Concentration Level of PM10and PM2.5in Sludge Dewatering Plant
In summer and autumn, atmospheric particles of two typical sludge dewatering workshops (CY and HT) were collected, and the concentration of PM10 and PM2.5 was analyzed. The results showed that PM10 and PM2.5 of HT points which with poor ventilation rate were seriously polluted, exceeding the limit value of "environmental air quality standards" (gb3095-2012).Seasonal variation of concentration: summer>autumn; the PM2.5/PM10 ratio is above 0.5, indicating that PM2.5 is the main pollutant. The CY point is well ventilated to facilitate indoor particulate emission; HT point ventilation is not conducive to indoor particulate emission. HT points should improve ventilation equipment to ensure workers' health and safety.
