Abstract:
The separating characteristic of element in cumulate MSW is a very important base to investigate the synthetically managing technology and estimate the water environment effects in Three Gorge Reservoir (TGR). The experiment to marinate the cumulate MSW under 135 meters for TGR in water is finished, and the same time, the Separating Distributing Coefficient (SDC) and the Separating Velocity Rate (SVR) of each heavy metal in water are presented, too. The experiment results show that the SDC of Cd is the smallest, the Ratio for Water and MSW (RWM) and marinating time play an important role in SDC and SVR, the SDC and SVR change smaller while the RWM get to 400, the separating content of heavy metal can reach 0.75 during three weeks, SVR decreases more with marinate time's increasing, and SVR gets an limit value with smaller RWM. The results can be a base for deeply studying the managing technology and the cumulate MSW under 135 meters for TGR.
