Preparation of Composite Carrier Material Immobilized Activated Sludge and Application in treating wastewater

摘要：

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.
