曝气沉砂池臭气闭路循环“趋零排放”升级改造
- Title:
- Upgrading of Aerated Grit Chamber for Near-zero Emission of Malodorous Gas Closed Cycle
- 摘要:
- 污水处理厂曝气沉砂池是污水处理厂恶臭气体主要来源之一。基于铁氧化除硫化氢、生物除臭强化工艺，并将处理后气体循环至曝气沉砂池，提出恶臭气体闭路循环“趋零排放”工艺改造设计方案。调试结果表明，铁氧化除硫化氢单元对硫化氢与氨气的去除率分别稳定在92%~95%、40%~50%，生物除臭系统经过调试和挂膜后，对硫化氢与氨气的去除率都稳定在98%左右。在实现恶臭气体闭路循环“趋零排放”的基础上，相比于常规碱吸收工艺，可大幅节省药剂运行成本，并进一步提升污水处理厂区及周边区域空气环境质量。
- Abstract:
- The aeration grit chamber is one of the main sources of malodorous gas in wastewater reatment plant. The upgrading scheme for near-zero emission process of malodorous gas was proposed, including the combination of hydrogen sulfide removal by ferrate oxidation, biological deodorization and closed cycle of treated malodorous gas to aerated grit chamber. The commissioning result showed that the removal efficiencies of hydrogen sulfide and ammonia by ferric iron oxidation achieved 92%-95% and 40%-50%, respectively. The removal rates of hydrogen sulfide and ammonia by biological deodorization unit were both about 98% after commissioning and biofilm forming. On the basis of near-zero emission of malodorous gas in closed cycle, compared with conventional alkali absorption, the operation cost of chemicals can be saved greatly, and the air environment quality in wastewater treatment plant and surrounding area are further improved.
