Abstract:With the increasing dumping of municipal solid wastes (MST) in Songtao Reservoir Basin by years, it has already become one of the main pollutants influencing the water quality. In order to find out the quantitative influence of the MST on the water environment, the static leaching rules of total nitrogen under different hydraulic conditions were studied as following method. Firstly, the static leaching experiments of total nitrogen were made under water-changing condition and no-water-changing condition, and the experiment models were constructed by similarity theory. Secondly, the static leaching theoretical models of total nitrogen in different water conditions were constructed by significance testing. And finally, leaching rate of total nitrogen was calculated by optimal smoothing distribution, respectively. The results of static leaching experiment indicated that the content of nitrogen in Songtao Reservoir MST was 0.77%. The optimal smoothing distribution was q=208.16-58.49ln(t), q=-25.13+0.842t-0.003t2 from Logarithmic model and Cubic model under water-changing condition and no-water-changing condition, respectively. With the increasing of liquid-solid- ratio, the nitrogen leaching rate increased. The optimal smoothing distributions in this study could predict accurately the total nitrogen short-term leaching rate under different hydraulic conditions.
