Kwinkqubo yonyango lwegesi yenkunkuma, ingakumbi xa kunyangwa igesi yenkunkuma yemizi-mveliso equlethe ii-VOC (ezifana nokuprinta, ukupeyinta, kunye neshishini leekhemikhali), umgubo womhlaba we-diatomaceous unokufunxa izinto eziyingozi ngempumelelo. Ulwakhiwo olunemingxuma lomgubo we-diatomite luneendawo ezininzi zokufunxa, ezinokubamba iimolekyuli ze-VOC ngokusebenzisa amandla e-van der Waals kunye nokutsala kwe-electrostatic. Emva kokutshintsha umphezulu womgubo womhlaba we-diatomaceous (njengokufaka i-activated carbon, i-titanium dioxide, njl.njl.), amandla ayo okufunxa ii-VOC anokuphuculwa ngakumbi. Ukuthatha indawo yokusebenzela yokupeyinta yesityalo sokwenza iimoto njengomzekelo, igesi yenkunkuma inenani elikhulu le-benzene, i-toluene, kunye ne-xylene. Emva kokudlulisa igesi yenkunkuma kwindawo yokucoca egcwele umgubo womhlaba we-diatomaceous oguquliweyo, izinga lokususa i-benzene, i-toluene, kunye ne-xylene linokufikelela ngaphezulu kwe-90%, kwaye uxinzelelo lwe-VOCs kwigesi yenkunkuma elungisiweyo luphantsi kunomgangatho wesizwe wokukhupha (≤80 mg/m³). Xa kuthelekiswa nokufunxwa kwekhabhoni esebenzayo yendabuko, i-diatomaceous earth powder ineengenelo zokuba nexabiso eliphantsi, ubomi obude (ixesha lokufunxwa liphindwe ka-2-3 kunelekhabhoni esebenzayo), kunye nokuvuselelwa okulula (kunokuvuselelwa ngokutsha ngokufudumeza kwi-300-400°C, kwaye amandla okufunxwa angabuyiselwa ngaphezulu kwe-85% emva kokuvuselelwa).

Ekunyangweni kwegesi yenkunkuma enuka kamnandi (njengezityalo zonyango lwenkunkuma, izityalo zonyango lwelindle, kunye neefama zemfuyo), umgubo womhlaba we-diatomaceous ungadlala indima entle ekususeni ivumba elibi. Izinto ezinuka kamnandi ziquka i-ammonia, i-hydrogen sulfide, kunye ne-mercaptans. Ulwakhiwo olunemingxuma lomgubo we-diatomite lunokufunxa ezi molekyuli zinuka kamnandi, kwaye amaqela asebenzayo e-alkaline okanye e-acidic kumphezulu wawo (emva kokuguqulwa) anokusabela nezinto ezinuka kamnandi ukuze azibolise zibe zizinto ezingenabungozi. Isityalo sonyango lwenkunkuma kwisixeko esiselunxwemeni sasebenzisa inkqubo yokususa ivumba elibi esekelwe kumgubo womhlaba we-diatomaceous. Emva kokufakwa, uxinaniso lwevumba elijikeleze isityalo lwancitshiswa ukusuka kwi-5000 OU/m³ ukuya ngaphantsi kwe-200 OU/m³, eyayiphantsi kakhulu kunomgangatho wesizwe (≤400 OU/m³), kwaye izikhalazo ezivela kubemi abakufutshane zancitshiswa nge-90%. Kwangaxeshanye, umgubo womhlaba we-diatomaceous osetyenziswa kwinkqubo yokususa ivumba unokusetyenziswa kwakhona emva kokuvuselelwa, ukunciphisa inani lenkunkuma eqinileyo eveliswayo.​

