中文摘要：

总结了污水厂硫系恶臭治理技术方法的研究成果,探讨了脱臭方法的相关机理.结果表明：采用筛选出的并经驯化的高效脱臭菌,根据所处理硫系不同组分,选择不同菌种,形成二级或多级串联滴滤或过滤处理系统,进行生物脱除硫系恶臭气体,可达较理想的处理效果;以均匀沉淀的化学法制备纳米ZnO,并向其中添加稀土元素铈和铁系元素铁,可获得以室温脱硫效能好、精度高、可满足污水厂室温低浓度含硫气体脱硫要求的纳米脱硫剂.纳米ZnO基脱硫剂粒径小、氧空位多在室温脱硫过程中起关键作用.利用污水厂污泥为原料,添加金属活化剂和相应的辅料,以传统碳化或微波碳化法,可制得效能良好、适用性强的污泥吸附脱臭剂.

英文摘要：

Summarizes the research achievements of different technological methods of dealing with sulfide malodor in sewage plant,and discusses the mechanism of deodorization method,which indicates that the selected and domesticated high-efficient deodorizing bacteria can be used according to their sulfide group differences to form two or more levels of drop filter or filtration system to deodorize sulfide malodor.Nanometer desulfurizer with high precision and capability of desulfuration under room temperature could be obtained by adding nanometer ZnO with REE,which meets the requirement of desulfuration of low concentration sulfurous gas under room temperature in sewage plant.Study shows that the nanometer ZnO with smaller particle diameter and more oxygen vacancy plays a key role in the process of desulfuration under room temperature.Using sewage sludge from sewage plant as raw material,adding metal activator and relevant accessories and using traditional carbonization or microwave carbonization method,we could produce sewage sludge deodorization adsorbent with high efficiency and adaptability.
