Abstract： This study collects soil samples from an arsenic contaminated site， uses a combination technology of particle size separation and chemical leaching to conduct simulated engineering remediation experiments on arsenic contaminated soil of different degrees， and evaluates the remediation effects of different methods on arsenic contaminated soil. The results of the small-scale trial indicate that this combination process ensures the stability of the on-site soil remediation effect. The experiment helps to determine the most economical and effective combination process， select the optimal combination and ratio of reagents， and guide on-site soil remediation engineering practice.

Keywords： arsenic contaminated soil; particle size separation; chemical leaching; remediation effect; evaluation
