Tekinoroji yekurapa mvura yeindasitiri inogona kukamurwa kuita mapoka matatu zvichienderana nezvinangwa zvekurapa uye mhando yemvura: yemuviri, makemikari, uye biological. Inoshandiswa zvakanyanya mukurapa kwemhando dzakasiyana dzemaindasitiri emarara.
1. Physical processing tekinoroji: kunyanya kusanganisira kusefa, kunaya kwemvura, kuyerera kwemhepo, uye tekinoroji yekuparadzanisa membrane. Kusefa kunowanzoshandiswa kubvisa zvimedu zvakamiswa kubva mumvura; Sedimentation uye air flotation matekiniki anoshandiswa kupatsanura oiri uye yakasimba zvimedu; Membrane separation tekinoroji, senge ultrafiltration uye reverse osmosis, anoshandiswa pakucheneswa kwepamusoro-soro uye akakodzera kurapa yakakwira munyu tsvina uye kudzoreredza zvinhu zvinobatsira.
2. Chemical treatment tekinoroji: Kubvisa zvinosvibisa kuburikidza nekuita kwemakemikari, kusanganisira nzira dzakadai seflocculation, oxidation-reduction, disinfection, uye neutralization. Flocculation uye coagulation inowanzoshandiswa kubvisa zvidimbu zvakanaka; Iyo oxidation-yekudzikisa nzira inogona kushandiswa kushatisa organic zvinosvibisa kana kubvisa zvinorema simbi; Maitiro ekuuraya hutachiona senge chlorination kana ozone kurapwa anoshandiswa zvakanyanya kushandiswa kwemvura mumaindasitiri kana kurapwa kusati kwaburitswa.
3. Biological treatment technology: kuvimba nema microorganisms kusvibisa organic matter mumvura, common technologies inosanganisira activated sludge process uye anaerobic treatment process. Iyo activated sludge process inokodzera kurapa tsvina ine yakakwira organic load, nepo anaerobic treatment tekinoroji inowanzo shandiswa kurapa yakakwira organic wastewater, iyo inogona kunyatso kusvibisa zvinosvibisa uye kudzoreredza simba (senge biogas).
Aya matekinoroji anoshandiswa zvakanyanya mukurapwa kwemvura yetsvina mumaindasitiri akadai sepetroleum, makemikari, kugadzira chikafu, uye mishonga. Ivo kwete chete zvinobudirira kuderedza kusvibiswa kwemvura, asi zvakare kuvandudza mwero wekushandiswazve kwemvura, kusimudzira kusimudzira kwakasimba kwekugadzirwa kwemaindasitiri.
