摘　　要：盘片式微孔曝气器,该装置曝气气泡直径小,气液界面直径小,面积大,气泡扩散均匀,不会产生孔眼堵塞,耐腐蚀性强,特别适用于城市污水和大型工厂新建扩建和老曝气池改造,盘片式微孔曝气器虽然工艺处理能力显著,但其曝气的均匀性直接取决于盘片式微孔曝气器在施工过程中的安装精度,通过工程实例,利用QC质量管理手段对如何提高盘片式微孔曝气器的安装精度进行分析探讨,解决了盘片式微孔曝气器安装过程常见的质量问题,提高了一次安装合格率,缩短了因返工造成的工期,从而提高了污水处理至达标的速率。The disk-type microporous aerator has the characteristics of small aeration bubble diameter,small gas-liquid interface diameter,large area,uniform bubble diffusion and strong corrosion resistance,which will not cause the mesh blockage and is especially suitable for the new construction and expansion of urban wastewater treatment plant(WWTP)and large WWTP,and the reconstruction of old aeration tank.Although the process treatment capacity of the disk-type microporous aerator is remarkable,its aeration uniformity directly depends on the installation accuracy of the disk-type microporous aerator in the construction process.Through the engineering examples,how to improve the installation accuracy of disk-type microporous aerator by using QC quality management means is analyzed and discussed to solve the common quality problems in the installation process of disk-type microporous aerator,to improve the qualification rate of one-time installation and to shorten the construction period caused by rework.Thereby,the rate of sewage treatment to the standard is improved.
