Flocculation uye sedimentation yemvura yekurapa flocculants mukurapwa kwetsvina

Mvura Kurapa Flocculantchinhu chinowanzo shandiswa mumiririri wepretreatment mukurapwa kwetsvina!Mukuita kwekugadziriswa kwemvura yakasviba, inoda kuenda kuburikidza neakatevedzana matanho ekushanda, uye mushure mekuedzwa, inosangana neyakajairwa chiyero uye yobva yaburitswa.Saka, ibasa rei rinoitwa mvura yekuchenesa flocculant mukuchenesa mvura yetsvina?Mvura yekurapa flocculant flocculation uye sedimentation mukurapa kwemvura yakasviba;muitiro wemvura kurapwa flocculant mune tsvina kurapwa.

1. Mvura yetsvina inotanga kupfuura nepakati pegridi nechidzitiro yobva yayerera ichienda kune flocculation sedimentation tank.Kuitira kuti kurapwa kuite zvirinani, coagulant inowedzerwa kune flocculation sedimentation tangi kuti kurapwa kwezvakarembera zvakaomeswa mumvura yetsvina zviri nani, uye coagulation uye dosing inoitawo basa.Basa rekugadzirisa mvura yetsvina.Mvura yetsvina mushure mekufamba uye sedimentation inoyerera ichipinda mu pre-aeration inodzora tangi.

2. Mhepo inounzwa mutangi rekugadzirisa aeration kuti uite basa rekugadzirisa pre-aeration.Mvura yetsvina yakagadziridzwa zvakafanana inosimudzwa kune yekutanga-level inoyangarara yakarongedza biochemical tank nepombi.

3. Musoro weaeration une high oxygenation inobudirira inoiswa mudziva rebiochemical, uye kutakura kunoyerera kunoiswa.Mvura yetsvina iri muchikamu chekutanga chinoyangarara ichirongedza biochemical dziva inoyerera ichipinda muchikamu chechipiri chinoyangarara ichirongedza biochemical dziva.Dziva rechipiri rinotora nzira imwechete.

4. Mvura inobva mubhayochemical tank yechipiri inoyangarara packing inoyerera ichipinda mu inclined plate sedimentation tank.Iyo polypropylene honeycomb inclined chubhu inowedzerwa kune tangi, iyo inogona kuvandudza zvakanyanya kugadzirisa kugadzirisa.Mukuwedzera, iyo hydraulic load yakakwirira, nguva yekugara ipfupi, uye nzvimbo yepasi iduku.

5. Iyo sedimentation sludge mu coagulation sedimentation tank uye inclined plate sedimentation tank inobudiswa mumatope ekukora tangi, uye inobva yapedzwa nemvura nemuchina wekubvisa mvura.

6. Mvura inobudiswa kubva kune inclined plate sedimentation tank inoyerera ichipinda mutangi remvura yakachena, uye inobudiswa mushure mekuedzwa.

Izvo zviri pamusoro ndiyo nzira yekushandiswa kwemaflocculants mumvura yetsvina.Flocculantsinogona kunyatso bvisa diki mamorekuru akaturikwa nyaya mumvura, kuitira kuti mvura isangane nemiyero yekubuda uye inogona kuburitswa kana kudzokororwa zvakajairika.
