Abstract

 In this paper, first by some laboratory odor tests, it became clear that bottom mud odor of fishing ports and drainage stations that contain a lot of organic rot components is mainly due to the hydrogen sulfide odor of the bottom mud itself and due to the ammonia odor by highly alkaline ground improvement material, and their concentrations were found to be strongly correlated with pH. The following became clear that the optimum pH range for the maximum deodorizing effect of improved mud by PS ash should be within the weak alkali range and the addition of ferrous sulfate was effective in deodorizing. In addition, the results of the confirmed odor test on site improved the odor control function effect by reduction of PS ash adding the curing period and finally the utilization results were obtained.
