Muna Zvita, 2021, iyo yakagadziriswa yakanyungudika mhepo yekufambisa yakarairwa yakapedzwa uye inosangana neyakajairwa fekitori kuti iunze zvinobudirira.
Dissolved Air Flotation (DAF System) inzira yekuchenesa mvura inojekesa mvura yetsvina (kana imwe mvura, yakaita serwizi kana dhamu) nekubvisa zvakamisikidzwa zvakasimba kana mafuta & girizi.Inoshandiswa zvakanyanya mumarara emvura kurapwa kwekuparadzaniswa kwakasimba-mvura, inogona kubvisa yakamiswa yakasimba, mafuta & girizi uye colloidal zvinhu zvinobudirira.Zvichakadaro, iyo COD, BOD inogona kuderedzwa.Ndiyo midziyo huru yekuchenesa mvura yemarara.
Mamiriro ezvinhu
DAF System inonyanya kuve neyakanyungudika yepombi yemhepo, mhepo compressor, yakanyungudika mhepo mudziyo, rectangle simbi tangi muviri, skimmer system.
1. Kushanda kuri nyore uye kutungamira kwakapusa, kudzora kwakaringana huwandu hwemvura yetsvina uye mhando.
2.The micro bubbles inogadzirwa neyakanyungudika mhepo mudziyo inongova 15-30um, iyo inonamira ine flocculant zvakasimba kuti iwane nani flotation mhedzisiro.
3. Yakasarudzika GFA yakanyungudika mhepo system, kushanda kwakanyanya kwekunyungudika kwemhepo kunogona kusvika 90%+, kugona kwakasimba kwekuvhara.
4. Chain-plate type skimmer, kushanda kwakagadzikana uye kushanda kwepamusoro kune zvimedu.
Kushanda Theory
Mvura yakanyungudutswa yemhepo inogadzirwa neGFA system inoputirwa mumhepo inoburitsa nekudzikisa kudzvanywa.15-30um mabhururu madiki kubva kumhepo inoburitsa anonamatira kune yakamiswa yakasimba inoita kuti ireruke kupfuura mvura, ipapo maonda akasanganiswa nemabhururu madiki anogona kuyangarara pamusoro kuti agadzire scum layer yaizoraswa neskimmer system mudhangi redhaka. .Mvura yakachena yepasi inoyerera ichipinda mutangi remvura yakachena.Inenge 30% yemvura yakachena inodzokororwa kuGFA system nepo imwe ichiburitswa kana kupombwa kune inotevera maitiro.
Application
DAF Sisitimu, seimwe tsvina yekuchenesa mvura maitiro, inoshandiswa zvakanyanya muinjiniya yekuchenesa tsvina.Inogona kushandiswa kune aya maindasitiri:
1. Indasitiri yemapepa - pulp recycle mumvura chena uye mvura yakachena yakadzokororwa kushandiswa.
2. Textile, kudhinda uye dhayi indasitiri - ruvara chromaticity kuderedza uye SS kubviswa
3. Imba yekuurayira neindasitiri yezvekudya
4. Petro-chemical industry - mafuta-mvura kuparadzaniswa
