Nheyo yakakosha yekugadziriswa kwemvura mumaindasitiri ndeyekubvisa zvinosvibisa mumvura kuburikidza nemuviri, kemikari, uye nzira dzebhayoloji kuti isangane nemhando yemvura inodiwa pakugadzirwa kwemaindasitiri kana kuburitsa. Inonyanya kusanganisira matanho anotevera:

1. Pre treatment: Munguva yepreparation stage, nzira dzemuviri dzakadai sefiltration uye kunaya kwemvura dzinowanzo shandiswa kubvisa zvakaturikwa zvakasimba, tsvina ine tsvina, uye mafuta zvinhu kubva mumvura. Iyi nhanho inogona kuderedza mutoro wekutevera kugadzirisa uye kugadzirisa kugadzirisa kushanda.

2. Kurapa kwemakemikari: Nekuwedzera makemikari emakemikari akadai se coagulants, flocculants, nezvimwewo, zviduku zvakamiswa mumvura zvinosimudzirwa kuti zvigadzire flocs yakakura, iyo inobatsira kunaya kana kusefa. Pamusoro pezvo, kurapwa kwemakemikari kunosanganisirawo kubvisa organic kana chepfu kubva mumvura kuburikidza neoxidants uye zvinoderedza.

3. Biological treatment: Paunenge uchibata ne organic pollutants, Microbial degradation nzira dzakadai activated sludge uye anaerobic biological treatment inowanzoshandiswa kurapa organic pollutants. Aya ma microorganisms anoputsa zvinosvibisa kuita zvinhu zvisingakuvadzi zvakaita secarbon dioxide, mvura, uye nitrogen kuburikidza nemaitiro emagetsi.

4. Membrane separation tekinoroji: Membrane separation tekinoroji, senge reverse osmosis (RO), ultrafiltration (UF), zvichingodaro, inogona kubvisa yakanyungudutswa munyu, organic matter, uye tupukanana kubva mumvura kuburikidza nekuongororwa kwemuviri, uye inoshandiswa zvakanyanya kune yakakwirira mwero mvura. kurapwa.

Nekushandisa zvakanyanya matekinoroji ekurapa aya, kucheneswa kunoshanda uye kudzokorodza kwemvura yakaraswa kunogona kuwanikwa, kuderedza kukanganiswa kwezvakatipoteredza uye kuvandudza kushanda kwezviwanikwa zvemvura.
