Sewage mvura kurapwa

Sewage mvura & effluent yemvura kuongorora
Kurapa kweSewage ndiyo inobvisa huwandu hwevanhu vanosvibisa kubva pakusvibisa kubva pakutsamwa kubva kumarara-emvura kana kugadzirwa uye kubereka zvese zvinwiwa zvinokwana zvakaringana kune zvakasikwa nharaunda uye sludge. Kuti ubudirire, seage inofanirwa kuendeswa kune chirimwa chekurapa nemapepa akakodzera uye mashandiro ega uye maitiro ayo anofanirwa kuve pasi pemutemo uye kutonga. Mamwe marara emarara anoda kazhinji kazhinji akasiyana uye dzimwe nguva nzira dzekurwisa dzekurwisa dzekurwisa. Pakurapa kwakareruka kwekurapa kwegungwa uye yakawanda marara emvura kuburikidza nekuparadzaniswa kweiyo solids kubva kune zvinwiwa, kazhinji nekugadzirisa. Nekushandurwa zvishoma nezvishoma zvinhu zvakanyungudika, kazhinji boka rekubereka uye kugadza izvi, rwizi rwevhu rekuwedzera kwekuwedzera kunogadzirwa.
Tsanangudzo
Sewage ndiyo tsvina yemvura kubva kuzvimbuzi, mabhati, mafashama, makiromita, nezvimwewo zvinoratidzwa nezvikwangwani. Munzvimbo dzakawanda dzeSewage Inosanganisirawo mamwe marara kubva muindasitiri uye kutengeserana. Munyika dzakawanda, marara kubva kuchimbuzi anotsauswa marara, marara kubva pamidziyo, mabhati uye mabhati anoteedzerwa mvura, uye marara efoni uye anotengeserana anonzi anotambidza tsvina. Chikamu chemvura inodonha nemvura yegrey nemvura yegrey uye mvura dema zviri kuwedzera munyika yakashambadzirwa, nemvura yegrey ichitenderwa kuti ishandiswe zvidyarwa kana kudzoserwa zvimbuzi. Sewage yakawanda inosanganisirawo imwe mvura yemvura kubva kumatenga kana nzvimbo dzakaoma-dzakamira. Mvura yemaronda emvura saka inosanganisira kugara, yekutengeserana, uye maindasitiri emarara emarara anodzima, uye anogona kusanganisira dutu remvura rinomhanya.

Paramita inowanzoedzwa:

• BOD (Biochemical Oxygen inodikanwa)

•Cod (chemakemikari okisijeni)

•MLSS (yakasanganiswa doro rakamiswa solids)

•Mafuta uye mafuta

•pH

•Kuita

•Yakazara yakadzika mishonga

BOD (Biochemical Oxygen inodikanwa):
Biochemical oxygen inodikanwa yeokisijeni inodiwa neye Aerobic Biologics zvisikwa mumvura kuputsa zvinyorwa zvemvura zviripo mune imwe tembiricha pane imwe tembiricha yenguva yakatarwa. Izwi iri rinoreva zvakare maitiro emakemikari ekusarudza iyi huwandu. Iyi haisi bvunzo chaiyo yekuyera, kunyangwe ichishandiswa zvakanyanya sechiratidzo cheiyo organic mhando yemvura. BOD inogona kushandiswa seyakajekesa yekubudirira kwerambadza kurapwa kwemvura. Yakanyorwa seyakajairika kusvibiswa munyika zhinji.
Cod (makemikari okisijeni inodiwa):
Mune yemamiriro epamisirwo emamiriro ezvinhu, iyo makemikari okisijeni inodiwa (cod) bvunzo inowanzo kushandiswa kune zvisina kukodzera kuyera huwandu hwehuwandu hwemvura mumvura. Zvizhinji zvekushandisa zveCOD sarudza huwandu hwesimbe dzakawanikwa mumvura yemukati (semuenzaniso madziva uye nzizi) kana marara emvura, kugadzira cod chiyero chinobatsira chemhando yemvura. Hurumende dzakawanda dzinomutsa mitemo yakasimba maererano neyekupedzisira kesiokisiokisiokisi cheokisijeni inobvumirwa mumvura marara vasati vadzoserwa kunzvimbo.
