二相厌氧处理有机废水过程特性及生物相研究

Study on Characteristics of Organic Wastewater with Two-Phase Anaerobic Treatment

依据二相厌氧机理设计实验反应器,采用人工配制水样作为实验用水,利用色谱-质谱联动仪分析二相厌氧各阶段水质的特性。实验结果表明:经二相厌氧反应后,有机物的种类没有减少,相反增加了许多水解、酸化反应的小分子中间产物,产酸反应器将大分子难降解化合物降解为易降解酸性小分子化合物,可生化性有所提高,再经过产甲烷反应器最终处理后,出水的化合物种类和含量有明显减少。

Based on two -phase anaerobic mechanism, a processing reactor was designed; and the waste water with high concentration discharged in the process of production of Chinese traditional medicine is carefully analyzed by the use of GC- MS. The results obtained in the experiment show that the by -products of hydrolization and acidification increase instead of the reduction of organic matters＂ sort, and at the same time that the number and the amount of compounds in the eventual processed water are apparently reduced, the acid -producing reactor may decompose compounds with great molecule into those with small molecule and accordingly improve the biologically processing ability.
