The floating bed is a kind of ecological restoration technology conducted by the absorbing of plant roots and the activities of the microbial to solving the problem of eutrophication. This article is based on the experiment of the floating bed cultivated swamp cabbage inside the greenhouse,measuring the amount of the denitrification bacteria using regularly by the PFU method,compared with the content of total nitrogen in water,analyzing the characteristics of the denitrification bacteria and the relationship be-tween the denitrification bacteria and the total nitrogen removal amount. The results show:First,cultivation of swamp cabbage is conducive to the stability of the denitrification bacteria growth;second,the denitrifi-cation bacteria have mutual effect with each others;thirdly,denitrification bacteria have a well correlation with total nitrogen removal amount. This provides theory basis for the floating in purifying water quality, and enrich the theory of the floating bed planting technology. 5tabs. ,10refs.
