Shaanxi United Chemical: Te whakarato i nga otinga konutai kakariki mo Kazakhstan

I roto i te mara o te supply hua matū, Shaanxi United Chemical kua noho tonu ki mua o te ahumahi me te ahua ngaio me te kawenga. Inaianei, kua tino whakanuia matou ki te whakarato i te kounga teitei konutai Cyanide nga hua mo Kazakhstan.

Te konutai tina, hei rauemi mata matū nui, e whakamahia whānuitia ana i roto i te maha o nga mara ahumahi, ina koa i roto i te keri koura me te umanga whaihua. Heoi, na te mea ko ona taonga motuhake, ka tino whakahaeretia e te kawanatanga o Haina. Kei te tino mohio ano matou ki te kino o te kino konutai cyanide ki te taiao. Mena karekau te cyanide - he wai para i hangaia i roto i te keri koura me te mahi whakangao, ka waiho hei morearea taiao. Ko te cyanide i roto i te wai para o nga tipu cyanidation koura ka whakatauhia e te hanganga o te ore me nga tikanga whakahaere. I tua atu i te cyanide, kei roto ano he matū matū penei i te thiocyanate. Ko te nuinga o enei thiocyanates i ahu mai i te tukanga aeration i roto i te whakaputanga, i te tauhohenga ranei i waenga i te cyanide me nga ngota whanariki kore e mau i te wa e rewa ana. I tua atu, ko te cyanide - kei roto i te wai para he maha nga kohinga cyanide whakarewa tino paitini me hauhaua. No reira, Shaanxi United Chemical ehara i te mea he kaiwhakarato hua engari he kaimahi ano hoki Parenga taiao.

Nga Painga Tiaki Taiao

Mō te tiaki taiao, he nui ā mātou painga. He nui ngā rauemi e whakangaohia ana e te kamupene ki te rangahau me te whanaketanga hangarau, ā, e whakarato ana i te tautoko hangarau whānui mō ngā raruraru taiao ka puta ake i te wā e whakaputa ana, e kawe ana, e penapena ana me te whakamahi i te Sodium cyanide . Ka taea e tā mātou tīma ngaio te āwhina i ngā umanga ā-rohe i Kazakhstan ki te whakatū i tētahi pūnaha whakahaere taiao katoa me te whakaiti i te whakaputanga parahanga mai i te pūtake. Hei tauira, i roto i te tukanga whakaputa, ka whakamahia e mātou ngā hangarau whakahiato matomato matatau hei whakapai ake i te whakamahinga o ngā rauemi mata me te whakaiti i ngā tukunga para.

Nga Tikanga Maimoatanga mo te Cyanide - kei roto te Waipara

I roto i te maimoatanga o te cyanide - kei roto te wai para i roto i te keri koura me te umanga whaihua, he maha nga momo tikanga pakeke me te whai hua ka mohio matou:

• Tikanga Whakakōkōwaiwai Kawakore : He tikanga noa tēnei mō te whakangaro i ngā Cyanide i roto i te wai para o ngā tipu whakakōkōwaiwai koura, ā, e whakamahia whānuitia ana i roto i te maimoatanga wai para o ngā tipu whakakikorua hiko cyanide, ngā tipu whakakōkōwaiwai maina koura, ngā tipu whakakōkōwaiwai koura me ētahi atu wāhanga. Ko tōna kaupapa matua he whakamahi i te chlorine wai, te hau chlorine, te paura whakama ki te whakawairakau i te cyanide i roto i te wai para hei matū kore-paitini pērā i te hauhā me te hauota.

• Tikanga Whakahāngai Hauhā - Te Hāngai Hauā : ​​E mōhiotia ana ko te tikanga InCo, i whakawhanakehia e te Kamupene Metara InCo o Amerika i te tīmatanga o te tekau tau atu i 1980. Ka whakamahia e tēnei tikanga te hāngai hauhā me te hau hei whakahāngai hauā hei whakahāngai i ngā cyanide i roto i te wai para i raro i te āhua o te whakakorikori parahi-iona, e whakaputa ana i te paikāponate me te ammonium ferrous sulfate. E kore e taea anake te tango i ngā iona cyanide kore utu, te hauwai ngota me ngā cyanide matatini, engari ka whakakorea hoki ngā matatini ferrocyanide e uaua ana ki te tango mā te tikanga whakakōkō, kia tutuki ai te wai para kua tukatukahia ki ngā paerewa tukunga.

• Tikanga Whakahāngaitanga Hauwai Peroxide : He pai mō te rongoā i ngā wai para kei roto he cyanide he iti te kukū. I raro i te mahi a te whakakorikori ira parahi i te pH kawakore o te 10 - 11, ka whakahāngaitia ngā cyanide e te hauwai peroxide hei whakaputa i ngā matū pēnei i ngā waikura me te ammonium ferrous sulfate. I roto i ēnei, ka hangaia e ngā ira konganuku taumaha ngā matū waikura, ā, ka hangaia e ngā ira ferrocyanide me ētahi atu ira konganuku taumaha he tote matatini ferrocyanide.

• Tikanga Whakahāora Ozone : He pai mō te rongoā i ngā wai para kei roto te cyanide he waimeha noa iho. I te pH kawakore o te 11 - 12, ka whakahāorahia e te ozone ngā cyanide hei whakaputa i te paikāponate me te hauota. Ahakoa kāore e taea e tēnei tikanga te tango i ngā matū ferrocyanide, he pai ōna, he ngāwari hoki. Kāore he take ki te hoko me te kawe i ngā matū, ā, he kaihanga ozone anake e hiahiatia ana hei rongoā i ngā wai para kei roto te cyanide. Heoi, he ngoikoretanga anō hoki ōna, arā, he nui te whakamahinga hiko me te nui o ngā utu rongoā. Hei whakaoti i te raruraru o ngā matū ferrocyanide, i whakawhanakehia e te Tinker Air Force Base i te United States tētahi tukanga whakakotahi o te tikanga photolysis ultraviolet me te tikanga ozone, ā, i whakamatauria paitia. Nō muri mai, i whakawhanakehia anō hoki tētahi tikanga O3/photolysis rite.

Whakapumautanga mo te kawe me te rokiroki

I roto i te hononga kawe waka, kua rite ki a matou nga taputapu kawe matū morearea ngaio me nga tikanga whakahaere mo te kawe waka kia pai ai te taenga mai o te konutai cyanide ki te taunga me te whakaiti i te paanga ki te taiao i runga i te huarahi. Mo te taha o te rokiroki, ka tukuna e matou he rongoa rongoa rongoa me nga whakaurunga hei aukati i nga aitua penei i te rerenga mai i te poke i te oneone me nga puna wai. I nga ahuatanga ohorere, kei a matou ano nga hangarau maimoatanga ohorere ngaio me nga roopu ka taea te whakautu tere me te whakaiti i te kino o te taiao.

Shaanxi United Chemical kei te kaha ki te mahi tahi me nga hoa mahi i Kazakhstan ki te whakatutuki i te whanaketanga kaakaariki me te tauwhiro i te wa e whakarato ana i nga hua konutai cyanide kounga teitei. E whakapono ana matou ma o maatau mahi, ka taea e matou te whai waahi ki te whakawhanaketanga ahumahi o Kazakhstan me te taapiri i te taurangi mo te tiaki taiao o te rohe.
