 Abstract
Three magnesium compounds, , MgO, and , which are supposed to supply oxygen continuously, were applied onto contaminated bay sediment and its ecology in order to activate the local microbial flora. Those compounds were found to reduce chemical oxygen demand (COD), total nitrogen (T-N), and total phosphorus (T-P). Magnesium oxide, in particular, reduced COD by 30% and T-N and T-P considerably. All compounds also suppressed the release of pollutants in the order , MgO, and . Analysis of microbial flora showed that the microbial group treated by and was predictably stable; meanwhile, that treated by MgO increased the number of species, but decreased the total number of microorganisms.
