Iyo yekudhaya yakasviba mvura inogadzirwa neyemachira chigayo iri kushatisa zvakanyanya kune zvakatipoteredza. Naizvozvo, mvura yemvura yakasviba inoda kurapwa isati yaburitswa kana kudzokororwazve. Ozone inosimba yakasimba kwazvo uye inoita basa rakakosha pakurapa kwemvura yakasviba.
Kudhinda uye kudhaya mvura yakasviba imvura yeindasitiri ine hroma hombe, yakakwira organic uye yakaoma kuumbwa. Mvura zvakare ine huwandu hwakawanda hwemasara akasara, alkalis, diazo, azo, nezvimwewo, izvo zvinonetsa kubata. Mvura yakasviba yemachira inowanzo kurapwa mumatanho matatu:
Kutanga: kurapwa kwepanyama, kwakaparadzaniswa ne sedimentation uye grid kusefa;
Chechipiri: kurapwa kwemakemikari, kuwedzera makemikari vamiririri kunatsiridza mhando yemvura;
Chechitatu: advanced kurapwa, uchishandisa ozone oxidation tekinoroji , zvinobudirira kudzikisa COD, BOD tsika, uye nekuvandudza zvakanyanya kushandiswazve kwemvura kushandiswa kana kutevedzera.
Ozone chikumbiro mashandiro:
Ozone yakasimba yakasimba, uye redox yayo mvura iri yechipiri chete kune fluorine. Inowanzo shandiswa mukumberi uye kurapwa kwepamberi kwemvura yekushandisa indasitiri. Iine mabasa mazhinji mukurapa mvura, kutapudza, decolorization, deodorization, deodorization uye kuora kweiyo oxidative. Ozone inonyanya kushandiswa kuburitsa uye kudzikisira zvinhu zvakasikwa uye kudzikisa tsika dzeCOD neBOD mukurapa kwekudhinda uye kudhaya mvura yakasviba.
Mukubata ne chromaticity yekudhinda uye yekudhaya mvura yakasviba, ozone oxidation inogona kutyora chisungo chakavezwa cheye dhayi-ichipa kana chromogenic geni redhayi, uye panguva imwe chete ichiparadza iyo cyclic komputa inoumba iyo chromophore boka, nokudaro ichideredza mvura yakasviba.
Ozone inopindirana neyakaomesesa-kudzikisira organic zvinhu, izvo zvinoshandura huturu hwezvinhu zvinosvibisa uye hunyanzvi hwehunhu. Panguva imwecheteyo, dzikisa COD neBOD, uwedzere kuvandudza mhando yemvura. Ozone inogona kusanganisa zvinhu zvakawanda zvehupenyu uye ma microorganism mumvura yakasviba, uye inoderedza hunhu hwayo hweCOD neBOD pasina kusvibiswa kwechipiri uye kuora kuri nyore. Panguva imwecheteyo, inogona zvakare kudzikisira, sterilize uye deodorize. Yakave ichishandiswa zvakanyanya mukurapa kwepamberi kwekushambidzwa kwemvura yakasviba.
