Tsvagiridzo yeCyanide-Ine Wastewater Kurapwa uye Kudzoreredza Kudzoreredza Kwezvinhu Zvinokosha

Munzvimbo yekuvandudzwa kwemaindasitiri emazuva ano, kugadzirwa kwemvura yakasviba ine cyanide chinhu chisingadzivisike muzvikamu zvakasiyana-siyana, zvinosanganisira migodhi, electroplating, uye kugadzirwa kwemakemikari. Mvura iyi yakasviba haingori chete njodzi huru kunharaunda yezvakatipoteredza uye hutano hwevanhu nekuda kwehunhu hwayo hune chepfu yakawanda asiwo ine zvinhu zvinokosha zvinogona kuwanikwa, zvichipa mabhenefiti ezvakatipoteredza nehupfumi. Nekuda kweizvozvo, tsvakiridzo yekurapa mvura yakasviba ine cyanide uye kudzoserwa kwakakwana kwezvinhu zvinokosha yave nyaya yakakosha inokwezva kutariswa kukuru kubva kuvadzidzi nemaindasitiri.

Kusimba kweCyanide-Ine Mvura Yakasviba

Cyanide chinhu chine muchetura zvakanyanya chinogona kukanganisa zvakanyanya kushanda kwakajairwa kwemuviri wemunhu wekufema uye tsinga masisitimu kunyangwe pakudzika kwakadzika. Kana mvura ine tsvina ine cyanide ikaiswa mumitumbi yemvura yakasikwa isina kurapwa kwakakodzera, inogona kutungamira kurufu rwezvipenyu zvemumvura, kuparadza kuenzana kwezvakatipoteredza zvezvipenyu zvemvura, uye kusvibisa ivhu nemvura yepasi kuburikidza nekuyerera, zvichikonzera kuparara kwenguva refu uye kure kure kwezvakatipoteredza. Pamusoro pezvo, kubva pamaonero ehupfumi, kuraswa zvisina kufanira kwemvura ine tsvina ine cyanide kunoreva kutambisa zviwanikwa zvakakosha, sesimbi dzakakosha segoridhe, sirivheri, uye simbi dzinorema semhangura, zinc, iyo inowanzovapo mumvura yakasviba yakadaro.

Advanced Treatment Technologies yeCyanide-Ine Wastewater

Kemikari Oxidation Nzira

Kucheneswa kwemakemikari ndeimwe yenzira dzinonyanya kushandiswa pakurapa mvura yakasviba ine cyanide. Maitiro akadai se chlorination, ozonation, uye kushandiswa kwehydrogen peroxide anoshandiswa zvakanyanya. Semuenzaniso, chlorination inoshandisa chlorine kana zvinhu zvayo kucheneswa kwecyanide kuita maion asina chepfu, uye wozowedzera kuacheneswa muCarbon dioxide nenitrogen mumamiriro ezvinhu akakodzera. Ozonation, nekugona kwayo kukuru kwe oxidizing, inogona kukurumidza kuparadza cyanide, uye reaction yacho inenge yakakwana, ichisiya tsvina shoma. Nzira idzi dze chemical oxidation dzinogona kuderedza huwandu hwecyanide mumvura yakasviba, zvichiita kuti isvike padanho rekubuda.

Biological Treatment Nzira

Biological kurapwa kunoshandisa tupukanana kuita metabolize uye kuora cyanide. Mabhakitiriya chaiwo anogona kuenderana nenharaunda ine cyanide uye kushandisa cyanide sekabhoni sosi uye nitrogen sosi yekukura nekubereka. Iyi nzira ine zvakanakira mutengo wakaderera, hushamwari hwezvakatipoteredza, uye kugona kubata yakawanda yakawanda yemvura yakaraswa nguva dzose. Nekudaro, inonzwa kune zvinhu zvakaita setembiricha, pH kukosha, uye kuvapo kwezvinhu zvinodzivirira mumvura yetsvina, izvo zvinoda kudzora kwakasimba kwemamiriro ekushanda.

