生物滴滤床除臭系统净化污水处理厂臭气的研究

Study on Purification of Odors in Wastewater Treatment Plant by Biotrickling Filter Deodorizing System

采用生物滴滤床除臭系统对污泥浓缩池产生的臭气进行进化。结果表明,生物滴滤床除臭系统对污泥浓缩池的主要的恶臭污染物H2S和NH3的平均去除率分别为91.8%和87.8%,对臭气浓度的平均去除率为85.8%。H2S、NH3和臭气浓度的去除效率随温度的降低而降低,但净化系统H2S、NH3和臭气浓度的总去除效率仍能分别维持在84.5%、75.2%和82.2%。

The biotrickling filter deodorizing system was used for purifying odor gases in sludge thickener.The results showed that the average removal rates of H2S and NH3,the main odor pollutants emitted from the sludge thickener,were 91.8%and 87.8%,respectively,and the average removal rate of odor concentration was 85.8%.The removal rate of H2S,NH3 and odor concentration of the decrease of temperature,but the total removal rate of the purification system for H2S,NH3 and odor concentration still remained at 84.5%,75.2%and 82.2%.
