Ekuphatheni igesi engcolile, ikakhulukazi ekwelapheni igesi engcolile yezimboni equkethe ama-VOC (njengokunyathelisa, ukupenda, kanye nemboni yamakhemikhali), i-diatomaceous earth powder ingamunca izinto eziyingozi ngempumelelo. Isakhiwo esinezimbobo se-diatomite powder sinezindawo eziningi zokumunca, ezingabamba ama-molecule e-VOC ngamandla e-van der Waals kanye nokukhanga kwe-electrostatic. Ngemva kokushintsha ubuso be-diatomaceous earth powder (njengokulayisha i-activated carbon, i-titanium dioxide, njll.), amandla ayo okumunca ama-VOC angathuthukiswa kakhulu. Uma sibheka indawo yokupenda yesitshalo sokukhiqiza izimoto njengesibonelo, igesi engcolile iqukethe inani elikhulu le-benzene, i-toluene, ne-xylene. Ngemva kokudlulisa igesi engcolile embhedeni wokuhlunga ogcwele i-diatomaceous earth powder eguquliwe, izinga lokususwa kwe-benzene, i-toluene, ne-xylene lingafinyelela ngaphezu kwama-90%, futhi ukuhlushwa kwama-VOC kugesi engcolile ephathwe kahle kuphansi kunezinga lokukhishwa likazwelonke (≤80 mg/m³). Uma kuqhathaniswa nokumuncwa kwekhabhoni okwenziwa ngendlela yendabuko, i-diatomaceous earth powder inezinzuzo zokuba nezindleko eziphansi, impilo yenkonzo ende (isikhathi sokumuncwa siphindwe izikhathi ezingu-2-3 kunesekhabhoni esebenzisiwe), kanye nokuvuselelwa okulula (kungavuselelwa ngokushisa ku-300-400°C, futhi amandla okumuncwa angabuyiselwa ngaphezu kuka-85% ngemva kokuvuselelwa).​

Ekwelapheni igesi yemfucuza enukayo (njengezindawo zokulungisa imfucuza, izindawo zokulungisa indle, kanye namapulazi ezilwane), i-diatomaceous earth powder nayo ingadlala indima enhle ekususeni iphunga. Izinto ezinukayo zifaka phakathi i-ammonia, i-hydrogen sulfide, kanye nama-mercaptan. Isakhiwo se-diatomite powder esinezimbobo singamunca lawa ma-molecule anephunga, kanti amaqembu asebenzayo e-alkaline noma e-acidic ebusweni bawo (ngemuva kokuguqulwa) angasabela nezinto ezinukayo ukuze azibolise zibe izinto ezingenangozi. Isitshalo sokulungisa imfucuza edolobheni elingasogwini sasebenzisa uhlelo lokususa iphunga olusekelwe ku-diatomaceous earth powder. Ngemva kokufakwa, ukugcwala kwephunga elizungeze isitshalo kwehlisiwe kusuka ku-5000 OU/m³ kuya ngaphansi kuka-200 OU/m³, okwakuphansi kakhulu kunendinganiso kazwelonke (≤400 OU/m³), kanti izikhalazo ezivela kubahlali abaseduze zehliswe ngo-90%. Ngesikhathi esifanayo, i-diatomaceous earth powder esetshenziswa ohlelweni lokususa iphunga ingasetshenziswa kabusha ngemva kokuvuselelwa, kuncishiswe inani lemfucuza eqinile ekhiqizwayo.​

