A cikin ayyukan kula da najasa na diatomite, ana aiwatar da matakai daban-daban kamar su neutralization, flocculation, adsorption, sedimentation da tacewa na najasa sau da yawa.Diatomiteyana da kaddarorin jiki da sinadarai na musamman. Diatomite zai iya inganta neutralization, flocculation, adsorption, sedimentation da tacewa na najasa dakatar da daskararru a cikin najasa jiyya tsari ta daban-daban gyare-gyare matakai kamar pulverization, bushewa, selection da calcination. Aiki.

Babban ka'idar kula da najasa diatomite:

1. Inter-barbashi dipole hulda: Ana caje saman diatomite barbashi da kuma iya adsorb dipolar kwayoyin (atom) na iyakacin duniya kafofin watsa labarai, haifar da wadannan dipole kwayoyin (atom) zuwa spontaneously unipolar fuskantarwa a saman diatomite. Lokacin da aka sanya diatomite a cikin najasa, ainihin ma'auni na polarity na tsarin najasa ya karye, kuma ƙarfin dipole yana aiki don inganta haɗin gwiwar ƙwayoyin colloidal da kwayoyin polar (atom) a cikin najasa a saman duniyar diatomaceous don samar da agglomeration. Sauƙi don rabuwa.

2. Flocculation: Flocculation wani tsari ne wanda ƙananan barbashi ko agglomerates na ƙananan barbashi ke haifar da manyan flocs. Ƙara gyare-gyaren diatomaceous ƙasa zuwa najasa da aiwatar da tashin hankali da tsufa na tsarin watsawa na iya haifar da manyan gungun abubuwa masu cutarwa a cikin najasa da sauri. Wannan babban ci gaba ne a cikin tsattsauran rabe-rabe na najasa, wanda ba wai kawai rage farashin kula da gurbatar yanayi ba ne, har ma yana inganta haɓakar rabuwa.

3. Adsorption: Adsorption shine tasirin saman. The surface na diatomaceous ƙasa tare da babban watsawa yana da babban surface free makamashi kuma yana cikin wani sosai thermodynamically m jihar, don haka yana da hali to adsorb sauran abubuwa don rage surface makamashi. Diatomaceous ƙasa na iya adsorb ƙungiyar flocculation, wasu ƙwayoyin cuta na kwayan cuta da ultra-lafiya particulate kwayoyin halitta a cikin najasa zuwa ciki da waje surface na diatom jiki, forming wani babban barbashi kungiyar tsakiya a kan diatom jiki. Bugu da ƙari, ƙasa diatomaceous ita ma hanya ce mai kyau ga ƙananan ƙwayoyin cuta, don haka yana da kyau mai ɗaukar nauyin kwayoyin halitta a cikin ayyukan kula da kwayoyin halitta na najasa.

4. Filtration: Diatomite ba shi da inganci. Bayan an ƙara wani gyare-gyaren diatomite a cikin najasa, zai iya yin sauri da sauri don samar da gado mai ƙarfi mai ƙarfi, wanda ya dace da sludge dewatering da kuma kawar da slag. Ana tace ruwan najasar ta cikin gadon tacewa ta yadda za a kama manyan ƙwayoyin cuta, fungi, flocculation groups, da barbashi a cikin tsari kuma a tace su. Jerin diatomite masu kula da najasa da aka samar da kamfaninmu ta amfani da fasahar gyare-gyare ana amfani da su sosai wajen kula da najasa na masana'antu da na birni. Masu amfani za su iya zaɓar ɗaya ko fiye da gwaje-gwaje masu haɗaka bisa ga takamaiman yanayi don cimma tasirin da ake so.

An ba wa farar ƙasa suna bayan launin ruwan toka-fararen ɓangaren litattafan almara a ƙarƙashin humus Layer. An rarraba shi a cikin tudun tsaunuka na gabas da kwaruruka na arewa maso gabashin China, yanayin yana da ɗanshi, kuma nau'in ciyayi shine tsire-tsire masu tushe mara zurfi. Tarin kwayoyin halitta na ƙasa bai kai na ƙasa baƙar fata ba. Saboda rashin lalacewa na kwayoyin halitta, sau da yawa yana da halaye na peatification. Abubuwan da ke cikin kwayoyin halitta a cikin saman ƙasa na ƙasan albic Har zuwa 8-10%, rubutun da ke ƙarƙashin albic Layer shine yawancin loam da yumbu mai nauyi; layin albic yana da ɗan haske a cikin rubutu, kuma leach ɗin ƙarfe a bayyane yake. Ma'adinan yumbu shine yafi hydromica tare da ƙananan adadin kaolinite da amorphous abu.

Duniyar diatomaceous ta ƙunshi SiO2 amorphous, kuma ta ƙunshi ƙaramin adadin Fe2O3, CaO, MgO, Al2O3 da ƙazantattun kwayoyin halitta. Duniyar diatomaceous yawanci rawaya ne ko launin toka mai haske, mai laushi, mai laushi da haske. Ana amfani da shi sosai a masana'antu azaman kayan rufewa, kayan tacewa, filaye, kayan abrasive, albarkatun gilashin ruwa, masu lalata launi da masu ɗaukar hoto. Za'a iya lura da sifar ƙura ta musamman na duniya diatomaceous a ƙarƙashin na'urar hangen nesa. Wannan tsarin microporous shine dalilin halayen halayen jiki da sinadarai na duniya diatomaceous. Babban bangaren diatomaceous ƙasa a matsayin mai ɗauka shine SiO2. Duniyar diatomaceous gabaɗaya tana samuwa ne ta ragowar silicate bayan mutuwar algae mai sel guda ɗaya da ake kira diatoms, kuma ainihinsa shine SiO2 mai ɗauke da ruwa. Diatoms a cikin ruwa mai dadi kuma Akwai nau'ikan diatoms da yawa waɗanda zasu iya rayuwa a cikin ruwan gishiri. Gabaɗaya, ana iya raba su zuwa “tsakiyar oda” diatoms da “odar famfo” diatoms. A cikin kowane tsari, akwai “genus” da yawa, wanda yake da rikitarwa sosai. Babban abin da ke cikin ƙasa diatomaceous na halitta shine SiO2, masu inganci masu inganci fari ne, kuma abun cikin SiO2 yakan wuce 70%. Monomer diatoms ba su da launi kuma masu gaskiya. Launin duniya diatomaceous ya dogara da ma'adinan yumbu da kwayoyin halitta. Abubuwan da ke tattare da diatoms akan ma'adanai daban-daban sun bambanta. Diatomaceous Earth shine burbushin diatomaceous diatomaceous ajiya da aka samu bayan mutuwar wani tsiro mai kwayar halitta da ake kira diatom bayan tarawa na kimanin shekaru 10,000 zuwa 20,000. Diatoms suna ɗaya daga cikin protists na farko da suka bayyana a duniya, suna zaune a cikin ruwan teku ko ruwan tafkin. Wannan diatom ne ke ba da iskar oxygen ga ƙasa ta hanyar photosynthesis kuma yana haɓaka haihuwar mutane, dabbobi da tsirrai.
