摘要

摘要: 为提升生物制药废水处理效率，以某制药厂的右旋糖酐废水作为主要发酵原料，设计2种不同循环流化的水力搅拌方案，进行653.5 L规模的厌氧消化对比中试试验。1号罐为底部进水高位集中压力出水（单口），4号罐为底部进水高位分散式压力出水（四口）。28 d连续发酵实验表明，1号罐较不搅拌的对照组（0号罐）的产气率和COD去除率分别提升了45%和20%，4号罐则分别提升了58%和24%。研究结论可为指导右旋糖酐废水产气潜能提升设计和进一步机理研究提供借鉴。

Abstract: In this paper, in order to improve the treatment performance, the dextran wastewater from a pharmaceutical factory was used as the main fermentation raw material to carry out biogas production experiments in three 653.5 L anaerobic digesters. Digester I adopted the circulating fluidization hydraulic mixing scheme of a high-position, centralized pressure outlet (single port), and digester IV adopted a high-position, dispersed pressure outlets (four ports). The 28-day continuous fermentation experiment showed that the biogas production and COD removal rate of digester I was increased by 45% from the control group without mixing, and the COD removal rate was increased by 20% from the control group. The biogas production of digester IV was increased by 58%, and the COD removal rate was increased by 24%, from the control group.The research results could provide reference to guide the design of dextran wastewater gas production potential enhancement and further mechanism researches.
