摘要：

针对黄姜皂素废水的特征采用三种不同的厌氧处理工艺对其进行静态厌氧处理试验,在试验条件相同的条件下,测得三种厌氧工艺的处理效果。试验表明,三段式两相厌氧工艺处理后的出水残留COD在相同时段内明显低于两相厌氧工艺和单级厌氧工艺。通过对其处理过程的产气动力学分析,得出三种厌氧工艺的动力学参数,并分析了三段式两相厌氧工艺优于其他厌氧工艺的机理及缘由。

Abstract:

An intermittent trial with three types of anaerobic digestion processes in the similar conditions has been investigated in viewof the characters of saponin wastewater and the effects of those processes have been determined.The experimental results demonstrates that the effluent remainder COD of two-phases anaerobic digestion with three stages is obviously lower than that of monopole anaerobic digestion and that of two-phases anaerobic digestion during the same period of time.Moreover,kinetic parameters of the three types anaerobic digestion processes is determined by analysing those aerogenical kinetic model.The mechanism and reasons for that two-phases anaerobic digestion with three stages is superior to the other two types of anaerobic digestion processes is analyzed.

Key words: saponin wastewater, anaerobic digestion, acidification, inner electrolysis, methane phase
