Mvura yese yekunwa ichabatwa kubva kune mvura sosi, rwizi, mvura tsime, kana dzimwe nguva mvura yemvura inogona kuve isina njodzi kana mamiriro ekunze ane hukama kana shanduko yemwaka. Kuongorora mamiriro emvura emvura ipapo inokuita kuti ufungisise shanduko pakurapa maitiro.
Chekutanga Nhanho: Pre-kurapa kweinobva mvura, zvakare inonzi secalation uye kuwanda, zvimedu zvichabatanidzwa nemakemikari kuti aumbe zvigunwe zvakakura, ipapo zvikamu zvakakura zvichanyura kuzasi kuzasi.
Nhanho yechipiri ndeyekupedzisira, mushure mekurapa mukurapa, mvura yakajeka ichapfuura napakati pemafirita, kazhinji, iyo firita inoumbwa nejecha, gravel, uye charavel, uye size size. Kuti udzivirire mafirita, isu tinofanirwa kuongorora turbidity, takamiswa solid, alkalinity uye imwe yemhando yemhando yemvura.
Yetatu nhanho ndeye disination maitiro. Nhanho iyi yakakosha kwazvo, mushure memvura yakasviba, isu tinofanirwa kuwedzera mvura yemvura, sekurayira, kurongeka, mabhakitiriya, uye vavairasi, vanoona kuti mvura yakachengeteka kana ikaputirwa pamba.
Nhanho yechina kugoverwa, isu tinofanirwa kuyera ph, turbidity, kuomarara, kusara chlorine, kubatana (TDS), saka tinogona kuziva njodzi dzinogona kuitika kana kutyisidzira kune uzhinji revanhu nenguva. Iyo yakasara chlorine kukosha inofanirwa kunge iri pamusoro 0.3mg / l kana ichinge yadonhedzwa kubva pakunwa mvura yemvura, uye anopfuura 0.05mg / l pakupera kwePIPE network. Turbidity inofanirwa kushoma 1NTU, PH kukosha ndeye 6.5 ~ 8,5, pombi ichaita kana ph kukosha ishoma 6.5ph uye nyore uye phr iri pamusoro pe8,5ph.
Nekudaro parizvino, basa remhando yemhando yekutarisa inonyanya kutora bhuku renyama munyika dzakawanda, dzinotyisa uye kukanganisa kwevanhu Inopawo ruzivo rwekukurumidza uye rwakanaka kune sarudzo-madzishe anoenderana nekuchinja kwemvura munguva chaiyo. Nokudaro vachipa vanhu vane hutano hwakanaka uye hwakachengeteka hwemvura mhando.
