Kurapa Mvura Yetsvina

Kuongorora Mvura Yetsvina & Mvura Yetsvina
Kurapa tsvina inzira inobvisa tsvina yakawanda kubva mumvura yakasviba kana tsvina uye inoburitsa tsvina yemvura yakakodzera kuraswa kunzvimbo yakasikwa uye tsvina. Kuti ishande, tsvina inofanira kutakurwa kuenda kunzvimbo yekurapa nepaipi dzakakodzera uye nzira yacho pachayo inofanira kudzorwa. Dzimwe mvura yakasviba dzinoda nzira dzakasiyana uye dzimwe nguva dzakagadzirwa. Padanho riri nyore, kurapwa kwetsvina uye mvura zhinji yakasviba kunoitwa nekuparadzaniswa kwezvinhu zvakasimba kubva mumvura, kazhinji nekugadziriswa. Nekushandura zvinhu zvakanyungudutswa kuita zvinhu zvakasimba, kazhinji boka rezvisikwa uye kugadzirisa izvi, mvura yakasviba inowedzera kuchena.
Tsananguro
Tsvina tsvina inobva muzvimbuzi, mabhavhu, mashawa, makicheni, nezvimwewo inoraswa kuburikidza nemasewer. Munzvimbo dzakawanda tsvina inosanganisirawo mamwe marara anobva muindasitiri nekutengeserana. Munyika dzakawanda, tsvina inobva muzvimbuzi inonzi tsvina yakasviba, tsvina inobva muzvinhu zvakaita semabheseni, mabhavhu nemakicheni inonzi mvura ye sullage, uye tsvina yeindasitiri neyekutengeserana inonzi tsvina yekutengeserana. Kupatsanurwa kwemvura yemumba inoyerera mumvura ye grey nemvura nhema kuri kuwedzera munyika dzakabudirira, nemvura ye grey ichibvumirwa kushandiswa kudiridza zvirimwa kana kudzokororwa kushandiswa pakuchenesa zvimbuzi. Tsvina yakawanda inosanganisirawo mamwe mvura pamusoro pedenga kana munzvimbo dzakaoma. Saka mvura yemuguta inosanganisira tsvina yemvura yemudzimba, yekutengeserana, uye yemumaindasitiri, uye inogona kusanganisira mvura inoyerera kubva mumvura yedutu.

Maparamita Anowanzoedzwa:

• BOD (Kudiwa kweOxygen yeBiochemical)

•COD (Kudiwa kweOkisijeni yeMakemikari)

•MLSS (Mixed Liquor Suspended Solids)

•Oiri neGirisi

•pH

•Kufambisa kwemhepo

•Zvinhu Zvizere Zvakanyungudutswa

BOD (Kudiwa kweOkisijeni yeBiochemical):
Kudiwa kweokisijeni yemakemikari kana kuti BOD huwandu hweokisijeni yakanyungudutswa inodiwa nezvisikwa zvipenyu zve aerobic mumuviri wemvura kuti iparadze zvinhu zvipenyu zviri mumvura yakapihwa sample pane imwe tembiricha kwenguva yakatarwa. Izwi iri rinorevawo maitiro emakemikari ekuona huwandu uhu. Uku hakusi kuyedzwa kwakanyatsojeka kwehuwandu, kunyangwe kuchishandiswa zvakanyanya sechiratidzo chemhando yemvura yeorganic. BOD inogona kushandiswa sechiyero chekushanda kwenzvimbo dzekurapa mvura yakasviba. Yakanyorwa senzvimbo inosvibisa mvura yakajairika munyika zhinji.
COD (Kudiwa kweOkisijeni yeKemikari):
Mumakemikari ezvakatipoteredza, bvunzo yekudiwa kweokisijeni yemakemikari (COD) inowanzo shandiswa kuyera huwandu hwemakemikari emumvura asina kunanga. Kushandiswa kwakawanda kweCOD kunotarisa huwandu hwezvinosvibisa zvemumvura zvinowanikwa mumvura yepamusoro (semuenzaniso mumakungwa nenzizi) kana mumvura yakasviba, zvichiita kuti COD ive chiyero chinobatsira chemhando yemvura. Hurumende zhinji dzinoisa mitemo yakasimba maererano nekudiwa kwakanyanya kweokisijeni yemakemikari inobvumirwa mumvura yakasviba isati yadzorerwa kunharaunda.
