Kurapa tsvina

Kuongorora Tsvina uye TsvinaKurapa tsvinainzira yekubvisa tsvina yakawanda kubva mumvura yakasviba kana tsvina uye kugadzira tsvina yemvura yakakodzera kuraswa munzvimbo yakasikwa uye tsvina. Kuti ishande zvakanaka, tsvina inofanira kutakurwa kuenda kunzvimbo dzekuchenesa nekushandisa mapaipi akakodzera uye zvivakwa, uye maitiro acho pachawo anofanira kudzorwa nekudzorwa. Mamwe marara anowanzoda nzira dzakasiyana uye dzimwe nguva dzakagadzirwa. Mukurapa tsvina iri nyore uye kurapwa kwemvura yakasviba, tsvina inowanzoparadzaniswa nemvura nekugadzika. Inogadzira rukova rwemvura rwakawedzera kuchena nekushandura zvinhu zvakanyungudutswa kuita zvinhu zvakasviba, kazhinji biota, uye kuzvigadzika.

Tsanangura

Tsvina tsvina inobva muzvimbuzi, mudzimba dzekugezera, mushawa, mukicheni, nezvimwewo inoraswa nemutsvina. Munzvimbo dzakawanda, tsvina inosanganisirawo mamwe marara anobva muindasitiri nekutengeserana. Munyika dzakawanda, marara anobva muzvimbuzi anonzi tsvina, marara anobva pazvinhu zvakaita semabheseni, mudzimba dzekugezera nemakicheni anonzi mvura yetsvina, uye marara emaindasitiri neekutengeserana anonzi marara ekutengeserana. Zviri kuwanda munyika dzakabudirira kupatsanura mvura yemumba kuita mvura yegrey nenhema, nemvura yegrey ichibvumirwa kudiridza mafekitori kana kudzokororwa kuti igeze zvimbuzi. Marara mazhinji etsvina anosanganisirawo mamwe mvura pamusoro pedenga kana munzvimbo dzakaoma. Saka, mvura yetsvina yemumaguta inosanganisira mvura inobuda mudzimba, yekutengeserana, uye yemumaindasitiri uye inogona kusanganisirawo mvura inoyerera mumvura yemvura.

Maparamita ebvunzo akajairika:

·COD (Kudiwa kweOkisijeni yeMakemikari)

·MLSS (Mixed Liquid Suspended Solids)

·Kufambisa zvinhu

· Zvinhu zvose zvakanyungudutswa

BOD (kudiwa kweokisijeni ye biochemical):

Kudiwa kweOkisijeni yeBiochemical, kana kuti BOD, huwandu hweokisijeni yakanyungudutswa inodiwa nezvisikwa zve aerobic mumuviri wemvura kuti iore zvinhu zve organic zviripo mumvura yakapihwa patembiricha yakatarwa kwenguva yakatarwa. Izwi iri rinorevawo maitiro emakemikari anoshandiswa kuona huwandu. Uku hakusi kuyedza kwakanyatsojeka, kunyangwe kuchishandiswa zvakanyanya sechiratidzo chemhando yemvura ye organic. BOD inogona kushandiswa sechiratidzo chekuyera kushanda kwenzvimbo dzekuchenesa mvura yakasviba. Yakanyorwa senzvimbo inosvibisa mvura nguva dzose 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 (senge madziva nenzizi) kana mvura yakasviba, zvichiita kuti COD ive chiratidzo chinobatsira chemhando yemvura. Hurumende zhinji dzakaisa mitemo yakasimba pamusoro pekudiwa kwakanyanya kweokisijeni yemakemikari inobvumirwa mumvura yakasviba isati yadzorerwa kunharaunda.

Kambani yeduTakapinda muindasitiri yekurapa mvura kubvira muna 1985 nekupa makemikari nemhinduro dzemhando dzese dzenzvimbo dzekuchenesa tsvina dzemaindasitiri nedzemaguta. Isu tinogadzira makemikari ekurapa mvura, anosanganisiraPolyethylene glycol-PEG, Chinokora, Cyanuric Acid, Chitosan, Mumiriri weKubvisa Ruvara Mumvura, Poly DADMAC, Polyacrylamide, PAC, ACH, Defoamer, Mumiriri weMabhakitiriya, DCDA, nezvimwewo.

Kana uchifarira, ndapota taura nesukuti uwane masampuli emahara.
