Mvura yakasviba kubva mukurima uye kugadzira chikafuine hunhu hwakakosha hunoisiyanisa kubva kune yakajairika mvura yetsvina yemunisiparati inochengetedzwa neveruzhinji kana yakavanzika zviteshi zvekuchenesa mvura pasi rose: inoora uye haina chepfu, asi ine yakakwira biological oxygen kudiwa (BOD) uye yakamiswa solids (SS).Kuumbwa kwechikafu uye yekurima tsvina yekurima kunowanzo kuoma kufanotaura nekuda kwekusiyana kweBOD uye pH mazinga mumvura yakaraswa kubva mumiriwo, michero uye nyama zvigadzirwa, pamwe chete nenzira dzekugadzira chikafu uye mwaka.
Zvinotora mvura yakawanda yakanaka kugadzira chikafu kubva kune zvigadzirwa.Kusuka miriwo kunoburitsa mvura ine zvidimbu zvakawanda uye zvimwe zvakanyungudika.Inogonawo kunge iine surfactants uye mishonga yezvipembenene.
Zvivakwa zveAquaculture (mapurazi ehove) anowanzo kubudisa yakawanda yenitrogen uye phosphorus, pamwe chete nemarara akamiswa.Zvimwe zvivako zvinoshandisa zvinodhaka uye mishonga yezvipembenene inogona kunge iripo mumvura yakasviba.
Zvigadzirwa zvemukaka zvinogadzira zvinosvibisa zvakajairwa (BOD, SS).
Kuurayiwa kwemhuka uye kugadzirwa kunogadzira tsvina kubva mumvura yemuviri, seropa uye zviri mukati memukati.Zvinosvibisa zvinogadzirwa zvinosanganisira BOD, SS, coliform, oiri, organic nitrogen, uye ammonia.
Chikafu chakagadzirwa chiri kutengeswa chinogadzira tsvina kubva mukubika, iyo inowanzo pfuma muzvirimwa-organic zvinhu uye inogonawo kunge iine munyu, zvinonhuwidza, zvinhu zvemavara uye asidhi kana mabhesi.Panogonawo kunge paine huwandu hukuru hwemafuta, mafuta uye magirisi (" FOG ") iyo muhuwandu hwakakwana inogona kuvhara madhiri.Mamwe maguta anoda maresitorendi uye magadzirirwo echikafu kuti ashandise girizi blockers uye kudzora mabatirwo eFOG mumasuweji.
Zviitiko zvekugadzira chikafu zvakaita sekuchenesa zvirimwa, kubata zvinhu, kuisa mabhodhoro uye kucheneswa kwechigadzirwa zvinoburitsa tsvina.Nzvimbo zhinji dzekugadziridza chikafu dzinoda kurapwa panzvimbo isati yashanda mvura yetsvina inogona kushandiswa panyika kana kuiswa munzira yemvura kana seweji.Yakakwira yakamiswa solids mazinga e organic particles anogona kuwedzera BOD uye anogona kukonzera yakakwira seweji yekuwedzera.Sedimentation, wedge-shaped screens, kana rotating strip filtration (microsieving) inzira dzinowanzoshandiswa kuderedza mutoro wezvakarembera organic solids isati yaburitswa.Cationic yakakwirira-inoshanda mafuta-mvura separator zvakare inowanzoshandiswa mukudya chirimwa chine mafuta sewage treatment (yakakwirira-inoshanda mafuta-mvura separator yeine anionic makemikari kana zvisina kunaka zvidimbu zvimedu zvetsvina kana tsvina, ingave ichishandiswa yega kana neinorganic coagulant kushandiswa kwekomboni, inogona. kuwana nekukurumidza, kunoshanda kupatsanura kana kucheneswa kwezvinangwa zvemvura.Kunyanya kushanda kwemafuta uye mvura yekuparadzanisa ine synergistic mhedzisiro, inogona kukurumidza kuyerera kumhanya, kuderedza mutengo wekushandisa zvigadzirwa).
