Abstract
Effect of nitrogen dissolution characteristics of pond sediment by the immobilized EM technology was studied by the indoor simulation experiments in this paper. The results showed that ammonia nitrogen was the main forms of inorganic nitrogen dissolved from the sediment. The release of ammonia nitrogen from the sediment was related to the pH of the aquaculture wastewater. The ammonia nitrogen was escaped from the water with the higher value of pH and the concentration of ammonia nitrogen in water would be reduced. Applying microbial nano-silica balls would inhibit the release of inorganic nitrogen effectively from the sediments to the water and reduce the content of total nitrogen and ammonia nitrogen in aquaculture water. The dissolution amount of inorganic nitrogen was not related with the thickness of sediment for the treatment of CK, but it was faster in the early period with the thicker sediment. However, the inhibiting effect of inorganic nitrogen dissolution was reduced when the sediment was thicker for the treatment of EM nano-silica ball.
