni, ndi zinthu zina zopanda vuto. Njira yochitira izi ndi yachangu, koma iyenera kuwongolera mlingo wa oxidant molondola kuti ipewe kugwiritsa ntchito chlorine mopitirira muyeso komanso kupanga zinthu zina zoopsa.

• Kusungunuka kwa Ozone : Ozone ili ndi mphamvu zosungunuka kwambiri. Ikagwiritsidwa ntchito pochiza madzi otayira okhala ndi cyanide, ozone imatha kuchitapo kanthu mwachindunji ndi cyanide kuti iwawononge kukhala zinthu zopanda poizoni. Kusungunuka kwa Ozone kuli ndi ubwino wosakhala ndi kuipitsa kwina komanso kugwiritsa ntchito bwino kwambiri kwa okosijeni. Komabe, ndalama zomwe zimagwiritsidwa ntchito pazida zake ndi zapamwamba kwambiri, ndipo kupanga ndi kugwiritsa ntchito ozone kumafuna mikhalidwe yokhwima yogwirira ntchito.

• Kusungunuka kwa Hydrogen Peroxide : Hydrogen peroxide imathanso kusungunuka kwa cyanide pansi pa mikhalidwe ina. Nthawi zambiri imagwiritsidwa ntchito limodzi ndi zinthu zoyambitsa, monga mchere wachitsulo, kuti iwonjezere kuchuluka kwa kusungunuka kwa okosijeni. Njirayi ndi yabwino kwa chilengedwe, koma nthawi yochitapo kanthu ingakhale yayitali, ndipo kusankha zinthu zoyenera zoyambitsa ndi mikhalidwe yochitapo kanthu ndikofunikira kwambiri kuti chithandizo chigwire bwino ntchito.

2.2 Chithandizo Chachilengedwe

Njira zochiritsira zamoyo zimagwiritsa ntchito tizilombo toyambitsa matenda kuti tiwononge cyanide. Mabakiteriya ena enieni amatha kugwiritsa ntchito cyanide ngati gwero la kaboni ndi gwero la nayitrogeni pakukula ndi metabolism. Pochiza zamoyo, madzi otayira ayenera kukonzedwa kale kuti achotse zinthu zomwe zingawononge tizilombo toyambitsa matenda, ndiyeno madzi onyansawo amalowetsedwa m'njira yochizira, monga sludge system kapena biofilm reactor. Malo oyenera kukula kwa tizilombo tating'onoting'ono, kuphatikizapo kutentha, pH mtengo, mpweya wosungunuka, ndi zina zotero, ziyenera kusamalidwa kuti zitsimikizire kuti ntchito yawo ndi kuwonongeka kwa cyanide. Kuchiza kwachilengedwe kumakhala ndi zabwino zake zotsika mtengo komanso kuipitsa kwachiwiri, koma kumakhudzidwa kwambiri ndi mtundu wamadzi otayidwa ndipo kumafuna nthawi yayitali yoyeretsa.

2.3 Njira zakuthupi-zamankhwala

• Kusinthana kwa Ma Ion : Ma resin osinthana ma Ion omwe ali ndi ntchito zinazake amatha kunyamula ma ions a cyanide m'madzi otayira. Ma resin awa ali ndi magulu ogwira ntchito omwe amatha kuyanjana ndi ma ions a cyanide. Ma resin akadzazidwa ndi ma ions a cyanide, amatha kubwezeretsedwanso ndi othandizira okonzanso oyenera, ndipo ma ions a cyanide amatha kubwezeretsedwanso kapena kuthandizidwanso. Kusinthana kwa ma Ion kumakhala ndi kusankha kwakukulu komanso kogwira ntchito bwino, koma mtengo wa ma resin ndi othandizira okonzanso uyenera kuganiziridwa, ndipo chithandizo cha zinyalala zokonzanso chimafunikanso kusamalidwa.

• Kulekanitsa Ma Nembrane : Ukadaulo wolekanitsa ma Nembrane, monga reverse osmosis ndi nanofiltration, ukhoza kulekanitsa ma ayoni a cyanide ndi madzi otayira pogwiritsa ntchito njira yosankha yolowera ma nembrane. Njirayi imatha kuchotsa bwino cyanide ndi zinthu zina zoipitsa, ndipo madzi okonzedwa bwino ndi abwino. Komabe, kulekanitsa ma nembrane kumakhala ndi mavuto owononga nembrane, zomwe zimafuna kutsukidwa nthawi zonse ndi kukonzedwa kwa nembrane, zomwe zimawonjezera ndalama zogwirira ntchito.

