Sisitimu yakakwana yekuchenesa tsvina yemutaundi inofanira kunge yakavakirwa pahuwandu hwevanhu vemunharaunda, nzvimbo, mamiriro ehupfumi nezvimwe zvinhu kuti zviongororwe zvizere, kusarudza michina yakakodzera yekuchenesa tsvina uye kuenderana kwayo.
Grid ndiyo nzira yekutanga muhurongwa hwekuchenesa tsvina, inoshandiswa kubata zvinhu zvikuru zvakasimba. Kuisa grid kunogona kukamurwa kuita coarse grating uye fine grating, coarse grating inonyanya kushandiswa kubata zvinhu zvikuru zvakasungirirwa, zvakaita semashizha, mabhegi epurasitiki, nezvimwewo; fine grating inonyanya kushandiswa kubata zvinhu zvidiki zvakasungirirwa, zvakaita sedongo, marara, nezvimwewo.
Tangi rejecha rinoshandiswa kubvisa jecha nezvimedu zvisina kugadzirwa zvine simba guru rekukura mumvura yetsvina. Tangi rejecha rinowanzoiswa mune imwe saizi yetangi rekukura, mvura inoyerera kuburikidza nekushandisa simba regiravhiti kuti zvimedu zvidzike pasi.
Tangi rekutanga remvura inodonha pasi chikamu chakakosha chehurongwa hwekuchenesa tsvina, chinoshandiswa kubvisa zvinhu zvakasungirirwa pamwe nezvimwe zvinhu zvipenyu zviri mutsvina. Tangi rekutanga remvura inodonha pasi rinoisa zvinhu zvakasungirirwa pasi nekushandisa sedimentation yechisikigo kana scraper scraping, uye rinozozviburitsa kuburikidza nemidziyo yekuburitsa tsvina.
Tangi rekugadzirisa zvinhu zvipenyu ndiro chinhu chikuru chekugadzirisa mvura yakasviba uye rinoshandiswa kuparadza zvinhu zvipenyu nekubvisa tsvina dzakadai seammonia, nitrogen nephosphorus. Zvipembenene zvakasiyana-siyana, kusanganisira zvipembenene zvine aerobic uye zvipembenene zvisina aerobic, zvinowanzo kurimwa mu bioreactor, uye zvinhu zvipenyu zvinoshandurwa kuita zvinhu zvisina njodzi kuburikidza nekushandiswa kwezvipembenene.
Tangi rechipiri re sedimentation ndiro tangi re sedimentation rinoteverwa ne bioreactor, iro rinoshandiswa kuparadzanisa sludge yakabatidzwa mu bioreactor kubva mumvura yakacheneswa. Tangi rechipiri re sedimentation rinoshandiswa kukwesha sludge yakabatidzwa kuenda kunzvimbo yepakati yekuunganidzira sludge uchishandisa scraper kana muchina wekukweva, uye sludge yakabatidzwa inodzoserwa ku bioreactor uchishandisa muchina wekudzosera sludge. Midziyo yekuuraya utachiona inoshandiswa kuuraya tupukanana twakadai semabhakitiriya nemavhairasi ari mutsvina, uye nzira dzinowanzoshandiswa dzekuuraya utachiona ndedze chlorination disinfection uye ozone disinfection.
Pamusoro pemichina yekuchenesa tsvina yataurwa pamusoro apa, kune mimwe michina yekubatsira, yakaita semabhurower, mamixer, mapombi nezvimwewo. Midziyo iyi inoita mabasa akasiyana mukugadzirisa tsvina, zvakaita sekupa oxygen, kusanganisa tsvina, kusimudza tsvina nezvimwewo.
Pakusarudza nekufananidza michina yekuchenesa tsvina, hunhu nemamiriro chaiwo eguta zvinofanira kutariswa. Semuenzaniso, kunzvimbo dzine vanhu vashoma uye nzvimbo dzakaoma, michina midiki uye yemhando dzakasiyana yekuchenesa tsvina inogona kusarudzwa kuti iite kuti zvifambiswe uye zviiswe nyore; kunzvimbo dzine mamiriro ehupfumi ari nani, michina ine tekinoroji yepamusoro uye inoshanda zvakanyanya pakurapa inogona kusarudzwa. Panguva imwe chete, zvinhu zvakaita sekugadzirisa nekushandisa michina, pamwe nekureruka kwekushanda kwayo uye kuvimbika kwayo, zvinofanirwa kutariswa.
Kambani yeLiding Environmental Protection inonyanya kugadzira nekugadzira michina yekuchenesa tsvina yemumaguta, pamwe nekushanda chaiko kwepurojekiti, uye ine ruzivo rwakakura muindasitiri, umo michina yekuchenesa tsvina yakabatana ine hutungamiriri hwakati muindasitiri.
