Munguva yekugadzirisa marumaru nezvimwe zvinhu zvematombo, mvura yakasviba inogadzirwa ine huwandu hwakawanda hweupfu hwematombo uye chinotonhodza. Kana mvura iyi yakasviba ikaburitswa zvakananga, haingokonzere chete kutambisa mvura, asiwo inosvibisa nharaunda zvakanyanya. Kuti igadzirise dambudziko iri, kambani imwe inoshandisa nzira yekuchenesa matombo, yakasanganiswa nepolyaluminum chloride (PAC) nepolyacrylamide (PAM), yakasanganiswa nemichina yekudzvanya firita, kuti pave nekugadzirisa uye kudzokorodza tsvina yetsvina zvinobudirira, ukuwo zvichigadzira mamwe mabhenefiti ehupfumi.
1. Hunhu nematambudziko ekurapwa kwetsvina yetsvina
Mvura yakasviba inogadzirwa nemarble ine hunhu hwekuwanda kwezvimedu zvakasungirirwa uye musanganiswa wakaoma. Zvidimbu zvitete zveupfu hwematombo zvakaoma kugara zvakasikwa, uye chinotonhodza chine makemikari akasiyana-siyana akadai semasurfactants, zvinodzivisa ngura, nezvimwewo, izvo zvinowedzera kuoma kwekurapa mvura yakasviba. Kana zvikasagadziriswa zvakanaka, zvinhu zvakasungirirwa mutsvina zvichavhara mapaipi, uye makemikari ari muchinhu chinotonhodza achasvibisa ivhu nemvura.
2, Filter press processing flow
Kambani iyi yakaisa michina yekusefa inoshanda zvakanyanya musystem yekuchenesa tsvina. Chekutanga, wedzera polyaluminum chloride nepolyacrylamide mumabhaketi ekuyedza ane filter press, wozvinyungudutsa wozvisanganisa nechikamu chakati. Mushonga wakanyungudutswa unodzorwa nemazvo nepombi yekuyedza kuti uunze kutangi rekusanganisa refilter press. Mutangi rekusanganisa, makemikari anosanganiswa zvakakwana netsvina, uye macoagulation uye flocculation reactions zvinoitika nekukurumidza. Zvadaro, mvura yakasanganiswa inopinda mukamuri rekusefa refilter press, uye pasi pekumanikidzwa, mvura inoburitswa nejira rekusefa, ukuwo sediment ichivharirwa mukamuri rekusefa. Mushure menguva yekusefa kwepressure, keke rematope rine hunyoro hushoma rinoumbwa, zvichiita kuti pave nekupatsanurwa kwakanaka kwechinhu chakasimba nechinwiwa.
Muchidimbu, kushandiswa kwenzira yekuchenesa makemikari, pamwe chete nepolyaluminum chloride nepolyacrylamide, uye pamwe chete nemidziyo yekusvina filter press kurapa mvura yakasviba inogadziriswa nemarble inzira inoshanda, isingadhuri, uye isingakuvadzi nharaunda ine kukosha kwakanaka kwekusimudzirwa.
3, Kusarudzwa kwemuenzaniso wekudhinda firita
