Lub luag haujlwm ntawm adsorption choj
Lub tshuab ntawm adsorption bridging mas hais txog cov adsorption thiab bridging ntawm cov ntaub ntawv polymer thiab colloidal hais. Nws tseem tuaj yeem nkag siab tias ob qhov loj ntawm cov roj hmab sib thooj yog cov sib txuas ua ke vim tias qhov sib txawv ntawm cov roj hmab sib txawv. Polymer flocculants muaj cov kab teeb tsa, thiab lawv muaj cov pab pawg tshuaj lom neeg uas tuaj yeem cuam tshuam nrog qee qhov chaw ntawm cov nplaim ntawm cov xim sib txawv. Thaum cov siab polymer muaj qhov sib chwv nrog qhov sib xyaw ntawm colloidal, cov pawg tuaj yeem hnov mob nrog nplaim xim sib cais rau adsorb sib. Tus so ntawm lub polymer qauv yog ncab hauv kev daws teeb meem thiab tuaj yeem raug adsorbed rau cov colloidal hais nrog cov khoom seem ntawm lwm qhov chaw, kom cov polymer ua raws li kev sib txuas. Yog tias muaj tsawg dua cov khoom colloidal, cov lus hais saum toj siab polymer ncav cuag ib feem tsis ua raws li qhov thib ob colloidal hais, thiab lub qhov ncab yuav raug adsorbed rau lwm qhov chaw sai dua lossis tom qab los ntawm cov khoom qub colloidal, thiab cov polymer tsis tuaj yeem ua haujlwm ua tus choj , thiab colloidal particles Nws yog nyob rau hauv lub xeev ruaj khov. Thaum qhov ntau npaum ntawm cov pa roj-molecular flocculant loj dhau lawm, saum npoo ntawm cov roj hmab particle yuav raug xoob los tsim cov tshuaj ua kom rov muaj zog. Yog hais tias cov briquettes uas tau muab bridged thiab flocculated yog raug rau kev sib cav sib ceg ntev ntev, tus ntoo txuas yuav raug cais tawm ntawm lub npoo ntawm lwm qhov colloidal hais thiab rov thau rov qab mus rau saum npoo ntawm cov colloidal hais, uas ua rau lub xeev ruaj khov Cov.
