摘要
在含硫酸盐有机工业废水的厌氧处理过程中,硫酸盐还原菌和产甲烷菌以及产乙酸菌之间的竞争是不可避免的,值得注意的是有些硫酸盐还原菌可以和产甲烷菌或产乙酸菌构成一个有效的降解丙酸和丁酸的共生生物群。从增长动力学上看,硫酸盐还原菌在底物的竞争中占有明显的优势,但是有些因素诸如:温度,pH,以及游离态硫化氢的浓度也影响到它们之间的竞争关系。有几种硫酸盐还原菌还可以像发酵菌和产乙酸菌那样进行代谢活动。
In the treatment of organic wastewater containing sulfate, dealing with the competition between sulfate reducing and methane producing or acetogenic bacteria is inevitable. The syntrophic sulfate reducing and methanogenic consortia or the syntrophic acetogenic and sulfate reducing bacteria consortia can be an excellent path way to degrade propionate and butyrate. From the view of kinetic properties, SRB can be in the overwhelming position in the substrate competition, but factors such as pH, temperature and sulfide concentration etc. may affect the competition. Several kinds of sulfate reducing bacteria are capable of metabolizing as fermentive and aceteogenic bacteria.
