Tsvagiridzo yeCyanide-Ine Wastewater Kurapwa uye Kudzoreredza Kudzoreredza Kwezvinhu Zvinokosha

Munzvimbo yekuvandudzwa kwemaindasitiri emazuva ano, chizvarwa che cyanide-ine tsvina yemvura chinhu chisingadzivisiki chinogadzirwa muzvikamu zvakasiyana, kusanganisira migodhi, electroplating, uye kugadzira makemikari. Mvura yetsvina iyi haingokonzerese kutyisidzira kwezvakatipoteredza uye hutano hwevanhu nekuda kwehupfu hwecyanide asi ine zvinhu zvakakosha zvinogona kudzoserwa, zvichipa zvese zvakatipoteredza nehupfumi. Nekuda kweizvozvo, tsvagiridzo yekurapwa kwemvura yetsvina ine cyanide uye kudzoreredza kudzoreredza kwezvinhu zvakakosha yave musoro wakakosha unokwezva kutarisisa kukuru kubva kuvadzidzi neindasitiri.

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 kucheneswa. kabhoni dioxide nenitrogen mumamiriro ezvinhu akakodzera. Ozonation, nekukwanisa kwayo kukuru kwe oxidizing, inogona kukurumidza kuparadza cyanide, uye kuita kwayo kwacho kwakazara, zvichiita kuti pave nekusvibiswa kushoma. Nzira idzi dzemakemikari dzinogona kuderedza huwandu hwe cyanide 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 dzemuviri-kemikari, kusanganisira adsorption, ion exchange, uye membrane kupatsanurwa, inoitawo basa rakakosha mune cyanide-ine. kurapwa kwemvura yakasviba. Activated kabhoni adsorption inogona kunyatsobvisa yakasara cyanide uye zvimwe organic zvinosvibisa mumvura yetsvina. Ion exchange resins inogona kusarudza adsorb cyanide ions uye metal-cyanide complexes, kuwana kupatsanurwa uye kupfumisa cyanide. Membrane separation tekinoroji, senge reverse osmosis uye nanofiltration, inogona kupatsanura cyanide uye zvinhu zvakakosha kubva mumvura yakaraswa kuburikidza nesemi-permeable membranes, ine yakanyanya kuparadzanisa kugona 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.
