Sewage treatment

Kuongorora kweSewage neSewageSewage treatmentndiyo nzira yekubvisa yakawanda yezvinosvibisa kubva mumvura yetsvina kana tsvina uye kugadzira mvura inoyerera inokodzera kuraswa munzvimbo yechisikigo uye madhaka. Kuti ishande, tsvina yetsvina inofanirwa kuendeswa kunzvimbo dzekurapisa nemapombi akakodzera uye zvivakwa, uye nzira yacho pachayo inofanirwa kudzorwa nekudzorwa. Dzimwe tsvina dzemvura dzinowanzoda nzira dzakasiyana uye dzimwe nguva dzehunyanzvi dzekurapa. Mumushonga wakapfava wetsvina uye yakawanda tsvina yemvura, iyo yakaoma inowanzoparadzaniswa kubva mumvura nekugadzirisa. Inoburitsa rwizi runoyerera rwekuwedzera kuchena nekushandura zvishoma nezvishoma zvinhu zvakanyungudutswa kuita solids, kazhinji biota, nekuzvigadzirisa kunze.

Rondedzera

Sewage itsvina yemuzvimbuzi, yekugezera, yekugezera, yekubikira, nezvimwewo inoraswa nemupombi. Munzvimbo dzakawanda, tsvina inosanganisirawo imwe tsvina yemvura kubva kumaindasitiri nekutengeserana. Munyika dzakawanda, tsvina inobva muzvimbuzi inonzi tsvina ine tsvina, tsvina inobva mumidziyo yakaita semabheseni, dzimba dzokugezera uye kicheni inonzi mvura ine tsvina, uye tsvina yemumaindasitiri neyekutengesa inonzi trade waste. Zvava kunyanya kuwanda munyika dzakabudirira kupatsanura mvura yemumba kuita grey neblack, mvura ine grey ichibvumidzwa kudiridza zvirimwa kana kushandiswa patsva kuti zvimbudzi zvigeze. Matsvina mazhinji anosanganisirawo imwe mvura yepasi kubva pamatenga edzimba kana munzvimbo dzakaoma. Nekudaro, mvura yetsvina yemanisipala inosanganisira yekugara, yekutengesa, uye yekubuda kwemvura yemumaindasitiri uye inogona kusanganisira kuyerera kwemvura yemadutu.

BOD (biochemical oxygen kudiwa):

Biochemical Oxygen Demand, kana BOD, huwandu hweokisijeni yakanyungudika inodiwa neaerobic organisms mumvura yemvura kuti iparadze iyo organic matter iripo mune yakapihwa mvura sampu pane imwe tembiricha yenguva yakatarwa. Izwi iri rinorevawo maitiro emakemikari anoshandiswa kuona huwandu. Iyi haisi iyo chaiyo yehuwandu bvunzo, kunyangwe ichishandiswa zvakanyanya sechiratidzo cheiyo organic mhando yemvura. BOD inogona kushandiswa sechiratidzo chekuyera kushanda kwemiti yekuchenesa mvura. Yakanyorwa sechinhu chinowanzosvibisa munyika dzakawanda.

COD (Chemical Oxygen Demand):

Mumakemikari ezvemamiriro ekunze, iyo kemikari yeokisijeni inoda (COD) bvunzo inowanzo shandiswa kuyera zvisina kunanga huwandu hwemakemikari ari mumvura. Mazhinji mashandisirwo eCOD anotarisisa huwandu hwezvinosvibisa zvinowanwa pamusoro pemvura (semadziva nenzizi) kana mvura yetsvina, zvichiita kuti COD ive chiratidzo chakakosha chemhando yemvura. Hurumende zhinji dzakaisa mirau yakasimba pane yakanyanya kudiwa kemikari oxygen inobvumidzwa mumvura yetsvina isati yadzoserwa kunharaunda.

Kambani yeduinopinda muindasitiri yekuchenesa mvura kubvira 1985 nekupa iwo makemikari uye zvigadziriso zvemarudzi ese emaindasitiri uye emasuwa ekuchenesa zvidyarwa. Isu tiri mugadziri wemishonga yekuchenesa mvura, kusanganisiraPolyethylene glycol-PEG, Thickener, Cyanuric Acid, Chitosan, Water Decoloring Agent, Poly DADMAC, Polyacrylamide, PAC, ACH, Defoamer, Bacteria Agent, DCDA, nezvimwewo.
