Tsvagiridzo uye Kushandiswa kweSodium Cyanide Pollution Control Technologies

ziviso

Sodium cyanide ikemikari ine chepfu yakawanda inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana akadai sekuchera, kugadzira mapurasitiki, uye kugadzira makemikari. Zvisinei, kusabatwa kwayo zvakanaka uye kuraswa kwayo kunogona kukonzera kusvibiswa kwakanyanya kwezvakatipoteredza uye kunokonzera njodzi huru kuhutano hwevanhu uye masisitimu ezvakatipoteredza. Nekuda kweizvozvo, kugadzirwa nekushandiswa kweSodium cyanide inoshanda. Tekinoroji dzekudzora kusvibiswa kwemhepo dzave nzvimbo yakakosha yekutsvagisa nekuita.

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 inoiswa mu cyanogen chloride, uye cyanogen chloride inoisa hydrolyzes kuti igadzire cyanate. Pakupedzisira, maion e cyanate anoiswa mu hydrolyzes kuti agadzire ammonia neCarbon ates . Maitiro e alkaline chlorination echinyakare anowanzoda pH yakakwira inosvika 10.5 uye high oxidation - reduction potential (ORP) ye + 600 mV. Zvisinei, inzira inoshandisa makemikari akawanda, inoshandisa sodium hypochlorite yakawanda. Semuenzaniso, magaroni angangoita 23 e 12.5% ​​sodium hypochlorite solution anodiwa kuparadza ounce imwe chete ye cyanide.

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)

Maitiro epamusoro e oxidation, akadai se ozone oxidation uye ultraviolet (UV) - catalyzed oxidation, akaratidza kugona kukuru mukurapa Sodium Cyanide - mvura yakasvibiswa. Ozone oxidation inogona kuodza cyanide kuita zvinhu zvisingakuvadzi zvakanyanya. Ozone molecule inosangana ne cyanide, ichipwanya makemikari uye ichiishandura kuita macompounds akasimba. UV - catalyzed oxidation, kune rumwe rutivi, inowanzo shandisa ma catalysts pamwe chete ne ultraviolet light uye oxidants senge hydrogen peroxide. Semuenzaniso, muUV - H₂O₂ system, ultraviolet light inomutsa hydrogen peroxide, ichigadzira highly reactive hydroxyl radicals iyo inogona kukurumidza kuparadza cyanide. Maitiro aya anowanzo shanda uye anogona kuwana mashoma e residual cyanide concentrations zvichienzaniswa nenzira dzechinyakare.

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, uko sodium cyanide inowanzo shandiswa pakuchera goridhe, matekinoroji ekudzora kusvibiswa kwemhepo anonyanya kukosha. Semuenzaniso, mamwe mabasa makuru ekuchera goridhe akashandisa musanganiswa wealkaline chlorination uye kurapwa kwezvemhuka. Kutanga, maitiro ealkaline chlorination anoshandiswa kuderedza cyanide yakawanda mumvura yakasviba kusvika padanho rakati. Zvadaro, mvura yakasviba inorapwa zvakare nemakemikari emuviri kuti isangane nezvinodiwa zvekuchengetedza nharaunda. Mune zvimwe zviitiko, matekinoroji matsva akadai seUV-catalyzed oxidation ari kuyedzwawo. Migodhi iri munzvimbo dzine zvakatipoteredza inonyanya kukurudzirwa kushandisa matekinoroji epamusoro uye anoshanda zvakanyanya ekudzora kusvibiswa kwemhepo kuti aderedze kukanganisa kwezvakatipoteredza.

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.
