| Abstract;The basic examination on reduction of phosphorus and ammonia to prevent eutrophication of lakes, marshes and moats, by using construction waste was carried out. Materials used are Autoclaved-light-weight-concrete(ALC) pieces treated and Ooya-ishi pieces made grainy, both of which are construction scrap. As a result of basic examination, it was found that adsorption potential of phosphorus was excellent in ALC treated and that ALC treated also satisfied the immediate effect which was demanded for the phosphorus removal in the stream of waterway. But a problem of pH rise was admitted after the experiment. Effect of phosphorus adsorption of Ooya-ishi was not admitted, but its effect of ammonia was admitted about one-tenth as large as that of Natural-zeolite. (author abst.) |