Muviri-Chemical Kurapa Nzira

Nzira dzemakemikari, dzinosanganisira kunyungudutsa, kuchinjana kwemaion, uye kupatsanurwa kwema membrane, dzinoitawo basa rakakosha mukurapa mvura yakasviba ine cyanide . Kunyungudutsa kwekabhoni kunogona kubvisa cyanide yakasara nezvimwe zvinosvibisa mumvura yakasviba. MaIon exchange resins anogona kunyungudutsa maion ecyanide uye metal-cyanide complexes nenzira yakasarudzika, zvichiita kuti cyanide iparadzwe uye iwedzere kunaka. Tekinoroji yekuparadzanisa membrane, senge reverse osmosis uye nanofiltration, inogona kuparadzanisa cyanide nezvinhu zvinokosha kubva mumvura yakasviba kuburikidza nema membranes anopindirana zvishoma nezvishoma, nekushanda kwakanyanya kwekuparadzanisa uye kugadzikana kwakanaka.

Kudzoreredza Kwakazara Kwezvinhu Zvinokosha

Kudzorerwa Kwesimbi Anokosha

Mumigodhi uye maindasitiri e electroplating, mvura ine tsvina ine cyanide kazhinji ine simbi dzinokosha segoridhe nesirivha. Matekinoroji akadai sekubvisa solvent, electrowinning, uye ion exchange anowanzo shandiswa pakupora kwavo. Solvent kudonhedzwa kunoshandisa organic zvinonyungudutsa kuti zvisarudze kubvisa akakosha simbi-cyanide complexes kubva mumvura ine tsvina, zvichiteverwa nekubvisa uye kunaya kwemvura kuti uwane simbi dzinokosha. Electrowinning inodzosa simbi kubva mumvura yakasviba kuburikidza ne electrolysis, iri nyore uye inoshanda nzira yekudzoreredza simbi.

Kudzorerwa Kwesimbi Inorema

Kune simbi dzinorema semhangura uye zingi mumvura ine tsvina ine cyanide, nzira dzakaita sekunaya kwemakemikari, simende, uye kunyungudutsa kunogona kuiswa. Kunaya kwemakemikari kunoshandisa reagents kuita neheavy metal ions kuumba mvura isinganyungudika, inozopatsanurwa. Cementation inoshandisa mamwe masimbi emagetsi kudzinga simbi dzinorema kubva mumhinduro, kuwana kupora. Idzi nzira dzekudzoreredza hadzingodzikisi kusvibiswa kwezvakatipoteredza kunokonzerwa nesimbi dzinorema asiwo dzinoshandura marara kuita hupfumi, zvichigadzira kukosha kwehupfumi.

Matambudziko Nezvinotarisirwa

Kunyangwe kufambira mberi kwakanyanya mukurapa kwemvura ine tsvina ine cyanide uye kudzoreredzwa kwezvinhu zvakakosha, kuchine matambudziko mazhinji. Semuenzaniso, kudhura kwakanyanya kwemamwe matekinoroji epamusoro ekurapa, kuomarara kwekuchenesa mvura ine zvikamu zvakaoma, uye kuomerwa kwekuona kugadzikana kwenguva refu kwemaitiro ekurapa. Mune ramangwana, vatsvakurudzi vanofanira kuisa pfungwa pakuvandudza hutano hwakanaka, husingadhuri, uye hushamwari hwezvakatipoteredza hwakabatanidzwa kurapwa uye kupora matekinoroji. Iko kusanganiswa kwemaitiro akawanda ekurapa, kuvandudzwa kwekuita kwezvinhu, uye kushandiswa kwehungwaru hwekunyepedzera uye data hombe mukudzorwa kwemaitiro zvingangove nzira dzakakosha dzebudiriro, zvichibatsira mukusimudzirwa kwemaindasitiri uku uchichengetedza nharaunda.

Mukupedzisa, tsvakiridzo yekurapwa kwemvura yetsvina ine cyanide uye kudzoreredza kuzere kwezvinhu zvakakosha kwakakosha zvikuru pakuchengetedza kwezvakatipoteredza, kushandiswa kwezviwanikwa, uye kusimudzira hupfumi. Kuenderera mberi kwekuongorora uye hunyanzvi mundima iyi kuchaunza mamwe maitiro akanaka pane ese ecology nharaunda uye hupfumi hweindasitiri.
