Mumapurojekiti ekurapa tsvina yediatomite, maitiro akasiyana-siyana senge neutralization, flocculation, adsorption, sedimentation uye kusefa kwetsvina inowanzoitwa.Diatomiteine zvinhu zvakasiyana-siyana zvemuviri nemakemikari. Diatomite inogona kusimudzira neutralization, flocculation, adsorption, sedimentation uye kusefa kwetsvina yakamiswa yakasimba mumararamiro ekuchenesa tsvina kuburikidza neakasiyana ekugadzirisa maitiro senge pulverization, kuomesa, kusarudzwa uye calcination. Basa.

Iyo yakakosha musimboti we diatomite sewage treatment:

1. Inter-particle dipole interaction: The surface of diatomite particles inochajiswa uye inogona kudsorb dipolar molecules (atomu) yepolar media, zvichiita kuti aya dipole molecules (maatomu) aite zvega unipolar orientation pamusoro pe diatomite. Kana iyo diatomite yaiswa mutsvina, iyo yekutanga polarity chiyero chetsvina system inotyoka, uye dipole simba rinoita kusimudzira kubatanidzwa kwecolloidal particles uye polar molecules (maatomu) mutsvina pamusoro penyika diatomaceous kuita agglomerations. Zviri nyore kuparadzanisa.

2. Flocculation: Flocculation inzira umo zvidimbu zvidiki kana agglomerates ezvimedu zvidiki zvinogadzira makuru maflocs. Kuwedzera yakagadziridzwa diatomaceous pasi kune tsvina uye kuita kushushikana uye kuchembera kurapwa kweiyo dispersion system inogona kukurumidza kuumba yakagadzikana yakakura flocs yezvinhu zvinokuvadza mutsvina. Uku ndiko kubudirira kukuru mukuparadzaniswa kwakasimba-mvura yetsvina, iyo isingangodzikisi mari yekudzora kusvibiswa, asiwo inovandudza kupatsanurwa kwakanaka.

3. Adsorption: Adsorption inobata kumeso. Kumusoro kwevhu re diatomaceous rine kupararira kukuru kune nzvimbo yakakura isina simba uye iri munzvimbo ine thermodynamically isina kugadzikana, saka ine tsika yekudyisa zvimwe zvinhu kuderedza pamusoro pesimba. Diatomaceous pasi inogona kushambadzira boka re flocculation, mamwe mabhakitiriya mavhairasi uye Ultra-yakanaka-chaicho chinhu mukati mesuweji kusvika mukati nekunze kwepamusoro pemuviri we diatom, kuumba boka guru rechikamu rakatarisana nemuviri we diatom. Uye zvakare, pasi diatomaceous zvakare yakanaka svikiro kune tupukanana, saka yakanaka kutakura kune microbial agents mumasewage biochemical treatment mapurojekiti.

4. Filtration: Diatomite isinganzwisisiki. Mushure mekunge imwe diatomite yakagadziridzwa yawedzerwa kune tsvina, inogona kukurumidza kugadzirisa kuti iite yakasimba porous sefa mubhedha, iyo yakanakira sludge dewatering uye slag kubvisa kurapwa. Iyo tsvina inosefa kuburikidza nesefa mubhedha kuitira kuti mavhairasi makuru, fungi, mapoka e flocculation, uye zvimedu zvinopindirwa uye kusefa kunze mukuita. Iwo akateedzana e diatomite sewage treatment agents anogadzirwa nekambani yedu achishandisa yakagadziridzwa tekinoroji anoshandiswa zvakanyanya mukurapa kwetsvina yemaindasitiri neyemumaguta. Vashandisi vanogona kusarudza imwe kana yakawanda inoumbwa miedzo zvinoenderana nemamiriro chaiwo kuti vakwanise kuita zvaunoda.

Ivhu jena rinotumidzwa zita re grey-white white pulp layer pasi pe humus layer. Yakagoverwa mumakomo ekumabvazuva uye mipata yeNortheast China, mamiriro ekunze ane mwando, uye mhando yezvinomera ndeye hygroscopic midzi isina kudzika midzi. Kuunganidzwa kwevhu organic zvinhu kushoma pane ivhu dema. Nekuda kwekusaora kwakashata kweorganic matter, kazhinji ine peatification maitiro. Izvo zviri mukati meiyo organic matter muchikamu chepamusoro chealbic ivhu Kusvika pa8-10%, magadzirirwo ari pasi pealbic layer anonyanya kurema loam nevhu; iyo albic layer haina kujeka mukugadzirwa, uye iron leaching iri pachena. Iyo mineral mineral inonyanya hydromica ine kaolinite shoma uye amorphous substance.

Diatomaceous pasi inoumbwa neamorphous SiO2, uye ine zvishoma zveFe2O3, CaO, MgO, Al2O3 uye organic tsvina. Diatomaceous pasi rinowanzo kujeka yero kana chiedza grey, nyoro, porous uye chiedza. Inowanzoshandiswa muindasitiri semidziyo yekuisa, sefa zvinhu, mafirita, abrasive zvinhu, girazi remvura mbishi zvinhu, decolorants uye catalyst vatakuri. Iyo yakakosha porous chimiro cheyakasikwa diatomaceous pasi inogona kucherechedzwa pasi pe microscope. Iyi microporous chimiro ndicho chikonzero chechimiro chemuviri uye chemakemikari zvimiro zvediatomaceous pasi. Chinhu chikuru chepasi diatomaceous semutakuri iSiO2. Diatomaceous pasi rinowanzo umbwa nemasara esilicate mushure mekufa kweimwe-sero algae pamwe chete inonzi diatoms, uye musimboti wayo imvura-ine amorphous SiO2. Diatoms mumvura yakachena uye Kune akawanda marudzi e diatoms anogona kurarama mumvura ine munyu. Kazhinji, vanogona kukamurwa kuva "central order" diatoms uye "plumbing order" diatoms. Mukurongeka kwega kwega, kune akawanda "genus", ayo akaomarara. Chinhu chikuru chezvisikwa diatomaceous pasi iSiO2, iyo yepamusoro-soro ichena muvara, uye zvinyorwa zveSiO2 zvinowanzopfuura 70%. Monomer diatoms haina ruvara uye yakajeka. Ruvara rwepasi diatomaceous rinoenderana nevhu zvicherwa uye organic zvinhu. Kuumbwa kwe diatoms pane zvakasiyana-siyana zvicherwa zvakasiyana. Diatomaceous earth ifossilized diatomaceous earth deposit yakaumbwa mushure mekufa kwechirimwa chine sero rimwe chete chinonzi diatom mushure menguva yekuunganidza makore angangoita 10 000 kusvika 20,000. Diatoms ndeimwe yevaratidziri vekutanga kuoneka panyika, vachigara mumvura yegungwa kana yegungwa. Ndiyo diatom iyi inopa oxygen kupasi kuburikidza nephotosynthesis uye inokurudzira kuberekwa kwevanhu, mhuka nezvirimwa.
