The dust of bulk goods is the pollutant source during the operation period at the bulk terminal. It has great impact on the environment and requires a high-standard treatment. Taking the 2nd phase of Majishan project for example, this paper expounds the dust proof design which is based on the principle of “energy saving and emission reduction” and “the new replacing the old” in design, and adopts series of simple and effective technological measures. The monitoring data shows that with the implementation of the 2nd phase environmental protection facilities and improvement of the 1st phase ones, the emission of toxins is no longer proportionally increasing but decreased instead. It has achieved the expected results of “increasing production without increasing pollution”.
