Piv nrog rau cov organic polymer flocculants, microbial flocculants muaj qhov zoo xws li ntau yam flocculation, kev ua haujlwm siab, kev nyab xeeb, tsis yog - lom, thiab ib puag ncig tus phooj ywg. Tsis tas li ntawd, lawv tsim nyog rau ntau daim ntawv thov thiab nthuav dav dav -spectrum flocculation kev ua, ua rau lawv siv dav hauv kev siv dej thiab kev kho dej khib nyiab.
1. Kev kho mob siab -Concentration Organic Wastewater: High-Concentration organic wastewater feem ntau suav nrog cov tsiaj txhu pov tseg thiab lwm yam zaub mov thiab dej khib nyiab. Cov dej khib nyiab zoo li no feem ntau dhau los ua cov txheej txheem ua ntej xws li flocculation ua ntej kev kho biochemical. Microbial flocculants muaj cov nyhuv flocculation zoo dua li SPA (Special Purified Polymer) flocculants. Qhov no txhais tau hais tias yog tias cov microbial flocculants sib xyaw nrog ntau ntawm SPA ua ntej, cov nyhuv pretreatment ntawm cov dej khib nyiab tuaj yeem txhim kho ntxiv, thiab tag nrho cov tshuaj ntawm cov neeg ua haujlwm tuaj yeem txo qis.
2. Dyeing and Printing Wastewater: Dyeing and printing wastewater is characterized by its light color and complex composition, muaj dyes, sizing agents, auxiliaries, fibers, pos, waxes, organic salts, and other substances. Nws tseem yog ib qho ntawm cov teeb meem loj hauv kev kho cov dej khib nyiab hauv Suav teb. Lub ntsiab drawbacks ntawm qhov kev kho mob no yog: 1) siab COD thiab ib tug kuj B / C piv, ua rau tsis zoo scalability; 2) siab xim thiab complex muaj pes tsawg leeg. Tus yuam sij rau kev kho dyeing thiab luam ntawv cov dej khib nyiab yog nyob rau hauv decolorization. Ntawm ntau txoj kev kho mob, flocculation yog dav siv vim nws cov nqi peev tsawg, cov cuab yeej siv me me, muaj peev xwm kho me me, thiab tus nqi decolorization siab. Piv nrog rau cov kab mob microbial flocculants, polyferric flocculants tsis tsuas yog muaj cov flocculation zoo heev thiab sedimentation kev ua tau zoo tab sis kuj muaj cov txiaj ntsig zoo tshem tawm cov xim, muab lawv zoo dua li cov pa flocculants hauv dyeing thiab luam ntawv kho dej khib nyiab.
3. Kev Kho Mob Siab -Concentration Organic Suspended Wastewater: High-concentration organic suspended wastewater yog hom dej khib nyiab uas tsis tuaj yeem kho tau zoo. Cov txheej txheem tsoos feem ntau yog siv tshuaj flocculation thiab kho. Microbial flocculants kuj tseem siv tau los kho cov qauv dej xws li kaolin, av slurry, thiab ya tshauv. Hauv kev sim, microbial flocculants tau siv los kho cov dej khib nyiab ceramic, dej khib nyiab, thiab dej khib nyiab hauv lub cev.
4. Qhov ua tau zoo ntawm cov sludge hauv kev kho cov dej khib nyiab feem ntau yuav txo qis vim qhov tsis zoo ntawm cov sludge cov khoom ua kom zoo dua qub. Ntxiv cov microbial flocculants rau activated sludge tuaj yeem txo cov sludge ntim index sai, tiv thaiv sludge flocculation, tshem tawm cov sludge shrinkage, thiab yog li rov ua kom cov sludge refining muaj peev xwm, txhim kho tag nrho cov efficiency ntawm kev kho mob.
Raws li hom tshiab ntawm flocculant, microbial flocculants muaj cov ntawv thov zoo heev thiab tau siv dav hauv kev kho mob siab -cov dej khib nyiab organic, dye water wastewater kho, activated sludge treatment, and other wastewater treatment applications, demonstrateful vitality.
