Tsvina inogadzirwa nechikafu yagara ichinetsa upenyu hwedu.Iyo tsvina kubva kumabhizinesi echikafu ine akasiyana inorganic uye organic zvinosvibisa, pamwe neakawanda mabhakitiriya, anosanganisira Escherichia coli, anogona pathogenic mabhakitiriya uye akasiyana mabhakitiriya, saka mhando yemvura ine madhaka uye yakasviba.Kurapa tsvina yezvokudya, tinoda midziyo yekuchenesa tsvina yezvokudya.
Zvimiro zvemidziyo yekuchenesa tsvina mufekitari yechikafu:
1. Iyo yakazara seti yemidziyo inogona kuvigwa pasi pechando chechando kana kuiswa pasi.Ivhu riri pamusoro pemidziyo rinogona kushandiswa segirini kana imwe nyika, pasina kuvaka dzimba, kudziyisa uye kupisa kwemafuta.
2. Chechipiri biological contact oxidation process inotora iyo push-flow biological contact oxidation, uye maitiro ayo ekurapwa ari nani pane aya akanyatsosanganiswa kana maviri-matanho akatevedzana akasanganiswa zvizere biological contact oxidation tank.Kana ichienzaniswa neyakagadziriswa sludge tank, ine vhoriyamu idiki, inochinjika kumhando yemvura, yakanaka kukanganisa mutoro kuramba, yakagadzikana effluent mhando uye haina sludge bulking.Iyo nyowani elastic solid solid filler inoshandiswa mutangi, iyo ine yakakura chaiyo nzvimbo uye iri nyore kuti ma microorganisms atumbe uye abvise membrane.Pasi pemamiriro akafanana emutoro wehupenyu, chiyero chekubvisa kwezvinhu zvehupenyu chakakwira, uye kunyungudika kweokisijeni mumhepo mumvura kunogona kuvandudzwa.
3. Iyo biological contact oxidation nzira inogamuchirwa yebiochemical tank.Kuremerwa kwevhoriyamu yekuzadza kwayo kwakadzikira, iyo microorganism iri mune yayo yega oxidation nhanho, uye iyo sludge kugadzirwa idiki.Zvinongotora inopfuura mwedzi mitatu (mazuva makumi mapfumbamwe) kuburitsa sludge (yakaputirwa kana kubviswa mvura mukati medhaka keke rekutakura kunze).
4. Mukuwedzera kune yakajairwa yakakwirira-yakakwirira-yakakwirira-yakakwirira, iyo deodorization nzira yezvokudya zvetsvina yemidziyo yekuchenesa inoshongedzerwawo nematanho ekubvisa ivhu.
5. Yese midziyo yekugadzirisa hurongwa inogadziriswa nemagetsi ekugadzirisa magetsi ekugadzirisa, iyo yakachengeteka uye yakavimbika mukushanda.Kazhinji, haidi vashandi vakasarudzika kuti vabate, asi inongoda chete kuchengetedza nekuchengetedza michina nenguva.
