The invention provides an entrance-exit particulate matter purification system and a control method thereof. The entrance-exit particulate matter purification system comprises at least two air blowing purification devices arranged on an entrance-exit channel; the air blowing purification devices can output air curtains perpendicular to an extending direction of the entrance-exit channel; an ion generation device is further arranged in each air blowing purification device; and negative ions can be carried in the output air curtains. According to the entrance-exit particulate matter purification system and the control method thereof, the defects of large size, slow and incomplete treatment and high maintenance cost of the conventional purification equipment are overcome; meanwhile, due to the integrated system scheme, the occupied space of the control unit is essentially different from that of the conventional scheme; and excessive occupation of civil engineering space is avoided. 本发明提供一种出入口内颗粒物净化系统及其控制方法，包括设置于
