Abstract With the development of economy and society, the problem of municipal solid waste is becoming more and more serious. In our country, municipal solid waste after being incinerated still contained much heavy metal as it was not treated by classification. The fly ash is the mainly carrier of the heavy metals. The heavy metal mass fraction in fly ash could migrate and infiltrate into air, water, soil and ecological environment. It's imperative to remove the heavy metal from the fly ash. The objective of this research was to investigate the effect of use with nitric acid in enhanced electrokinetic removal experiment by analyzing the total content of several kinds of heavy metal (Zn, Pb, Cd) in the MSWI fly ash. From the test's results, the total content of Zn, Pd and Cd in the fly ash were 12280.0 mg/kg, 526.3 mg/kg and 124.8mg/kg respectively. After the fly ash was treated by enhanced electrokinetic removal experiment, for Zn and Pd, the content of heavy metal in A2 was the least among A1, A2, N1 and N2, especially for the content of Zn. It is shown from the test's results that acid and time can be helpful for the heavy metal removal in electrokinetic removal technology. In other words, it is possible to conclude that the way of adding acid in the sample zone in electrokinetic removal experiment showed positive effect.
