Sisitimu yakakwana yekuchenesa tsvina yemutaundi inofanira kufungwa zvizere zvichienderana nehuwandu hwevanhu vemunharaunda, mamiriro evhu, mamiriro ehupfumi nezvimwe zvinhu, uye kusarudza michina yakakodzera yekuchenesa tsvina uye nzvimbo yakakodzera yekubatanidza. Grille ndiyo nhanho yekutanga musisitimu yekuchenesa tsvina, iyo inoshandiswa kuvharira zvinhu zvikuru zvakasimba. Grating inogona kukamurwa kuita coarse grille uye fine grille, coarse grille inonyanya kushandiswa kuvharira zvinhu zvakakura zvakasungirirwa, zvakaita semashizha, mabhegi epurasitiki; fine grille inonyanya kushandiswa kuvharira zvinhu zvidiki zvakasungirirwa, zvakaita sesediment, marara, nezvimwewo. Jecha rinogadzika rinoshandiswa kubvisa zvidimbu zvejecha nezvimedu zvisingasanganisike zvine huwandu hwakawanda musediment. Kazhinji, chiyero chakati chesedimentation tank chinoiswa musedimentation tank, uye simba rekuyerera kwesediment. Primary sedimentation tank chikamu chakakosha chesisitimu yekuchenesa tsvina, iyo inoshandiswa kubvisa sleeded matter nezvimwe zvinhu zvipenyu musediment.
Tangi rekutanga re sedimentation rinogadzika pasi pechinhu chakarembera kuburikidza nekunaya kwemvura kana kukwenya mud scraper, uye rozopfuura nemumidziyo inoburitsa mud. Tangi re biological reaction ndiro chikamu chikuru chesystem yekuchenesa tsvina, iyo inoshandiswa kusvibisa zvinhu zvipenyu nekubvisa tsvina dzakadai seammonia nitrogen nephosphorus. Zvipembenene zvakasiyana-siyana zvinowanzo kurimwa mudziva re biological reaction, kusanganisira aerobic microorganisms uye anaerobic microorganisms, izvo zvinogona kushandura organic matter kuita zvinhu zvisina njodzi kuburikidza ne metabolism ye microorganisms. Tangi rechipiri re sedimentation itangi re sedimentation mushure me biological reaction tank, iyo inoshandiswa kuparadzanisa activated sludge mu biological reaction tank kubva mumvura yakagadziriswa. Tangi rechipiri re sedimentation rinokwenya activated sludge kuenda kunzvimbo yepakati inounganidza sludge kuburikidza nemuchina we sludge scraper kana mud suction, uye ipapo activated sludge inodzoserwa ku biological reaction tank kuburikidza nemuchina we sludge reflux. Midziyo ye disinfection inoshandiswa kuuraya mabhakitiriya nemavhairasi nezvimwe zvipembenene zviri mutsvina. Nzira dzinoshandiswa zvakanyanya dze disinfection dzinosanganisira chlorination disinfection uye ozone disinfection.
Pamusoro pemichina yekuchenesa tsvina yataurwa pamusoro apa, kune mimwe michina yekubatsira, yakaita semuchina wekufembedza, musanganiswa, pombi yemvura nezvimwewo. Midziyo iyi ine mabasa akasiyana mukugadzirisa tsvina, akadai sekupa okisijeni, kusanganisa tsvina, kusimudza tsvina, nezvimwewo.
Pakusarudza nekufananidza michina yekuchenesa tsvina, tinofanira kufunga nezvehunhu hweguta uye mamiriro chaiwo eguta. Semuenzaniso, kunzvimbo dzine vanhu vashoma uye nzvimbo dzakaoma, michina midiki uye yekuchenesa tsvina inogona kusarudzwa kuti ive nyore kutakurwa nekuiswa; kunzvimbo dzine mamiriro ehupfumi ari nani, michina ine tekinoroji yepamusoro uye inoshanda zvakanyanya pakurapa inogona kusarudzwa. Panguva imwe chete, mari yekuchengetedza nekushandisa michina, pamwe nekureruka nekuvimbika kwekushanda kwayo, zvinofanirwa kufungwa nezvazvo.
