Tsvagiridzo uye Kushandiswa kweSodium Cyanide Pollution Control Technologies

ziviso

Sodium cyanide ikemikari ine muchetura yakanyanya kushandiswa mumaindasitiri akasiyana siyana semigodhi, electroplating, uye makemikari synthesis. Nekudaro, kubata kwayo nekurasa zvisina kunaka kunogona kukonzera kusvibiswa kwezvakatipoteredza uye kuisa njodzi huru kune hutano hwevanhu uye ecological system. Nekuda kweizvozvo, kuvandudza uye kushandiswa kweiyo inoshanda Sodium cyanideKudzora kusvibiswa matekinoroji ave nzvimbo yakakosha yekutsvagisa uye kuita.

Traditional Treatment Nzira dzeSodium Cyanide Pollution

Alkaline Chlorination

Kuisa chlorination mu alkaline ndeimwe yenzira dzinonyanya kushandiswa pakurapa mvura yakasviba ine cyanide. Mukuita uku, chlorine kana chlorine ine makemikari (akadai se sodium hypochlorite) anowedzerwa mumvura yakasviba pasi pemamiriro e alkaline. Kuita uku kunoitika mumatanho maviri. Kutanga, cyanide inosanganiswa kuita cyanogen chloride, uye ipapo cyanogen chloride inosanganiswa kuita cyanate. Pakupedzisira, maion e cyanate anowedzerwa hydrolyze kuti agadzire ammonia uye kabhoniMaitikiro echinyakare ealkaline chlorination anowanzoda pH yakakwira inosvika 10.5 uye mukana wekuderedza oxidation (ORP) we + 600 mV. Zvisinei, inzira inoshandisa makemikari akawanda, inoshandisa sodium hypochlorite yakawanda. Semuenzaniso, magaroni angangoita 23 e12.5% ​​sodium hypochlorite solution anodiwa kuparadza ounce imwe chete yecyanide.

Biological Treatment

Biological treatment yecyanide - ine tsvina yemvura inosanganisira kushandiswa kwehutachiona hwehutachiona. Mabhakitiriya eAerobic akadai sePseudomonas, Alcaligenes, uye Achromobacteria anogona oxidize cyanide kuita cyanate. Zvadaro, iyo cyanate ion inoshandurwa biologically kuita ammonia uye bicarbonate. Iyi nzira inoshanda kana cyanide concentration mumvura yetsvina yakaderera. Nekudaro, zvinoda kunyatso kudzora mamiriro ezvakatipoteredza senge tembiricha, pH, uye kuvapo kweakakodzera zvinovaka muviri kuti ive nechokwadi chekukura uye kuita kwehutachiona.

Acidification Method

Iyo acidification nzira inzira yechinyakare yekurapa yakakwira - concentration cyanide - ine tsvina yemvura mumaindasitiri akaita semigodhi yegoridhe uye cyanide electroplating. Nenzira iyi, mvura yetsvina inoiswa acidified kuti ibudise hydrogen cyanide gasi, iyo inokwanisa kudzoserwa kana kurapwa zvakare. Iyi nzira ine mukana wekukwanisa kudzoreredza cyanide kubva mumvura yakasviba, asi inoda kunyatsobata yakaburitswa hydrogen cyanide gasi kudzivirira kusvibiswa kwezvakatipoteredza uye kuve nechokwadi chekuchengetedzwa.

New Technologies yeSodium Cyanide Pollution Control

Yepamberi Oxidation Matanho (AOPs)

Yepamberi oxidation maitiro, senge ozone oxidation uye ultraviolet (UV) - catalyzed oxidation, yakaratidza kugona kukuru mukurapa Sodium Cyanide - mvura yakasvibiswa. Ozone oxidation inogona kunyatsoora cyanide kuita zvinhu zvishoma zvinokuvadza. Iyo ozone molecule inopindirana ne cyanide, ichipwanya zvisungo zvekemikari uye kuishandura kuita makomisheni akagadzikana. UV - catalyzed oxidation, kune rumwe rutivi, inowanzo shandisa zvinokonzeresa musanganiswa ne ultraviolet mwenje uye oxidants senge hydrogen peroxide. Semuenzaniso, muUV - H₂O₂ system, iyo ultraviolet mwenje inobatisa iyo hydrogen peroxide, ichigadzira yakanyanya reactive hydroxyl radicals inogona kukurumidza kushatisa cyanide. Aya maitiro anowanzo shanda uye anogona kuwana yakaderera yasara cyanide concentrations zvichienzaniswa nemaitiro echinyakare.

