Using hourly data to study the impact of precipitation on air pollutants and AQI in 2018 spring and summer in Lanzhou. The results show that precipitation has different scavenging capacity for air pollutants. The sorting capacity of precipitation for different pollutants is: SO2> PM10> NO2> O3> PM2.5> CO. Different levels of precipitation scavenging capacity is also different, heavy rain and micro rain had the best effect on PM10 removal, moderate rain and micro rain had better wet scavenging capacity for O3. Precipitation duration and precipitation are the key factors of pollutant removal capacity.
