Abstract:
The odor treatment project of wastewater treatment station in a starch sugar industrial production enterprise has a treatment capacity of 8 000 m3/h. According to the characteristics of complex odor composition and high odor concentration, the odor source is collected by mean of carbon steel skeleton & fluorocarbon fiber membrane. A combined process of alkaline washing & biofilter was applied to treat the odor. The results show that the combined process has high efficiency and stable effect. The removal rates of H2S, NH3 and odor concentration are more than 99%, 99% and 98%, respectively. The emissions could meet Emission Standards for Odor Pollutants (GB 14554-1993). The project has low investment and the operation cost, which could provide reference for the design and implementation of similar high concentration odor project.
