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 zvakakosha zvakanakira. Iyo kambani inodyara huwandu hwakakura hwezviwanikwa mukutsvagisa tekinoroji uye kusimudzira, uye inopa yakazara tekinoroji rutsigiro kune zvingangoitika matambudziko ezvakatipoteredza anogona kumuka panguva yekugadzira, kutakura, kuchengetedza uye kushandiswa. Sodium cyanide. Chikwata chedu chehunyanzvi chinogona kubatsira mabhizinesi emuno muKazakhstan kumisikidza yakazara nharaunda manejimendi system uye kuderedza kusvibiswa chizvarwa kubva kunobva. Semuenzaniso, mukugadzira, tinotora tekinoroji yakasvibira synthesis yekuvandudza mashandisirwo emidziyo 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:

• Alkaline Chlorination Method: Iyi inzira yakajairika yekuparadza Cyanides mumvura yetsvina yegoridhe cyanidation zvidyarwa uye inoshandiswa zvakanyanya mukuchenesa mvura yecyanide electroplating zvidyarwa, goridhe mine cyanidation zvidyarwa, goridhe cyanidation zvidyarwa uye zvimwe zvikamu. Chirevo chayo ndechekushandisa liquid chlorine, chlorine gasi kana bleaching poda kuita oxidize cyanide iri mumvura yetsvina kuita zvisina muchetura zvinhu zvakaita secarbon dioxide nenitrogen.

• Sulfur Dioxide - Mhepo Oxidation Nzira: Iyo inozivikanwawo seInCo nzira, yakagadzirwa neAmerican InCo Metals Company mukutanga kwema1980. Iyi nzira inoshandisa sulfur dioxide nemhepo seoxidants kuti iite oxidize macyanides mumvura ine tsvina pasi pemamiriro emhangura - ion catalyst, inogadzira bicarbonate uye ammonium ferrous sulfate. Haikwanise chete kubvisa mahara cyanide ions, molecular hydrogen uye yakaoma cyanides, asiwo kubvisa ferrocyanide complexes iyo yakaoma kubvisa nenzira yeklorination, zvichiita kuti mvura yakasvibiswa yakagadziriswa isangane nemitemo yekubuda.

• Hydrogen Peroxide Oxidation Nzira: Inokodzera kurapa yakaderera - concentration cyanide - ine tsvina yemvura. Pasi pekuita kwemhangura - ion catalyst pa alkaline pH kukosha kwe 10 - 11. hydrogen peroxide inogadzirisa cyanides kuti ibudise zvinhu zvemakemikari zvakadai seokisidhi uye ammonium ferrous sulfate. Pakati pavo, heavy metal ions inogadzira hydroxide precipitates, uye ferrocyanide ions nemamwe maion anorema esimbi anoumba ferrocyanide yakaoma munyu.

• Ozone Oxidation Nzira: Yakakodzera kurapa ine dilute cyanide - ine tsvina yemvura. Pa alkaline pH kukosha kwe 11 - 12. ozone oxidize ma cyanides kugadzira bicarbonate ne nitrogen. Kunyangwe iyi nzira isingakwanise kubvisa ferrocyanide complexes, ine zvakanakira zvekureruka uye nyore. Hapana chikonzero chekutenga nekutakura makemikari, uye chete ozone jenareta inodiwa kurapa cyanide - ine tsvina yemvura. Zvisinei, inewo zvipingamupinyi zvekushandiswa kwemasimba makuru uye mari yekurapa yakakwirira. Kugadzirisa dambudziko referrocyanide complexes, Tinker Air Force Base muUnited States yakagadzira nzira yakabatanidzwa ye ultraviolet photolysis uye ozone nzira uye yakabudirira kuiedza. 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.
