可提式微孔曝气器在油脂加工行业污水处理中的应用Application of lifting microporous aerator in sewage treatment of oil processing industry

Abstract

曝气器是污水处理好氧池工段的核心设备之一，其通过控制好氧池溶解氧的浓度，使好氧微生物高效分解污水中的有机物，达到净水的目的。通过分析常见曝气器的特点及曝气器安装方式的优缺点，并结合油脂加工行业污水具有高含油、高化学需氧量的特点，选择安装方式为池面悬挂可提升式，曝气器为硅橡胶管式微孔曝气器的组合即可提式微孔曝气器作为油脂加工企业污水处理曝气器，将其应用于某粮油加工企业污水曝气系统的升级改造中，具有污水处理效果稳定、运行成本降低、设备故障率较低、维修便捷、曝气效率高等优势。可提式微孔曝气器在油脂加工行业污水处理工艺中具有较大的应用优势。Aerator is one of the core equipment of the aerobic tank section of sewage treatment, which controls the concentration of dissolved oxygen in the aerobic tank to ensure that the aerobic microorganisms efficiently decompose the organic matter in the sewage to achieve the purpose of water purification. By analyzing the characteristics of the common aerator and the advantages and disadvantages of the aerator installation methods, and combined with the high oil content, high chemical oxygen demand characteristics in sewage of oil processing industry, lifting microporous aerator with the combination of pool surface suspension liftable installation and silicone rubber tubular microporous aerator was chosen as a sewage treatment aerator in oil processing enterprises. There were some advantages such as stable sewage treatment effect, low operating costs, low equipment failure rate, convenient maintenance, high aeration efficiency and so on when the lifting microporous aerator was used in the upgrade and transformation of sewage aeration system in a grain and oil processing enterprise. The lifting microporous aerator has significant application advantages in the sewage treatment process of oil processing industry.