Ekuhlanzweni kwamanzi amdaka, i-diatomaceous earth powder emuncwa kakhulu ingasetshenziswa ukwelapha amanzi amdaka asezimbonini aqukethe ukungcola okungokwemvelo (njengokuphrinta nokudaya amanzi amdaka, amanzi amdaka amakhemikhali). Ukuphrinta nokudaya amanzi amdaka kuqukethe inani elikhulu lamadayi kanye nezinsiza, ane-chroma ephezulu kanye ne-COD, futhi kunzima ukuwohloka. Ukwengeza i-diatomaceous earth powder engu-2-5% emanzini amdaka kungamunca udayi kanye nezinto eziphilayo emanzini. Ukuhlolwa kubonisa ukuthi izinga lokususwa kwe-chroma kwamanzi amdaka okuprinta nokudaya lingafinyelela ngaphezu kuka-95%, kanti izinga lokususwa kwe-COD lingafinyelela ku-60-80%. Uma kuqhathaniswa nama-coagulant endabuko (njenge-aluminium sulfate), i-diatomaceous earth powder ayinayo ingcoliso yesibili (ayikho i-aluminium ion residue), futhi udaka olukhiqizwa ngemva kokwelashwa kulula ukulumunca futhi lungasetshenziswa njengesengezo sezinto zokwakha ngemva kokwelashwa okungenangozi. Ifektri yokuphrinta nokudaya eZhejiang isebenzise i-diatomaceous earth powder ukwelapha amanzi ayo amdaka. Ngemva kokwelashwa, amanzi angcolile angaphinde asetshenziswe ukuze akhiqizwe (ngemuva kokwelashwa okuthuthukisiwe), kunciphisa ukusetshenziswa kwamanzi efektri ngo-30% futhi konge izindleko eziningi zamanzi.

Impuphu yethu yomhlaba ye-diatomaceous emunca kakhulu yokuvikela imvelo inezinhlobo ezahlukene zemikhiqizo, okuhlanganisa i-powder, i-granular, kanye ne-extruded. Ifomu lempuphu (100-800 mesh) lifanelekela ukwelashwa kwamanzi amdaka kanye nemibhoshongo yokumunca igesi emdaka; ifomu le-granular (1-5 mm) lifanelekela izinhlelo zokumunca ezimibhede eqinile ekwelapheni igesi emdaka; ifomu elikhishwe (5-10 mm) lifanelekela amaphrojekthi amakhulu okwelapha igesi emdaka enomthamo womoya ophezulu. Izinkomba zobuchwepheshe eziyinhloko zemikhiqizo yethu yilezi: indawo ethile yobuso ≥200 m²/g, umthamo we-pore ≥0.8 cm³/g, umthamo wokumunca we-methylene blue ≥15 mL/0.1g, kanye nokuqukethwe komswakama ≤3%. Singaphinde sinikeze imikhiqizo yempuphu yomhlaba ye-diatomaceous eguquliwe ngokwezinto ezithile zokwelapha zamakhasimende, njengempuphu ye-diatomite elayishwe nge-carbon (yokudonswa kwe-VOCs), i-titanium dioxide-loaded diatomite powder (yokudonswa kwe-photocatalytic kwezinto ezingcolisayo eziphilayo), kanye ne-alkaline diatomite powder (yokudonswa kwe-hydrogen sulfide).

Enqubweni yokukhiqiza, sisebenzisa ubuchwepheshe obuthuthukisiwe bokwenza kusebenze ukuze kuthuthukiswe amandla okumunca i-diatomaceous earth powder. Inqubo yokwenza kusebenze ifaka phakathi ukusebenza kwe-asidi (kusetshenziswa i-dilute sulfuric acid ukucwilisa ubuso bezinhlayiya ze-diatomite, ukwandisa inani lama-pores) kanye nokusebenza kokushisa (ukwenza i-calcine emazingeni okushisa aphezulu ukuze kususwe ukungcola okungokwemvelo kuma-pores futhi kwandiswe usayizi wama-pore). I-diatomaceous earth powder esebenzayo inendawo ethile yobuso ekhuliswe ngo-30-50% uma kuqhathaniswa ne-ore yokuqala, futhi amandla okumunca athuthukiswa kakhulu. Iqoqo ngalinye lemikhiqizo lizohlolwa amandla okumunca (kusetshenziswa isisombululo se-methylene blue njenge-adsorbate) kanye nokuhlolwa kwesakhiwo sama-pore (kusetshenziswa i-analyzer yendawo ethile yobuso), okuqinisekisa ukuthi ukusebenza komkhiqizo kuyahlangabezana nezidingo.​