Nanotechnology - based Approaches

Nanotechnology iri kubuda sendima inovimbisa yekuvandudza cyanide pollution control. Nanomaterials, senge nanocatalysts, inogona kuwedzera maitiro ekuita kweiyo cyanide degradation process. Semuenzaniso, mamwe simbi - based nanocatalysts anogona kusimudzira oxidation ye cyanide pasi pemamiriro akanyorova. Uyezve, nanofiltration membranes inogona kushandiswa kuparadzanisa cyanide uye zvimwe zvinosvibisa kubva mumvura. Aya ma membrane ane pores mune nanometer renji, achibvumira kubviswa kunobudirira kwemamorekuru madiki uye ion, kusanganisira cyanide, ichichengeta zvinhu zvakakosha uye kuderedza huwandu hwemarara anogadzirwa.

Mamiriro ekushandisa eSodium Cyanide Pollution Control Technologies

MuMigodhi Indasitiri

Mukuchera goridhe, kupi sodium cyanide inowanzoshandiswa pakuchera goridhe, tekinoroji dzekudzora kusvibiswa dzakanyanya kukosha. Semuyenzaniso, mamwe mabasa makuru ekuchera migodhi atora musanganiswa wealkaline chlorination uye kurapwa kwebiological. Chekutanga, iyo alkaline chlorination process inoshandiswa kudzikisa iyo yakakwira -concentration cyanide mumvura yetsvina yekumisa kune imwe nhanho. Zvadaro, mvura yetsvina inorapwazve biologically kuti isangane neyakaomarara yekuburitsa nharaunda. Mune zvimwe zviitiko, matekinoroji matsva seUV - catalyzed oxidation ari kuedzwa zvakare. Migodhi iri munzvimbo dzisingatarisirwi nemhoteredzo inonyanya kukurudzirwa kutora matekinoroji epamusoro uye anoshanda zvakanyanya ekudzora kusvibiswa kwemamiriro ekunze kuti kuderedze kukanganisa kunharaunda yakapoteredza.

In Industrial Wastewater Treatment

Maindasitiri eElectroplating anoshandisa cyanide - based plating mabhati anoburitsawo huwandu hwakakura hwecyanide - ine tsvina. Zvizhinji zvemazuva ano zvinomera zve electroplating zvakaisa pane - saiti tsvina yekurapa zvivakwa. Vanowanzoshandisa matanho ekurapwa, kutanga nekunaya kwesimbi inorema yakabatana ne cyanide complexes, inoteverwa nekuparadzwa kwe cyanide yakasununguka vachishandisa nzira dzakadai sealkaline chlorination kana maitiro ekugadzirisa oxidation. Zvimwe zvidyarwa zvakaisawo masisitimu anoenderera mberi ekuona kuti mvura yetsvina yakacheneswa inosangana nezvinodiwa nemutemo isati yaiswa musewer system kana pamusoro pemvura.

Matambudziko uye Maonero Anouya

Zvisinei nekuvepo kweakasiyana siyana sodium cyanide pollution control tekinoroji, matambudziko akati wandei aripo. Rimwe rematambudziko makuru mutengo wakakwira une chekuita nehumwe matekinoroji ekurapa, kunyanya kumabhizinesi madiki - uye epakati -. Pamusoro pezvo, kurapwa kwecyanide yakaoma - ine tsvina yemvura, inogona kunge iine musanganiswa wemakomboni ecyanide nezvimwe zvinosvibisa, inoda nzira dzekurapa dzinoshanda uye dzakasiyana.

Tichitarisa kune ramangwana, kumwe kutsvagisa nekusimudzira kunodiwa kuti uvandudze mashandiro uye mutengo - kushanda kwehunyanzvi huripo. Izvi zvinogona kusanganisira kukwidziridzwa kwemamiriro ekuita, kukudziridzwa kwezvakagadzikana uye zvinobudirira zvinokonzeresa, uye kubatanidzwa kwemaitiro akasiyana ekurapa. Uyezve, kuongororwa kwemaitiro matsva uye ehutsva ekurapa, akadai sekushandiswa kwemajini enjiniya ma microorganisms ekuwedzeredzwa kwe cyanide kana kushandiswa kwezvinhu zvitsva zvine hunhu hwakasiyana hwekubvisa cyanide, kune chivimbiso chikuru chekuwedzera inoshanda sodium cyanide kusvibiswa kwekudzora mukufamba kwenguva.

Mukupedzisa, kutsvagisa uye kushandiswa kwesodium cyanide kudzora kusvibiswa tekinoroji kwakakosha mukuchengetedza nharaunda uye hutano hwevanhu. Kuenderera mberi kwekuvandudza uye kuvandudzwa kwematekinoroji aya kuchaita basa rakakosha mukusimudzirwa kwemaindasitiri uye kuchengetedza kwezvakatipoteredza.
