Iyo diatomite sefa yerubatsiro inonyanya kuteya zvimedu zvetsvina zvakamiswa mumvura pamusoro uye chiteshi chepakati kuburikidza neanotevera mabasa matatu, kuitira kuti uwane chinangwa chekuparadzaniswa kwakasimba-mvura.

1. Sieving effect Iyi inzvimbo yekusefa. Kana iyo mvura inoyerera nepasi diatomaceous, ma pores epasi diatomaceous madiki pane particle size yetsvina particles, saka tsvina yetsvina haigoni kupfuura uye inobatwa. Mhedzisiro iyi inonzi Yekutarisa maitiro. Muchokwadi, pamusoro pekeke resefa inogona kutariswa sesefa yepasi ine yakaenzana avhareji pore saizi. Kana hupamhi hwezvikamu zvakasimba zvisingasviki (kana zvishoma zvishoma kudarika) dhayamita ye pores ye diatomite, zvimedu zvakasimba "zvichapepetwa kubva pakumiswa". Kupatsanura kunze, tamba chinzvimbo chekusefa pamusoro.

2. Kudzika mhedzisiro Kudzika mhedzisiro ndiko kuchengetedza mhedzisiro yekusefa kwakadzika. Mukutsvaira kwakadzika, nzira yekuparadzanisa inongoitika mu "mukati" yepakati. Chikamu chezvimedu zvidiki zvisina kuchena zvinopinda pamusoro pekeke resefa zvakavharwa neiyo tortuous microporous chiteshi mukati mediatomaceous pasi uye madiki pores mukati mesefa keke. Rudzi urwu rwezvikamu zvinowanzova diki pane ma micropores ediatomaceous pasi. Kana zvimedu zvinorova madziro echiteshi, zvinogona kusiya kuyerera kwemvura. Zvisinei, kana inogona kusvika panguva ino inobva pane simba risina simba uye kushorwa kwezvikamu. Balance, rudzi urwu rwekubata uye kuongorora kwakafanana muzvisikwa, zvese ndezvemuchina chiito. Iko kugona kusefa kunze kwakasimba zvimedu zvinongoenderana nehukuru hwehukama uye chimiro chezvimedu zvakasimba uye pores.

3. Adsorption Iyo adsorption yakasiyana zvachose kubva pamusoro apa maitiro maviri ekusefa. Muchokwadi, mhedzisiro iyi inogona zvakare kutariswa seye electrokinetic kukwezva, iyo inonyanya kuenderana nepamusoro pezvinhu zveiyo yakasimba particles uye diatomaceous pasi pachayo. Kana zvimedu zviya zvine maburi madiki ari muvhu re diatomaceous pazvinodhumhana mukati meiyo porous diatomaceous pasi, zvinokwezvwa nemhosva dzakapesana. Kune zvakare rudzi rwekukwezvana pakati pezvimedu kuita masumbu uye kunamatira kune diatomaceous pasi. Ose ari maviri ndee adsorption, uye adsorption yakanyanya kuoma kupfuura maviri apfuura. Zvinowanzotendwa kuti chikonzero nei zvimedu zvidiki zvidiki pane dhayamita yepore zvakabatwa zvinonyanya kukonzerwa ne: (1) Intermolecular forces (inonziwo van der Waals attraction), kusanganisira dipoles Effect, induced dipole effect uye instant dipole effect; (2) kuvapo kweZeta inogona; (3) ion exchange process

Kubva pane matatu ari pamusoro pemabasa, mune net pressure filtration process yekumiswa, iyo yakasununguka granular diatomite sefa yerubatsiro inoshandiswa sesefa yepakati, iyo inonyanya kupa mapores akawanda sezvinobvira kune sefa yepakati layer, keke yekusefa, uye kugadzira Iyo spacer layer yemapores inobvumira kumiswa kupfuudza madiki pores echivhariso dhizaini, uye inoteya chidimbu chemvura inoyerera. pakati, kuitira kuti yakasimba uye mvura zviparadzaniswe.
