Mushonga weAerobic Bacteria
Tsananguro
Ihupfu chena uye inoumbwa nemabhakitiriya necocci, izvo zvinogona kuumba spores (endospores).
Ine huwandu hwebhakitiriya mhenyu hunopfuura 10-20bn/gram
Munda weKunyorera
Yakakodzera nzvimbo ine okisijeni yakawanda munzvimbo dzemafekitori ekurapa mvura yakasviba emaguta, marudzi ese emvura yakasviba yemakemikari muindasitiri, kudhinda nekudhaya mvura yakasviba, leachate yemarara, mvura yakasviba muindasitiri yechikafu uye mamwe marara eindasitiri.
Mabasa Makuru
1. Mabhakitiriya ane basa rakanaka rekuparadza zvinhu zvipenyu mumvura. Nekuda kwemabhakitiriya ane simba guru rekudzivirira zvinhu zvinokuvadza zvekunze. Anogona kuita kuti sisitimu yekuchenesa tsvina ive nesimba guru rekudzivirira kukanganiswa, uye ine simba guru rekubata tsvina, sisitimu iyi inogona kushanda zvakanaka kana huwandu hwetsvina huchichinja zvakanyanya, zvichiita kuti mvura ibude zvakanaka.
2. Mabhakitiriya anoputika anogona kubvisa BOD, COD neTTS zvinobudirira. Wedzera kugona kwekugara kwakasimba mu sedimentation basin zvakanyanya, kuwedzera huwandu nekusiyana kweprotozoa.
3. Sisitimu yekutanga nekudzoreredza zvinhu nekukurumidza, wedzera kugona kwayo kugadzirisa zvinhu uye kugona kwayo kudzivirira kukanganiswa kwezvinhu, deredza huwandu hwetsvina inogadzirwa zvinobudirira, deredza kushandiswa kwemakemikari akadai seflocculant, chengetedza magetsi.
Nzira Yekushandisa
1. Zvichienderana nenhamba yemhando yemvura muhurongwa hwemakemikari emvura yakasviba yemaindasitiri: chiyero chekutanga chingangoita 80-150 magiramu/cubic (zvichienderana nekuverenga kwehuwandu hwedziva remakemikari).
2. Kana ikakanganisa zvakanyanya mashandiro emuviri nekuda kwekuchinja-chinja kwemvura, wedzera imwe 30-50 gramu/cubic pazuva (zvichienderana nekuverenga kwehuwandu hwemvura inoyerera mudziva).
3. Chiyero chemvura yakasviba yemuguta i50-80 magiramu/cubic (zvichienderana nekuverengwa kwehuwandu hwedziva rebiochemical).
Tsanangudzo
Bvunzo iyi inoratidza kuti zvinotevera zvinoumba kukura kwebhakitiriya zvinonyatsoshanda:
1. pH: Pahuwandu hwe5.5 ne9.5, kukura kukuru kuri pakati pe6.6-7.8, tsika iyi yakaratidza kushanda zvakanaka muPH 7.5.
2. Tembiricha: Ichatanga kushanda pakati pe8℃-60℃. Mabhakitiriya achafa kana tembiricha yakakwira kupfuura 60℃. Kana iri pasi pe8℃, haizofi, asi kukura kwebhakitiriya kuchadzikira zvakanyanya. Tembiricha yakakodzera iri pakati pe26-32℃.
3. Okisijeni Yakanyungudutswa: Okisijeni yakanyungudutswa inosvika 2 mg/l mutangi remvura yakasviba; kugaya chikafu uye kukurumidza kwehutachiona hwehutachiona hunogona kusimba zvakanyanya kusvika kune chinhu chinotsvagwa kuchakurumidza ka5-7 kana paine okisijeni yakakwana.
4. Zvinhu Zvinotevedzana: Boka rebhakitiriya repachivande rinoda zvinhu zvakawanda mukukura kwaro, zvakaita sepotassium, iron, sarufa, magnesium, nezvimwewo. Kazhinji, rine zvinhu zvakakwana muvhu nemumvura.
5. Munyu: Inoshanda mumvura ine munyu nemumvura yakachena, munyu unobvumirwa zvakanyanya ne6%.
6. Kuramba Chepfu: Inogona kuramba zvine hungwaru zvinhu zvine chepfu zvine makemikari, zvinosanganisira chloride, cyanide nesimbi dzinorema, nezvimwewo.
