染料废水具有COD高、色度高、盐度高和BOD/COD比值低等特点,属于难生化降解的有机工业废水.白腐真菌对可生化性差、有毒有害的废水有较好的降解作用.利用固定化微生物技术可构成一种高效、快速、能连续处理的废水处理系统,减少二次污染.实验采用固定化白腐真菌处理染料废水,分别考察了不同生物球的投加量、染料废水浓度、pH、转速对染料脱色率的影响.结果表明:固定化白腐真菌对染料废水分别在生物球投加量为5.5 g/100 m L、染料废水浓度为20 mg/L、pH为3、转速为120 r/min条件下具有最好的脱色率.
染料廢水具有COD高、色度高、鹽度高和BOD/COD比值低等特點,屬于難生化降解的有機工業廢水.白腐真菌對可生化性差、有毒有害的廢水有較好的降解作用.利用固定化微生物技術可構成一種高效、快速、能連續處理的廢水處理繫統,減少二次汙染.實驗採用固定化白腐真菌處理染料廢水,分彆攷察瞭不同生物毬的投加量、染料廢水濃度、pH、轉速對染料脫色率的影響.結果錶明:固定化白腐真菌對染料廢水分彆在生物毬投加量為5.5 g/100 m L、染料廢水濃度為20 mg/L、pH為3、轉速為120 r/min條件下具有最好的脫色率.

Dye wastewater is difficult to biodegrade which belongs to organic industrial wastewater with high COD ,high chromaticity ,high salinity and low BOD/COD ratio etc . The white-rot fungus has quite good degradation on poor biodegradability ,toxic and hazard-ous wastewater .Using the immobilized microorganism technology can constitute a highly ef-ficient ,rapid and continuous processing of wastewater treatment system and reduce the sec-ondary pollution effectively .The dye wastewater was treated by immobilized white-rot fun-gus ;and the influence of the different mass of biological balls ,concentration of dye wastewater ,the values of pH ,rotational speed on the decolorization rates was examined .The results show that :when the mass of biological balls is 5 .5 g/100 mL ,the concentration of dye wastewater is 20 mg/L ,pH is 3 ,the rotational speed is 120 r/min ,the decolorization rate of dye wastewater reach the best respectively .
