[0041] The odor generated by the sewage treatment plant enters the odor treatment system through the fan, and the intake air volume is 300m h -1 , water distribution pipe tap water drip filter capacity 9×10 -3 m -3 h -1 . By monitoring the deodorization effect of the system for 30 days, the main odor pollutant H in the odor 2 The concentration of S is (0.148~0.684) mg·m -3 Between, after being processed by the multimedia system, H 2 The concentration of S is (0.013~0.064)mg·m -3 Between, the removal rate is over 84.5%, and the average removal rate is as high as 91.8%; NH 3 The intake air concentration is (0.107~0.652)mg·m -3 Between, the average is 0.310mg·m -3 , after system purification, in (0~0.081)mg·m -3 between, with an average of 0.040mg·m -3 . Its removal rate is above 75.2%, and the average removal rate is as high as 87.8%. At the same time, the odor concentration is used as the monitoring index, and the intake odor concentration is (977-4121) OU m -3 Betw...
