- Abstract:
- To address the issue of odors from sewage pumping stations meeting standards but disturbing residents during urbanization, this study constructed and operated a pilot-scale “biological deodorization + molecular sieve adsorption” system at a sewage pumping station in Hangzhou to achieve deep deodorization. The results indicated that under high-concentration and significantly fluctuating odor loads during summer, the combined process achieved an average odor concentration removal rate of 99.46%, with outlet concentrations consistently maintained below 200, demonstrating excellent operational stability. Biological deodorization and molecular sieve deodorization synergistically complemented each other in removing odorous substances. Biological deodorization efficiently removed ammonia and hydrogen sulfide, while molecular sieve deodorization achieved removal rates of 95.06%, 85.82%, and 97.33% for methyl mercaptan, dimethyl disulfide, and hydrogen sulfide, respectively. Furthermore, the combined process demonstrated energy savings, with low energy consumption for molecular sieve desorption and regeneration, indicating strong technical and economic feasibility.
