Treatment of Oil-containing Wastewater by Immobilized Yeast Cells
The oil-containing wastewater was treated by the immobilized yeast cells(pellets) and tbe effects of factors on immobilizations were studied . The pellets were prepared with polyvinyl alcohol(PVA)-sodium alginate(SA).The experimental results indicate that tbe optimized concentration of PVA and SA was 7% (w/v) and 1-3%(w/v), respectively. Furthermore, the process of preparing pellets was also investigated, and the optimized procedure was that the pellets were initially treated by CaCl2 solution with concentration of 2% for 6h , then immersed by the saturated solution of boric acid for another 18h. According to the above-mentioned method, pellets have high mechanical strength and mass transfer performance , and the final cell activity is about 80% .
