%X Using the entrapped immobilized cells for treating wastewater is a new technique of biological treatment, but the entrapping agents are so expensive that application of them will be limited. The authors have developed polyvinyl alcohol (PVA) as an entrapping agent with PVA-boric acid method, and have prepared porous PVA-pellets for treating detergent wastewater. The results show that the PVA-pellets have high mechanical stability, good preservative ability, good recovery of activity, nearly no sludge produced, and viability of entrapped sells.
