真菌菌株的固定化及其在印染废水处理中的应用
Immobilization and application of fungus in dyeing-wastewater treatment
摘要
Abstract
The fungus screened from soil was enclosed in the hydrogel beads made from polyvinyl alcohol and sodium alginate. PVA beads were investigated in terms of chemical stability, mechanical stability, swelling ratio, per-meability, microstructure and cytotoxicity. The decolorization efficiency of the immobilized fungus on different artificial dyeing wastewater and real dyeing water from plant were investigated. The results revealed that the PVA beads have high mechanical and chemical stability, good permeability, low cytotoxicity. The decolorizations of direct sky blue 5B and direct fast scarlet 4BS were mainly due to the adsorption of dyes by fungus and the decol-orization rate of dye reached 92%!and 59%"after"5"days, respectively. However, the decolorizations of acid red 3R and real dyeing wastewater from plant were caused mainly by the biological degradation and the decolorization rate of dye both reached about 90%!after 5 days. Furthermore, immobilized fungus exhibited excellent reusability and its decolorization rate for acid red 3R reached 92%!after four repeat using.关键词
