Preparation of Composite Carrier Material Immobilized Activated Sludge and Application in Treating Wastewater

Abstract:

Article Preview

The optimum preparation conditions of polyvinyl alcohol (PVA) immobilized activated sludge are investigated, the results show that the concentration of the entrapping agents PVA is 10%(W/V), the mass ration of the activated sludge and entrapping agents is 1∶1(W/V) and the crosslinking time is 24 h. Pelletability and mass transfer property of immobilized activated sludge are improved by adding 1% sodium alginate (SA) into entrapping agents, the intensity of immobilized activated sludge and COD removal rate of oil wastewater can be increased simultaneously by using inorganic composited carrier material.
