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... 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。 展开更多

The behavior of industrial cluster is similar to the behavior of biological population, that is, the industrial cluster is seemed to be an ecological symbiotic system. The relationship between economic organizations in the industrial cluster is similar to the relationship of species in ecological system, and symbiotic reciprocity, competition and cooperation are the basic. The ecological development is mainstream and direction of industrial cluster. In this paper, firstly, we studied the ecological symbiosis growth model of industry cluster, and tbund it being according to logistic growth model; secondly, we studied the growth and reproduction of economic organizations in industrial cluster in three different cases, which with only competition relations, only beneficial relations, and both competition and beneficial cooperation relationship between economic organizations, and finally, we determined the number of economical organizations when the industrial cluster attained ecological equilibrium. 展开更多
