摘　　要：利用黑曲霉菌丝球处理豆制品废水的优点是黑曲霉安全性好、菌丝球易收获、利于降低成本且可以减少传统处理方式所产生的污泥量。在前期研究的基础之上,在搅拌式发酵罐中考察了黑曲霉菌丝球降低豆制品废水化学需氧量（COD）的条件。研究结果表明,当豆制品废水初始COD在2×10~3mg/L,黑曲霉孢子浓度为1.44×10~3/L时,黑曲霉的菌丝能够在搅拌式发酵罐中形成形态均一的菌丝球,同时可将废水的COD降至842 mg/L,COD去除率达55.7%。该研究结果为在搅拌式发酵罐中利用黑曲霉菌丝球处理豆制品废水提供了参考依据。Aspergillus niger pellet is a good approach for soybean wastewater treatment because of its good safety record,easy recovery of pellets morphology,low cost and low sludge production. On the basis of previous research,Aspergillus niger was cultivated in mechanical agitated fermentor to form pellets and treat soybean wastewater. The condition of reducing chemical oxygen demand（ COD） of wastewater by using Aspergillus niger pellets was investigated. Research results showed that when the initial COD of wastewater and initial spore concentration were 2 × 10~3 mg / L and 1. 44 × 10~3/ L respectively,the uniform mycelium pellets could be observed in the fermentor. COD reduced to 842 mg / L and the removal rate of COD reached 55. 7%. This result provided a reference basis for treating soybean wastewater using Aspergillus niger pellets in stirring-type fermentor.
