Sulfide malodor deodorizing method and mechanism study in wastewater treatment plant

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.
