Mukugadzirisa mvura yakasviba, kutarisa huwandu hwezvinhu zvakasikwa, kunyanya Total Organic Carbon (TOC), kwave kwakakosha pakuchengetedza mashandiro akanaka uye anobudirira. Izvi zvinonyanya kuitika mumaindasitiri ane nzira dzakasiyana-siyana dzemarara, dzakadai sechikamu chezvekudya nezvinwiwa (F&B).
Mubvunzurudzo iyi, Jens Neubauer naChristian Kuijlaars vekuVeolia Water Technologies & Solutions vanotaura neAZoMaterials nezvekukosha kwekutarisa TOC uye kuti kufambira mberi muhunyanzvi hweTOC kuri kushandura sei maitiro ekurapa mvura yakasviba.
Sei kutarisa huwandu hwezvinhu zvakasikwa, kunyanya Total Organic Carbon (TOC), kuchikosha pakurapa mvura yakasviba?
Jens: Mumvura zhinji dzakasviba, tsvina zhinji dzinobva muzvinhu zvakasikwa, uye izvi zvinonyanya kuitika kune chikamu cheF&B. Saka, basa guru renzvimbo yekuchenesa tsvina nderekuputsa zvinhu izvi zvepanyama nekuzvibvisa mumvura yakasviba. Kuwedzerwa kwemaitiro kuri kuita kuti kurapwa kwemvura yakasviba kukurumidze uye kushande zvakanaka. Izvi zvinoda kugara uchitarisa huwandu hwemvura yakasviba kuti igadzirise kuchinja-chinja, zvichiita kuti pave nekuchenesa kwakanaka pasinei nenguva pfupi yekurapa.
Nzira dzechinyakare dzekuyera marara emumvura, sekuyerwa kwemakemikari eoxygen (COD) uye kuyedzwa kwebiochemical oxygen (BOD), dzinononoka zvikuru - dzinotora maawa kusvika kumazuva - zvichiita kuti dzisakodzere kurapwa kwemazuva ano uye nekukurumidza. COD yaidawo ma reagents ane chepfu, izvo zvisingadiwi. Zvichienzaniswa, kutarisa mutoro wemumvura uchishandisa TOC analysis kunotora maminetsi mashoma chete uye hakusanganisire ma reagents ane chepfu. Yakakodzera kuongororwa kwemaitiro uye inopawo mhedzisiro chaiyo. Kuchinja uku kuenda pakuyerwa kweTOC kunoratidzwawo mumazinga eEU azvino maererano nekudzora kuburitsa, umo kuyerwa kweTOC ndiyo nzira inosarudzwa. Commission Implementing Decision (EU) 2016/902 yakagadza mhedziso dzakanakisa dziripo (BAT) pasi peDirective 2010/75/EU yemasisitimu ekurapa/kutarisira mvura yakasviba muchikamu chemakemikari. Sarudzo dzeBAT dzinotevera dzinogona kutaurwawo pamusoro penyaya iyi.
Basa rei rinoitwa nekutarisa TOC mukuchengetedza kushanda zvakanaka uye kushanda zvakanaka kwenzira dzekurapa mvura yakasviba?
Jens: Kutarisa TOC kunopa ruzivo rwakakosha pamusoro pekuiswa kwekabhoni munzvimbo dzakasiyana-siyana dzekuita izvi.
Kutarisa TOC isati yashandiswa pakurapa kwemuviri kunoita kuti ione kusagadzikana kwecarbon loading uye kuiendesa kumatangi ekuchengetedza sezvinodiwa. Izvi zvinogona kudzivirira kuremedza biology uye kuidzosera kumaitiro acho pane imwe nguva inotevera, zvichibvumira kushanda kwakachengeteka uye kwakasimba kwechirimwa. Kuyera TOC isati yasvika uye mushure medanho rekugadzika kunobvumirawo vashandi kudzora coagulant dosing nekuvandudza kuwedzera carbon kuitira kuti vasafa nenzara kana kudya mabhakitiriya akawanda ari mumatangi emhepo uye/kana panguva yeanoxic phases.
Kutarisa TOC kunopa ruzivo nezvehuwandu hwekabhoni panzvimbo inoburitswa uye kushanda zvakanaka kwekubvisa. Kutarisa TOC mushure mekunyudzwa kwemvura kunobatsira kuyera kabhoni inoburitswa munzvimbo inogarwa uye kunoratidza kuti miganhu inozadzikiswa. Uyezve, kutarisa organics kunopa ruzivo nezvehuwandu hwekabhoni kuti zvikwanisike kugadzirisa kurapwa kwechitatu kuti zvishandiswezve uye kunogona kubatsira kugadzirisa kuyera kwemakemikari, membrane pre-treatment, uye ozone neUV dosing.