3. Njira Yochiritsira Yonse

3.1 Kuchiza

Asanayambe kulandira chithandizo, madzi onyansa okhala ndi cyanide ochokera ku michira ya cyanide ayenera kukonzedwa kale. Gawoli limaphatikizapo kuchotsa zolimba zazikulu zoyimitsidwa, kusintha pH yamadzi otayira, ndikuletsa zinthu zina zomwe zingasokoneze njira zotsatsira. Mwachitsanzo, kugwiritsa ntchito matanki otayira kutha kuchotsa zolimba zomwe zayimitsidwa, ndipo kuwonjezera asidi kapena alkali yoyenera kutha kusintha pH yamadzi otayira kuti ikhale yoyenera kuti athandizidwe pambuyo pake.

3.2 Chithandizo Chachikulu

Malingana ndi njira yosankhidwa yochizira, madzi otayira omwe amaikidwa kale amalowa mu gawo lalikulu la mankhwala. Ngati ntchito mankhwala makutidwe ndi okosijeni, ndi okosijeni lolingana ndi anawonjezera malinga ndi masamu mlingo, ndi zimene ikuchitika mu thanki anachita ndi oyambitsa koyenera kuonetsetsa kukhudzana mokwanira pakati pa okosijeni ndi cyanide. Pankhani ya chithandizo chachilengedwe, madzi onyansa amalowetsedwa mu chipangizo chopangira mankhwala, ndipo magawo ogwiritsira ntchito chipangizocho amasinthidwa kuti asunge malo abwino kwambiri akukula kwa tizilombo. Kwa njira zamagetsi zamagetsi, madzi onyansa amadutsa m'mizere yosinthira ion kapena zida zolekanitsa membrane kuti akwaniritse kulekanitsa ndi kuchotsedwa kwa cyanide.

3.3 Pambuyo pa Chithandizo

Pambuyo pa chithandizo chachikulu, chithandizo cham'mbuyo chimafunika kuti mupitirize kuyeretsa madzi oyeretsedwa ndikuwonetsetsa kuti akukwaniritsa miyezo yotuluka. Kuchiza pambuyo pake kungaphatikizepo njira monga kuchotsanso zowononga zotsalira zotsalira, kusintha zizindikiro za khalidwe la madzi (monga kusintha pH kachiwiri, kuchepetsa kufunikira kwa okosijeni wa makemikolo), ndi kupha tizilombo toyambitsa matenda. Madzi oyeretsedwa amafunika kuyesedwa ndikuyesedwa nthawi zonse kuti atsimikizire kuti ubwino wake ukukwaniritsa zofunikira zotetezera chilengedwe.

4. Mfundo zazikuluzikulu ndi Zomwe Zidzachitike M'tsogolo

Panthawi ya chithandizo, ndikofunikira kuyang'anira chitetezo cha ogwira ntchito kuti apewe poizoni wa cyanide. Panthawi imodzimodziyo, kusankha njira ndi njira zothandizira ziyenera kuganizira mozama zinthu monga mtengo wa mankhwala, chithandizo chamankhwala, ndi momwe chilengedwe chikuyendera. M'tsogolomu, ndikusintha kosalekeza kwa zofunikira pachitetezo cha chilengedwe, kafukufuku ndi chitukuko chaukadaulo wowongolera bwino, wokonda zachilengedwe, komanso wotsika mtengo wokhala ndi cyanide wokhala ndi madzi otayira adzakhala njira yachitukuko. Mwachitsanzo, kuphatikiza njira zingapo zochizira, kupanga zopangira zatsopano ndi zida za okosijeni wamankhwala, komanso kukhathamiritsa kwa njira zochiritsira zachilengedwe kuti zipititse patsogolo kuwonongeka kwa cyanide.

Pomaliza, kuchiritsa madzi onyansa okhala ndi cyanide kuchokera ku michira ya cyanide ndi ntchito yovuta koma yofunika. Pomvetsetsa ndi kugwiritsa ntchito njira ndi njira zochiritsira zoyenera, ndikufufuza mosalekeza ndi kupanga zatsopano, tingathe kuthetsa vuto la kuipitsidwa kwa cyanide, kuteteza chilengedwe, ndikulimbikitsa chitukuko chokhazikika cha migodi.
