Ib feem ntawm cov organic teeb meem yog synthesized rau hauv cov hlwb tshiab thiab ib feem yog oxidized rau CO2 thiab dej los ua kom muaj zog. Hauv activated sludge systems cov hlwb tshiab tsim nyob rau hauv cov tshuaj tiv thaiv yog tshem tawm los ntawm cov kua kwj nyob rau hauv lub daim ntawv ntawm flocculent sludge nyob rau hauv lub tank.

Hais txog qhov no, yuav ua li cas activated sludge tsim?

Cov txheej txheem cuam tshuam nrog huab cua lossis oxygen tau nkag mus rau hauv kev sib xyaw ntawm cov tshuaj ntsuam xyuas, thiab thawj cov dej phwj kho lossis cov dej khib nyiab (dej khib nyiab) ua ke nrog cov kab mob los tsim cov khoom siv roj ntsha uas txo cov organic cov ntsiab lus ntawm cov dej phwj tuaj. Qhov feem ntawm floc no hu ua rov qab activated sludge (R. A. S.).

Tom qab, lo lus nug yog, qhov twg yog siv cov sludge? Lub Hom Phiaj. Nyob rau hauv ib tug dej phwj (los yog industrial wastewater) kho nroj tsuag, lub activated sludge txheej txheem yuav ua tau siv rau ib lossis ob peb lub hom phiaj hauv qab no: oxidizing carbonaceous teeb meem: biological teeb meem. oxidizing nitrogeneous teeb meem: feem ntau ammonium thiab nitrogen hauv cov ntaub ntawv lom.

Nyob rau hauv tas li ntawd, dab tsi yog activated sludge txoj kev?

Qhib - txoj kev sludge , dej phwj-kho txheej txheem uas sludge , cov kab mob uas nplua nuj deposits ntawm cov tso tsheb hlau luam thiab cov phiab, yog noob rau hauv cov dej khib nyiab tuaj thiab cov sib tov sib xyaw ua rau ob peb teev nyob rau hauv lub xub ntiag ntawm huab cua txaus.

Yuav ua li cas activated sludge siv los ntxuav cov dej phwj tuaj?

Cov activated sludge yog aerated rau yaj oxygen uas tso cai rau cov organic teeb meem (BOD) siv los ntawm cov kab mob. Cov organic teeb meem, los yog zaub mov, sticks rau lub activated sludge . Cov pa oxygen yaj hauv dej tso cai rau cov kab mob siv cov khoom noj (BOD) thiab tseem hloov cov ammonia rau nitrate.
