摘　　要：结合工程经验确定空气搅拌适用于具有腐蚀性、全地下结构池型等特点的废水工程,并需根据实际水质选定空气搅拌装置材质。为保证空气搅拌效果和使用寿命,在设计穿孔管曝气时孔口直径≥5 mm,孔口流速≥15 m/s。Combined with engineering experience,it is certain that air agitation is suitable for wastewater treatment engineering, characterized by causticity and underground structures and so on. The air agitation materials should be selected according to the actual wastewater quality. To ensure the effectiveness and service life of air agitation, the orifice diameter should be ≥ 5 mm, and the orifice flow rate ≥ 15 m/s, when the perforated pipe aeration is designed.

关 键 词：空气搅拌 孔口流速 废水处理
