Shaanxi United Chemical: Kupa Green Sodium Cyanide Solutions yeKazakhstan

Mumunda wemakemikari chigadzirwa kupa, Shaanxi United Chemical yakagara iri pamberi peindastiri ine nyanzvi uye ine mutoro mufananidzo. Iye zvino, isu tine rukudzo rwekukwanisa kupa zvemhando yepamusoro Sodium Cyanide zvigadzirwa zveKazakhstan.

Sodium cyanide, sechinhu chakakosha chemakemikari mbishi, chinoshandiswa zvakanyanya muminda yakawanda yemaindasitiri, kunyanya mumigodhi yegoridhe uye indasitiri yekubatsira. Nekudaro, nekuda kwezvivakwa zvayo zvakakosha, inodzorwa zvakanyanya nehurumende yeChina. Isu tinoziva zvakare zvakadzama nezvekukuvadza kunogona kuitika kwe sodium cyanide kune zvakatipoteredza. Kana iyo cyanide - ine tsvina inogadzirwa mumugodhi wegoridhe uye kubatsiridza maitiro ikasabatwa nemazvo, inova njodzi huru yezvakatipoteredza. Iyo cyanide mumvura yakasvibiswa yemiti yegoridhe cyanidation inotarirwa nekuumbwa kwe ore uye mamiriro ekushanda. Mukuwedzera kune cyanide, inewo makemikari zvinhu zvakadai se thiocyanate. Mazhinji eaya thiocyanates anobva kuaeration process mukugadzira kana kuita pakati pecyanide uye isina kugadzikana maatomu esarufa panguva yeleaching. Uyezve, iyo cyanide - ine tsvina ine mvura yakawanda ine muchetura wesimbi cyanide complexes uye cyanides. Saka, Shaanxi United Chemical haasi chete mutengesi wezvigadzirwa asiwo mushandi we Environmental Protection.

Environmental Protection Advantages

Panyaya yekuchengetedzwa kwezvakatipoteredza, tine zvakanakira zvikuru. Kambani iyi inoisa mari yakawanda mukutsvaga nekugadzira tekinoroji, uye inopa rutsigiro rwakakwana rwehunyanzvi kumatambudziko ezvakatipoteredza anogona kumuka panguva yekugadzira, kutakurwa, kuchengetwa uye kushandiswa kweSodium cyanide . Chikwata chedu chehunyanzvi chinogona kubatsira mabhizinesi emuno muKazakhstan kugadzira sisitimu yakakwana yekutarisira zvakatipoteredza uye kuderedza kugadzirwa kwezvinosvibisa kubva kunobva. Semuenzaniso, mukugadzirwa, tinoshandisa matekinoroji epamusoro ekugadzira green synthesis kuti tivandudze kushandiswa kwezvinhu zvakabikwa uye kuderedza kuburitswa kwemarara.

Kurapa Nzira dzeCyanide - ine Wastewater

Mukurapa kwecyanide - ine tsvina mumugodhi wegoridhe uye indasitiri yekubatsira, isu tinokwanisa nzira dzakasiyana siyana dzakakura uye dzinoshanda:

• Nzira yeAlkaline Chlorination : Iyi inzira yakajairika yekuparadza Cyanides mumvura yakasviba yezvirimwa zvegold cyanidation uye inoshandiswa zvakanyanya mukurapa kwemvura yakasviba yezvirimwa zvecyanide electroplating, zvirimwa zvegold mine cyanidation, zvirimwa zvegold cyanidation nedzimwe nzvimbo. Nheyo yayo ndeyekushandisa liquid chlorine, chlorine gasi kana bleaching powder kuti oxidize cyanide mumvura yakasviba kuita zvinhu zvisina chepfu zvakaita secarbon dioxide nenitrogen.

• Nzira yeSulfur Dioxide - Air Oxidation : Inozivikanwawo seInCo method, yakagadzirwa neAmerican InCo Metals Company kuma1980 ekutanga. Nzira iyi inoshandisa sulfur dioxide nemhepo sema oxidants kuti ioxide ma cyanides mumvura yakasviba pasi pemamiriro e copper-ion catalyst, ichigadzira bicarbonate ne ammonium ferrous sulfate. Haingobvisi ma free cyanide ions, molecular hydrogen uye complex cyanides chete, asiwo inobvisa ma ferrocyanide complexes akaoma kubvisa ne chlorination method, zvichiita kuti mvura yakasviba yakarapwa isangane nezvinodiwa zvekuburitsa mvura.

• Nzira yeHydrogen Peroxide Oxidation : Yakakodzera kurapa mvura yakasviba ine cyanide yakaderera. Pasi pekushanda kwe copper-ion catalyst ine alkaline pH value ye10 - 11, hydrogen peroxide inooxidates ma cyanides kuti agadzire makemikari akadai se oxides ne ammonium ferrous sulfate. Pakati pawo, heavy metal ions dzinoumba hydroxide precipitates, uye ferrocyanide ions nedzimwe heavy metal ions dzinoumba ferrocyanide complex salts.

• Nzira yeOzone Oxidation : Yakakodzera kurapa cyanide yakasanganiswa - ine marara. Pa pH yealkaline ye11 - 12, ozone inooxidates macyanides kuti igadzire bicarbonate nenitrogen. Kunyangwe nzira iyi isingakwanise kubvisa ferrocyanide complexes, ine zvakanakira zvekureruka uye nyore. Hapana chikonzero chekutenga nekutakura makemikari, uye jenareta yeozone chete ndiyo inodiwa kurapa marara ane cyanide. Zvisinei, inewo zvayakaipira yekushandisa simba rakawanda uye mari yakawanda yekurapa. Kuti igadzirise dambudziko re ferrocyanide complexes, Tinker Air Force Base muUnited States yakagadzira nzira yakabatana ye ultraviolet photolysis uye ozone method uye yakaiedza zvinobudirira. Gare gare, nzira yakafanana yeO3/photolysis yakagadzirwawo.

Kutakurwa uye Kuchengeta Simbiso

Mune chekufambisa chinongedzo, takashongedzerwa nemichina yekufambisa yemakemikari ine ngozi uye yakasimba manejimendi ekufambisa kuti tive nechokwadi chekuti sodium cyanide inosvika kunzvimbo yakachengeteka uku ichideredza kukanganisa kwezvakatipoteredza munzira. Panyaya yekuchengetedza, tinopa zvigadziriso zvekuchengetedza zvesainzi uye zvivakwa zvekudzivirira tsaona dzakaita sekudonha kubva pakusvibisa ivhu uye zvitubu zvemvura. Kana paine mamiriro ezvinhu asingatarisirwi, isu zvakare tine nyanzvi dzekurapa kwechimbichimbi matekinoroji uye zvikwata zvinokwanisa kupindura nekukurumidza uye kuderedza kukuvadzwa kwezvakatipoteredza.

Shaanxi United Chemical yakazvipira kushanda takabatana maoko nevadyidzani muKazakhstan kuwana girinhi uye budiriro inoenderera apo ichipa emhando yepamusoro sodium cyanide zvigadzirwa. Isu tinotenda kuti kuburikidza nekuedza kwedu, tinogona kubatsira mukusimudzira indasitiri yeKazakhstan uye nekuwedzera vimbiso yekuchengetedzwa kwenharaunda.
