Iko kukanganisa kwemakemikari akawandisa okisijeni kudiwa (COD) mumvura pahutano hwevanhu uye nharaunda yezvakatipoteredza yakakosha. COD inoshanda sechiratidzo chakakosha chekuyera kuwanda kwezvinosvibisa zvipenyu mumasisitimu emvura. Yakakwira COD mazinga anoratidza kusvibiswa kwakanyanya kweorganic, izvo zvinounza njodzi huru kune ese ecosystem uye hutano hweveruzhinji.

Toxic organic compounds inopinda mumiviri yemvura inogona kukuvadza zvipenyu zvemumvura, kusanganisira hove, uye inogona kuungana kuburikidza necheni yechikafu, ichizopedzisira yapinda mumuviri wemunhu uye ichitungamira muchetura usingaperi. Semuenzaniso, kuratidzwa kwenguva refu kuzvinhu zvakaita seDDT kwave kwakabatana nemhedzisiro yakaipa pahurongwa hwetsinga, kukuvara kwechiropa, kusashanda zvakanaka kwemuviri, uye kukanganisa kunogona kuitika kune kubereka uye genetic masisitimu, kusanganisira kuwedzera njodzi dzekuzvarwa abnormalities uye carcinogenesis.

High COD mazinga zvakare anokanganisa kunaka kwemvura uye kukanganisa chiyero che ecological. Kana zvinosvibisa zvipenyu zvinopinda munzizi nemadziva pasina kurapwa nenguva, mazhinji anoiswa pasi pasi. Nekufamba kwenguva, zvinhu izvi zvakaunganidzwa zvinounza chepfu yenguva refu pahupenyu hwemumvura. Izvi zvinoratidzira nenzira mbiri dzinokosha: kutanga, kufa kwakawanda kwezvipenyu zvemumvura kunogona kuitika, kukanganisa gadziriro yezvipenyu uye zvingangotungamirira kukuparara kwenzvimbo dzose dzinogara mumvura; chechipiri, chepfu inoungana zvishoma nezvishoma muzvinhu zvipenyu zvakadai sehove nehove. Kushandiswa kwevanhu kwechikafu chemugungwa chakasvibiswa kunoguma nekutakurwa uye kuunganidzwa kwezvinhu izvi zvinokuvadza mukati memuviri, zvichiunza njodzi dzakakomba dzehutano hwenguva refu, kusanganisira gomarara, kusakura zvakanaka, uye kuchinja kwemajini.

Zvakare, yakawandisa yakakwira COD mazinga anokanganisa kugona kwechisikigo kuzvichenura kwemitumbi yemvura. Kushatiswa kweiyo organic matter kunodya yakanyungudika okisijeni (DO), uye kana okisijeni inoshandiswa ikadarika reoxygenation rates, DO mazinga anogona kudonha kusvika zero, zvichikonzera anaerobic mamiriro. Mumamiriro ezvinhu akadaro, anaerobic microbial activity inoenderera mberi, ichibudisa hydrogen sulfide gasi uye zvichiita kuti mvura isvibe uye ibudise kunhuwa kwakashata-zvinowanzoratidza kusvibiswa kwakanyanya.

Kushandiswa kweCOD analyzers kunoita basa rakakosha mukutarisa nekudzivirira yakawandisa COD mazinga. Iyo Boqu'COD analyzer inoshandiswa zvakanyanya mukuongororwa kwemvura yepamusoro, mvura yepasi, tsvina yemumba, uye tsvina yemumaindasitiri. Iyo inotsigira zvese nekukurumidza pa-saiti yekuyedzwa kwekukurumidzira uye chaiyo marabhoritari-yakavakirwa mvura yemhando yekuongorora, ichiiita chishandiso chinogoneka chekutarisa kwezvakatipoteredza uye kudzora kusvibiswa.