Kwindlela yokucoca amanzi amdaka, umgubo womhlaba we-diatomaceous ofunxa kakhulu ungasetyenziselwa ukunyanga amanzi amdaka emizi-mveliso anezinto ezingcolisa izinto eziphilayo (ezifana nokuprinta nokudaya amanzi amdaka, amanzi amdaka ekhemikhali). Ukuprinta nokudaya amanzi amdaka kuqulathe inani elikhulu leedayi kunye nezinto ezincedisayo, ezine-chroma ephezulu kunye ne-COD, kwaye kunzima ukuzibola. Ukongeza umgubo womhlaba we-diatomaceous oyi-2-5% emanzini amdaka kunokufunxa idayi kunye nezinto eziphilayo emanzini. Uvavanyo lubonisa ukuba izinga lokususa i-chroma lokuprinta nokudaya amanzi amdaka linokufikelela ngaphezulu kwe-95%, kwaye izinga lokususa i-COD linokufikelela kwi-60-80%. Xa kuthelekiswa nee-coagulants zemveli (ezifana ne-aluminium sulfate), umgubo womhlaba we-diatomaceous awunangcoliseko lwesibini (akukho aluminium ion residue), kwaye udaka oluveliswa emva konyango kulula ukulufunxa kwaye lunokusetyenziswa njengesongezelelo sezinto zokwakha emva konyango olungenabungozi. Umzi-mveliso wokuprinta nokudaya eZhejiang usebenzise umgubo womhlaba we-diatomaceous ukunyanga amanzi amdaka awo. Emva kokucoca, amanzi amdaka anokuphinda asetyenziswe ukuze asetyenziswe (emva kokucoca okuphucukileyo), kuncitshiswe ukusetyenziswa kwamanzi ngumzi-mveliso ngama-30% kwaye kongiwe iindleko ezininzi zamanzi.

Umgubo wethu womhlaba we-diatomaceous ofunxa kakhulu ukhuseleko lokusingqongileyo uneentlobo ngeentlobo zemveliso, kuquka umgubo, i-granular, kunye ne-extruded. Uhlobo lomgubo (100-800 mesh) lufanelekile kwiinqaba zokufunxa amanzi amdaka kunye negesi yenkunkuma; uhlobo lwe-granular (1-5 mm) lufanelekile kwiinkqubo zokufunxa ezizinzileyo kunyango lwegesi yenkunkuma; uhlobo olufunxayo (5-10 mm) lufanelekile kwiiprojekthi ezinkulu zonyango lwegesi yenkunkuma enomthamo ophezulu womoya. Izalathisi eziphambili zobugcisa zeemveliso zethu zezi: indawo ethile yomphezulu ≥200 m²/g, umthamo we-pore ≥0.8 cm³/g, umthamo wokufunxa we-methylene blue ≥15 mL/0.1g, kunye nomxholo womswakama ≤3%. Singabonelela ngeemveliso zepowder yomhlaba ye-diatomaceous eguquliweyo ngokwezinto ezithile zonyango zabathengi, ezifana nepowder ye-diatomite elayishwe ngekhabhoni (ye-VOCs adsorption), ipowder ye-diatomite elayishwe nge-titanium dioxide (yokudilizwa kwe-photocatalytic kwezinto ezingcolisayo eziphilayo), kunye nepowder ye-alkaline diatomite (ye-hydrogen sulfide adsorption).​

Kwinkqubo yemveliso, sisebenzisa ubuchwepheshe obuphambili bokusebenza ukuphucula amandla okufunxa i-diatomaceous earth powder. Inkqubo yokuqalisa ibandakanya ukusebenza kwe-asidi (ukusebenzisa i-dilute sulfuric acid ukuqhekeza umphezulu wee-diatomite particles, ukwandisa inani lee-pores) kunye nokusebenza kwe-thermal (ukwenza i-calcine kubushushu obuphezulu ukususa ukungcola kwezinto eziphilayo kwii-pores nokwandisa ubungakanani be-pore). I-activated diatomaceous earth powder inendawo ethile yomphezulu eyonyuswe ngama-30-50% xa kuthelekiswa ne-ore yokuqala, kwaye amandla okufunxa aphuculwe kakhulu. Ibhetshi nganye yeemveliso iya kuvavanywa amandla okufunxa (ukusebenzisa isisombululo se-methylene blue njenge-adsorbate) kunye novavanyo lwesakhiwo se-pore (ukusebenzisa i-analyzer yendawo ethile yomphezulu), ukuqinisekisa ukuba ukusebenza kwemveliso kuyahlangabezana neemfuno.​
